Patrick, I concur with what you said and it's what I was doing for years' past.
If need be I'll revert but I was kinda giddy to try the new code.

I have some debugging information that I just acquired if it helps.
I have determined that the bridge isn't receiving arp requests that
are being sent by Jail 1; the machine with the trunk
I have also determined that the bridge *is* receiving arp requests
from Jail 2; the machine that is labeled as 'access' or untagged.

The only difference between the two here is that in my scenario, Jail
1 does it's own tagging while Jail 2 doesn't and leans on the bridge
for its `access'.

Thanks Gents!
