I have a gateway to gateway vpn (home-office) working fine for almost an year btw 2 wrvs4400n routers, This morning, the VPN tunnel was down. I clicked "Connect" from the web based interface, but it does not reconnect.
I tried setting up a new tunnel using the VPN setup wizard, but it says it can't connect to the remote router. Which is strange, since I can ping there normally.
I can guarantee you, nothing has changed. I am the only person with access to these routers. The remote location is connected to the internet. The remote router is operating, since I allowed them to connect to the server (at my home), bypassing the VPN while I troubleshoot.
Now, I just asked someone to reboot the remote router (office). So then, I went to my local router and clicked "Connect" on the VPN tunnel and it is now UP.
This is very bizarre, but thanks for the help, problem is solved, I guess, if it does not recur...
