Too complicated?

Hi,

I tried already to search for forums with my problem but couldn't find answer.

Setup:
ISP with 5 dynamic IP
2 x Xbox 360 (.11N and .11G)
2 x Eeepc laptop (.11N and .11N)
1 x Home Theatre PC (.11N)

Now I have 1 ADSL modem + Buffalo AP in router mode and every DHCP client gets IP address from ISP. For some reason my 2 xbox's doesn't work same time at xbox live if they are under NAT+DHCP. Tried UPnP but it got even worse.

What I am searching:
- All-in-1 box which can get:
+ 2x Dynamic IP for xbox 360's (83.xxx.xxx.xxx and 83.xxx.xxx.xxx for example)
+ 1x Dynamic IP for eeepc's and htpc and guests ( NAT + DHCP + Firewall for these guys ofc)

Doesn't sound bad but haven't found a single box which could do it Too messy? It's ok to have multiple boxes or add one box to my current setup.

I found http://www.sonictest.eu/index.php?83,routerboard-750 but when I red the manual I almost passed out

Thanks for the answers already

Probably not gonna find such in a modem/router combo, just get an AP or router in AP mode with at least 2 lan ports, to put in between the router and modem.
