Cisco 881 and RVS042 VPN Down

Hello - I have a Cisco 881 and RVS042 that connect to each other using an IPsec VPN. The connection has recently dropped. While I have experience with the RVS042 interface, I do not have command line Cisco experience and I need to get this VPN restarted.

According to the RVS042, the connect says "waiting for connection". So, Im guessing the main Cisco 881 router needs to initiate the connection. If I click "Connect" it just comes back to "waiting for connection".

NOTE: Nothing has changed on either router with respect to their original working configs. So this might just be an issue where I need to restart the tunnel but I dont know how from the 881 command line.

I can also get access to the 881's command line if that helps.

Thanks in advance!

As it turns out, the 881 did have a firewall rule dropping incoming traffic. Explains why I could ping from it to the 042. Removed it and all is well. Thanks for the recommendation.

We have numerous RV042's (not RVS042) in place and once in a while they get locked in that state.  The connect 'button' does not always re-establish the connection but powering off for 60 seconds does.  It might be worth a try.  The 881 is a more dependable it and less likely to be the source of problems.
