ipchains....opening tcp and udp specific ports with Mandrake 7 kernel 2.2.14

[Marc]

Hello all,
Need some help opening specific tcp udp ports.  I've read the ipchains how
to and the firewall how to , but I guess I just can't quite comprehend what
I need to do to open specific ports so some programs on my winblows boxes
can reach the net.
One of the ports that I need open is 27960 udp and tcp.
According to the web sight of one of these software companies you have to
add these lines to open the proper ports for their software to
work......well these are old and apparently dont work with the 2.2
kernel...here they are:
ipmasqadm autofw -A -v -r udp 2300 2400 -h www.xxx.yyy.zzz (ip of box behind
firewall)
ipmasqadm autofw -A -v -r tcp 2300 2400 -h .........
ipmasqadm autow -A -v -r tcp 47624 47624 -h .......
ipmasqadm autow -A -v -r udp 47624 47624 -h .....
ipmasqadm autow -A -v -r udp 28800 28900 -h .......
I tried this and it did not work  .....I need to know the ipchains
equivalent of these commands????  Please help!! If you need any other info
let me know.

Thanks
Marc
