Client Mac shielding

Post by mdcoll25 »

Hi there.
When using Gargoyle , does anyone know if client MAC addresses are shielded under the 2 type of wireless configs below ?

1. Client connects wirelessly to an AP that is wirelessly connected to another AP via WDS

2. Client connects wirelessly to an AP that is configured as a wireless client-wireless bridge , and also has a virtual AP added to allow many clients to connect wirelessly to it.

My application requires that client MAC addresses are transmitted transparently.
EG , my whole wireless network connects users to a Radius Server for authentication.

Cheers for any input given.

This will work with the WDS bridge, but not the client bridge. The way client bridge is implemented, it's impossible to make the bridge 100% transparent (which is also true of client bridge on other firmware such as DD-WRT).

You may not need mac transparency - certainly my RouterOS based hotspot looks at the IP address of the client not just the MAC address...

But as Eric says as soon as you have a wireless client involved then everything behind that will have the clients MAC address due to the way 802.11 works. The only way round that is to use WDS or a proprietary solution (eg I think engenius have a system called 'root bridge' on some of their AP / Client units that uses 4 address mode the same as WDS)
