I have a TelstraClear cable connection in Wellington.

I have an elderly Belkin router, model F5D7230-4.

The router supposedly offers the capability to forward requests from a given port range to a given server on my LAN. And the browser-based UI for the router does let you specify a source port range, a destination port range, TCP or UDP, and a local IP address.

I can get this to work with standard ports. Eg, if I specify a range of 80-80, it WILL forward HTTP traffic to the host of my choice. If I open range 22 -22, I can SSH to a host of my choice. So far, so good.

However, I think I'd prefer to run on non-standard ports. I'd like to run SSH on a non-standard port. I'd like to have a security webcam on HTTP on a high-numbered port. And this just does not work. Eg, I can't get HTTP to work on port 8080 (or for that matter, 81).

Is this because TelstraClear is "helping" me and blocking all but a handful of ports, or is it my crummy old consumer-grade router? I am willing to go and buy a nice Linksys WRT54GL to achieve what I want, but not if the fault isn't at my end.

Update: on re-reading, I see haven't made it totally clear that I'm talking about enabling incoming connections from the internet to hosts on my home network, not the other way round.

Gah. I solved my own problem.

Although the UI in my router implies that it will forward inbound connections on one port to another port on the destination server, in fact the port numbers have to be the same. It will not forward port 8000 to port 80 another host; it will only forward port 8000 to port 8000 on another host. This is not documented in the manual, I swear.

Thanks for reading and thinking about this anyway.
