Using one like you suggested: # ethernet address increased by 1 in the last digit ifconfig ue0="ether b8:27:eb:71:46:4f inet 50.1.20.28 netmask 255.255.255.0" produced a flood of errors during boot: ifconfig: interface ue0=ether b8:27:eb:71:46:4f inet 50.1.20.28 netmask 255.255.255.0 does not exist There was clearly no network connectivity, but the serial console remained responsive. The host sharing the same MAC address exhibited no connectivity problems. Another suggestion was found in an old forum post, assigning the IP in the usual fashion but adding an alias: ifconfig_ue0="inet 50.1.20.28 netmask 255.255.255.0" ifconfig_ue0_alias0="link b8:27:eb:71:46:4f" (trading ether for link had no effect) resulted in the gateway (and everything else) being unreachable. Thanks for writing! bob prohaska
