Bridge Usb0 And Wlan0 Options

[colin]

Hi,

I am sure the answer is in the forum somewhere, but I can not find it and I am stuck.

I have C1000 and have installed 3.5.4.1. I am trying to connect to the internet via my laptop using a bridge on the laptop between usb0 and wlan0. The wlan0 connects to my ADSL router.

I think I have followed the procedures on the OZ web site and in the pinned connection topic in this forum.

I have got it to the stage where the C1000 talks to the laptop and the laptop will talk to the world, but the bridge does not seem to forward between usb0 and wlan0 (no ping from the C1000 to anything other than the laptop.)

I am now stuck. The laptop is running slackware, and I will try on the slackware forum if that is the right place to ask.

Hope someone can help.

I have appended the output of some commands below.

Cheers,

Colin

So here what is set up laptop
