[newbie] Firewall

[Jon Greisz]

I bought Mandrake 7.1 and installed it this weekend.  I'm trying to setup a firewall between my network and the internet.   I've got the following:     Server with Mandrake 7.1   NIC - configured for internal network   NIC - configured for internet, connected to our T1   I've used 192.168.1.0/24 as my internal subnets.  I've got 64 external IP's.  I need to allow access to several of my client machines on the internal network using a specific port from the internet.  All of my clients need access to the internet.   What is the easiest way to get a firewall going.    Thanks,   Jon Greisz
