I have a scenario: i will have to protect my network from unsolicited access from my DMZ machine, configure node-A to allow new connections on port 1915/tcp from hosts (obtained by 'getent hosts node-B') but disallow any other access from or to node-B.

I am unable to find any port details by 'getent hosts node-B', how to perform this using iptables?

  • This need more clarification, I suggest you focus what you want to achieve and not about what you did until now to try and make it to work. – Rabin Jan 14 at 7:15
