The first packet arrives on $int_if and is blocked by "block in all". 
It never has a chance to route to $ext_if, and thus never matches the
nat rule.  The "nat pass" does not apply because the initial packet is
not arriving on $ext_if so it can't match the rule (yet).

You have to allow the connection in on $int_if first, then when it
routes out $ext_if it will match the nat rule and set up state.
