UDP ports >1024

[ontrack]

My internet perimeter router has an access list that permits traffic inbound destined for UDP ports greater than 1024. From what I can tell this is needed for web browsing. Does anyone have any knowledge as to why web browsing needs UDP ports greater than 1024 to be open?

The tcp is setup on port 80 and return traffic can be on a high random udp port. If you are looking to protect your network use a firewall with context based access controls. Access lists are not sufficient.
