Accessing a Computer Outside of my MN-700

Here's my configuration first. Start at the cable
modem. It is hooked into a switch. Two desktops
(located in the same room) are tied directly to the
switch. The MN-700 (as a router) is located in another
part of the house and is cabled (via ethernet) back to
the switch. I have two laptops using the MN-700 (both
via wireless). If I use the MN-700 as an access point I
can see all computers from all computers. If I use the
MN-700 as a router, communications is stopped between the
laptops and the two desktops.

I can't move the MN-700 as I won't get reception if it's
in the back room where the cable modem is located. I
can't move the cable modem either.

So...is there a way for File and Printer Sharing to pass
through the router? Is a Virtual DMZ part of the
answer. If so, how is it set up and how does it work?

Thanks!!

It's likely that your ISP is blocking the Windows File/Print sharing ports
for security reasons , so your idea may be moot point (not that it could be
recommended anyways)...

Otherwise, you'd have to forward the ports that Windows File/Print sharing
uses, or put the computer in the DMZ.

Thanks. How do I "forward ports and place a computer in
the DMZ?" I have file and print sharing implemented via
IPX/SPX (if that matters).

p.s. I don't believe the ISP has anything to do with the
problem. Remember, when the MN-700 is an Access Point,
everything is fine and all four computers are inside the
cable modem.

IPX makes a difference...

If the MN700 acts as a router, then basically, you have two distinct
networks.
The MN700 routes TCP/IP ONLY.

Virtual DMZ won't help with non-TCP/IP protocols.

The router is blocking the NetBIOS messages from flowing.
The firewall blocks them from coming into the LAN part of
the MN700, and NAT blocks them from going up to the
switch. Turning the MN700 into a switch (bridge mode)
disables NAT and firewall, and that's the reason you can
see the computers in access mode.

Getting the MN700 into bridge mode is probably the
easiest solution (why do you need it in router mode?).
Bridge mode turns off NAT, so all computers stay in the
*same* LAN.

The DMZ won't work, since it opens all ports for a
*single* computer and you must specify the IP in advance.

Another approach is to use a VPN. A VPN can connect
computers on different networks, so it let you get
accross the two LANs (including NAT and the firewall). XP
has built-in support for VPN servers (PTPP is supported
on XP Home). Assign static IP's to the desktops, install
the VPN server using the network wizard, and then set a
VPN client on the laptops, again using the network
wizard. For PTPP you need to open port 1723 on the MN700,
and that should do.

Is the "switch" a router/switch combination or is it pure a switch? Do the
two desktops get their IP address from the switch or from your ISP? If your
switch is also a router, as is very often the case if you bought it for
sharing your broadband connection and your cable modem connects directly to
it rather than going through one of your desktops first, use the MN-700 in
Access Point mode (which you said worked) and be done with it. In Access
Point mode your switch will hand out IP addresses to all your computers and
they should all see each other and the internet just fine.
