Null routing to one specific IP/Port

astroboy5714 · 03-12-2004, 03:38 AM

What is the command or extension to null route an IP to block them from accessing only a specific IP and port? I want to allow them to access everything on the system except for one port on one IP. I can block them from accessing the server entirely, and I figure there must be an extension I can put on the command line to do this.

Thanks in advance.

u can block with "iptables"

if u explain your network and tell me what do u want to do exactly, i can help u more.
