    hi everyone,

    I'm new to this Linux thing & I tried to setup my old computer with Redhat 5.10 as a router. I already read all kinds of stuff on the internet but I still don't know how to open port to a server. Could someone tell me what I'm doing wrong?

    [root@router ~]# iptables -nvL

    If you're running RHEL 5.10, you have paid support - use it.
