Cannot access desktop through XP Remote Desktop

Hi,

I have a Connexant ADSL USB Modem, I have opened up the 3389 port for the P.C. (10.0.0.8)

When I try to connect to the office computer - using http://x.x.x.x./tsweb

It says

Server Error: 501 Not Implemented
________________________________________
No RPM for this combination of URL and method
________________________________________

/tsweb



Any ideas

Thanks

Hi Secureconcepts,

Have you opened Port 80 also (to be able to get to the connection page?)
Do you get a connection when you use the RDP client from:
http://www.microsoft.com/downloads/details.aspx?FamilyID=80111f21-d48d-426e-96c2-08aa2bd23a49&DisplayLang=en

Btw, Server Error: 501 Not Implemented is a Mozilla error.
You can't use Mozilla or Firefox to connect with the tsweb function, you need to use IE as you need to install an ActiveX component for this to work.

Also, you are using the WAN IP address instead of the internal 10.0.0.8 addres?

When I use Internet Explorer - across the top it says http 501 not implemented

When I telnet 0.0.0.0:3389 - IT SAYS CANNOT OPEN CONNECTION ON PORT 23 - connection failed

0.0.0.0 is the WAN address

I though I need to connect throughj the WAN address

Thanks

did you forward the port to 10.0.0.8
just opening with out an ip won't work

LucFCommented:
Strange but ok...
Let's forget about the ActiveX component at the moment and just try using the Remote Desktop Client. That'll make troubleshooting a bit easier.

Are there any firewalls installed anywhere? (both the winXP build-in one and any others?)
Or, maybe the computer you're using at the moment is filtered by a proxy or such?

OK, are you inside the LAN now? (on the same local network as the host?) If so, then you must use the local ip (10.0.0.8)

Hi

I am on the same Lan as the host,

I thought I can connect through http://0.0.0.0/tsweb as if I was on the internet anywhere


I have connected through my phone - GPRS and get the same problem.

Any more ideas

Thanks

I'm seeing I'm accessing the router instead of your computer.
For this implementation to work, you also have to forward port 80 to this computer.

Btw, for your own security. Get rid of the remote administration function of your modem.

When you say forward port 80 to this computer

Do you mean on the Virtual server page


forward to my Laptop (Client i am trying to connect with)

My desktop - (the host I am trying to connect to - done)

The password is defauklt at the moment - can you logon

U/N - admin

Wierd, it worked before, now I'm getting "Page cannot be displayed" as in, you turned off the remote configuration of your modem.
But please, change the password now. These pages are indexed by google and you surely wouldn't like anyone else on your system.
(in fact, it might be best if you ask http:/Community_Support/ to remove your WAN IP from this question)

Yes, you should forward port 3389 in the "Virtual server" page to setup port forwarding for Remote Desktop
You should also forward port 80 there in case you prefer to use the web-based RD client.

So, the rules posted at http:#13391770 are indeed the correct ones.
One thing I'm wondering about is that you have a USB modem?
How are you connected to it as you say you have more than one computer on the internal network... Does your modem also have a UTP connector which you can connect this computer on which you want to run RD?

I have one ADSL Router (Connection from ADSL router to access point is through Ethernet Cable)

Connected to WAP54G Linksys Wireless Access point, all client devices are connected to the access point


For the desktop (10.0.0.8) - on the router page I have setup virtual server to forward to port 80 and 3389 still no joy.

Would like to get this working - any other ideas

LucFCommented:
>> I have one ADSL Router (Connection from ADSL router to access point is through Ethernet Cable)<<
So if I get it right, your setup is something like:

Internet => ADSL Router => Access point => your computer (10.0.0.8)
If so, you need to setup a little different kind of port forwarding.

On the ADSL router, you'll need to forward to the Access point, and then from the Access point you'll need to forward to you computer.
This as most likely the connection from the router to the access point has a different IP-range than the connection from AP to your computer.

all ips that we pick up from AP are on the same subnet 10,0,0,x

I cannot seem to log onto the access point

Will try with network card in desktop directly connected to ADSL router tmrw

Thanks
0
 
LucFCommented:
Ok, let's see then what IP you're getting from the ADSL router (most likely it's a different IP-address, in a different range)
You'll have to adjust the port-forwarding settings accordingly.

internet -----<wan port>router<lan port 192.168.1.1>-------<wan port 192.168.1.2>AP<LAN port>----PC<10.0.0.8>
so on the router forward to 192.168.1.2 and then on the AP forward to 10.0.0.8
adjust to fit your ip's

One ADSL Router - to AP and Desktop

One AP - to two laptop clients

What do you mean physical connections


For The ADSL their is only 2 Connections - 1 is the ADSL BT Line and the other is the Ethernet cable going to the Desktop.

I am trying remote desktop directly through The desktop.

Does something like this setup look like your network?

Internet => Router (IP range?) === AP (IP range?) ==== clients

If so, may I ask why you've (according to http:#13402704) got everything on the same subnet?
Please use different ranges for the connection from the router to the AP and the AP to the clients.

That to make sure that the router knows what to route where :)

my thoughts exactly Luc, I think they are trying to route to the same ip range (and confusing the router, need to be different ip ranges so the router can route)

Why would I need to

Please use different ranges for the connection from the router to the AP and the AP to the clients.


Can the adsl router not issues IP addresse through DHCP and the AP just pass through traffic

Forget the access point and concentrate on the Internet --> ADSL Router --> Desktop.

I try and connect to http://x.x.x.x/tsweb in Internet Explorer and it says HTTP  501 NOT IMPLEMENTED

Any more advice would be good.

stevenlewisCommented:
OK, if you have it setup like this (take the AP out of the mix for now)
Internet --> ADSL Router --> Desktop
and you have port 3389 and 80 forwarded to the desktop ip
then if on that desktop go to www.grc.com and run shieldsup and use the custom ports and check ports 3389 and 80

stevenlewisCommented:
>>ADSL Handles all IP Addresses through DHCP - AP Does not need to assign.

is the AP setup in bridge mode?
If not, then it is probably handing out ip's in the same range as the router, and there's the rub, can't route between the same network
it can not be
<wan port 192.168.1.x>AP<lan port 192.168.1.y>
it will not route if it is that way

What lan? You mean the internal network?
If so, try filling in the LAN IP in the box at that time.

Same for the web address, try http://<internal IP>/tsweb/default.htm

It all depends on which side of the router you're accessing.

Yes, that's like Steven said at http:#13419538 the problem with loads of routers, only a few will support LAN loopback.
Nothing you can do about this except for getting yourself another router, but I think that's not the way to go for just this minor annoyance.
But now I'm at a loss... I can't reach the tsweb page anymore, did you move it to a different port or such?
