A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Setup: Laptop connected to our network via public WiFi over a VPN encrypted connection.

Trying to map a network drive so laptop user can save files to the server.

This worked one time:
net use k: \\xxx.xxx.xxx.xxx\transfer /u:
Prompted me for my username and password and mapped the drive

Subsequent attempts after rebooting yields a System error 53 network path was not found.

If I do the same command less the /u: parameter it maps the drive just fine but of course I cant get into the drive because of permission issues.

The username on the laptop is not the same as what the user would use if they were on site and actually logging into our network thus the reason for the /u switch.

I'm having a problem trying to remote desktop, with very specific circumstances. With all my HP Probook 430's and 450's, running Windows 7 Professional 64-bit. When they're outside of the domain at a remote site, connected successfully via VPN, they're supposed to be able to remote desktop to various computers inside our domain at our main site. But they can't. Instead I get the general error (attached). But none of the problems in the error are true.

Here are the odd circumstances. I have other machines - HP desktops, other laptops, etc. that can remote in via the same connection from the same remote site. So I know the connection is fine and I know our server-side VPN/firewall is fine. But also, these same HP laptops can remote connect to the target systems just fine when they're inside the domain at the home site. So their remote desktop connection software on the laptops is working fine. But something changes when those laptops go offsite that prevents them from connecting, and I can't tell what it is.

I've tried enabling and disabling the firewall on the laptops, but nothing's changed. I've tried disabling Symantec Endpoint Protection as well. I've also tried using the local admin login instead of the domain AD account login. Nothing's affected the issue.

Any ideas where to go from here?

We would like to set up a WSUS server in our DMZ (Internet Facing) for our external users to get MS updates.  I believe for licensing (EULA) requirements the users would have to vpn into the network to get the approved updates.
This would be managed separately from our internal WSUS server, so we don't need to 'downstream' updates from the DMZ  WSUS server to our internal WSUS server.
Server:  Windows 2016 Std, WSUS v 10.
Any suggested links, information, certificate requirements, etc., would be greatly appreciated.

Thank you,

Hi there, I have created  Windows 7 Hosted VPN (PPTP) and it seems to work OK buit file sharing / ping is sporadic. The connection is almost immediate but I often cannot ping the host or access file shares.

So testing ::
I connect and try ping - no response
I disconnect and reconnect - ping has no response
I disconnect and reconnect - ping reply OK and file sharing work fine -nice and fast
I disconnect and reconnect - ping has no response
I disconnect and reconnect - ping reply OK and file sharing work fine -nice and fast
I disconnect and reconnect - ping has no response
I disconnect and reconnect - ping reply OK and file sharing work fine -nice and fast
I disconnect and reconnect - ping has no response
I disconnect and reconnect - ping reply OK and file sharing work fine -nice and fast

etc etc etc

Any ideas? I don't want my users to have to connect and disconnect and reconnect to get it to work?

Hi,

I'm trying to share a printer via a VPN PPTP Connection. It was working well for a while (although it took quite a bot of work to get it going).

I couldn't share the printer via the computername as it is not recognized but the IP address works (ie. \\IP Address\Printer Share Name\)

So I got that connected properly. However upon disconnecting and reconnecting the VPN connection, the printer is unavailable and I get the error: "Operation could not be completed (error 0x00000bc4). No printers were found"

Through File Explorer I can connect to the IP address and see all the shared folders and printers. The shared folders I can access but none of the printers can connect/install. If It try to right-click > connect I get a:
"Windows cannot connect to printer Operation failed with error 0x00000002."

I tried reinstalling the printer manually (creating a port name) but I get an access denied error.

I checked the printer spooler and disabled the firewall but still can't share the printers.

Any help or troubleshooting idea would be greatly appreciated.

Regards,
Lawrence

Hello Experts

We are in discussion with our ISP to connect the remote branch office with the HQ. We have decided to go with MPLS IP VPN.
Hence, I need know what configuration I need to on the Customer Edge ( HQ and Branch). ISP will provide there router equipment on the branch side.
What information should be provided to ISP ? What IP Subnets and VLANs I need to setup on our layer 3 switches


Please advise me because this is the first time to take this service

Hi experts - this is a follow up from a previous question I had where it was determined I couldn't run a P2S and S2S VPN side-by-side in the existing Azure environment due to on-premise networking limitations.

