Static Routing

If the Gateway is connected to more than one network, it may be necessary to set up a static route between them.

Astatic route is a pre-determined pathway that network information must travel to reach a specific host or network. To create a static route, change the following settings:

•• Select Set Number  Select the number of the static route from the drop-down menu. The Gateway supports up to 20 static route entries. If you need to delete a route, after selecting the entry, click Delete

This Entry.

•• Destination IP Address  The Destination IP Address is the address of the remote network or host to which you want to assign a static route. Enter the IP address of the host for which you wish to create a static route. If you are building a route to an entire network, be sure that the network portion of the IP address is set to 0.

•• Subnet Mask  The Subnet Mask determines which portion of a Destination IP address is the network portion, and which portion is the host portion.

•• Gateway  This is the IP address of the gateway device that allows for contact between the Adapter and the remote network or host.

•• Hop Count  This is the number of hops to each node until the destination is reached (16 hops maximum). Enter the Hop Count in this field.

Show Routing Table  Click Show Routing Table to open a screen displaying how data is routed through your local network. For each route, the Destination IP address, Subnet Mask, Gateway, and Interface are displayed. Click Refresh to update the information. Click Close to return to the previous screen.

Filter Cookies  A cookie is data stored on your computer and used by Internet sites when you interact with them. To enable cookie filtering, click Enabled.

Filter Java Applets  Java is a programming language for websites. If you deny Java Applets, you run the risk of not having access to Internet sites created using this programming language. To enable Java Applet filtering, click Enabled.

Filter ActiveX  ActiveX is a programming language for websites. If you deny ActiveX, you run the risk of not having access to Internet sites created using this programming language. To enable ActiveX filtering, click Enabled.

Block WAN Requests

Block Anonymous Internet Requests  When enabled, this feature keeps your network from being “pinged,” or detected, by other Internet users. It also hides your network ports. Both make it more difficult for outside users to enter your network. This filter is enabled by default. Select Disabled to allow anonymous Internet requests.
