Linksys RV042 VPN connectivity problem

Have a VPN connectivity between our branches using Cisco 2800 router and Linksys RV042. Everything was working fine, till I tried to make some changes in NAT and Port forwarding on RV042. Finally I undid the changes, but VPN stopped working. Status is 'waiting for connection'. Restarted and verified everything.

Settings seem to be the same, but the VPN is still down. I can not ping the Public IP of RV042 from Cisco 2800, but it is accessible from outside. Similarly, can not ping Remote gateway from(2800's IP) RV042.

Could it be a firmware corruption? Please help.

I assume the configuration has been restored to the original configuration ? I have set up dozens of RV042's, and on a couple of occasions I have found making a lot of changes when "tinkering" has resulted in lost connections such as you have described. The only solution I have found is to do a hard reset (hold the button on the back of the router) and re-configure all over again.

Tip #1:  :-)  When you have a working config, back it up. If you ever have to a hard reset, or replace the router it only takes a couple of minutes to restore the config.

Not the solution you were looking for? Getting a personalized solution is easy.

Before trying that, I wanted to confirm it is the problem with RV042. When I trace route RV042 IP from Cisco Router, it goes up to Broadband router IP (which is connected to WAN port of RV042) and stops.

The problem with hard restting is, it is in a remote place. Non-technical people will be available for a short time. Could there be a block on the ISP side? (on the RV042 side?)

It is possible, but unlikely it would coincide with your adjustments. If someone is available at the remote site first have them unplug the power to the modem and router for 5 minutes, then plug the modem in, wait 1 minute and then the router. That might clear it up.

As for the log, I am not very good at diagnosing from the logs but "Ignoring Vendor ID payload " to me indicates the router is refusing the connection, probably due to an incorrect parameter such as pass-phrase or encryption setting. Are you sure it has been reset to the previous configuration?

Restarting did not work. Asked the person at the other end to hard reset it.
After that, they are able to ping 192.168.1.1.
Telnet 192.168.1.1 gives something like SME boot..
But, http://192.168.1.1 is giving 'page can not be displayed'  error.
They have the Setting backup as 'exp' file. Asked them to import it from the Web management.
Don't know why web management is not working.
Any idea how to proceed.

I have had Linksys routers become completely dis-functional before. As a matter of fact an RVL200 did almost the same thing to me last week. It must be a little bit common as Linksys supplies a repair tool/method. Seems you have to re-install the firmware when you can't get to the management console. However, to do so you need their little TFTP utility. The TFTP utility allows you to install the update remotely. Very simple and works well. It is available from:
  ftp://ftp.Linksys.com/pub/network/tftp.exe 
It comes with .pdf file instructions. You will also need the firmware file, I would recomend the most recent:
http://www.linksys.com/servlet/Satellite?c=L_Download_C2&childpagename=US%2FLayout&cid=1115417109974&packedargs=sku%3D1115416833192&pagename=Linksys%2FCommon%2FVisitorWrapper
I see the TFTP tool is now available from that site as well.
Once updated you should be able to re-import your .exp/config file. It will wipe the current configuration, and also it needs to be done from the lan, not over a remote WAN connection.

Sorry Rob, for not posting earlier. We were able to access web management page, I sent them the .exp file, asked them to import. It worked. Don't know why it did not work last time.
Thank you for your help.