I've decided that while we're waiting for approval on the infrastructure upgrade, I'll try to configure a temporary workaround using RRAS on the Windows Server 2016 VM.
I've installed and configured RRAS and the SSTP VPN, but am unable to connect to it from outside the Azure network.  I have a Network Security Group in place that allows the appropriate TCP 443 traffic and have checked the SSL binding, but external dial-in clients don't even get communication with the Windows server.

Reading that this wasn't a port forward, more of just a firewall rule, I configured (I think) an internet load balancer with the frontend IP configuration and a 443 rule, and the backend linked to the Windows server.  But I still cannot connect to the SSTP VPN.

Can someone please assist me in getting the correct configuration for connecting to the SSTP VPN.  I'm happy to provide as much detail as needed on the load-balancer settings, NSG settings and VM settings.

Thanks and regards

I want to buy 2 sonicwalls nsa 4500 for testing purposes.  Are there things that I'm not able to do because I do not have a license.  What I really want to get do is setup a VPN connection from my house (uses Charter ISP) over to my dad's house (also uses Charter ISP).  thanks.

What does it mean to be "Always On"?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Hi Experts,

I have created a VPN Tunnel between 200D and 30E.
The 200D has a static IP.
The 30E has a dynamic IP over 4G
Yesterday I created the tunnel with success.
In the evening I switched off the 30E and today morning I booted the 30E again.
I have got a new IP on the 30E and now the tunnel is not coming up.
When I check the IPSEC MONITOR on the 200D I can see the old IP.
Why its not updated ?

I am looking for a software VPN. Main goal is to give my users a way to create a RDP session with their own computer.

At the moment I use Greenbow VPN and a Draytek router which is configured for VPN.

It is a lot of work to setup and maintain. When a modem is Exchanged the VPN does not work anymore.

Think of it like Teamviewer: that passes all routers and sets up a connection. I want to be able to do that with Microsoft RDP in a safe manner.

I have a IPSec tunnel to a remote location. From within the network I am able to access all resources over IPSec tunnel. Users who are connecting in over Cisco's Anyconnect are unable to reach the resources over the IPSec tunnel.

I am trying to connect a Laptop running Windows 7 Professional via VPN (Shrew client) to a Windows 2008R2 Server (Router FritzBox).  The VPN connection functions properly, but I cannot access any shared files/folders on the server.  I tried using tracert and ping to test the connection to the Gateway (192.168.0.2), the router (192.168.0.254), and even a network printer (192.168.0.20).  No response at all, and consequently I never get to the screen to enter username and password.  Ipconfig /all displays an addtional IP address 192.168.0.128 after the tunnel is up (is all traffic then routed through this IP address?).

I have tried this before using an Android tablet.  The built-in VPN client connects, after which I use the AndSMB app (configured with domain, username and password).  I am able to browse the shared folders, upload and download files without problems.

Any hints for troubleshooting the file access problem would be appreciated.  Apparently there are differences between how Windows and Android access the shared folders on the server.

Hello Experts,

Would it be possible for someone to explain to me how a satellite server for updates work, whether it is patching or definitions?  Here's what I'm trying to understand:

The use case applies to remote users who don't connect via a VPN on a regular basis.  Is there a way to push the patch or new virus definition out if the user is not on the VPN? I don't think it matters what application is being used, for example, Altiris for patching, TrendMicro/Sophos, etc. for virus definition, etc.

I have heard of using a satellite server for this use case and need to understand how it works.

Thank you,
Steph M

I've set up RRAS on the server using the Wizard for VPN only.

I've opened up port 1723 in the router pointing to the server. 1723 is also open in Windows Firewall.

Trying to connect a Windows 10 client and it attempts the connection then fails with "a connection to the remote could not be established so the port used for this connection was closed"

I can't find anything relevant googling this error.

Anybody had a similar experience & fixed it?

My company is currently move to a new office.  I have two Sophos SG210 devices.  They were setup using HA for redundancy.  I have stopped the HA so I can take one of the devices over to the new space to setup for some users to move over a week earlier.  I have configured the device for the new internet provider but my question comes to if I create a tunnel between the new space and existing space.  Would it cause a problem is I create a tunnel between the two locations and leave the internal LAN settings the same.  With this scenario the internal LAN's would be the exact same networks so I am wondering if it would cause conflicts.  Our current space also has a VPN tunnel to our datacenter.  I was going to also create a tunnel form the new space to the datecenter.  Would both offices being on the same internal network also cause conflicts with that.  

Or should I just have to change the internal LAN of the new space and enable DHCP on the Sophos for the users that move over early then change the LAN back after the entire move has been completed?

Whats are the benefits of having MPLS- Velo cloud? We are a company with many branch offices and located in diffrent place and all of them are on diffrent domain. None of them are integrated yet. No VPN too. How MPLS will help us in integrating the company to one and how VPN an be setup so that users can work remotely and IT support can troubleshoot issues remotely not have to visit sites physically? Please suggest me. I want to see one domain under one umbrella.

[Live Webinar] The Cloud Skills Gap

[Live Webinar] The Cloud Skills Gap

As Cloud technologies come of age, business leaders grapple with the impact it has on their team's skills and the gap associated with the use of a cloud platform.

Join experts from 451 Research and Concerto Cloud Services on July 27th where we will examine fact and fiction.

I've got a Watchguard 500 series at the main office and a 2 series at a home office.  I've needed to setup a VPN between the two devices to get an IP phone to function properly.  

With the current home office setup I have one interface set as 'external' and connect the cable modem directly here.  Then I have a 2nd interface as 'trusted' which connects to the users home router.  The phone and computer connect to the home router and the VPN works fine.

At the new home office location however the home equipment is a cable modem/router combo - so I have no dedicated WAN port - just 4 LAN ports.

Maybe I'm over thinking this but I'm stumped on how to configure this with the different home router/cable modem combo.

I've been using 'mixed' mode and am wondering if I need to be using 'drop in' mode - ?

So if my understanding is correct from what I have managed to discover, the problem here is that any device connected to a cell phone hotspot, that has an active VPN, will simply route through the public ip connection on the hotspot and not go through the VPN.

Is there a way to 'route' through the VPN any device connected to the cell hotspot?  I have heard that possibly rooting the cell phone may allow this, but I have never rooted a phone before.

Or, is there another way to make this happen?  I am trying to create a secure VPN from our remote offices back to our main office using a cell phone...without having to step up to a LTE router.

New install of Essentials 2012. Configured router to forward 443 to server. Companyname.remotewebaccess.com all works OK. I didn't install a cert and now can't seem to get vpn working. I'm happy to go back and purchase a cert - how do I get back to the wizard. Is it true that vpn won't work on a windows 7 PC or 10 PC without a cert? Sorry - new to essentials :-(

Hi Experts,

I notice of recent that my end users that are connected by a site to site VPN connections are reporting that their Outlook clients are not staying updated and they are seeing a lot of lost connections and re-connections.

I am running Exchange 2013 server and 2010 and 2013 Outlook clients.

Any thoughts?

Hello,
I have a server that is running SBS 2011 and MS Exchange 2010.
We had a power outage, and when the server came back, email didn't.
Yesterday we were able to send email, but not receive.
Today we can't do either.

This system is old, and we are in the process of upgrading to a new server and OS/Exchange - hopefully in the next few weeks - but we need our email up and running today!!

I am currently logged in remotely, via LogMeIn (because the VPN was also reset as a result of the outage - router issues).
When I open the Exchange console, and try to connect to the Exchange server, I get an error - The attempt to connect using Kerberos authentication failed: the client cannot connect to the destination specified in the request. Verify that the service on the destination is running and i accepting requests.

Any suggestions would be greatly appreciated!!
