RV042G difference between bandwidth <-> protocol binding for WAN ports

[Ryan Hendriks]

Can somebody explain a little bit better then the manual what the differences are between bandwidth management on WAN ports and protocol bindings?

If you can specify in each section which protocol should go where why having two places to configure this?

Or are there some things to remind when using one of them?

Protocol binding affects how outbound traffic leaves a particular WAN interface.

With bandwidth management, you specify the overall WAN bandwidth a service is allowed to use.

Even if I tell the router to use bandwidth priority for SMTP to WAN2 (and i do not have protocol binding active for smtp to wan2) it still goes to wan1, how does the router choose this kind of behaviour?

Your particular bandwidth management rule is only used to ensure that SMTP going through WAN2 will not exceed its allocation. It does not stop SMTP from going through WAN1.
