Hi,
I can see A routing through B to GW fine. The tunnel bat0 on A and B seems unstable though. I'm looking at VIS packets arriving at PC. It arrives for about 30 sec then stops for a while. It is not clear why the tunnel keeps disconnecting.
thank you for reporting this bug. As Axel already pointed out the blackhole detection falsely kicks your gateway connection. Therefore I added a check for services that don't send data back as the vis server and snmp. If you know more services to ignore please let us know.
Could you re-test with the latest revision ?
Regards, Marek
