21.7 Legacy Series / Forward SMTP from Internet to LAN using IPSec
« on: November 23, 2021, 12:24:57 pm »
Hi!
I have OPNsense (21.7.5) running on a machine having an public (static) IP.
Now I'd like to forward incoming SMTP to my private mailserver in my home-network which is connected using IPsec like:
Internet -> Public-IP:25 -> NAT -> IPSec -> Private Mailserver
Traffic from OPNsense flows fine through IPSec-Tunnel.
Unfortunately, the Port Forward from WAN-Address:25 to the LAN-Address of my mailserver does not work.
Can anybody give me a tip how to set it up?
Edit:
* Port Probe using Source Address "LAN" to Mailserver works fine.
* Port Probe using "WAN" to Mailserver does not work.
Thanks!
