acl Safe_ports port 1025-65535 # unregistered ports
acl Safe_ports port 280 # http-mgmt
acl Safe_ports port 488 # gss-http
acl Safe_ports port 591 # filemaker
acl Safe_ports port 777 # multiling http
acl CONNECT method CONNECT
Below declare parameter :
http_access deny !Safe_ports (all port will denied for access except acl name "safe_ports", argument "!" as exception) - ACL Mac Address Below sample paramater and argument
acl block_mac arp 01:23:45:AB:CD:EF
http_access deny block_mac - ACL by IP Address
