Hi,
I have two layer of firewall , front end is checkpoint and back end is cisco fwsm , when i do nmap port sacn from external network to inside any host I can see port 1720 is as always open , but there is no service running in server with port 1720, I know port 1720 is H.323 call setup protocol used by multimedia collaborative apps such as NetMeeting to establish and control a collaborative session.
could anyone help me on this ?
