I have a Cisco RV042G router, set up for load balancing on two equal Internet connections. I have set up protocol binding to route specific traffic from the local LAN for certain IP ranges/ports onto specific WANs. One reason I needed to do this is that OpenVPN clients wouldn't work unless the traffic was fixed to one of the WANs. Another reason was for my TMobile mobile phones, where I used their firewall rules to bind the WiFi calling to a specific WAN, as without it, calls were getting cut off.
How do I verify that the router is moving the traffic for specific IP/ports onto the WANs I specified?
traceroute won't work - it uses ICMP and that isn't affected by protocol binding.
