multiple pptp clients behind one machine

[Josh Logan]

I have compiled a 2.6.9 kernel with the pptp patches.  When I try out the
new modules GRE is blocked on the firewall.

Shorewall:net2all:DROP:IN=eth0 OUT=
MAC=00:a0:cc:56:b8:5c:00:10:67:00:1f:04:08:00 SRC=x.x.48.2
DST=x.x.116.164 LEN=61 TOS=0x00 PREC=0x00 TTL=52 ID=36900 DF PROTO=47

I'm running debian unstable.  I patched and installed the new version of
iptables.  I'm using the patch-o-matic-ng-20050307.tar.bz2 and most recent
iptables source.

The modules load OK:
root at router-jl:~# lsmod
Module                  Size  Used by
ip_nat_proto_gre        3264  0
ip_nat_pptp             4512  0
ip_conntrack_pptp       6336  1 ip_nat_pptp
ip_conntrack_proto_gre     5632  2 ip_nat_pptp,ip_conntrack_pptp


Do you have any ideas, or need more information that I can provide?

Thanks.
