Daniel, I have couple of questions here to help to close on to the cause of the problem. Does it happen [ping stops working] in any case (when ANY of the links fail)? You might consider [both scenarios] setting only one link to be tunnel between your LANs, and see what then will happen with ping, this test scenarios might help: LAN1 -- BRIDGE1 -- Wireless Link -- BRIDGE2 -- LAN2 or LAN1 -- BRIDGE1 -- TINC vpn tunnel -- BRIDGE2 -- LAN2 Regards, Zoran --- Daniel Gheorghica <gheodan@xxxxxxxxx> wrote: > Hi all, > I have to use STP function between too bridges.
