hey friends, I am using FC3 on 2 computers and both the computers having 2 Lan Cards. The network id of my company is <a href="http://192.168.1.0/24.I">192.168.1.0/24.I</a> have given 192.168.1.67(on first computer) and 192.168.1.68(on 2nd Computer) .The other lan card on both the machines are having network id <a href="http://10.0.0.0/24">10.0.0.0/24</a> with ipaddress 10.0.0.1(on first computer) and 10.0.0.2(on second comptuer).I am trying to build clustering with Heartbeat that is why I required 2 Lan cards on each machine. Now the problem I am facing is that I am not able to browse the internet from these 2 pcs.The SELinux and Firewall is disabled on both these pcs.The configuration files for both Lan Card is First Lan Card on First Computer # Marvell Technology Group Ltd.: Unknown device 4361 DEVICE=eth0 ONBOOT=yes BOOTPROTO=static IPADDR=<a href="http://192.168.1.67">192.168.1.67</a> NETMASK=<a href="http://255.255.255.0">255.255.255.0</a> GATEWAY=<a href="http://192.168.1.1">192.168.1.1</a> HWADDR=00:11:11:65:76:76 TYPE=Ethernet 2nd Card Lan on First Computer # Realtek Semiconductor Co., Ltd.

I am able to ping <a href="http://10.0.0.1">10.0.0.1</a> and <a href="http://192.168.1.0">192.168.1.0</a> network from both the machines but not to any machine on the internet (for ex ping <a href="http://www.google.com">www.google.com</a>). Even If I disable the eth1 on both the pcs still I am not able to browse the internet.If I give the command "neat" I can see eth1 is the first entry and eth0 is the second entry. Please help me in solving the problem. Thanks & Regards Ankush Grover
