May gumagamit po ba dito ng Pfsense? I am trying to configure my on-prem mail server in Pfsense but I can't seem to make it work. I have setup the following configurations pero hindi parin maka send and receive ng mail yung server.
- DNS records pointing to public IP
- Virtual IP (IP alias) pointing to public IP
- NAT port forward rules
- NAT outbound rules
Baka po may makapag help salamat!
