Ok - looks like you've done everything right. I remember that it was broken when new ARP code went in, but thought it was fixed already before FreeBSD-8 came out. I get an ugly error message on current, but at least it setups the address: [98]chipmunk.cicely.de# arp -an ? (10.1.1.9) at 00:1c:c0:94:2c:d7 on vlan0 expires in 1016 seconds [vlan] ?

I don't heve enough clue about ARP code in FreeBSD to fix it. You should file a PR so it can get picked up by the guys who designed the new code. -- B.Walter <be...@bwct.de> http://www.bwct.de Modbus/TCP Ethernet I/O Baugruppen, ARM basierte FreeBSD Rechner uvm. _______________________________________________ freebsd-net@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-net To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org"
