Dear Experts, please help us this case:

We are using Cisco Router 3925 as the gateway for LAN users, users' IP addresses were NAT overload via the interface that connect to the ISP; however we got a network (192.168.50.0) that could not access a website.

If we NAT static a PC inside that network to a static public IP address (or a pool of public addresses), the PC could access the website; but if we did not NAT static and using NAT overload via gateway interface, PC could not access website.

Do you know why? Please suggest

For PAN FW's OS upgrades in HA active/passive mode.  Can anyone point to the process steps?
Does it required to suspend HA first or doing passive first then failover to the active node?  
Please advice or point to the right link.  Planning to upgrade to the latest 8.0.8 release for PA-850 models.

Hello Everyone,

I have a SoniWALL NSA 3500 that I am trying to configure to open port 8000 for a Network Video Recorder (Hikvision). I want to port forward.  I created an object for port 8000 and then for the internal IP address that the recorder is going to use. I then went through the Public Server Wizard and and entered the internal IP and then the wizard went ahead and added our WAN address and then created the inside, outside and loopback parameters.  For all intents and purposes this should have opened port 8000 once I went through the wizard.  

Issue is when I try accessing from outside (or even inside my LAN network) using our WAN IP and then adding the 8000 suffix (x.x.x.x:8000) it's not reachable.  I believe I should receive at least a SonicWALL test page, correct?  Even if the device is not plugged into the switch yet I should still get something from the SonicWALL I believe.

Can anyone tell me if there is anything else I can do to make sure that port is open?  Web tests still say the port is closed.

Any help would be most appreciated!

Thanks!

Hello Experts,

Our Main and Branch Office is connected via 30 Mbps MPLS IP VPN . The internet services are centralized at HQ. We have got two separate internet circuits at HQ dedicated for Business and HQ.
My requirements will be as follows as per the attached diagram
- Guest Internet traffic should go through via FW1
- Corporate traffic should follow default route  currently configured on L3 switch at HQ
- To configure Policing on Branch Office L3 switch. Corporate Traffic 20 Mbps and Guest Traffic 10 Mbps

I would appreciate any help and suggestions.

Hows everyone's experience with Palo Alto Networks Premium support?  Do they pickup the phone 24/7?  How is it compare to Cisco SmartNet support?
We were on hold for critical issue with pan for 30 min elevator music.  By that time we figured things out and ended the call.  Doesn't look like quick enough.

Anyone experienced the same or better?

Hello All,

I'm in need of some guidance regarding a new project I'm about to start. To give you a little background I handle about 15 different clients. My larges client only has 3 servers and about 30 users. For the past 15 years I've handle very small business with one or two servers. The routine admin stuff for small domains.

This new project belongs to my oldest client that has started selling franchises thought out the united states.  They estimate about 30 new sites in the next 13 months. I have very little time to create a Network Operations Center. The company expect to add 30 sites a year or more to a total of about 300. so far 15 have been sold but contsturctions will not start for another few months, so I guess this is really happening.

As you can imagine I'm a little bit out of my comfort zone.

My main question is how to handle the data. Right now we have 4 centers with a PDC and a BDC out of corp office. All connecting through vpn to corp to access files (mostly excel and word). Each center has 6 computers and all centers have about 25 MB of bandwidth. No real problems from about 10 years with this setup.

My intent is to build the infrastructure for 200 sites with 6 computers in each site. I want to divide the country into time zones and create a domain in each time zone. I was thinking a PDC and BDC per zone and VPN from each site. I know I'm really behind the times on a lot of this stuff and there might be a better way to handle this.  All …

Hi

How to setup up a new domain Controller.

I have been replacing antiquated equipment with unifi APs and switches.  I have a sonicwall that breaks my feed into 2 subnets.  One of them is content filtered for a school and the other is for church offices.  I would like to install a USG for the latency and throughput info, but can't seem to figure out how to get it to work without it interfering with SW or APs.  

Is there a way to do it?  I can buy another so that each subnet can have its own.  What I can't do is get rid of sonicwall or two distinct subnets as the school has to have the content filter and USG doesn't have enough of that capability.

I have changed IP and tried it on both subnets.  I have tried it before the SW and after.  I have adopted it, and it brings everything down.  I have adopted it and get caught in a provisioning loop.  It know shows managed by another device.

Thanks,
Pat
PS not an IT prefessional, doing this to save my school money and getting them the best technology possible!  So small words and simple answers please.  I have putty, but need step by step help

Where do I go within the SonicWALL TZ600 router interface to view which licenses have been purchased?

I have a client with a Sonicwall TZ 215  (SonicROM 5.0.5.6 ) that is using a SonicPointN for wireless access. The SonicPoint is setup on Physical interface X2 with a 192.168.17.0 network and the X2 interface also has two VLAN Sub-Interfaces on it, X2:V18( 192.168.18.0) and X2:V19 (192.168.18.0). These VLAN’s are used to create the two wireless zones, one for Guest and one for employee’s. The customer now wants to add a remote lighting “Hub” that is manipulated via an Android or iPhone apps. Even though the “Hub” is accessed via the internet the initial setup has to be done with the phone app being able to see the unit on the same local network segment. Since the hub only has a Ethernet jack and the phone only has wireless, the phone and the hub need to be on the same wireless network. So I what I am trying to accomplish and can’t seem to get working it make the X3 interface on the Sonicwall be on the same VLAN Sub-Interface as the wireless access point. In this case that would be X2:V18. So to sum the whole deal up.  I need to get X3 interface assigned to the same network (192.168.18.0) and the VLAN-Sub-Interface as X2:V18. I can’t seem to get it the way I need, no problem getting the X3 on the X2 network (192.168.17.0) but not on the X2:V18. Any help would be appreciated. Thanks

Appreciate step by step guide on how we can use Solarwinds to

a) issue commands in batch (ie to all the hundreds of servers & Cisco devices)
    & collect back the outputs all in one file   : I used to have one HP central management tool that could do this

b) the OS commands I plan to send out are:
   Windows are :  "hostname; wmic qfe list"
   Solaris are     :  "uname -a; showrev -p"
   Cisco are       :  "hostname; show ver"

Our MS SCCM is used for PCs only so can't use it

Hi Expert Team,

I need help to automate a SQL database alert generated from SCOM . We used to get an alert  'database backup should be performed' for SQL database servers. But in our project we have Always-on cluster(Mirror) database servers and database backups are performing on Primary  database servers. But SCOM is complaining the same for secondary databases and many such alerts are generating from SCOM.  All these SCOM alerts we receive as incidents in ticketing tool via Orchestrator2012. Our goal is reduction of  such incidents. Therefore i want to automate this kind of  alert to identify which is primary database and trigger alert for only primary database servers and not for secondary database servers. . Is it possible to resolve within SCOM console or can we do anything in Orchestrator2012.

Please guide me how to automate.

Thanks for support!!!
Regards,
Sreenivasa

There's request to open up ACL (audit command language) tool to Internet from an internal zone server (ie not in DMZ) for periodic licensing validation.

 if we go through bluecoat proxy, will it work & is this considered secure?  Or it's better this server is moved into DMZ (but this is not an option as this server's
IP will change & we have to unjoin it from AD as we don't have an AD in our DMZ or rather it's blocked)

 Planning to restrict to specific URL for outgoing only (or is incoming port required too)?

We have an ATT Arris 5268AC gateway that had dynamic IP internet service and was passing traffic flawlessly to a Sonicwall TZ400.  Last night traffic stopped being passed.  When connected directly to the gateway with an independent client (desktop) we can get WAN access and see our public IP no issues.  ATT convinced us to buy a block of static IPs to fix the problem but no luck.  I need to 5267AC to pass all WAN traffic to the TZ400 as no user behind the firewall have any WAN access at the moment.  We are on our failover comcast circuit at the moment but need to resolve this.  The Sonciwall provides DHCP and inherits DNS from the WAN.

Hello EE, We have Honeywell handhelds and we've set them down in the warehouse and lost them.
I'm looking at the following: https://www.thetileapp.com/store/tiles/mate?defaultproduct=mate-1-pack&utm_campaign=702894687&utm_source=google&utm_medium=cpc&utm_content=213401926926&utm_term=-&adgroup=47867352387&gclid=EAIaIQobChMI_JjI3JLs2AIVkhuBCh3SqgB7EAYYASABEgLEnvD_BwE

but concerned if the Bluetooth will interfere with the handhelds ability to connect to WIFI if they are fixed to the handheld.
Anyone use these and can speak to it?

Due to legacy design, our Management VLan (where consoles of various servers, ESXi hosts, devices including WAF & Firewalls) are open to users to ssh/ssl in (though password will be prompted).

There's an urgency to fix this: I heard this VLAN sits on either the core or distribution Layer3 switches & not behind firewall :  to migrate it to behind firewall is going to take time & we may not have enough free firewall port/leg.

What's the fastest & safest (ie without causing disruption when making change) to get this VLan filtered/protected (pending firewall being purchased which will take a while) as it's considered quite a risk.

I suggest to put ACLs on the distribution/core switch but my netwk admin objected, saying core switch's function is
for fast routing/switching & we should not put ACLs as it will slow down the routing/switching.  He further argued that such ACL can be complex & accidentally blocked dynamic routing protocols (EIGRP & OSPF etc), causing disruption.

Our core & distribution switches sit in the same Nexus chassis.

Dear Experts,

I went to the cisco website to find the latest firmware for my client's router.

Currently the firmware is isr4300-universalk9.03.13.04.S.154-3.S4-ext.SPA.bin

In the downloads, i found:

3.13S
- 3.13.8S(MD)
- 3.13.7S(MD)
- 3.13.6aS(MD)
- 3.13.6S(MD)
- 3.13.5S(MD)
- 3.13.4S(MD)
- 3.13.3S(ED)
- 3.13.2S(ED)

I deduce that my client is using 3.13.4S(MD)

My account does not allow me to download 3.13.8s(MD) but I can download 3.13.7S(MD) but I am not able to review the version's release note, I clicked on the release note link and it brought me to https://www.cisco.com/c/en/us/support/ios-nx-os-software/ios-xe-3s/products-release-notes-list.html which I do not know which document to look at. As I cannot find the release note for 03.13.7S.

Can anyone please help me on this?
