I added this for a temporary fix:
${fwcmd} add pass all from any to any
I don't think that is the right answer; That allows to much in?
Yes.
I've tried these per the docs:
${fwcmd} add allow all from any to any out via {$iip} setup
${fwcmd} add allow all from any to any out via {$iip} established
${fwcmd} add allow all from any to any in via {$iip} established
and also a bunch of others; but none of them worked.
Try oip instead of iip. iip is your internal IP address, so anything
going out from iip is going to your lan, and anything coming in to iip
is coming from your lan. You want to control packets communicating with
the outside world, so you want to control them at oip.
Sorry, that didn't work.
I also tried this:
${fwcmd} add allow tcp from any to any via ${oip} setup
${fwcmd} add allow udp from any to any via ${oip} setup
${fwcmd} add allow tcp from any to any via ${oip} established
${fwcmd} add allow udp from any to any via ${oip} established
That also blocks it. :(
Even tried this and still doesn't work.
${fwcmd} add allow tcp from any to any via ${oip}
${fwcmd} add allow udp from any to any via ${oip}
Grrr, this doesn't work either:
# statefull
${fwcmd} add check-state
${fwcmd} add allow tcp from any to any established
${fwcmd} add allow all from any to any out keep-state
${fwcmd} add allow icmp from any to any
This thread talks about the same problem:

"You will most likely find that dynamic rules will allow this
ingress traffic, without the need to explicitly allow it."
But unfortunately there is no follow up reply in that archive.
