NAT rule with port translation
I am currently using no-ip Mail Reflector to work around Verizon blocking port 25. Additionally, I am migrating from Ipcop to pfsense 2.2.
In Ipcop, I have setup a simple port forwarding rule:
TCP DEFAULT IP : 8025 => 192.168.3.5 : 25(SMTP)
I am learning to use NAT rules.
Currently, my mail server is residing on its own interface (i.e. Orange) along with other servers (Web etc)
So far, I have created a new NAT: Port Forward rule.
I have chosen:
WAN under interface
TCP under Protocol
192.168.3.5 in the Redirect target IP, I have chosen SMTP under redirect target port.
Where do I enter 8025 as the port number I want to translate? does it go under Destination port range or under Source port range?
does it go under Destination port range
