Redhat9 router...

I have succesfully setup a linux router by using 2 NIC and share the internet between them...all my pc client are gateway to my 2nd NIC where the 1st NIC is directly to Internet Connection..

2nd NIC
: ip - 192.168.168.1
netmask - 255.255.255.0

ip client will be - 192.168.168.X
netmask - 255.255.255.0
gateway - 192.168.168.1

the first question is how to block the internet connection from my linux to the specific client in my network such as his ip is 192.168.168.10

the second question is how to block mirc port, my client always wasting time to chit chat while working...so I want to block the mirc port which will blocked the connection to mirc server...all this i want to do from linux..

thanks

Just block the port that mirc is using in the firewall its usaly port 6667 or 6666 i think but its possible to work this around anyway, so if you have good employees they will find a way to chat anyway :)

The dont alow internet have the same solution use a firewall to block the specific ip to connect trough the server what system are you using and what is your config for the internet sharing ?
