Re: wireless bridge (almost) working.

[Russell McManus <russell_mcmanus%yahoo.com@localhost>]

Following up to myself, this turned out to be a problem with dhcpd
configuration.  The mac os x Laptop would receive a dhcp response from
Router, but afterwards the routing table on the mac os x side was not
correct.

When I manually fixed up routing on mac os x, everything worked.  Now
I just have to figure out what mac os x considers to be a complete and
valid dhcp response...

The bridge is working perfectly, thanks NetBSD!
