Help! Need to forward ports on N900
 

Hi,
Help! I need to forward port 5800 to my laptop. I'm tethering my laptop behind my N900 and I need to remote share my desktop via UVNC. I can do loopback so I know that port 5800 works on my laptop but any system outside can't connect to that port. I can tether via BT, cable or Wifi.

I don't know if I can do this with IPfilter but I am using the custom kernel. I figure if I'm use Joikuspot can I do a custom NAT filter in IP Filter?

How can do it if I'm tethering via BT / Cable? I'd prefer this because Joikuspot fails about 10-15 minutes. I can move to Mobile Hotspot as well.

Thanks.

Does anyone know if the telcos block incoming connections? I use T-Mobile.

I know that Vodacom in South Africa for example block access - IPs are not world accessible unless requested to be, so yes, you need to know your telco's policy...

you might be able to tell by the ip, mine is 10.x.x.x so the cell phone company is obviously not giving me my own internet accessible ip. 10.x is a reserved range if you didn't know. if you have a special data plan FOR TETHERING then they might give you a real IP. My provider, WIND, doesn't even allow outgoing connections without one of those special plans. I mean I get Port 80 and whatever else they think I deserve, but that's about it...

When you are sure the external IP address is connectable, you can do a simple command with netcat (apt-get install netcat from extras-devel) to redirect from <EXTERNAL IP> <EXTERNAL PORT> to <INTERNAL IP> <INTERNAL PORT> like that:

You also have socat (Socket CAT) in extras-devel, a more powerful command-line utility, but also much more complicated.
