Yes I enabled promiscuous mode and setautosrc 0 on rl0 via ngctl.
I can find no documentation on why this is done. Can you point me to some?

Yes I gave the jail a unique MAC address.

I tried to generate my own network map, but having problem.

ngctl dot > file.dot works.
dot -Tsvg -o file.svg < file.dot
gives me "command dot not found".
Tried ngctl dot -Tsvg -o file.svg < file.dot
and -T is illegal option.
What am I doing wrong?

Thanks for your help
Joe
