ip forwarding 1 machine to another

omle · 09-29-2011, 11:49 AM

Hi

have spent many a good hour trying to get this to work and now im not sure that i can, what im trying to do is forward connections made on one machine a specific port to a different ip address (different machine)

ive tried

Code:

iptables -A FORWARD -p tcp -i eth0 --dport 27960 -j ACCEPT

iptables -t nat -A PREROUTING -p tcp --dport 27960 -i eth0 -j DNAT --to xx.xx.xxx.xxx:27960

also have tried to use rinetd which also didnt work

the machines are located in different parts of germany they are gameservers im trying to forward all who connect on the old ip straight to the new ip and port instantly but just cant seem to get it working,

any help would be gratefully accepted

thanks

Hello!, try with:

Code:

iptables -t nat -A PREROUTING -p tcp --dport 27960 -i eth0 -j DNAT --to-destination xx.xx.xxx.xxx:27960

and

Code:

echo "1" > /proc/sys/net/ipv4/ip_forward
