Yes.It worked.

In addition,we added this line as well.

1) We added this line in vpxa.cfg "<preserveServerIp>true</preserveServerIp>".After configuring this line,VC Public IP address will not be changed.

2) We added the NAT public IP address in vpxa.cfg "<serverIp>212.*.*.*</serverIp>"

3) And we created a new vmkernel port group(with new vSwitch and no VLAN,no nic binding needed) with ESXi NAT public IP address.

it worked well and thanks much for the inputs.

Thanks,
