hello,
I try to get a kernel 2.4.18 with patch-o-matic-20030107 running.
But i have some problems with the conntrack helpers. They simply
don't work .. *sigh*
i tried ftp, irc and h323. I compiled as module and kernel included,
same result..
normal masqerade works, i can do passive FTP, irc, http, normal stateful
inspection, etc..
i hope anybody can help me..
-------------
here is what i have / see:
FTP conntrack problem:
bash-2.05# cat /proc/net/ip_conntrack
tcp 6 431573 ESTABLISHED src=172.30.255.1 dst=10.20.0.17 sport=1572 dport=21 src=10.20.0.17 dst=10.20.10.197 sport=21
dport=1572 [ASSURED] use=1
EXPECTING: - use=1 proto=6 src=10.20.0.17 dst=10.20.10.197 sport=0 dport=1573
The sport=0 seems wrong to me..
my system:
