Hello, I am trying to configure the AAA on the Cisco network devices.
The AAA protocol is Radius and the server is Microsoft NPS.

I had to choose the  CHAPv2 as authentication method on the RADIUS server.
The question is, if I need to configure CHAPv2 on each network device (client) as well.

I know, that it depends on the type of the Radius server.

Can anyone advise if this is required for Microsoft NPS as well ?

Thank you.

My wan Ip and public ip are different..Please help me...I first had a dlink router but then I changed my ISP and the router too..Port forwarding was first working but now I tried Port forwarding but its not working..

      I am going for my Network+ N10-006 test this next week and I am having some issues with some subnetting. I need to find faster ways to obtain the following details with IP addresses. I can work them out in the long run, taking a lot of time with converting dotted decimal to binary then comparing the subnet mask to the IP address to find network etc. etc. But the real problem is in my test I will be under the time clock with NO calculator. I have done quite a bit of these and not seeming to get faster at them so I am hoping some of you have some good tricks to help speed it up. I have searched the web too but most of them require excel and calculators which I wont be able to use. Info I need to determine quickly is below.

A random IP, (If you know a quicker way to convert to binary instead of lining up the formula and plugging in 1/0 in the following: 128 64 32 16 8 4 2 1, that would also be super helpful!)

Network ID
First Valid IP
Last Valid IP

      One other thing that is kind of escaping me that I cannot fully grasp yet. If my number of subnets are quite high, like in a /27 that allows me 32 diferent subnet ranges, with 30 valid addresses in each one minus my ID and Broadcast. When you add those up, it goes above the .254 range for the octet and has to increase the octet prior, correct? If so, is there an easier way to calculate these ranges from ID to Broadcast easier then setting down and writing each range out …
Hi all,
This is a bit of a wild ask, but just in case somewhere here has seen this error and can help, as zscaler themselves is not providing a timely answer.

We use the zscaler ZPA private access client to allow VPN like access back to our corporate network.
The ZPA client is on laptops and will allow access from external to all apps that we have defined as being allowed on the internal corporate network.
That works great, EXCEPT for DFS file shares.
Windows DFS just doesnt work at all.
Normal UNC fileshares work fine. No problems with UNC.
But as soon as users try to access DFS file shares, there is no access. The request fails on the laptop.

We have contacted zscaler and have an open job with them, but this is taking weeks to resolve.
So long that we are looking at dropping ZPA entirely and go with something we know works, like Microsoft Direct Access.

Moving all the remote users to UNC file shares isnt an option, as the file sharing environment is complex and the amount of manual work needed for a workaround of UNC paths is unacceptable.

Can someone tell me how to permanently set a Hyper-V hosts network adapters to Domain or Private?  I managed to do it on a 2012r2 host but can't find the article - this is for a 2016 HV Host.

Replication fails whenever I reboot unless I manually use PowerShell to set the adapter as Private..

Many Thanks,
Hi All Expert,

Good Day.

I am tasked to help outside vendor on SonicWall NetExtender VPN setup and don't have much knowledge on this SonicWall NetExtender, I went to the official website and was shock that it does not have the download for windows. The firewall is Sonicwall and I was given the IP address and domain though, windows 10 I know can download the SonicWall Mobile Connect, but I need windows 7 as well. Appreciate if any expert here have SonicWall VPN experience can assist me on.

One of my win10 laptops can connect to the internet but cannot see other devices in my network. Even my television can see all the wireless devices in the house but the laptop can't. My other win7 laptop can see everything as well. My win10 desktop is hardwired and wifi connected to the router and can see the other devices but if I unplug the cable the other devices disappear. All the usual network things are turned on such as network discovery. Can anyone help as this has been going on ever upgrading to win10.

How to convert tib file from Acronis to iso file ?

Is there any tools that able to achieve this?

Hi, we got internal Storage device-VNX 5400 having Source host ip and on other end of MPLS network which is in other site got same Storage  device-VNX 5400 with Destination host ip At source end we got ASA 5520, so due to this replication is very slow due firewall as it was modifying the traffic, its impacting replication performance.

Please help me how to pass through the traffic from ASA 5520 at source end. so that it helps replication between storage devices on both ends on MPLS network will be faster. At present replication transfer rate is 340 Kbps and our bandwidth is 40 Mbps

Hi expert

How to execute an Automated script to copy the Network files and send over to a specific users by outlook email?

Question can this achieve by powershell.
My NAT policies for single ports are working, but when I try to use a port range it is not working:

I am trying to use the following details:

object service Support-Ranges
service tcp destination range 50802 50814

object network Server-SupportRanges
nat (inside,outside) source static any any destination static interface Server-SupportRanges service Support-Ranges Support-Ranges

Running a packet trace passes the ACL and fails on Phase 7 NAT

I'm trying to add a single queue 'csqFabFursEscal' in the working UCCX script (FabFurs_Working.pdf).  I've made changes in an attempt to add the queue in the broken script (FabFurs_broke.pdf) and it doesn't work.  Everytime I load the broken script into my test application I get a system message saying their are problems and to call back.  

This isn't a complex script and I know this is an easy solution for someone better at scripting.  I would really appreciate a UCCX scripting guru take a look.
I have some Windows users with Skype for Business 365 Online. They occasionally get the message "Your connection is causing audio quality issues. Speeding it up might help. Try closing programs that are using the network and stop and downloads or uploads." It's not a network issue have looked closely at other metrics and non-windows Skype users don't have this issue. Is there any way to prioritize Skype for CPU and/or network? Thanks!
I'm supporting a site where a relatively new HP Officejet 8520 is set up as a network printer using a wireless connection to the network.

It appears that all of the computers can print OK.
As I recall, I removed all of the old printers when this one arrived.
And, I installed the FULL software from a fresh HP download.

It's a common task to scan pdf to a computer file - controlled from the computer side.
At times this "breaks" and the printer won't scan from the ADF.  I'm not sure they tested from the glass directly.
I've tried a number of things to fix this but the problem is elusive.
Today, they rebooted both the printer and one of the key computers and now everything is working again.

The failure mode is that the HP Scan software just hangs when asked to actually scan.

I see that using HP Scan on the computer will allow the selection of .pdf output.  But, the same type of setting on other scan interface software only will do .bmp and one othere non-pdf format.  No pdf selection is presented.  This seems odd and is inconvenient when testing.

- the printer is bad but intermittently so.
- the wireless connection isn't adequate to support scanning - whether that's due to the wireless system or the printer's wireless interface.
- the computer software needs to be reinstalled (again?)

Any suggestions re: how to get past this intermittent failure?
I have a user that according to effective permissions had Delete.  The share permissions are set so authenticated users have modify.  The user can create, copy,rename,edit.  But when they try and delete the file it says you need permission to perform this action, You require permission from domain\user to make changes to this file.  The domain\user is the user that is having this issue.  If I give this user permissions to logon to the server it self, he can delete the file no problem.If the user login to a terminal server as the user, the user can delete the file.
For security purposes we are removing Domain Admins from our IT Staff accounts.  So we need a way to iterate through all of our network drive folders and find all folders that have granted Domain Admins rights and duplicate those rights for our group called IT.  Would anyone know how to accomplish this in powershell or otherwise?

I have a flat network with a subnet
There are a dozen printers from HP Deskjets to Toshiba plotters and MFP's.
All are connected to a DC running Server 2012R2.
Customer is complaining about print jobs timing out or printing several copies of the same job when it does print.
From what I see it could be related to the "Enable bidirectional support" option on the port tab of the printers properties.
But all of them are grayed out.
This is a Hyper-V VM.
So I tried a fresh install on the physical box of one of the printers and have the same issue even with the latest drivers.
Dear experts, we are testing pfSense firewall but could not access it via LAN network on a PC. This is our diagram:
ISP ------------- pfSense ---------------- Core switch 3750 ---------- PC

with this diagram, we could ping and access pfSense via web browser :
ISP -------------- pfSense -------------- PC

So I guess something wrong with the core switch and vlan setup, but we could not find why. In switch 3750, the interface connected to pfSense has access mode, vlan 100 - the same with pfSense LAN interface.

Could you please suggest?

I am currently battling with getting an SSTP VPN setup on my test network and wondered if I am missing something.

I had a 2008 Server which ran SSTP however this was on a single a server which also had Exchange and AD installed. An SSL cert was purchased for Exchange and the same cert was used for SSTP.

I have a new server which now has Hyper-V installed and I am running a DC and Exchange server both on Server 2016. I have installed the certificate for the exchange server and that is working fine however I am trying to use the same certificate on the DC for setting up SSTP. I have imported the cerfiticate as it says on various pages however the drop down menu with RRAS (see image below)

I don't do that much with certificates that often and it might be that I am missing something however I managed to set this up on server 2008R2 with no problems however I am wondering if that was because everything was on 1 server which simplified things?

Any help or tips regarding this or certificates would be much appreciated.
Hey Experts!  Just wanted to run a scenario by someone.  I have MX100 load balancing with two internet up links by different providers (Comcast - Coax and ATT - Fiber) but my ATT is my primary and manages the site to site VPN as well as client VPN connections.  The DMARK for my Comcast is in the IDF while the DMRAK for my ATT is located 300 ft from my IDF, so we have a Ethernet run from ATT DRMAK to my IDF.  It's long I know but under the 328 ft.  

My ATT up-link started having issues a few weeks ago.    Finally was able to talk to a tech from my ATT and confirm that the Lan port was having disconnects.  My Meraki device doesn't log any issues but it continuously fails over to Comcast provider.  I will be testing the Ethernet run Friday to determine what the issue is.  As I see it these are my options in order of preffrence:

1.- Move my ATT DMARK to my IDF
2.- Run Fiber from my ATT DMARK to IDF
3.- Run/replace Ethernet from my ATT DMARK to IDF

for the moment, not preferred, but I may run a vLan from a switch located near my ATT DMARK to my IDF.  Not ideal but should fix me till I get a permanent solution in place.  Any holes in this option?
I am having trouble with a couple things in regard to the following.

I Have an ASA where Cisco anyconnect users that connect to reach resources on the network. however, they are not able to reach anything over the tunnel that is from the ASA to the Checkpoint FW. everything else is just fine.

Is there any main "Gotchas" with Cisco ASA to CheckPoint firewalls?

Thank you.
