Could you change your last rule to this:

block in log quick on xl0 all

and then tell what you see in the log. This would give some information 
if any traffic is blocked in the first place. Actually, adding the log 
keyword to all rules for the xl0 interface might be a good idea for 

Also, is this the complete ruleset or did you remove rules you thought 
were irrelevant? If so, then post the whole ruleset.

Cheers, Erik
