i wish to block some port only from a particular IP. using IP tables. ie., I wish to block my Lan users ( only particular Lan Users) reaching particular port for a particular IP.
Say if a external IP ( in internet ) listening to ports 5000,80,8001. I wish to block my Lan users only to block 5000 port only to this IP. So that he can reach other IP listening to port 5000.
How can i do that?
