Subnet & RDP

We can only RDP into other's sets if they are behind the same router as us.. (or the same network)

Now does this mean I could RDP into your computer if we are behind the same router but on different subnets? (or does being on a different subnet qualify as being on a seperate network?)

We have over 90 subnets at work, behind different routers, and I can RDP across into any of them except 1 because that one has 3389 blocked via a Cisco PIX.

Okay, then how do you RDP into another set if it's behind NAT?
The private IP technically doesn't exist, since it's hidden behind NAT. so how would you get into it?

with the private ip address... assuming you have routing between the sites. ??? pretty straight forward.

What do you mean? How is that straight forward? IF these routers are using NAT, then how would that work?

Please look at my attachment. It should make my question very clear.

Because internal routing tables exist between the sites. It isnt routing outside the giant VLAN and asking the public IP where the internal IP is.

That's exactly what it's doing; he even drew a picture.

You'd use port forwarding or establish an internal connection via a VPN.

Don't lie Dynamik. You'd use a chip implant in the brain to think what you want it to do and it then just works.

Apparently I need to look into a CCNA or something.

BTW, Thread Stalkers are the worst kind of annoying.

We've already established what happens when I try that method. I really don't think that's the solution he's looking for...

Wait a second so you have the same subnet on 2 different networks ?
i am assuming there is no VPN if there is a VPN how are you doing that ? QinQ ? some dodgy VPN tech ?
if you have a VPN and there are different IP ranges at different sites then you can RDP to the IP address no problem.
If you are on 2 different sites and for some reason are not connected VIA VPN you would use NAT/PAT from the outside address of the Target site to what ever you want internaly.
or you would bounce off a single server on that site or however many Servers you have real world IP's for and 1 to 1 nating's.

you can have 1 Real IP address on the out side and have say port
40001, 40002, 40003, nat'ed to
192.168.10.1:3389
192.168.10.2:3389
192.168.10.3:3389

all this would mean is when you rdp not only do you enter the external IP you also enter the port like so
68.105.10.42:40001 = 192.168.10.1

You could probably do with reading up on NAT as it is what makes the world gor round.
