compa, compb and compc.I have set up Remote Desktop and can use RDC to control any of the PC's from any other
as long as I enter their pcname or local IP address (eg. 192.168.0.xxx) in the RDC box.
That works fine.
I have a DDNS account that gives me a fixed domain DSN (eg. *.network.dyns.cx) so that I can connect remotely
to any of the PC's by entering the internet IP address (rather than a local one) in an RDC connection box.
In my D-Link Virtual Server (VS) setup I set compa to port 3389 (the "official" RDC port for Windows). I set up
compb to 3388 and compc to 3387.
If I use RDC to remotely connect to compa and thus enter compa.network.dyns.cx in an RDC box, I connect, as expected,
to compa. That's great! But if I enter compb.network.dyns.cx, I still connect to compa.
if I enter compc.network.dyns.cx, I still connect to compa.
I cannot enter *.network.dyns.cx as an IP address. That's invalid. I have to replace the * with a valid
computer name that I have set up in the D-link VS list. As mentioned above, if I use the compa computer name, that
is accepted and I'm "ported" by 3389 to compa. What's clear is that if I use the other computer names as the prefix,
the D-Link does see them as valid computer names but the port chosen is not the one in the VS list. 3389 seems to
override the port number in the list. Of note, when I do use compb.network.dyns.cx, but get connected instead to compa,
the small box at the top of the RDC screen erroneously says I'm connected to compb.network.dyns.cx.
I read the Microsoft Article 306759 that describes how to change the listening port for Remote Desktop.
OK, I figured I would change the listening port on compb to 3388 and did that via Regedit, as the article described.
I also entered a new REMOTE DESKTOP entry in the Windows Firewall exceptions and assigned it 3388. Of interest, I
first tried to merely edit the official REMOTE DESKTOP entry in the Firewall but found that "edit" would not change the
port number from 3389. It appears to be "hard coded". Anyway, I then entered compb.network.dyns.cx:3388 as outlined
in Article 304304 but the connection was denied. Removing the :3388 suffix only put me back into the pickle of connecting
again to compa. 3389 rules again!
So, why does Microsoft tell us how to change the RDC Port number but Windows won't pay attention to the change? I was hoping that I
could set 3388 to compb and 3387 to compc.
I'd love some help.
However, please don't bother telling me about the workaround, namely that one can daisy-chain RDC requests. Indeed, that's
a nice workaround. For those who don't quite understand, the procedure is to RDC to the one computer, say compa that will work with
an Internet IP. Then, with RDC controlling compa, issue an RDC using the local computername compc (or it's 192.168.0.xxx IP address).
You now can remotely control compb.
Thanks for any help,
PS. I've used phony computer names above for security reasons.
