But he already has 5 public addresses, one per computer, since the start. It is in the OP mail.
This is from the original post:

. . .
My network is split into 2 halves, 192.168.10.0/25 is my "internal" zone, and 192.168.10.128/25 is my "dmz" zone . . .
Those both look like internal non-ISP address blocks to me.
You did not read the complete email, which is complicated to understand: «My "external" zone NIC has been assigned 5 different public IP4 addresses, all statically assigned by using the YaST2->Network Card Setup to assign one of these public IP4 addresses to the NIC card itself, and the other 4 public IP4 addresses are assigned to this same "external" NIC card as additional addresses for that "external" NIC card.» «My network is split into 2 halves, 192.168.10.0/25 is my "internal" zone, and 192.168.10.128/25 is my "dmz" zone. Except for "quasar" each computer has 2 NIC's, one for each of my zones. Addresses and default routes are assigned by a dhcpd server, and that much is working fine (AFAIK) at the moment.» His plan was, more or less, to translate packets on the external IPs to packets on one of the internal LANs «What I want to accomplish is to set up the routing so that any incoming traffic to one of these external additional IP4 addresses, on a port, gets routed from "quasar" to one of my other computers on the DMZ side of my network on the same port number. So for example, lets say there is incoming traffic whose destination is 111.111.111.112:10. I want this to be routed/forwarded to my internal computer called "Nova" at it's DMZ address of say 192.168.10.210:10 and I don't want to specify a rule for each and every port number specifically. Different computers will have different services listening on different ports.» This is an over complication, instead of simply assigning one external address to each computer and routing that, directly. Or switching. -- Cheers / Saludos, Carlos E. R. (from 15.4 x86_64 at Telcontar)
