How to disable adb port forwarding?

Question

How do I disable a port forwarding rule in adb that was previously enabled with

    adb forward tcp:1234 tcp:1234

Is there any other way than killing and restarting the adb server?

Answer 1

Try adb forward --remove tcp:8080, or adb forward --remove-all.

This was added to adb in December 2012

Answer 2

Setting Up Redirection through ADB

The Android Debug Bridge (ADB) tool provides port forwarding, an alternate way for you to set up network redirection. For more information, see Forwarding Ports in the ADB documentation.

You can also remove a redirection by killing the ADB server.

However you can use network redirection provided by emulator console, which provide ways of removing. To access type:

telnet localhost emulator_port

usually first emulator runs on port 5554.

use command "rdir" to add, del or list network redirections.

See documentation in Using Network Redirection.

Good luck.

EDIT:

To stop forwarding use

adb forward --remove tcp:<port>, or adb forward --remove-all.

This was added to adb in December 2012 (see patch here). The SDK update released for Android 4.3 (API 18) was the first to support it.
