Ok I got it working. Here is what I did
Enabled multipath routing (sysctl)
Added the relayd anchor to pf.conf
Created a relayd.conf with this in it
gw1="fxp0"
gw2="fxp1"
table <gateways> { $gw1 ip ttl 1, $gw2 ip ttl 1 }
router "uplinks" {
route 0.0.0.0/0
forward to <gateways> check icmp
}
Started relayd
Reloaded pf.conf
I then could see with 'relayctl show summary' my two gateways and their 'up'
status as well as the default route to each with 'route show'. When I 'ifconfig
down' one interface, 'relayctl show summary' showed it as down and then default
route to it was removed automatically. Awesomeness.

I just watched Reyk's youtube. I'm going with relayd. I can see the 'routers'
section in the man page for relayd to do what I want.

Subject: Route-to with a dynamic 'next hop'
Greetings all -
I have 2 internet connections. One of them is static IP, one is dynamic. I want
to use both of them on my gateway. From the man pages and other docs I see the
use of route-to in the pf.conf including the 'next-hop' that it requires. This
is easy enough. Problem is that the next hop is hard coded IP in all examples.
I need that next hop to get updated when my one WAN DHCP link is updated. I
know about if:peer, if:broadcast, if:network ect but there is no if:gateway.
Seems like you could have used dhclient-script to adjust pf config when ip
changed but dhclient-script has been removed. I also read that relayd has
become the best option to accomplish this uplink load balancing in current
versions of OpenBSD. I wanted to check with you all to make sure I'm not
missing something basic with the load balanced uplink scenario in OpenBSD. As
always, comments and suggestions are much appreciated.
