I'm trying to connect a location with a Cisco RV042 router, to a branch that has a Cisco RV180.
A standard gateway to gateway VPN, with a twist: in both locations I have an ADSL router and the two Ciscos are behind them. I can't switch the ADSL routers to bridge mode, so I put the Ciscos in DMZ and forwarded ports 500 and 4500. I've enabled NAT traversal in RV042, could not find the option in the RV180.
Tried for a few hours to make them connect, no joy. Can you please look at the configuration and see if you spot an error? From the logs, looks like phase 1 completes successfully, then phase 2 never finishes.
I had to use a FQDN (dyndns domains) because the IPs on the routers are not public (the public IPs are on the ADSL routers).
