Pass all protocols in PF

[Erik Osterholm]

I've been working with PF for awhile, and this is something that's
bugged me for some time.  Is there any way to make "pass in all" pass
any protocol?  Right now, for example, we have a firewall with two
bridged (if_bridge) Intel NICs and pf.  We need OSPF to pass, and
so we have to add an explicit rule to pass it, despite the fact that
we have a default pass in any rule.  It's the same story for other
protocols.

Thanks in advance for any replies.
