a question about IPMasq and NAT firewalls

[LoRdMaUL]

In the past...when I have been using my Linux box as a firewall...I noticed I was able to receive files from my Windows box on mIRC and the other programs but not send them. Does anyone know a way around that? Any help would be appreciated.

more recent versions of iptables (1.2.4 and above) include ip_nat_irc and ip_conntrack__irc modules which can be *loaded as modules* with up to 8 port numbers of your favourite mirc servers. Once loaded these modules will allow DCC send and recieves. PLEASE NOTE with certain windows IRC clients you must let the *server* provide your irc client ip address as other functions will pooch the nat / conntrack functions.

[root@katrina /]# locate ip_nat_irc
/usr/include/linux/netfilter_ipv4/ip_nat_irc.h
/usr/src/linux-2.4.18-3/net/ipv4/netfilter/ip_nat_irc.c
/lib/modules/2.4.18-3/kernel/net/ipv4/netfilter/ip_nat_irc.o

[root@katrina /]# locate ip_conntrack_irc
/usr/include/linux/netfilter_ipv4/ip_conntrack_irc.h
/usr/src/linux-2.4.18-3/include/linux/netfilter_ipv4/ip_conntrack_irc.h
/usr/src/linux-2.4.18-3/net/ipv4/netfilter/ip_conntrack_irc.c
/lib/modules/2.4.18-3/kernel/net/ipv4/netfilter/ip_conntrack_irc.o

ok...I apparently have those modules....and I apparently have version 1.2.5-3 of iptables

would you be so kind as to tell me how to load the modules to make this work?

any help would be appreciated
