Can't Connect Remote Desktop From Outside Network -- DSL Modem?

G

Guest

I apologize if this is a double-post. I just submitted a similar post but I'm
not sure it made it -- I searched for it and it wasn't there.

I have spent the last couple of days trying to set up remote desktop and I'm
wondering if my DSL Modem or DSL provider is preventing me from doing it.

I know I have everything working on me local network because I can do a
remote web-based (and standard) connection to my host from another computer
on my local network. I'm also pretty sure I have the correct settings on my
routers. My router configuration is:

DSL Modem --> VOIP Router --> Wireless Router --> 2 computers

I have the VOIP Router DMZ-ing to the Wireless Router and the proper ports
on the Wireless Router forwarded to the host computer.

I just can't connect to the host computer from outside my network. I try to
connect to the web site http://xx.xx.xxx.xx:xx/tsweb and I get a "can't
connect" error message.

Any thoughts? FYI, my DSL modem is "Microsoft DSL 1000".

Thanks.

You need both TCP Port 80 (IIS) and TCP Port 3389 (Remote Desktop aka RDP)
open/forwarded through any firewall or router the PC you want to connect to
is behind. So, if you go to the http://www.canyouseeme.org site while on
that PC does the test pass? Meaning can you pass both the IIS and RDP port
tests? If not, can you at least pass the RDP port test? Be aware some DSL
modems are also routers and either you need to open/forward the appropriate
ports or configure the modem into a bridge mode, ie. disabling its NAT
function. Check the users manual for help with that.

Also make sure your calling the correct public IP. Note that with most
current consumer grade routers it is *NOT* a valid test to call the PC from
another PC on your local network using the public IP of the modem and/or
router.

Also note that some ISPs block TCP Port 80 incoming because running a web
server (ie. IIS) that is publicly available is a violation of a residential
account terms of service. Check with your ISP about that...

I tried canyousee.org and neither passed the test. I also tried DMZ-ing both
routers and it still didn't pass the test. I previously opened the ports on
the host computer's firewall and I was able to connect with another computer
on the local network, so I assume that means the firewall is configured
correctly.

I'm going to try plugging the host computer directly in to the DSL modem.
Will that at least isolate the problem?

Re: calling the computer from a local network computer, I had someone else
try from across the country and they got the same error message.

OK, I tried connecting the host computer directly to the DSL Modem and
canyousee.org still couldn't see either port.

It sounds to me like that DSL modem is also a router. With the computer
connected directly to the router what IP is reported if you go to "Start ->
Run" and type cmd at the command window, then type ipconfig at the command
prompt? Is is a 10.X.X.X or 172.16.X.X or a 192.168.X.X address? If its one
of those IP ranges then you need to find a way to put the DSL modem, which
is also a NAT router, into a bridge or pass through mode of operation, ie.
the built-in NAT is disabled. Check the users manual for help with that or
check with your ISP.

Thanks for the reply. I Googled the DSL modem (MSN DSL 1000) and it appears
that's the problem. I found a lot of posts looking for solutions for problems
similar to mine -- playing games, FTP, etc. I'm going to try getting a used
modem on Craigs List and see if that does the trick.

Remember that in order to use the web based Remote Desktop method you need
both TCP Port 80 (IIS) and TCP Port 3389 (RDP) forwarded/opened on any
firewall/router between the public internet and the network...

Some ISPs block TCP Port 80 incoming because running a web server violates
the terms of service for residential accounts.
