WAN static IPs to LAN static IPs routing question

I have 5 static IPs from my ISP. 4 will be used. I want one to go to my LAN for general use as 3 others need to route to specific computers which also are in the 192.168.1.xxx range. The 3 boxes all use SSH, SFTP and HTTP so I need each WAN IP to route through it's own LAN IP. I have a Linksys BEFSR41 for my general router and 3 BEFSR11s for individual statics. All computers need to be on the same 192.168.1.xxx subnet for printing access. How do I do this? This was my thinking but I keep getting errors: Cable modem SMS8013 with 4 LAN ports acting as gateway WAN gateway address is AAA.BBB.CCC.214 with 5 statics being 209-213 LAN address for SMS is AAA.BBB.CCC.208 - chosen so it's in same subnet BEFSR41 WAN is AAA.BBB.CCC.209 LAN is no DHCH BEFSR11 (a) WAN is AAA.BBB.CCC.210 LAN is (linux server) BEFSR11 (b) WAN is AAA.BBB.CCC.211 LAN is (another linux server) BEFSR11 (c) WAN is AAA.BBB.CCC.212 LAN is (SCO server) D-Link wifi access point with DHCP enabled LAN is DHCP range Printers are in range All BEFSR LAN ports are connected to a switch as are all computers and printers.

I have tried port forwarding each BESFR11 on required ports to specific LAN IPs. Should I use static routing instead?

I think these two are the same thing.. .208 is your network address, and can't be used as a host address, your broadcast address is .215, and .209 - .214 are valid host addresses. your cable modem is acting as the gateway, and is on .214, you have .209 - .213 to play with. This is assuming that you are using the netmask on the WAN side, and that your network assignment is AAA.BBB.CCC.208/29. You probably want to point the default gateway on your unix boxes towards the appropriate router.

Your call.. depends on how much you want to expose your unix boxes.

I have a setup at home with 4 static's from my DSL provider, and a single FreeBSD box acting as router/firewall for everything. 1 address used for the router itself, and 3 NATed to 3 individual nets inside, with routing between internal nets.

.80 = router external .81 = net_1 external / internal .82 = net_2 external / internal .83 = net_3 external / internal

The internal nets can talk to each other, subject to ACL's on the router, and they can all talk to the outside world. currently the only access from outside->inside is via the router itself.
