I have an airport base station sharing a DSL connection. I would like to be able to serve FTP off a Jaguar machine.

I have set a manual 10.1.0.201 IP for the laptop and set up port mapping to send ports 20, 21 and 80 to 201.

Finally I set up dynDNS to map my dynamic external IP to a domain name.

But it doesn't work!

I can ping my domain name or external IP but not connect to either http or ftp: they time out (both services active, firewall off)

Some people are telling me this is a bug with airport: has anyone here served from behind Airport over aDSL ?

Thanks,
Marc

Earlier Airport base stations had a bug? that prevented internal users from hitting the external ip address and 'bouncing back' inside.

So while the port mapping is set correctly, and external users can get through to the internal servers, internal users couldn't.

This may be your problem. I believe that upgrading to the latest AirPort firmware addresses this.

The second option is that your ISP is blocking incoming connections since running servers on a residential account isn't permitted under their terms of service. In which case your option is to upgrade to a commercial account where you can run servers, or switch ISPs to a provider who doesn't limit incoming connections.

I've got exactly the same problem - and I probably know less about networking than most so thats not helping...

I set up my dyndns account. I mapped the relevant ports to 201 (20, 21 and 80) The serving mac has an IP of 10.0.1.2 so I assume thats the private IP I am forwarding to.

I too can ping the my dyndns account. A port scan reveals 5009 to be open but that's all. No open ports 20, 21 or 80 show up.

Is there a manual for beinners like me? I googled for quite some time with no real results.

Thanks.
