still not forwarding
i restaert my whole box
the routing is now disabled

i check drakconf
a reanble routng
it wont work
i reconfigure it
routing is again working
but the line ive added to shoreall rules goes away

some told me 2 do like console

iptables -t nat -I PREROUTING -i eth0 -p tcp --dport 5000 -j DNAT --to 192.168.1.2:5010

this is finally forwarding my ports

you need to put those "iptables" commands in a bash script and call it from your rc.local so that its executed every time at boot.

Something like this in a file called rc.firewall....
------------------------------------------
#!/bin/sh
insmod ip_tables

echo " Enabling IPFORWARDING ... "
echo "1" > /proc/sys/net/ipv4/ip_forward

#Add your commands below here

-------------------------------------
Put all that in a file called rc.firewall, chmod 744 on it, put it in /etc/rc.d/ then add this line to the end of /etc/rc.d/rc.local/

sh /etc/rc.d/rc.firewall

what does your rc.firewall and rc.local files look like?

what are the permissions on rc.firewall?
