SonicWALL TZ170 keeps timing out during configuration

I am trying to configure a site to site VPN between TZ170 and SonicWALL 2600. The problem I am having is that when I go to configure the TZ170 it keeps dropping the LAN connection.

I have to unplug and plug back in the router in order to get back the LAN connection. But it only last for about 30 seconds before it drops again. I have a continuous ping going on my console computer to see when it drops and it like clock work after 30 seconds I have to unplug again. What could be causing this to happen.

I have the TZ170 connected to a Comcast router LAN on port #1 and my console computer is plugged into port #2 and I am connected to port #1 on the TZ170. I am able to get to the SonicWALL config page but by the time I navigate to the VPN page to configure connection drops.

Please help.
Thanks!

See if you can do a firmware upgrade on the problem router. If the firmware is up to date, make a note of its configuration and do a hard reset back to factory specifications. Set it up again. If it continues to quit after 30 seconds, it may have a hardware problem.

John,

In my attachment it shows that my firmware has been upgraded. I did set it back to factory and it is still happening. I replaced it with another TZ170 and it is doing the same thing. Not sure what is causing it but I don't think that there is anything with the hardware.

Thanks

Two different Sonicwalls probably eliminates hardware.

You are try to manage via VPN.

1. Does the router drop its connection every 30 seconds when checked locally?
2. Have you got a very short timeout in VPN?  Normal is dropout after 15 to 20 minutes of no activity.

Where do I check that in this router?

Plus... I do not have a VPN connection established yet.... I can't get it to stop dropping before I can configure it.

So per your second comment, VPN has nothing to do with the dropout. That means 2 routers are dropping connections at the ISP. I would ask the ISP and get them to change the modem.

John I appreciate your help.

I thought about that also, so I disconnected the TZ170 from the Comcast router and tried to just configure the router from my laptop:

1. Changed IP address to 192.168.168.20 on Laptop
2. Plugged CAT5 from Laptop to LAN port on TZ170 (#1)
3. Entered 192.168.168.168 in browser
4. SonicWALL config page displays
5. Login using default credentials
6. Clicked on the VPN tab. As I start configuring the Site to site connection page stops displaying, connection lost. It's like the TTL is set for a minute. It shouldn't be like this. And it is happening on both TZ170's.

Frustrating.
Thanks!

Can you try this with a different laptop. It is beginning to look if the laptop is the culprit. Either that or VPN is badly misconfigured. Can you rebuild the VPN profile?

I tried this with my desktop also... nothing still same behavior.

I cannot believe two different computers drop connections to two different routers the same way.

What VPN are you using? It must be completely misconfigured.

I reset to default yet again.... I still can't get through the Wizard setup before connection drops. This is happening on both routers so it has to be a setting somewhere that is controlling this.

But I can't figure out where to make the change.

I even tried putting the Comcast router in Bridge Mode still no change.

JohnBusiness Consultant (Owner)Commented:
You have two computers. You can hook up either router to either computer (without VPN) and the connection drops.

Please take one router and do a hard reset back to factory specifications and try that.

You said this  "2. Plugged CAT5 from Laptop to LAN port on TZ170 (#1)"  which means you connected from laptop directly to router bypassing Comcast.

Was your statement true?

CervisTECHAuthor Commented:
John,

Yes my statement is true. I have already put both router back to factory default with no results. Statement #2 was on the Laptop, I was following the direction of the users manual in setting up the router. I am an experience Cisco engineer, this is my first time working with a SonicWALL router, it's not difficult I am just never seen a router time out like this during the initial setup before. I thought maybe someone at this site has seen it before.

But from the looks of it this is new to you also.

I will continue my troubleshooting hopefully I will find the answer.

Thanks!

I wonder if you have two bad SonicWalls. I have not seen a router I could not manage with a direct laptop (computer) connection.

You might wish to contact SonicWALL support.

Hi John,

I just want to give you an update on the problem I was having. I found out what was causing the time out issue. It was the power cord. I was using the wrong power when I plugged up the routers. Each time I swap router I continue to use the same power plug. The voltage wasn't correct.

I  took the power from the other box and noticed that they looked different plugged it in and the problem went away.
