PPTP and GRE

["Jan Kaastrup" <jka@xxxxxxxxxx>]

Hi list

I am running poptop on kernel 2.4.23.
I need the patch, that makes it possible for GRE to do NAT

I remember i have done it before, but not how :) 
In my ip_conntrack the gre protocol stands as "UNKNOWN", and remember i
have seen it says "gre".

Any help will be appriciated

Thanks a lot.
