Hi all,
We are having problems connecting to our RAS server through our ASL firewall. The MS dial up client is setup with our domain details ie username password etc, and set to use MS Chap, MS Chap V2 and PTPP. Within the PPTP options we have disabled support for LCP extensions and for multilink support on a single connection as suggested by MS. The RAS server is set up as default to accept incoming PPTP connections. When trying to connect we get 'connection error #734 PPP was terminated by the remote computer'.
On the ASL box under PPTP logging we get the following information:

On packet filtering we have it set to forward GRE and PPTP to the RAS server.
Does this make sense to anyone? Any ideas would be most appreciated
