Unfortunatelly I already had ip_forward enabled: [root@imoqland root]# cat /etc/sysctl.conf | grep forw # Controls IP packet forwarding net.ipv4.ip_forward = 1 [root@imoqland root]# cat /proc/sys/net/ipv4/ip_forward 1 But still doesn't work :(. I left the whole previous message on purpouse so the original question doesn't get lost. Why is it so hard? I have read the documentation, tried to follow the instructions but it still doesn't work. I think it has been one of the more difficult task latelly. Three days and still no luck :(. Alex. -- ˇSé libre, usa software libre!
