Scenario is:

WAN1 Line 1 - Internet Provider - Port 25 goes in and out and is MX1 on domain name
WAN2 Line 2 - Internet Provider - Port 25 goes in and out and is MX2 on domain name

I have an issue with line 1 and email routing as the MX has an issue. BUT.. mx 2 is meant to take care of this.

But I cannot get the 2nd ip to route ip to the SAME mail server. Is there some ip table mapping going wrong somewhere.

No clever mapping.. Just 2x lines and some port redirection going on... NOT even vpn.

Why would this not simply work after putting in port redirection rules to WAN2

IPS are all good.. I can remote manage the router on the WAN2 IP so I know it is getting to the router, but then NOT to the mail server.

Please help asap
Many thanks in advance
