That's a good idea I didn't think off :) I messed with amd(8) once
before and ran into trouble. I can see in this case it would be ideal,
and shall have a go at getting it to play nicely.

Yes, I had looked at this. However, I was meaning trying to have a
solution where a different set of firewall rules would be started based
on the assigned IP address.

Yeah, I think I can see that this might even be a good place to
start/stop (stop if required, I haven't read amd(8) yet) amd from.
Also, I can set my symlinks in case the reason is not one of yours
listed.

I use start_if.ep0 to set the media for my network card. Does this get
re sourced after dhclient has done it's magic? I was under the
assumption that it got executed /before/ dhclient, and would therefore
be of little use to set variables based on the output of dhclient... ?
Many thanks! You've given me some excellent ideas. I'll tell you how
I fare.
