And yes, as far as I'm aware, the ARP reply is being seen by the DSL modem on the "external" side of the rl0/xl0 cluster. I did some tests last night with "tcpdump" to confirm this. If absolutely necessary, I could probably bring a laptop home from work, hook it up to the external segment (alongside the DSL modem), and run "tcpdump" on said laptop to further confirm what's showing up out there.
