Ok this post sent me on the right course:
http://www.going-flying.com/blog/mikrotik-openbsd-ikev2.html
Here's what I did:
cd /etc/ssl/vpn/private
openssl rsa -in x.y.z.t.key -pubout -out ~/x.y.z.t
... copy ~/x.y.z.t to /etc/iked/pubkeys/ipv4 on the home router.
After that the VPN works, I can send packets from a machine at home
and I'm seeing them on enc0 on the remote server:
# tcpdump -n -i enc0
tcpdump: listening on enc0, link-type ENC
05:14:04.103254 (authentic,confidential): SPI 0xd51e3910: 192.168.7.2 >

10.0.0.102: icmp: echo request (encap)
...
However, I'm now running into what seems to be a firewall problem,
an I'm getting no answer. I do have "pass quick inet proto esp" on both
VPN ends. Any idea where / how to fix this?
Also, IPs aren't assigned automatically to the VPN ends. I can
add them to hostname.enc0, but is this the right thing to do? I tried
adding a line
config address 10.0.0.102
to /etc/iked.conf, but that's rejected as a syntax error. A clue stick
again please?
