Help with possible w1 leak

Hi, I am a bit confused on the route10 bridge interfaces. can someone explain to me why a device I have on L3 (instanton switch) sees the ip starlink gives me on WAN port W1 ?
attaching all related screenshots. is routing gone wrong ? and what is eth3 ? is this w1?





Decided to take a look at my site that has a Route10 and Instant On switches and I can also report that it’s detecting the “Uplink” IP as the public IP address assigned to the Route10. Not quite sure why that is the case at the moment!

I’m also not quite sure how the Instant On switches are pulling information for the uplink device, although I might suspect LLDP or something along those lines. Looking at other Instant On sites with switches, I can see that the switches either don’t list Uplink information at all, they just list a MAC address, or the list the name and internal IP address of the next hop device. For example:

or

The above picture being the name and IP address of the next switch in line.

I might see if I can keep poking at this to get a bit idea of how and where the switch is pulling that IP from the Route10.

Also to answer a quick question, eth3 is the internal port name for WAN1.
