SpeedTouch routing: cannot connect to certain ports remotely over internet

I am currently using the SpeedTouch Pro router with AOL broadband.  I am trying to set up a web server and connect remotely via telnet and ssh to my 2 machines (pc runnning win xp and pc running linux).  I signed up for dynamic dns since AOL do not provide static IP.

I have configured my NAT settings on the SpeedTouch router to open up ports 23 ,22, 80 etc etc respectively but on the inside IP address, I got confused so I assigned each port to the computer running the particular services ie. I assigned port 23 to my XP machine (telnet) and port 22 to my linux box (ssh).

I have tried accessing it from work and no luck, it cannot get through, however, it can ftp my network remotely.  Bizzarre.

I also tried port scanning from work and it showed that all ports are filtered even the ftp, although I managed to get into it ok.

i am a newbie in networking, anyone with any suggestions would be greatly appreciated!!!

Ahh okay; I think I know what you're asking now.  Unfortunteatly I don't know the in's and out's of that particular router; however on other models I've worked with you need to enable the ability to access the router's setup from the public side (usually disabled by default for security purposes).

Something to consider is that if port 23 is already being forwarded to your XP box, then a different port would have to be used to access the router's internal telnet service (seeing as the IP address is the same in both cases).  Are you sure the router supports telnet for it's setup? An internal web server is also common; in some cases it can only be done via a comm port on the router itself.

There may be a few issues here;

1.) Does AOL permit you to run a web server on port 80? Some ISP's block port 80 which will force  you to use a different port (also meaning that to get to the server you would need to append the port number in the url ie: http://xx.xx.xx.xx:8080 ... take note that you need to specify the http:// in this case because browsers will not recognize the port as a web address otherwise).

2.) You are testing with the PUBLIC ip address that's currently assigned to your modem right? No insult intended, but a common mistake made by some people.  You should see the applicable ports open when you scan the IP address; check your router settings again to see if the ports are indeed being forwarded to the applicable box.

3.)  Not sure why you are opening TELNET to your XP machine... where does the webserver run? Keep in mind that TELNET requires that the host server has a service running for it...

thanks for commenting, I have asked AOL if they block any ports and they responded with a confident "no".

I have managed to access my telnet service remotely and the webserver!

My webserver runs on the xp machine, and I have got the telnet service running as I can access all services and ports from within the LAN and outside.

However, I cannot access the telnet service that my router provides.  I am confused on how to set it up in order to access it remotely...  I also cannot ping to my network remotely and do not know if the router is blocking pings or not, either way, I do not know how I could configure that, is there a special ping port???

I totally get you.  Yes the router accepts telnet from within the LAN.  Thanks for your help, greatly appreciated mate.
