Strange VPN behavior

Hi folks,

The Microsoft VPN suddenly stopped working, it was working.

I can establish a VPN connection from inside and everything seems to be
working. I can also establish a VPN connection from outside, but I can only
access the VPN server and my lan. I can’t access servers behind the VPN box
and can’t get out to the internet.

It seems that there is some routing problem, or the box can’t handle some
routes to vpn users.

Any idea what can be the problem?

Here are few lines from IPRouterManager.log

posting the routing table here may help.
