Setting up an internal linksys wrt45g and external linksys befsr81

Hi there,
i have a windows 2003 server with dual nics. i am trying to set up a wirless
wrt54g on the internal subnet and a linksys befsr81 on the external nic. Is
there a way to set up the internal user to access the internet with nat or
should i use forwarding on the internal router.

thanks

Which router is currently offering NAT? You listed 3 of them including the
2003 server. Is this multihomed server a DC?

If I understand your infrastructure, tt seems like:

Internet -> BEFSR81 -> 2003 Server -> WRT54G

Is that correct?

If so, why not just use the wireless WRT54G as you incoming router instead
of the BEFSR81 and remove or disable one of the NICs on the server?

Thank you for answering. This is a sandbox environment for testing purposes.
I have a dual nics on the 2003 server. One router (linksys BEFSR81)is on the
external nic configured for internet access. The other router(linksys
wrt54g) is on the internal nic for internal workstations and internal
wireless access. I want to keep the internal network as far away as possible
from intrusion from the outside. Is this possible? I have heard that its not
a good idea to have a multihommed environment on windows 2003 server. Why
??...I would like my server to do NAT for both internal and external clients.

Actually multihomed DCs is NOT recommended because it's effect on AD
registration in DNS.

Honestly, on the same token, I would not use a Windows machine for a router
anyway. It's Windows. Costly. Routers are much cheaper and are dedicated.
Same with NAT devices, they are essentially specialized routers that route
AND translate headers at Layer 4 of the OSI.

You can do that. If you want to route internally, you need to understand how
routing works. NAT translates, where routers purely send the packet on with
translating anything. If you have three segemented networks, it's advised
the edge router is your NAT device and the internal routers are just
routing. To allow access from the internal segments, you need to configure
static routes. Check this example to see what I mean and apply it to your
scenario.
