I have a new RV345 which I updated to 1.0.03.16 right after initial setup. It is replacing an RV320. I have a site-to-site VPN that was working perfectly between the 2 RV320s (one here, one remote). I can only get the VPN tunnel to work if I specify the Remote Identifier Type as Remote WAN IP and specify a fixed IP address. If I set the Remote Identifier type to Remote FQDN and specify the name of the remote site it fails to connect.
My problem is that both ends of the VPN tunnel use dynamic IP address.
This works fine with the RV320s but they have become unstable since the last firmware update and they are now EOL.
Any suggestions would be helpful.
