Debugged with Ankit and found that the issue was due to configuring port 55 for ICMP which is not allowed. Once the port 0 was configured it started working fine. There is also a UI issue which allows configuring arbitrary port numbers for ICMP. The UI issue bug will be filed separately with UI team.
