Hi peeps,
I have a RG450 with 2 WAN connections from 2 different ISP's and is set up as load balancing. I am trying to send email from LAN to one dedicated WAN1 so I don't have to keep having to hitting the send button on the email client multiple times for it to go through.

Any help with the one way port forwarding from LAN to WAN is appreciated. I have read through the hairpin routing threads but I dont think this applies in my case
Cheers,
Scotty

You can probably use a mangle rule to force the traffic from one LAN IP to a particular ISP.
