From this diagram, it appears that packet filter rules to operate on
outbound packets before NAT and inbound packets after NAT.

As your firewall is set to default pass, the outbound packets didn't
match any of your rules but were passed without maintaining any
state information and the inbound packets wouldn't have an existing
entry to match.

I would add a rule which would pass outbound packets from your
internal system to any.

When snooping for the traffic on the outside, was the outbound
traffic properly NAT'ed?

Additionally, the lack of active sessions or host mappings from
ipnat -slv seems odd.
