Dear colleagues,

i'm getting grey hair because i can't find the problem.

I have a AP (Routerboard) connected to a 2Mbit/s leasedline. I have a PPTP Tunnel between the AP and us. We use a MTU of 1400 to be on the safe side. Everything is working but when i do pings from us to the AP via the PPTP Tunnel i get 1-3% Packetloss. If i ping from us directly (outside of the Tunnel) i have no packetloss.

I have absolutley no idea where to look at. I already disabled all Simple Queues that are on the PPTP Interface on the AP.

Nothing helps.

Maybe someone else is expiriencing the same problem or has an idea where i can look.

Thanks.

Regards,
Joerg
