Noob ifconfig question :-/ ...

[Gary Aitken]

> ... I have been tussling w/ getting my newly acquired WatchGuard FireBox
Edge firewall appliance setup. It requires a computer on the LAN on its
own IP block (192.168.111.0/8), w/ netmask 255.255.255.0. I was/am
trying to use ifconfig to set this box up on that block (temporarily
!!!) to get that thing setup & configured. When I (successfully) reset
my IP address to 192.168.111.27, I am able to access the device w/ my
browser. However, it asked for a user name & passwd, which I don't have
& which the manual which came w/ it doesn't specify :-/ .... Any clues
what those might be .... Slightly OT, I realize, however I will probably
later try to change it over to *BSD, as per an earlier post, in case
that helps .... TIA for any & all clues ....

A quick web search shows
  admin/admin

> Separately, when I reset the IP address of this box back to normal
(192.168.0.27), I could no longer access the web, or my DSL modem (on a
different subnet behind a router (to be replaced by the afore-mentioned
firewall)) w/o rebooting. When I did an 'ifconfig re0', I got almost the
same output as before my twiddling, except that the 'inet' & inet6'
lines were switched (inet before inet6 before twiddling, inet after
inet6 after twiddling) .... Could that be the cause of my inability to
access the modem & web ? TIA here also :-/ ....

That's because you changed the third digit of the ip address, and it is no
longer in the same subnet
as the rest of your network, which you just changed over to
192.168.111.27.  If I understand what you
said above correctly.  All of the boxes have to reside on the same subnet,
either 192.168.111.* or
192.168.0.*, in your scenario above.
