I am going to assume you're talking about an 11S4 router.
You got FW's on the machines, you may need to open ports 137, 138, 139,
and (445 NT based machines) based on the DHCP IP's that can be issued by
the router.
Or, it could be that you need to use the NIC protcol NWlink IPX/SPX
NETBios compatible on all machines so that they can communicate with each
other and, maybe, in particular that ME machine. And if you do decide to
switch to NWLink, uninstall the other protocol first, otherwise, you may
hose the TCP/IP Stack on the machine.
The cheap NAT routers in this class do not have a FW and can be easily
defeated by a determined attacker. A router with a FW blocks inbound and
outbound traffic by default. At most, the router has NAT and SPI --
firewall like but is not a FW.

The protection of the machine and the network starts with the O/S. I
cannot say much about ME, other than, get rid of it.

Windows is Windows no matter what O/S and don't think that someone will
not possibly come at your set-up, because it's not a big corporate set-
up. They have got to practice on someone before going for bigger game.

I suggest you install a host based FW on the machines behind the router
for a layered protection approach.
And make sure you address the DCOM RPC *worm* issue on the XP machines,
which as been in the news as of late, if you have not already done so.
And the worm can attack Win 9'x and ME, if somehow, it got installed on
the machine.

This is most likely more than you want to know.
