|
| Service) protection. By default, when the firewall is activated, all |
|
| incoming traffic from the WAN to the LAN is blocked unless it is |
|
| initiated from the LAN. The firewall supports TCP/UDP inspection, |
|
| DoS detection and prevention, real time alerts, reports and logs. |

| URL Filtering | URL filtering allows you to block access to Internet web sites of |
|
| certain URL that you specify. |

|
| on the LAN, which see only Ethernet and are not aware of PPPoE |
|
| thus saving you from having to manage PPPoE clients on individual |
|
| computers. |
