PF blocking even if set to pass all

[Alaor Barroso de Carvalho Neto]

Hi guyz, like I've said in other topic, I'm building a BSD box that'll act
as a gateway between three private networks and the internet. I want that
each private network can ping to each other, and I can do that till I
activate my pf firewall. When I do pfctl -e it stop working.

The output of pfctl -sr is:
pass in all
pass out all

So I guess it would pass anything, why it isn't happening?

Hugs,
Alaor
