How do I setup a dynamic address using DSL?

[Usalabs1]

First of all, I'll describe the network connections, starting from the main computer.

Main computer connected to an auto, 5 port switch, from the switch to the DSL, from the switch to the computer in the bedroom, the DSL modem is a gateway with DHCP enabled.

I can connect to the internet from either the main computer or the bedroom computer.

When I had dialup, the main computer would be the DHCP server, but now, the DSL modem is the DHCP server.

I have also setup IIS as a webserver, I can enter

http://desktop/xxxxxx

into internet explorer, and get to the webserver, but if I try to setup a dynamic IP address (at dyndns.org) then use the

http://mysite.gotdns.org

address, the ip address detected ALWAYS enters the admin of the DSL modem not the webserver, when I had dialup it was no problem, but DSL seems to more of an impossibility.

How can I get a dynamic address to point to the webserver?

I presume that you are using RFC1918 private address space on your LAN. I also presume that your DSL modem/router gets only one 'real' IP address on the outside, and so that will be the address registered at dyndns.org. What you need to do is set up port forwarding on the router so that port 80 requests directed towards the routers address are forwarded to the IIS server on your LAN.

I don't understand, I know how to get to the port forwarding, but I don't know where to put things, these are the settings as displayed:-

IP Port Range Protocol IP Address
from to

these are the only settings that are displayed.

 

[ChrisAC]

Port TCP 80 directed at your external address should be forwarded on port TCP 80 to your internal address.

iproute, I still don't know what to enter into the boxes, anyway, I have setup up the DSL modem for remote admin on 67.41.21.136:80

Username: admin
Password:12345

if you could setup the port forwarding, it would be much appriciated. Thanks.

I've tried using port forwarding with all ways that the ip address can be used, and regardless of config, the external ip address ALWAYS gives access to the DSL modem webadmin, which concludes, that msn dsl CAN NOT be used to setup a webserver.

 

[ChrisAC]

Then you could forward another port to port 80 internally.

I would like to point out that, MSN DSL, DOES NOT and CAN NOT allow access to a local webserver from outside the lan, my advice to everyone that is thinking of getting MSN DSL, DON'T!, MSN have you by the B**ls, if you want to host a website using MSN DSL, pay for their hosting, dns servers, and domain name(s).

Because of the internal sofwtare of the DSL modem, the only use of the modem is for downloading and surfing, PERIOD.

I know, I've tried every concievable configuration and the modem will NOT permit any other use but as layed out above.

You have your DLS modem admin setup for 67.41.21.136:80.

From your above post, I take it that it is hardcoded into the DSL modem? Will they let you install your own modem that you have more control over?

But, yeah, until you can find a way to change that admin port you're kind of stuck. Unless you want to use https for everything and use port 443.

I've not used MSN, so I'm not familiar with their policies. I'm fortunate that my DSL provider told me in writing I can use my DSL for anything I want (legal stuff only of course). No bandwidth throttling, no server restrictions. For $35 a month they rock! Too bad they are local only.

I was right, MSN have a deal with Actiontec to create a dsl modem with everything in it, firewall, nat, port routing, dhcp server, etc etc, which can not be changed, which means that when a user signs up for msn dsl premium, you can only use the modem for what msn want you to use it for (surfing, messaging, and downloading), hosting a local web/ftp or audio streaming server? forget it, Actiontec dsl modems are so designed to prevent any of that, and I thought highspeed was the in thing, I'm going back to and sticking to DIAL-UP, it maybe slow, but at least it don't have all the crap that a dsl modem has, AND!, I can host a local web/ftp and streaming server,

I don't really think that your experience with MSN DSL speaks for the masses. I have been using SBC DSL for many year now and have had no trouble hosting my own webserver. The trick is to use a DSL modem that is just that, a modem. By that I mean a DSL modem with no router functionality built-in. Then you can use whatever router you want. I don't know if MSN forces you to use their router, but maybe you can request just a modem from them. I know SBC offers some sort of home network package whereby they give you a modem/router. But you can opt out of that and save some money. Perhaps MSN offers something like that. It's worth looking into.
