Yes, and perhaps in addition to scanning a node past the firewall, also
scan the firewall itself.

Some firewalls have ports open for various management/proxy/security
functions so you want to make sure you have open only what you need &
know about on the firewall itself.

Sometimes they are not covered by the policy, sometimes they are.
