    What are you using the router for?

    I need to setup some NAT rules that allow something like this:

    internal IP start, internal IP end, global IP, comment
    192.168.1.1, 192.168.1.1, 123.123.123.1, server1
    192.168.1.2, 192.168.1.2, 123.123.123.2, server2
    192.168.1.3:1234, 192.168.1.3:1234, 123.123.123.3:1234, server3
    192.168.1.4, 192.168.1.9, 123.123.123.4, external network
    192.168.1.10, 192.168.1.254, 123.123.123.5, internal network
