I got the mask reset earlier, & can ping more stuff now, just can't get
this address reset. I need to do this to configure a newly acquired
WatchGuard FireBox Edge firewall appliance (to be later possibly
reprovisioned w/ NetBSD/FreeBSD/OpenBSD, as per earlier post on another
topic). TIA for any further help :-) ....
