I would like to know if there is a way to access a computer behind an ICS
computer or router. Let's say I have a computer on the internet at
mydomain.com. It is set up for ICS and behind it are some computers with
addresses 192.168.0.x. If there is no firewall preventing this, could I do
something like \\mydomain.com\192.168.0.123\CDrive, for example? Or if there
is a router, could I ask it to route in any similar way? Thanks...
 
In the ICS adapter's properties you have to go to the Advanced tab, Settings
button, Services tab. Open ports and map to the internal IP of the machine
you want to access. Typically this is done for Web servers, Game servers,
VPN, etc. You do not want to try this for direct file sharing over the
Internet. Use a VPN connection instead. If you have an AD domain, you can
use RRAS NAT on the server OS instead of ICS.

I'm sorry, I shuold have written that I know that it is possible to
confirgure the computer and the router to do this. WHat I was loking for is
if there is any way from the outside to direct something to a specific
computer inside. I know it would be a security issue too. I'm just looking
to see if the protocols make it possible. Let's say for example that I have
a large network behind an ICS and there are several FTP servers. I could
program the router to allow any traffic only from my specific external IP
address. That would help keep it secure. Then if the protocols allowed, I
could freely access any computer inside without having to configure the
router or ICS for specific types of access and be limited by that
configuration. Thanks...
 
As Doug said, you can forward any port for a specific application to the
computer of your choice behind the ICS router. If you want LAN connectivity,
a VPN is your answer. VPNs can be made through an ICS router to any computer
(Windows 2000 / XP Pro) behind it by forwarding port 1723 on the ICS box and
enabling Incoming VPN connections on the ICS client. Then you'll have full
access to any shared resources on any computer on your LAN. This may not be
the most reliable setup, but it'll do in a pinch.

Sorry to keep beating a dead horse, but I really just want to know if it is
possible to specify a computer behind an ICS or router from a URL or other
method without configuring the ICS or router. something like
http://myICS.com//myComputerBehindTheICS/CDrive or
\\123.456.789.321->192.168.0.5\DDrive. I know I can specify a port by doing
http://www.myDomain.com:1234, so I thought something similar might be
possible. I am not looking for an alternative approach. Thanks for the
replies so far and sorry if I didn't explain the question clearly enough.
 
Richard, could you try to be a bit more terse in your answers :-)

No, it isn't possible.

NO, by default that traffic would be blocked by the routers between. Your
best bet would be to forward 3389 to a XP machine behind the firewall and
enable "remote desktop".
