I have a MT x86 running as a PPTP concentrator with about 35 connections using 2.9.51. All remote sites are MT. I have one remote that will not connect. It just says dialing… link established. Over and over.
I have checked the settings and passwords.
I am wondering if this one being behind a linksys router is the problem.

Now that we got that out of the way. Any useful suggestions?
check that your Linksys passes GRE protocol
That must be it! After looking up “linksys gre protocol 47” I see that others have had success forwarding port 1723 even though the linksys does not support gre pass through. I will attempt and report.
forwarding port 1723 fixed the problem
glad to hear that =)
pptp always uses GRE (proto 47) and tcp/1723. you need both.
GRE passthru is necessary when you have more than 1 tunnel client behind the same router, because it’s harder to differentiate one GRE destination from another (no port numbers to pair things with).
Ok, well there is only one in this case. Thanks for the help.
