Hi,

I have a problem with the site-to-site vpn connection between two servers.

Both systems are running W2K3 SP1 + updates and ISA 2000 Server SP2.

Between them there is a PPTP site-to-site vpn.

VPN connects ok, normally within 4 seconds when dialed.

From DC01 I am able to browse all resources on DC02 but I cannot access any resources on DC01 from DC02.

Using a client vpn connection I am also able to browse all resources on DC02 but not on DC01.

Partial log is listed below.

What am I missing here in the ISA 2000 config, as it seems that it is blocking the access.

Both subnets are listed as local in the ISA config.
