Hi,

I have a major problem with VPN (PPTP, SSTP, L2TP) over mobile PPP links. The connection establishes OK, the ping is 70-140ms and signal strenght on 3G is from -70dBI to -80dBi. The connection stays up untill I start some data transfer. On the main end I have a x86 RoS 5.25 and on the client end RB411 RoS 5.25. I got an advice to create a queue as the problem should be that not all VPN packets are comming to main router. I have tried to make a simple queue and a queue tree. I can see the connection speed being limited, but still... as soon as start to make a data transfer and see the conection speed the VPN connection disconnects (I can still ping public IP from main router) and reconnects back when I stop the bandwidth test on VPN tunnel. Maybe I'm not making a correct queue rule?

/queue simple
add burst-limit=0/0 burst-threshold=0/0 burst-time=0s/0s direction=both \
disabled=no interface=vpn1 limit-at=8k/8k max-limit=10k/10k name=\
vpn-queue packet-marks="" parent=none priority=1 queue=\
default-small/default-small target-addresses=0.0.0.0/0 total-queue=\
default-small


Thanks.
