How can I block ports from outside and allow it for internal communications?

Jump to solution

Hello Guys,

One of our vulnerability scanner gave the following ports as vulnerable, so we want those ports to be blocked from outside and to be allowed from the inside for inside communications.

These are the ports


264/tcp - fw1_generic.
500/udp - ikev1.
18231/tcp

18264/tcp - cp_ica

how can i do this?

Thanks
