It looks like you’re trying to forward port 25? Then you must use “standard network RED” as source instead:

I noticed that you also set the source port to 25. Most clients use randomized source ports. To allow these clients to connect, the source port must be left blank.

P.S. don’t forget to click “apply changes” :slight_smile:

Hi,

as @luani mentioned already, please read the firewall documentation before asking for help here, as your problem is already answered there.

Thanks, and best regards,
