I am new to pptpd and have an unusual situation. My office gets its internet connection from an mpower partial T1 through an Adtran Total Access 608 T1 ATM. The Adtran specs says its IP router supports NAT/PAT, packet filtering, RIP V1/V2, Layer 2 PPP, and Frame Relay. My local Class C network uses static IP's in the 10.0.0.0 to 10.0.0.255 range.
A few weeks ago I had mpower open up port 1723 and GRE to allow VPN remote access to my network.
All worked well when I used an XP Professional box as the server. Worked flawlessly, in fact.
I then installed 5.6, and upgraded to 5.6u3, on an older box (celeron 466 w/256mb ram) I didn't use anymore. I even followed the instructions regarding the pptpd bug.
All seems to be well with the SME box except it can't be reached from the internet. I know the pptpd is working because I can connect to it locally. And I know that the firewall is configured to let VPN in because I can reach my network remotely if I reconfigure XP to receive VPN.
I never had both SME and XP set to receive at the same time.
Thank you for any help or suggestions,
A.J.
