If you are using slirp networking you can forward a port by adding to your prefs file a line such as the following:
Code: Select all
redir tcp:8000:10.0.2.15:80
The code is online here:

You can find a Linux binary, built on Fedora 17, here:

I'll try to add a binary for OS X soon.
Here is a screenshot.

Present issues:
- When a program in the emulator listens on a port, at least with TCP, there is a delay of 16 seconds to start the listening. When connecting from the host there is sometimes another delay of 16 seconds. When connecting from other hosts there does not seem to be this delay.
- Using 0.0.0.0 as the client address does not work well, so you have to specify the client's address if it is something other than 10.0.2.15 (although in my experience it is always 10.0.2.15).
