Gateway—How to Configure Static Routes

MIME Flood Attack Check

A MIME flood attack uses an improperly formatted MIME header in “sendmail” to cause a buffer overflow on the destination host.

Use the Max Header Length field to set the maximum allowable header length. Set this value to be at least 256 bytes.

Use the Max Headers field to set the maximum number of headers allowed. Set this value to be at least 12.

Gateway—How to Configure Static Routes

A router uses routing tables and protocols to forward data packets from one network to another. The switch’s router manages traffic within the switch’s network, and directs traffic from the WAN to destinations on the switch-managed LAN. The WS 2000 Network Management System provides the Router screen to view and set the router’s connected routes. To view this screen, select Network Configuration --> Router from the menu on the left.

The Connected Routes area of the screen displays a list of currently connected routes between the enabled subnets, the WAN, and the router. The information here is generated from settings applied on the Subnet and WAN screens. The destination for each subnet is its IP address. The subnet mask (or network mask) and gateway settings are those belonging to each subnet, or to the WAN in general. If multiple IP addresses are associated with WAN communications, all the address will be displayed in the Connected Routes are of the screen. Also listed here is the default route, which specifies the WAN gateway IP address. To make changes to the information in the Connected Routes information, go to the appropriate subnet screen (LAN --> <subnet name> or the WAN screen (WAN).
