Yes, see:
# modinfo ip_conntrack_ftp
filename:
/lib/modules/2.4.20-20.9/kernel/net/ipv4/netfilter/ip_conntrack_ftp.o
description: <none>
author: <none>
license: "GPL"
parm: ports int array (min = 1, max = 8)
parm: loose int
You can define the ports when loading the ip_conntrack_ftp module.
Cheers,
Ralf
