Firewall issue maybe its me :)

[jamie2000uk]

I have four external IP (wan)

I have one external IP port 25 which is proxmox gate way
I setup another external IP with proxmox gateway

So at this point both have different external and internal IP both on port 25

EMAIL Gateway 1 Working 192.168.10.16
Email Gateway 2 not working 192.168.10.18

Now when I test the record and this points to the correct externa; and internal IP it wlays try to use gateway 1

Now im guessing this has something to do with the way I have it configured 

I have attached screen shot
