If you want to enable conntrack for Linux you will need:
1. A Recent Kernel, I know anything later than 2.4.20 can work fine.
2. Kernel patches from pptpclient.sourceforge.net if you want the
firewall itself setting up the pptp tunnel, if not, ignore this step
3. CVS download the netfilter code from netfilter.org
4. Apply the patch-o-matic directory to your kernel sources directory
like so:
# KERNEL_DIR=/usr/src/<kerneldir> ./runme extra
5. Apply all patches that you really care for, but I would recommend
anything that doesn't fail out on your configuration.Make sure to
include the connectrack patch
6. Build the kernel with the new netfilter options turned on as modules
7. Install Kernel
8. Execute the following every time you want pptp (once per boot):
# modprobe ip_conntrack_proto_gre
# modprobe ip_nat_proto_gre
# modprobe ip_conntrack_pptp
# modprobe ip_nat_pptp
