isolating wired and wireless segments

[BoteMan]

I need to set up a small network with both wired and wireless segments. I didn't see anything similar to this here, so I'll throw out the question for review.

I want to have 2 machines with XP isolated (protected) behind a firewall such that they can share each others files and printers as well as accessing the d.s.l. connection, but nothing else can get to them.

I also want to have a "guest" computer access the d.s.l. connection by wire as well as having a wireless a.p. access the d.s.l. connection. This whole segment should not be able to access the l.a.n. segment where the first two machines reside, they should be isolated.

Is this possible with only a Linksys wireless router, such as the BEFW11S4?

If not, will this work:
d.s.l. modem -> BEFW11S4 (wireless and "guest" machine) -> BEFSX41 WAN port (2 isolated machines).

So, I will connect the Ethernet port of my d.s.l. modem to the WAN port of the wireless router to service the guest machine and the wireless machines, then connect a LAN port of the wireless router to the WAN port of the wired router for the 2 office machines, thereby isolating them. Yet, everybody should still have Net access.

Sound reasonable?

I tried working this out with subnetting, but the Linksys can only handle one subnet at a time, so that won't work.


Thanx in advance!

Yes, your dual router solution will work. In fact there is another thread somewhere here by a Hotel owner wanting to give his guests internet acces whilst isolating his own PCs from the guests. The same solution was arrived at.
