In order to access (using remote desktop/remote assistance in Windows XP) a
_single_ computer behind a router (like a netgear/d-link/linksys home router
you would get at Circuit City, Best Buy, Wal~Mart, etc...) you need only to
forward port 3389 on the router to the local IP of the machine you want to
remotely connect to *and* open up port 3389 through whatever software
firewall you utilize on said computer *and* have Remote Desktop turned on
(default settings) on the machine *and* have accounts on that machine with
passwords that are members (directly or by inheritance) of the "Remote
Desktop Users" group.
This assumes your modem is purely a modem - not a NAT device in its own
right (or those features have been disabled.)

Not for a single machine - see above.

One method of accessing several machines behind a single router is to change
the listening port for Remote Desktop on the computers behind said router
and then forward the appropriate port(s) to the approproate machine(s) on
the router itself... Then when using the remote desktop client -
router-ip
ort is entered instead of just router-ip (specifying the port to
specify the machine.) There *are* other methods.

Somehow I feel you are making this more complicated than it should be.

1) Leave one machine that is behind the router untouched - at least as far
as the port that is used to listen for remote desktop requests (3389.)
Assign this machine a static IP.
2) On each of the other machines, change the port - for example, let's say
you have four total machines... Leaving one at 3389, change the listening
port on the next one to 3390, the next to 3391 and the last to 3392. Assign
each these other machines static IPs.
3) On your router, create forwards for each port (3389, 3390, 3391, 3392) to
each corresponding static IP for the machines.
4) Ensure Remote Desktop is enabled on each of the machines.
5) Ensure you have valid username/passwords for each of the machines.
6) Ensure the software firewalls of each of the machines are allowing the
repective port/application through the firewall (Remote Desktop.)
7) Make sure the user you will be utilizing to remote to the machines is a
member of the Remote Desktop Users group (or is a member of the
administrators group - which makes them a member of the other group
automatically.)
If you have all of those done for each of the machines on your private
network, then when you are away you merely need to know the IP address for
the router and which machine you wish to connect to (and the
username/password of course.) When running the Remote Desktop Client - for
all of the machines that are *not* using port 3389 (the default one) - you
will put the ip-address
ort... The PUBLIC IP Address of the router, colon,
the port of the machine you wish to connect to.
