Have you also added rules for allowing return traffic? Because that will be originating from the opt1 to the internet. Not entirely sure on bridges as I don't use them a lot (once actually). But iirc you need to add firewall rules on the opt1 interface as well. The firewall logs should normally provide you with the relevant info on blocking. You can also tag a rule to log to see if it's matching ofcourse. Regards, Seth
