I'm having some Problems setting up NAT Translation with a Mail and Web Server.
I have an ASG 220 Running ASG v.7 in place behind our router and communicating actively with the outside world and internal clients, Masq. is working perfectly.
Going in the opposite direction however is giving me some trouble.
I need to forward 1.2.3.4/29 :25 (the WAN IP Address assigned to the MX Record of our Domain) to 4.3.2.1/16 :25 (Our Internal Mail Server Address) I was planning on doing this using DNAT but for the life of me I cannot get this record working.
the DNAT Record looks like
Traffic Selector: ANY - SMTP - 1.2.3.4
Destination: 4.3.2.1 - SMTP
so any SMTP traffic destined for 1.2.3.4 should be forwarded to 4.3.2.1
are there any more steps that I'm missing? I confirmed that there is not a packet filter rule in the way.
Thanks
