I have setup PPTP on my ASL box and a client on my XP laptop. From inside the network I can connect perfectly and get authenticated. However, if I try to connect from the internet, I get:
2005:05:24-13:10:26 (none) pptpd[16226]: CTRL: Client 141.152.37.27 control connection started

On the internet I am sitting behing as smoothwall box which should be wide open for ports. When I set all this up, I used the PPTP guide at the documentation site.
Thanks all...
