Help with DNS Thing....

[rejieah]

Greetings!!!
I would like to seek help to those who know Internet DNS things.
The scenario is this:
I am working i a small company, with dsl internet connection, our isp provide us with 2mbps connection, web hosting, static ip and a multi-static ip (ip/30), we also have a registered domain name. My problem is that this domain name is registered via one-time/lifetime registration and the registrar won't let us change anything on it, any changes mean so much cost and so much hassle due to many papers that are needed by the registrar.
I want to setup an ftp server, host some web or make my server seen remotely via internet but i think i can't because of my problem, coz i can't edit my domain name config.
I am thinking of using some free dns solution like the dyndns.com, can this be possible? how does it work? how to configure it?
Please help. Thank you!!!!

rejieah,

If you have a static IP and the DNS entry for your domain name is pointing to that IP address - you basically need to forward (NAT) the FTP ports (TCP Port 21) from your router to the node on your LAN that's running your FTP server.

Go to the support site for your router and you should be able to find specific instructions for forwarding FTP traffic to a specific node/machine/server on your local network.

Reply with the specific make/model of router and the make/model of the FTP server system as well as OS and revision.

Thanx john for the reply.
My problem is I can't manage entries on DNS for my domain name coz it's locked for editing due to its registration as lifetime domain, all i can see are the nameservers supplied by our isp.
I want to have an alternative if there is any for me to see my ftp or web or my server/computers outside or via internet.
by the way my router is a Prolink Hurricane 9000P ADSL Modem/Router supplied by the ISP.

rejieah,

Go to:

http://www.fida.com/manuals/h9kv1.pdf

This is the manual for your ADSL modem/router. You'll need to access via a web browser on a pc attached to this router (see page 12). Look at page 18, which describes NAT settings. You want to set up NAT to forward TCP Port #21 (FTP) to the IP address of the PC or server on your local network running the FTP server.

You shouldn't need to mess with your DNS records to do this. The only reason you'd need to change your DNS records is if you wanted to redirect FTP traffic to a different physical internet address. If all of your PCs are using this router and the same external IP address, you should be able to setup a NAT port forward on the router.

Thanx fro the reply.
I created a local DNS in Windows 2003 Server, i configure on it ftp, and intranet and planning a mail server on a windows 2003, i add ip address corresponding to ftp and intranet, so the windows 2003 server box has multiple ips.
With regards to your reply, i will have to configure my router, select the virtual server configuration, add in the ports and specify the ip address of my ftp based on the ip address i gave on my local dns.
Can i do the same on mail, i saw smtp and pop3 on the manual, is it possible?
Thanx again, i hope to learn more from you, you're a big help

rejieah,

Yes, you can configure port forwarding on your router to redirect IP traffic on specific TCP and/or UDP ports to an internal IP address on your LAN.

Check out:

for a listing of specific TCP/UDP ports and the apps that use these ports.
