iptables: Invalid argument with PPTP conntrack enabled

iptables: Invalid argument with PPTP conntrack enabled

[Oleg Savostyanov]

Hello,

Iam trying to build the system, capable of making NAT for pptp
connections
Debian 3, Kernel 2.4.22(with debian patches) patch-o-matic 20030912

I found that if I apply PPTP patch to my kernel and compile it with
GRE protocol support and
PPTP protocol support
the simple command
iptables -t nat -A POSTROUTING -o eih0 -j SNAT --to-source $myIP
failed to execute
with the following:  iptables: Invalid argument

May be it's a bug in a patch-o-matic PPTP patch?
Is there anybody, who succeeded building the system capable of
masquariding more than one PPTP connection to one server
outside your lan?

please report such problems to netfilter@lists.gnumonks.org, or
netfilter-devel@lists.gnumonks.org (like documented on
http://www.netfilter.org/contact.html).
also, which version of patch-o-matic were you using?

Martin Josefsson is the patch-o-matic maintainer, maybe he can help you.
