Might be time to change my default font size...

Thanks, Neil.

[ Why does my pass rule not work. ]

The way you have your variables set the alert rule picks up traffic
from any port, anywhere, to any port on your home net.  The source
address of the alert is 10.27.13.211, which matches "anywhere," and
the target address is 10.27.255.255, which matches "10.27.0.0/16".

Your pass rule affects traffic moving between 10.47.0.0./16 and your
home net -- note the second octet is "47", not "27" ( typo?).  That's
why the pass rule isn't doing what you want.

I hope this helps.
