I'm having some difficulty getting outgoing traffic from my network routed to the desired WAN ports on my ER8411 router. The router is configured with five public IPv4 addresses. I have a policy route configured for all of my WiFi devices that use DHCP-assigned IPv4 addresses. I have a second route configured for a server that uses a static IPv4 address. I have a third route configured for a second server that also uses a static IPv4 address. Load balancing is enabled. Here's a screen shot:

Each source is an IP Group:

The IP addresses are configured as follows:

The servers are working as I expect. When I USE curl on Juno to determine the address I get the public IPv4 address for SFP WAN/LAN3. When I use curl on Marauder to determine the address I get the public IPv4 address for SFP+ WAN/LAN2. The problem is that when I hit a "what's my IP" site from a PC on the Home network (whose private IP address is in the range shown above) I see a public IP address that isn't the public IPv4 address for SFP+ WAN1. It's one of the other configured WAN ports. How can I configure the router so that traffic sent from the Home network is sent from SFP+ WAN1?
