I still do not understand why it happens even though I can understand why it would be an issue. I did some web searches on linux, dhcp, and discovery protocol but all I found were references to CUPS, a Cisco (specifically) discovery protocol, and lots of stuff that seemed not useful. Can you point me to a specific solution or to any references that would help resolve this issue in an automateable fashion (without me needing to be a guru)? BTW, a reminder that both interfaces get the same DNS IPs from the one router acting as a DHCP server. So the issue may be with the dhclient effects but somehow the effect seems to change which interface traffic is going to. --------------------------------------------------- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change you mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
