Hi Vairavan, The main highlight here is that you are using 20.xxx.xxx.xxx as your private network, this is not compliant with RFC1918 and would cause connectivity issues to public address in this subnet.
Do you own a range of public IP address you wish to allocate to VMs? If so, this will effect the way you setup your Cloudstack Networking. If not, and you are looking for a simple setup, I would recommend the following: Management: eth0: your.public.ip.addr eth1: 10.10.0.1/24 (Private Interface) Agent: eth0: 10.10.0.2/24 If you wish to stick to your current setup (which I would advise against), can your agent ping your 20.1.1.1?
