Unable to send and/or receive mails using port 25

ThomasGumpinger

Hi all.....

 

I'm facing a strange problem here. I just set up an internal mail server ad applied the smtp business rule. However, no email will go out or come in. The XG Firewall simply does not listen on port 25. If I manually telnet to port 465 or 587 it works, however port 25 ist completely dead.

 

I'm running SFOS 16.05.

    Hi Thomas,

    Check #1 in my guide here. What do you see in the drop capture logs for the SMTP traffic?  Also, guide me through the network structure at your end and show me pictures of the configuration.

    Thank

    The firewall external Interface (Port1) has the fixed ip address 77.119.246.57 and is the mx for the domain digicoach.at. The LAN interface of the XG box is 192.168.205.1

     

    inbound mails work fine...

    The real mail server is in the LAN zone with the IP 192.168.205.20. 

    If I try to telnet any server on port 25,425 or 587 from 192.168.205.20 int will be intercepted by 77.119.246.57
