Just configuring a 2020 with a smoothwall firewall.
I've set the active true IP up, and outbound traffic is working fine.
However, for instance, I'd like to allow incoming traffic on port 25 for email, it would appear that this traffic is being blocked by the router, before it arrives at the smoothwall box.
Could someone help me to turn the firewall features of the draytek off, or show me how to open the ports I need in active true ip mode please?
