VPN Suddenly stopped working - 17.Dec.2007 4:35:26 PM

Hi,

I have an SBS 2003 server Premium with ISA 2004 setup on it.

Up until a couple of days ago it all worked fine, now the VPN clients cannot connect.

When i run the logging on the ISA/SBS server i get the following error message;

Failed Connection Attempt
Log Type: Firewall Service
Status: No connection could be made because the target machine actively refused it.
Rule: Allow VPN client traffic to ISA server
Source: External (xx.xx.xx.xx:18024)
Destination: Local Host (80.194.xx.xx:1723) <-- Internet Address not DHCP
Protocol: PPTP

The only thing that concerns me is that the destination local host is on the external interface and not the internal one. I am not sure if this is a problem as i never looked before because it worked.

Any help would be greatly appreciated.

Thanks in advance
