Trunaa scale networking issues

(part of thi explanation may not be needed as it's how my router handles outgoing traffic, I just included it as context for why it's annoying that truenas is sending all outgoing traffic over a single ip)

I have the truenas network setup like this enp40s0 > br1.

On br1 there are 4 static ip address 192.168.1.2/24, 192.168.1.4/24, 192.168.1.64/24, 192.168.1.117/24

My home router is setup to connect 192.168.1.0/26 to wan and connect 192.168.1.64/26 to wg0

I have the 4 ip addresses set to different apps and it works correctly for connecting to the apps via webui However truenas only seems to select one of the 4 ips at startup and only use that for outgoing connections. So all 4 apps either get stuck using wan or they all get suck using wg0, instead of 2 on wan and 2 on wg0.

Is this normal behavior? I would have thought setting an ip in the app would have the app sending it's data out through that ip. Why is all outgoing data only going over 1 ip? Did I set something up wrong? I'm assuming all the outgoing traffic is being combined in br1 but I'm not sure how to stop it from doing that.

Any help would be appreciated.
