I need a IPChains Guru still alive to convert an IPtables statement

mfeoli · 01-25-2005, 11:05 AM

What I need is to convert the following to ipchains

IPT=/sbin/iptables

EMULE_TCP=4662
EMULE_UDP=4672

TARGET_PC=192.168.0.2

## Creating eMule rules for (PREROUTING in nat)
$IPT -t nat -A PREROUTING -i eth1 -p udp -m udp --dport $EMULE_UDP -j DNAT --to-destination $TARGET_PC:$EMULE_UDP
$IPT -t nat -A PREROUTING -i eth1 -p tcp -m tcp --dport $EMULE_TCP -j DNAT --to-destination $TARGET_PC:$EMULE_TCP

any input will be greatly appreciated

Been awhile, but I believe you need to use ipmasqadm, as ipchains couldn't do port forwarding like iptables. You need to get ipmasqadm and then do something like:

/usr/sbin/ipmasqadm portfw -a -P tcp -L $EXT_IP $EMULE_TCP -R $TARGET_PC $EMULE_TCP
/usr/sbin/ipmasqadm portfw -a -P udp -L $EXT_IP $EMULE_UDP -R $TARGET_PC $EMULE_UDP

See here for more info on port forwarding under ipchains:
