Routing problem

[mennie]

Hi,

I have one of these free Telkom ADSL modems. Its a "ADSL MPC850" and I can't get a webserver with dyn. IP working.

Is there somewhere a tutorial?

Kind regards

Melanie

(This is moderatly technical, so let me know if you need a more (or less) technical howto).

I have two servers running mail and web for my development work (all in a test environment) all running off dyndns and a LinkSys router. The servers are running RHEL.

Not quite sure about your modem, but if it is a router type, then you need to do at least two things:

1) Set up the router so requests to port 80 are directed to your PC
2) Ensure that if you are using XP SP 2 that your XP firewall allows port 80 requests, and if on Linux, that your Linux firewall allows HTTP traffic.

That should sort it.

One other try, is to determine your public ip address (dyndns tells you, or use checkip.com - and then ping your dyndns name from another internet connection and see if the name resolves to the public ip).

I have a Telkom router and I made me a free account at www.no-ip.com and run the software thingy that comes with it on my pc. That seems to work.

As for port 80.. obviousley xp firewall wont block that, hmm but won't it interfere with web browsing if you forward all port 80 to your ip? Shouldnt the webserv be on port 8080 or something?

Ports work two ways - incoming and outgoing. The router forwards incoming traffic destined to port 80 to the ip address you specify - when the connection is made, all works fine.

However, any pc can still go out on port 80 - so no, the 8080 option is not required.
Yes, XP most likely will not block port 80 by default (long time since i used M$), but on linux you need to allow it specifically, as it is blocked by default.

(also, ftp = port 21, ssh = 22, windows terminal server (remote desktop) = 3389(?), vnc = 5901+, mail = 25 and 110, so open all those if you need them).



Hope that helps,

Telkom Alcatel MPC850C Router/Modem

I received an old, but working MPC850C ADSL modem from a friend.

However, he has lost the username/password for the setup utility and I cannot change the settings for my account.

Does someone know how to do a "Factory Reset" to reset all settings and passwords to default, or know where I can find a manual?

Any help will be appreciated.

Thanks

There should be a tiny hole somewhere on the router for a pin to fit in.. hold in it in there for like 10 secs

Melanie, I'm just guessing here, since you haven't stated exactly how you tested it, etc.:

It could be that your router doesn't support NAT loopback, meaning that you won't be able to access the website that you're hosting by using the Dynamic DNS address since you're behind that router.
Have you tried accessing the webserver/website with another Internet connection?

If this is the case that you cannot use the Dynamic DNS address from one of the PC's behind that router, then you could simply modify the %windir%\system32\drivers\etc\hosts file, by setting that Dynamic DNS address to point to the LAN address of the webserver.
eg. if your server's ddns is mywebserver.dyndns.org pointing to 196.xxx.xxx.xxx, with the LAN IP address of the webserver being 10.0.0.3, then add the following line in the hosts file:

10.0.0.3 mywebserver.dyndns.org
