so, I installed fresh FEDORA 13 on the firwewall server, set up eth0 (for internal) and eth1 (for external), set up the rc.firewall, reboot, but.....
I can ping my own IP: 192.168.2.1 but cannot ping any other internal IPs, like 192.168.2.x
Also, from 192.168.2.x cannot ping this server 192.168.2.1
CAT IFCFG-ETH0 says:
DEVICE=eth0
HADDR=x:x:x:x:x:x
IPADDR=192.168.2.1
GATEWAY=192.168.2.1
NETMASK=255.255.255.0
IPV6INIT=no
BOOTPROTO=static
TYPE=Ethernet
ONBOOT=yes
On RC.FIREWALL I have:
${IPTABLES} -A INPUT -p icmp -j ACCEPT
${IPTABLES} -A OUTPUT -p icmp -j ACCEPT
Need desperate help :(

WTF ?!!?
IPADDR=192.168.2.1
GATEWAY=192.168.2.1
That makes no sense.
Post the output of
ip addr
ip route

Hi
Managed to make it work on eth0 (internal network interface)
still cannot ping outside on eth1, either like ping 193.x.x.x nor like ping www.google.com
Advice, please

The whole story is like this: have a server with 2 NIC cards.
eth0 is used to link to the internal network, eth1 is used to connect to the outside world
Everybody from internal network is accesing outside world using path eth0 -> eth1
eth0 is 192.168.2.1
eth1 is 193.xxx.xxx.xxx
Same server should act as DNS server
can you give an example on how ifcfg-eth0 and ifcfg-eth1 should look like ? I'm stucked :mad:

If you want to play 'let's keep a secret' no one can help you.
Have you disabled NetworkManager and enabled 'network' service ?
I already asked for the relevant info.

ok, NetworkManager disabled (chkconfig NetworkManager off)
still ping 192.168.2.10 works ok (pinging the internal network using eth0)
but pinging any outside IP using eth1 (e.g. 213.165.70.39) or HTTP (www.google.com) address does not

Happy again !! :)
