Sunday I got round to setting up my Netras. They now all boot, and see the network. But the network sees them not. They go into a router, that's connected to a wireless ethernet adapter. The problem is, the wireless adapter only accepts packets that are addressed to the IP of the last device to route packets out of it, so only one of the four machines on the router is visible at a time, chosen by a race-to-boot.
The alternative to using it as a bridge is to use it as a wap, then make my ADSL modem a client, so I may try that as an alternative.
