Basic Firewall
The Web Content Filter page has various settings related to blocking or exclusively allowing different
types of data through the CMRG from the WAN to the LAN. There are three security firewall protection
levels (low, medium, and high) which correspond to the number of services allowed.

packets prevents all fragmented IP packets from passing through the firewall. Port Scan Detection
detects and blocks port scan activity originating on both the LAN and WAN. IP Flood Detection detects
and blocks packet floods originating on both the LAN and WAN.
