No access via internet?

[ThomThom]

I'm running Ubuntu 8.04 on an old Epia SP 13000 which I plan to use as a file server.

I tried to connect to Remote Desktop via the internet, but I just get error messages saying UltraVNC/TightVNC can't connect to server.

When I connect using local IP it works perfectly. But it's the internet access I can't seem to get working.

I've forwarded the port I use for Remote Desktop to the Ubuntu machine. http://www.canyouseeme.org/ says that it can see my service on the port I've set up.

I also have the same problem with Twonky. I can access the web interface via local IP, but not when I use my public IP address.

Again, I've forwarded the port that Twonky uses.

Is there some configuration I have to do in Ubuntu?

It's a pretty fresh installation of Ubuntu. And I'm coming from years and years of Windows use. I'm not very familiar with Linux.

are you able to ping your computer ip from the internet? do you have firestarter or anything similar installed?

[ThomThom]

Yes, I can ping my IP.

I didn't have Firestarter installed initially. But I did eventually as I thought it was a GUI for Ubuntu built-in firewall. When I launched Firestarter and it asked me to set up a firewall I just cancelled it.
I'm still confused whether Ubuntu comes pre-installed / pre-setup with a firewall or not.

yes it does.. iptables.. does your port respond to this online port scanner http://www.t1shopper.com/tools/port-scanner/

Yes. For the port I set Remote Desktop it use it says:
<IP-ADDRESS> is responding on port 6000 (x11).
(Does Remote Desktop use any ports other than the one set up in the config window?)


For the TCP port Twonky uses it says:
<IP-ADDRESS> is responding on port 9000 (cslistener).

However, for the UDP ports that Twonky uses (1030, 1900 and 9080):
<IP-ADDRESS> isn't responding on port 1030 (iad1).
<IP-ADDRESS> isn't responding on port 1900 (ssdp).
<IP-ADDRESS> isn't responding on port 9080 (glrpc).


Is there a visual config for iptables? I'm used to typing commands from the days of DOS, but I prefer visual aids.

firestarter..
did you set remote desktop to listen to port 6000?? 5900 is the default port.

Yes, since I had problems initially I tried some other ports for the take of testing.


Are you saying that Firestarted is a frontend for iptables?

Yes
