I have an RV042 site-to-site VPN set up. The VPN shows that it's connected at both RV042 ends. The subnets at the sites are different. If I ping across the VPN, the traffic seems to bounce at the source LAN end. A tracert shows the path going first to the VPN and then bouncing to the default gateway for the source client - as if the RV042 VPN refused the packet. I've tried various RV042 firewall settings from none to rules which allow traffic between the LANs and between the public IP addresses on the WANs. Nothing seems to change the behavior. The frustrating thing is that this used to work as I was building up the capability. .... not finished yet. It also works "in the lab". I can remote into both ends of the VPN to change settings, and it's not yet "in production", so it's pretty easy to try things.
