Apologies if this is a repeated post =)

I'm having problems with accessing my PC that is connected to the
AirPort Express. My setup(s) are as follows:

Setup 1 (OK)
- PC is wirelessly connected to AirPort Express
- Mac is also wirelessly connected to AirPort Express
- Mac is able to use RDC to connect to the PC when 'PC IP address',
'User name' and 'password' are inputted

Setup 2 (NOT OK)
- PC is wireless connected to AirPort Express
- Mac is connected to the Internet
- Mac is unable to use RDC to connect to the PC when 'PC IP address',
'User name' and 'password' are inputted.

Note:

1) AirPort Express is setup as a Network to 'Distribute IP addresses'
so that the AirPort client computers are 'Sharing a single IP address
(using DHCP and NAT)

2) AirPort Express is setup to access the Internet 'Connecting Using:
PPP over Ethernet (PPPoE)'.

What am I doing wrong? Please help, thank you!

Can you please verify the numbers in your IP addresses for me? Are they
in the form of

192.168.xxx.xxx or 10.xxx.xxx.xxx

or do your IP addresses begin with

169.254.xxx.xxx?

The 169.254.xxx.xxx addresses are self-assigned, meaning that the
computer is unable to locate a device on the network handing out IP
addresses.

My IP addresses start with 10.0.1.1 - 10.0.x.x

In your Internet-connected instance--if the Mac is in a different location
from the PC and the Airport:

1) You must use the public IP address acquired by the Airport as the target
address.
2) The Airport must be configured to route unsolicited inbound traffic on
TCP/IP port 3389 to the private (10.0.xx) address of the PC.

Dyndns is the usual method for tracking the public IP address of the private
network behind the router--but you can also either look at status screens on
the router, or go to whatismyip.com on the PC.  With PPPoE, you can't be
certain how long a particular address will be in use, however--so setting up
Dyndns is something to do early on.

Your addresses sound fine and so long as they both begin with the first
three numbers 10.0.1... then your machines are capable of communicating.

I'm confused by the difference you make when in Setup 1 the Mac is
wirelessly connected to the Airport Express and in Setup 2 the Mac is
connected to the Internet.  Can you explain the difference? Are you
attempting to connect to your Windows PC while it's on the inside of
your network and your Mac is on the outside of your network?

Hihi!

Yes, u're correct. The PC is within my home network.. whereas my Mac..
it's outside my home network, for example at work.

Then you're looking for instructions like these
<http://theillustratednetwork.mvps.org/RemoteDesktop/RemoteDesktopSetupan
dTroubleshooting.html>. The page looks daunting at first, but it's
really very thorough in what it's telling you to do.

For RDC to work, both computers must be on the same network to
communicate. If they're not on the same network then you must configure
your router to "port forward" port 3389. This means you'll tell your
router to take all incoming RDC traffic and direct it to your Windows
machine on the inside of your network.

Hope this helps! bill

Just tried it from your reply. Works for me. Not sure why you're unable
to access it.

The link is fine, but it has probably been wrapped around in the OPs
newsreader, looking something like this:

> <http://theillustratednetwork.mvps.org/RemoteDesktop/RemoteDes
> ktopSetupandTroubleshooting.html>.

ttling, you have to put the different parts of the URL together again
in your web browser's address field. You cannot just click on the
first line of the link, because the URL is wrapped around over
several lines.
