Surely this should be possible, but I'm just not finding the answer.
Given the following:
I have 2 BATMAN-Adv wireless mesh networks (WMN) running on separate 5 GHz channels, and a primary network. All 3 networks are in the same subnet (192.0.0.0/8).
I have a single board computer (“SBC”), acting as a bridge node between these 3 networks with 1 ethernet (eth1, eth0 is reserved and not in scope at this time) and 2 wireless NICs. The ethernet port is wired to the control room network (“Ctrl Rm Net”). Each of the wireless NICs are nodes for their respective WMNs (bat0, bat1).
Both WMNs seem to be operational, and ‘batctl -m bat0 o’ and ‘batctl -m bat1 o’ showing the full complement of connected devices on each.

| +-----------+
| +-------------+ | /-+--wlan0--((bat0))
+--+ Ctrl Rm Net +--br-lan (eth1)--+ SBC br0 |
+-------------+ | \-+--wlan1--((bat1))
+-----------+
Symptoms:
I believe that I am getting packet collisions or a cycle, because if I disable the interfaces wlan0 and wlan1 in /etc/config/network, the SBC can ping 8.8.8.8 successfully. However, this fails when these interfaces are enabled.
Also, a computer (192.0.0.13) on Ctrl Rm Net can ping eth1 at 192.168.1.100, but it cannot ping wlan0 (192.168.1.101) or wlan1 (192.168.1.102) nor any devices on either WMN (bat0 nor bat1).
Goal:
I need all 3 of these networks to communicate seamlessly.
