Graham, I use a bridge and assign the IP to one NIC, albeit statically assigned, on several "production" OpenBSD 3.5 systems. If I ever switched the IP to the Other NIC, I would lose connectivity until the ARP tables on the various LAN hosts updated with the new MAC address. Maybe about 10 minutes if I recall. I don't recall what the times are for ARP table refreshes average.
Agreeing with what another individual said regarding this post, it's a transparent bridge, so that IP living on multiple NICs is a really moot point. I would venture to guess that the kernel gets really annoyed having to track an address on two different NICs with or without a bridge in place. best regards, Jim [EMAIL PROTECTED] wrote on 10/26/2005 12:42:43 PM: > I wanted to set up a system which has two ether cards (it's part of > a transparent bridge so it'll be inline with someone's connection) > such that it'll pick up a DHCP address on *both* cards ... the trick > comes from not knowing in advance whether the DHCP server will be > on the inside connection or the net-facing one.
