Hello,
I'm in the process of migrating my router/firewall system from FreeBSD
to OpenBSD and I came across a minor problem. I want to have a static
alias address on an interface that is otherwise configured with DHCP.
What I had in FreeBSD was this entry in /etc/dhclient.conf:
alias {
interface "vr0";
fixed-address 192.168.1.200;
option subnet-mask 255.255.255.0;
}
This seems to be silently ignored on OpenBSD 5.7 and the dhclient.conf
manual page makes no mention of alias declarations. How am I supposed
to achieve the same effect?

Perhaps something like this in your /etc/hostname.vr0 instead would work
for you?
dhcp
!ifconfig vr0 alias 192.168.1.200/32
No, doesn't work. Interestingly doing the alias manually when dhclient
is running and vr0 has a public IP address from DHCP:
sudo ifconfig vr0 alias 192.168.1.200/24
This kills dhclient(8) completely and removes the main address.
Any other ideas?

The system log /var/log/messages reveals:
Jul 27 03:01:30 firewall dhclient[23894]: 192.168.1.200 added to vr0; exiting
Why is this done in so bizarre fashion? It is not unusual to want to
have a static alias address on an interface that is otherwise
configured with DHCP.

I can't test this, but from what I'm reading I think this should work
/etc/hostname.vr0
dhcp "alias 192.168.1.200 netmask 255.255.255.0"
