I have got Windows machines behind a Red Hat 9.0 Linux router (with SNAT +
CIPE-VPN). The problem i'm getting is that the machines behind that router
can't open ftp sites. The error message is "__ Invalid PORT command" (and
for some sites there is one more error message " __ command not
understood"). However, the router itself can open ftp sites.
Can this be a problem with ip_conntrack or something else?
Have you loaded the ftp conntrack and nat modules?
/sbin/modprobe ip_conntrack_ftp /sbin/modprobe ip_nat_ftp
