RDP connection to a Cable Router

[dtmpower]

I have NTL and a cable router...is there anyway to make a connection to the router from the internet, for example for remote desktop connection ? My brother has adsl and his router has www.dyndns.com support installed on it. But I can't find a cable router that does this... NTL charge for a fixed ip address and I am not sure if the ip address I get at the moment on my modem will work - I think it shares amongst several customers modems' - anyone got a idea/help ?

I dunno if NTL is being wacky with its IP's, but normally you'd just use the PC based dyndns client from www.dyndns.org, configure the router to forward port 3389 to your PC and make sure you've got good passwords on all the accounts allowed to log in remotely. Oh and allow port 3389 incomming if you've got a software firewall on your PC. Hope that makes sense?

Cheers

That wont work as how will dyndns know the ip address of the router unless it is imbedded in the router like zxyel adsl ones... if dyndns is running on my machine it wont know the external ip to set to... my pc cant see the outside world...

You would think that, but it does!

I cant see how it will work....there is no external ip address listed anywhere apart from the cable modem...

I suspect the DynDNS client just contacts the server and the server decides where it's been contacted from. Much more reliable.

It does. I set this up yesterday on mine.

1: Download a dyndns client (i used directupdate)
2: Sign up for an account (i used sitesolutions)
These next steps may be different for other ddns services
3: Register a domain name (free generic, or your own)
4: Add an A record of your current IP address (your client will detect this for you)
5: Make it into a DDNS record
6: add teh user details and ddns ID from your account into your client
7: off you go

Configure whatever ports you want forwarded on your router. I've got default RDP going to my desktop and another port natted to rdp on another machine. Unfortunately my ISP blocks incoming port 25 and 80 so no mail or web servers for me.

I've currently got 4 dyndns hosts updating in this way. I haven't bothered to look into exactly how it works, I can think of a few ways but it doesnt seem important right now...

In which case I will try it and see might be moving house soon to adsl - so will get a fixed ip or dns enabled router
