I'm trying to set up ftp all within "local" sites that are connected via RV042 VPNs.
I've selected one site for testing the ftp server.
I can log into the local server at 127.0.0.1 and at the server's LAN IP address 192.168.1.xxx.
However, I can't log into the server from 192.168.2.xxx over the VPN.
The VPNs have been working for a long time and support all sorts of traffic. e.g. I can ping from other sites to the ftp server just fine.
So, something seems to be getting in the way of the ftp.
Each system has a local firewall and they have been set for incoming and outgoing ftp traffic on ports 20,21.
