I've attached a partially sanitized concatenation of pf rules, ifconfig,
netstat -nr, cat /etc/hostname.$if. Please let me know what more info would be
helpful.
FWIW, this firewall has been operating successfully with snaps for many years.
The pf configuration is not tuned as it is somewhat a testbed with an
accumulation of various failed/successful experiments. Also, the urtwn
interface has been removed for at least the past month so treat the associated
rules accordingly.
