Avi, most people who want to block usued ports use a firewall. I don't see which disto you are using, both most all of them come with some type of firewall. If you are asking about redirecting ports, (like sending port 80 to a proxy server) then that can be done in iptables. Write back, maybe with more info we can help.

Hi,

the iplimit match is not included in the default kernel sources nor iptables program.
See this :
http://www.netfilter.org/documentati...s-HOWTO-1.html

you've got to use patch-o-matic, you'll find all needed doc on http://www.netfilter.org/documentation

once you'll have patched your kernel, you'll see new options for iptables when building the kernel.
select the one corresponding to iplimit, then your command line should work well, since it seems to me that the syntax is correct and that it really do what you want.

Bye
