SMTP soll auch über VPN erreichbar sein

IT Services26

Hi,

momentan läuft der intern smtpd auf der UTM auf allen interfaces. Das möchte ich gerne beschränken auf LAN und eben VPN, sprich Site2-Site VPN. Bei der Konfiguration der SMTP Interfaces kann ich aber das Site2-Site nicht sehen. Ist ja auch logisch, da kein Interface da ist. Beschränke ich SMTPD auf  "Internal LAN", dann kann der Remoteserver nicht zugreifen. Wie löse ich das Problem? Für mich ist in allererster Linie wichtig, dass der SMTP nicht mehr an den WAN Interfaces lauscht.

    Hi ,

    Thanks for reaching out to the Community! 

    You can limit the SMTP proxy's listening interface by adding a specific interface at Email Protection > SMTP > Global > Listen Interface.

    Listen Interfaces:

    By default, the SMTP proxy listens on all interfaces on ports 25, 465, and 587 for incoming email traffic.

    To listen only on a specific interface, select the option Custom Interfaces and add interfaces to the Allowed Interfaces box.

    Is this the option you were looking for? 

    Thanks,
