One of my clients had a failed modem so we went in and replaced it with a new Draytek modem and the onsite IT guy decided to use PPPOE passthrough to the netscreen, everything worked with the exception of PPTP htrough to an internal 2003 server.
I have posted the config of the netcreen here, -cfg.txt
Things to note are that the config used to have a MIP from 192.168.110.102 (external port on F/W) through to the 2003 server, this has been deleted as the ext f/w port is now the ISP WAN port. I tired to create a new MIP on that port but it complained about the port being in use already.
The PPTP vpn gets through to Verifying Username and password, but hangs there.
The 2003 server is on 172.22.3.2 or 172.22.3.1.
Appreciate any help with this.
