Understood. This still does not allow a PPTP session to passthrough NAT
. This stopped working in v3.0 release candidates. It worked in v2.9.
More accurately this is a double NAT
situation. The customer behind the MT has a SOHO router, Linksys, Netgear, DLink, etc... If that customer is NAT
'd through the MT then they can not get a successful PPTP session (even with the aforementioned PPTP Service Port/helper). If this customer is removed from NAT
and given a routable IP then PPTP works correctly. We have a large number of customers that we have to remove from NAT
and assign a routable IP address to when we upgrade a site from v2.9 to v3.0. Also we are only using the MT as a router, no wireless cards, no MT AP, no MT CPE.
