Hi Satish, Are you using the ‘router-gateway-set’ command? Or the ‘router-interface-add’ command? Based on the behavior you described, it sounds like the latter.
If you need to attach the router to the external network, use the ‘router-gateway-set’ command. An IP should be allocated from the pool. If you need to attach the router to an internal network to serve as the gateway for said network, use the ‘router-interface-add’ command.
