Now, your bridge should bridge this dhcp-packet from one interface to the
other? That doesn't work: its sending this packet out through that
interface, it can't send it out on all other interfaces.
So there's no solution? I see now that
I'm still confused.
Why do you need to succed in getting a DHCP address for _both_ interfaces?
Wouldn't it be OK if jsut the one that hapened to face the DHCP server came
up? This would still give you remote access.
I can get away with DHCP on one side only, but having actually tried

My experience is that greylisting requires at least 2 failed attempts.
Maybe my pf.conf isn't setup properly. But, there's always 1 'extra' failure
that seems to me should pass through.
James is right, it's a design flaw of spamd that two failed attempts
are required. This is what happens:
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
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
Maybe I'm not understanding the problem, but for a tranparent bridge, you
wouldn't want it to be assigned an IP address on either network card. hence
the transparent part.
You would think so, but you would be wrong. As I was when I started
this project. In OpenBSD a bridge must either have
The only fix for this is a *major* redesign of spamd (or equivalently
incorporating spamd's greylisting code into a spamfilter which *does*
relay connections at the IP level to an MTA - which is actually what I'm
working on at the moment)
Why start from scratch ? There are enough seasoned,

I appreciate the insight. I do realize it's a difficult problem but,

Nope there's just not.
There is, but not with spamd as currently implemented.
It *ought* to be possible to configure both hostname.xl0 and hostname.fxp1
