Tie smtp (port 25) to specific WAN on dual WAN Router

[gspillane1]

Hi,

I have a RV042G.

I wish my outgoing mail, specifically port 25, to go via WAN 1.

How do I do this?

Best Regards,

Geoff

UPDATE

Ok after a lot more research I discovered "Protocol Binding". I was still a little confused because I didn't know what "Destination IP address" to use. I finally found an example where they just used 0.0.0.0 for the destination, which for us uninformed means "Any" IP address. So I simply used the listed service SMTP (25), locked to WAN 1, and all worked perfectly. I was able to extend this for use with other ports such as 587, 465, by adding these to the list of services. For accessing a cPanel I also added a range of 2082 to 2096 because without doing that I kept getting an error saying my IP address had changed and to log back in.

I hope this might help someone else.

Hello Geoff,

Sorry for the late reply to your topic.

Just as an addition (yours or somebody else's having the same question) you can refer to this guide and especially to the "Manage Protocol Binding" section:

Hi Milan,

No need to apologise as I know you guys can't be across everybody's posts all the time. You do need a life too.

I did find that guide and it was a great help but the example destination IP addresses shown in the guide where it was talking about Protocol Binding only confused me further as I couldn't see how I could use any such IP addresses. Fortunately I found somewhere else that someone in a similar position used a destination IP of 0.0.0.0 and stated that this represents "Any" IP address, which I didn't know but was appropriate for what I wanted.

Best Regards,

Geoff

Hello Geoff,

Yes, you are right and the explanation you found is correct.

In the networking, the address 0.0.0.0 (sometimes a configuration of a subnet mask of 0.0.0.0 is also needed) is considered "anywhere outside of the current LAN" or simply "the internet".

Kind regards,
