Hi

I used speedify bonding software when I'm travelling around which allows me to bond together multiple connctions such as wifi, 5G, USB etc

This works fine with my legacy Wireguard VPN client, I can access my internal network fine (windows laptop).

However with Netbird, I find I can't get to any internal network IP addresses, internet is working but I'm unable to reach my secure / tunnelled networks. If however I stop using speedify, then netbird works and I'm able to hit private ranges.

I don't see what netbird could be doing differently to not allow it to work with bonding software whereas standard plain old wireguard works fine? I thought netbird used wireguard under the hood anyway? I know the routing is different but it seems there some kind of clash between speedify and netbird, and its a bit frustrating as I would prefer to use netbird than standard wireguard.

Any ideas of what I can do to troubleshoot?

Thanks!

Jon.
