Is your OpenWRT router running in vm on the same host or somewhere
else
throughout physical network eth1?
The OpenWRT is a completely separate device running at the end of the
cable connected to eth1. The Wireless is also connected to an AP on
that router. All of this is on the 192.168.1.* network.

Try something like this ti get your vm settings.
virsh -c qemu:///system dumpxml ${GUEST_NAME} | egrep -A5 -i
"network|bridge"
i.e.
virsh -c qemu:///system dumpxml Buster | egrep -A5 -i "network|bridge"

<mac address='52:54:00:1b:07:7c'/>
<source network='default' bridge='virbr0'/>
<target dev='vnet0'/>
<model type='virtio'/>
<alias name='net0'/>
<address type='pci' domain='0x0000' bus='0x01' slot='0x00'
