So I'm setting up the RV320 so port 25 is forwarded to an internal Exchange server.
The RV320 hangs off of a cable modem, and there is no firewall on the cable modem.
I went into Firewall / Access Rules. I created a rule that Allows SMTP, source interface is WAN1, Source IP is ANY, and Destination is set to the IP of the Exchange Server. Scheduling is set to Always. Here is a snapshot: https://i.imgsafe.org/a366195062.jpg
But external port checking from ShieldsUp from grc.com shows all in Stealth. Port 443, for some reason, shows Closed.
Works great as a gateway for internal PCs, but ports aren't accessible from the outside.
Under Setup/Advanced Routing, the Working mode is set as a Gateway. I think this is right.
Or am I missing something else?
