On GRID VCA, I cannot ping anything from DOM0 but inbound pings are OK.

SSH to GRIP Appliance IP, login,  and run the command 'grep SNAT /etc/sysconfig/iptables'

The output line will look like the following and the ip address at the end of the output should be your GRID Appliance static IP address: 

-A POSTROUTING -o eth0 ! -p vrrp -j SNAT --to-source 10.20.187.51

If the IP address at the end of the output is not your GRID Appliance IP address, edit the SNAT line in /etc/sysconfig/iptables to use your GRID Appliance IP address.

Then run this command:  /etc/init.d/iptables restart
