Unfortunately my router is combined with the DSL modem effectively a single
CPE.

I have just come across some information that says that the connection
tracking support for PPTP connections in particular is now part of the
mainstream kernel ( >= 2.6.14 ).  I am currently downloading version
2.6.18-3 and will let you know how it goes.

 

PS. I'm using CentOS which probably isn't the best choice for hacking things
to pieces - guess that serves me right.  I believe debian (Sarge) has
support for pptp_conntrack in it already so I might give that a go as well.

 

If you're interested I am more than happy to discuss this matter off the
mailing lists, but perhaps may serve a better purpose by being on the lists
for future reference for others.
