It is skype - and about which "messenger" are we talking? There are several with similar names but using different ports. > Network > > eth0 get dynamic ip address from the router(192.168.11.4) > eth1 FC3 local dhcp server (IP:192.168.1.1 GW:eth0) Which "router" are you talking about? Besides the FC3 gateway host there exists another router? 192.168.11.0/24 is the net between the FC3 host and the real internet connection device, right? Why does the FC3 host for eth0 get then a dynamic IP? Switch over to a static IP. 192.168.1.0/24 is your internal net, means between the FC3 gateway and your other LAN hosts? Why does eth1 get a dynamic IP? Use a static one. Why a gateway setting for eth1 pointing to eth0? After changing the IPs to be static ones for both ethernet devices please post the /etc/sysconfig/network-scripts/ifcfg-eth[0,1] contents. Be sure you have set GATEWAY only in /etc/sysconfig/network, and there it is eth0. > I run > iptables -t nat -A POSTROUTING -o eth0 -s 192.168.1.0/24 -j MASQUERADE You can leave out the source net instruction. Run "service iptables save" to make this rule static and loaded automatically each time the iptables service is started.

Which nameserver settings and gateway settings do the hosts inside the LAN have?
