Remote Desktop cant connect

[Guest]

Hello,

Yesterday I wanted to setup my laptop to connect to my home computer where
ever I are. I looked through this discussion forum, and I found some things I
should do.

I setuped my router 3com 3CRWE554G72 as it said at
http://www.portforward.com/routers.htm (Post forwarding).

I used Custom Name : Remote Desktop and port 3389.

After this I could still not ping my router.

Then I found out that I had to open my modem Thomson Speedtouch 510. Because
the Router has a firewall, I just shut the firewall of on the modem.

I went to controlpanel/windows firewall and laid in exception Remote
Desktop. Under advanced/network connection settings I also added
RemoteDesktop as a serivice there.

Still I can't connect to my homepc via Remote Desktop? What can I do?

The Speedtouch 510 is itself a Modem/Router. It seems that you have a
double layer of routing and NAT translation, one in the Speedtouch, and one
in the 3Com. It isn't clear to me why you have the 3Com, as the Speedtouch
could do it all.

If you stick with your present double router setup, you will need to
port-forward TCP port 3389 in both routers.

In the Speedtouch, you will need to forward TCP port 3389 to the IP address
that the Speedtouch assigns to the WAN port of the 3Com router (this might
be tricky, as it might be subject to change under DHCP).

In the 3Com, you will need to forward TCP port 3389 to the IP address of
your home PC.

When you attempt to connect from outside, you will need to call the WAN IP
address of the Speedtouch (not the IP address of the 3Com, and not the IP
address of your home PC).

The reason why I have both the Thomson Modem/router and the 3com
router(wireless), is that I used this 3com router, to connect with my laptop
when I had another internet distributor. When I got this new internet
distributor, we got this thomson Modem/Router for free. Didn't want to buy
new hub/wireless gateway

Thanks for the good answer, I will try this out. It's not always easy for a
noob... you know

Why not use the 3Com device as a wireless access point only then. That is what I did, at one time,
with my Buffalo WBR-G54. In my case I used a Linksys BEFSR41 router as a front-end to my home LAN so
I did not need to use both as routers. Turn off the 3Com built-in DHCP server and give it a static
IP on the LAN. Check your users manual for instructions on how to do that...
