linux routing inside a network segment
I have only found documentation for masquerading using one
real IP address and a private network type 192.168.x.x
I did that and it worked, the problem is that I need real addresses,
and my linux box is between the gateway and all my network.
I configured the routing table with the command ip and I can
access the gateway and all the nodes on my network, but it
just doesn't forward.
What am I doing wrong? I someone could just help me, it would
save my job.

sounds like quite the job you have there. Are you using standard port forwarding for some addresses and masquerading for others? For instance:
Comp1 = 188.8.131.52
Comp2 = 184.108.40.206
Comp3 = 220.127.116.11
Comp[4-9] = 18.104.22.168
Comp[10-99] = 22.214.171.124
If you are then you just have to set up different rules in the /etc/sysconfig/iptables (or ipchains depending) that just sort on IP addresses. Like (give me a break this is from memory):
-A -s 0/0 -d 126.96.36.199/255 -j FORWARD_1
-A -s 0/0 -d 188.8.131.52/255 -j MASQUERADE_1
where FORWARD_1 and MASQUERADE_1 are other chains you set up to send it to certain areas of your network.I respectfully decline the invitation to join your delusion.
