Sure sounds to me like you're blocking traffic to/from your gateway. I
assume you've studied your logs? All of your block rules appear to be
logging, so I'm not sure why we haven't seen any mention of what might
be (or might not be) appearing in your log.
Run "tcpdump -nettti pflog0" as you run your ping tests. That will tell
you which rule is causing your headache. Then run "pfctl -s rules |grep <rule #>" to find out which one it is.
Honestly, your ruleset is giving *me* headaches just looking at it.
Your background with Linux (that's not a rip; hell, I'm an rhce)
certainly shows. Try to avoid the default behavior towards quick unless
you're really sure that's what you want. You don't need to worry about
performance... skip steps really avoids the extra processing overhead.
