Hi,
in response to the reported kernel panics when using IPsec VPN and the traffic shaper at the same time in 1.3b6, I've created a fixed version 1.3b7 that includes a kernel patch for that issue. Also, the SIP proxy now works correctly when using PPPoE/PPTP on the WAN interface (thanks to Markus Rosellen for reporting the problem!).
You can get 1.3b7 from
