Hi All,<br><br>I am using kernel version "kernel-ml-PAE-2.6.39-4.1.el5.<div id=":1v">elrepo.i686.rpm".
My machine has two network interfaces eth0 and eth1. I configured IP on
both the interfaces. Below is the snippet.<br><br>eth0 Link encap:Ethernet HWaddr 00:15:17:61:D2:16<br>

<br>I configured default gateway in eth0. Below is the snippet.<br><br>[root@ACS172 ~]# route -A inet -n<br>

0.0.0.0 10.77.247.161 0.0.0.0 UG 0 0 0 eth0<br><br>Issue:<br><br>The
issue is IP configured in eth1(10.77.243.154) is not pinging from other
subnets(other than 10.77.243 network in my case). I captured TCP dump
and could see ICMP request reaches the eth1 but ICMP response is not
sent back.<br>
<br>Please let me know anyone faced this issue and how to resolve it. I
am blocked because of this issue, any help would be really helpful.<br><br>Thanks,<br>Prem.</div>
