This is my understanding as well. Were I in your situation, I think my somewhat ham-fisted approach would be to write a script to edit sshd_config and restart the service, using a dhcpcd hook to run it after the interface comes up. Not really elegant but I feel it might be simpler than the netfliter solution.
