I encountered a weird problem at one of oure smallbiz networks.
First i shall explain some topology:
LAN A<----------->SBS2003prem<.------>Draytek vigor 2300
<------>Speedtouch510 (pptp)<-----> Internet.
We have the right network settings on the SBS machine. I've set up an lan to
lan interface to a other network.
Lan A ip: 192.168.5.0
Lan B ip: 192.168.1.0
This lan to lan VPN (PPTP) is working fine. Lan A clients can connect to
internet and to Lan B.
But the SBS server can't connect to internet if Lan to Lan is connected.
There is no static route that points 0.0.0.0 to the <lan tot lan> interface.
The only static route is 192.168.1.0 255.255.255.0 Interface: <lan2Lan>.
everything else is working.
