This is normal HTTP traffic. I suspect if you add keep state to the last two
rules you shouldn't need the first two.

Again - add keep state to the second two rules and I think it should suffice
for the first two rules.

Same thing here. Looks like it wants to make outgoing connections on 80,
443, and 29900. Nothing terribly unusual about that.
