On a Cisco router first create the access list which would look something like the following (issued in config mode) :
access-list 101 deny tcp any any eq 80
access-list 101 permit ip any any
Next apply to the correct interface (must be in config-if mode) as an inbound or outbound access list using one of the following commands:
ip access-group 101 out
ip access-group 101 in
Make sure you test any and all access lists before putting them in to production. If you enter the wrong thing it can shut your network down so proceed with caution and at your own risk.</b>
