The rub is that the address family this arrangement uses is 169.254.0.0/16, which is unsupported by their main LAN's Adaptec 3000 router. (The router will serve DHCP addresses in that range, but won't pass traffic out to the internet.) > > Putting the Canon on the main LAN (192.168.*.*) and setting it to use DHCP doesn't work: it gets assigned a valid 192.168.*.* address, but remains undiscoverable. This is true even if I set it manually to use a fixed 192.168.*.* address, and use "IP Printer" setup on the Mac. No go. The whole APIPA address mechanism <http://packetlife.net/blog/2008/sep/24/169-254-0-0-addresses-explained/> is problematic. Things that depend on APIPA either work properly straight out of the box, or never work at all and can't be fixed fo work. The only devices I've encountered that use APIPA reliably and transparently are TP-Link powerline network extenders, and if you want to give them real addresses, they switch over to those seamlessly to boot. _______________________________________________ MacOSX-talk mailing list [email protected] http://www.omnigroup.com/mailman/listinfo/macosx-talk
