Hi folks,
I have some strange problem with IP forwarding.
Recently I did my work Firewall clean update (migrated from RedHat to
Slackware kernel 2.4.21 with the same configuration like RedHat) and after
this
does not work forward of IP 47 (gre) and tcp 1723 (PPTP) to local network.
The error messages you can see below:
tcpdump -i eth0 | grep pptp
tcpdump: listening on eth0
