I am having some serious difficulty with dhcp, carp, and vlans. I have
two OpenBSD/i386 3.9-stable firewalls running GENERIC. I am using them
to replace a failing Cisco Catalyst 3550 switch that was doing the VLAN
routing. The boxes are working great as far as the VLAN routing goes but
DHCP is not working right. On the Cisco, I could use:
ip helper-address aaa.bbb.ccc.ddd
This would send the DHCP requests to whatever server they needed to go
to. I have been trying to use dhcrelay on the firewalls for this purpose
with dismal results. If a DHCPREQUEST for <ip> comes in, all is well,
but if a DHCPDISCOVER request comes in, DHCPOFFER does not seem to reach
the client.
I figured that I should put the DHCP server on the actual network with
the clients using a vlan(4) interface so that no "relaying" would be
needed. The exact same problems seem to exist with this setup.
I am up late again on this problem and I am hoping someone can give some
much needed insight. Two dmesgs are below. The first is for one of the
firewalls and the second is the dhcp server.
