Hi... I just installed SME7pre3. My server only has one interface, so I used "server" mode. This server has a private address that is being statically NATed to a public address via our internet router. I managed to configure it so I can SSH/HTTP from the internet, but I cannot get an SMTP connection. It seems I can only connect to port 25 from the private LAN side.
I want to open this up so it accepts mail from internet. Do I need to add a second interface and switch to "Server/Gateway" ? Or is there some way to accept smtp connections from anywhere ?
