net.link.ether.bridge_cfg: rl0:1,xl0:1,pcn0:2,ed0:2,
I'm running two clusters. rl0/xl0 (using public IP addresses) is the
one that's been involved in all the bugs I've been reporting. pcn0/ed0
(using private IP addresses) is for our children's computers.
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.
