Hello, I've found the solution: the problem is related to this bug: http://defect.opensolaris.org/bz/show_bug.cgi?id=6130
The mac address is reversed (it appears also in the logs of the dhcp server). Using "pfexec ifconfig nge0 ether macaddr" fixes the problem. The bug is marked as closed in build 104, but the issue is still present in OSOL 2009.06 (the one I'm trying). -- This message posted from opensolaris.org
