RE: pptp and nat

["Darrell Dieringer" <netfilter@darrelldieringer.com>]

Hello,

Others are certain to have more experince with PPTP that I do.
However, if you believe it is a rules-related problem (as in some
packets needed by PPTP are getting blocked), make sure you have a
LOGging line before every DROP rule (or at the end of chains with a
default DROP policy).

There may very well be a PPTP helper module that you need, though.  I
don't know since I haven't tried to use PPTP through netfilter myself.
I only brought up the LOG/DROP scenario since you hadn't mentioned
checking the logs for problems.
