Cisco 677 ADSL

I'm having some problems here. I want to setup a ftp server... Also be able to play multiplayer games with people connecting to me. However, my dsl modem (router, same thing...) doesnt do it. When I goto winipcfg, my ip address shows up as 10.0.0.2 ... The gateway is 10.0.0.1 ... When I goto alltel.net, it tells me my ip address is 166.102.254.35 ... When i ping it, it works. When i run an ftp server, it tells me that my ip is 10.0.0.2 ... No one can connect to me! No matter what! How can I do this? Alltel won't give me tech support on this issue, and they told me that the site that tells me how to do it, is down. So im clueless. Hopefully someone out there can help!

What you are looking for is NAT. More specifically, NPAT. You have an private address configured on your network, and you're right: no outsiders will ever be able to surf from it. What you need to do is, using NPAT (Network Port Address Translation), configure your router so that every request that comes to the FTP port (TCP ports 20 and 21) is redirected to 10.0.0.2


Your router has two IP addresses. One public, and one private. What NPAT does is translate these addresses. Once it is configured, you advertise your FTP server as your Public address 166.x.x.x.
When it receives an ftp connection to this address, it automatically sends it to your ftp server. This means that your ftp server will receive a connection to him (10.0.0.2) from the router's INTERNAL, or private, address (10.0.0.1). It will send the results to the router, and the router will forward them to the machine on the Internet that requested it. It's transparent to the client machine on the public network. The only thing is, you need to advertise your public IP. You can even have different machines doing different things. For example, and FTP server receiving ports 20 and 21, and a different machines being the HTTP server (receiving port TCP/80).

You can find how to configure NAT on your router in:

Do a search for NAT and your router model.

Good luck,

Andre

I did some of that stuff... And then my dsl stopped working, so I had to reset it. Maybe my isp doesn't support it. However, they said they do, just don't give the tech support. Is their a cisco person i can call?
