Could it be that ip_forward is disabled on tinc-srv02? Or maybe brige
traffic filtering is active without the required firewall rules?

/proc/sys/net/ipv4/ip_forward
/proc/sys/net/bridge/bridge-nf-call-iptables

I am not aware of any unusual network setup requirements for tinc.

Are you sure that this works? I understand tun devices to be layer 3 interfaces
- thus they cannot be connected to a bridge (layer 2), as far as I understand.
