I have to enable pptp traffic through my nat box (2.4.24, iptables 1.2.9, 2 interfaces (eth0 - private IP, eth1 - public IP)). I have compiled kernel (and iptables )with pptp-conntrack-nat.patch from patch-o-matic-20031219 with following options to kernel config:
... Networking options <*> IP: GRE tunnels over IP [*] IP: broadcast GRE over IP ... Networking options -> IP: Netfilter Configuration -> Connection tracking <*> GRE protocol support <*> PPTP protocol support ...
and it is not working. Right now i can not post a log from tcpdump ... Is there any possibility to check what contrack modules are switch on in working kernel ?
ps. any ideas ?
