Gotcha. :-)

Kurt's questions are pointing directly to the cause of the issue.
Thanks (and for your additional and correct help too), Kurt.

Cups daemon is working then as designed: it's only allowing from a
specified network to do admin tasks. Remember, if you change the ip
address of your ethernet card, then the @LOCAL macro is changing with
that too.

The former allowing subnet 10.230.199.x/255.255.255.0 (= @LOCAL) is
changed by that move: the new subnet to 10.230.189.x/255.255.255.0 can
now do the tasks. Which means noone is any longer allowed to do admin
tasks from 10.230.199.x, but from 10.230.189.x

You can fix this in too ways, and everytime /etc/cups/cupsd.conf needs
to be modified:
1. Either create an explicit rule to allow admin tasks from
   10.230.199.0/255.255.255.0 and modify the </admin> section
   appropriate:
     <Location /admin>
       [...]
       Allow 10.230.199.0/255.255.255.0
     </Location>
     <Location /admin/conf>
       [...]
       Allow 10.230.199.0/255.255.255.0
     </Location>
2. Or change your subnet mask to 255.255.0.0, and allow everyone (in
   changing so) doing admin tasks

and a "/etc/init.d/cups restart" after changing modifying config file
is necessary: to notify daemon about reread file and change
appropriate. To point it out: a reboot is not neccessary to do so.

The final decission which of both solution to use, is up to you.

and I can suggest you reading Kurts helpful comments in previous
e-mail regarding outdated config params, etc. Thanks.

Regards,
	Klaus.
