5 In the text box, type a text string that is an exact, case-sensitive match to the authentication string
transmitted by the RIP server.

authentication string encrypted with MD5.

Changing from Dynamic Routing to Static Routing
Before you change from dynamic routing to static routing, you may want to save your dynamic routes to
the static route table. Selecting this option saves the current RIP dynamic routing information as static
routes.
If you change from dynamic routing to static routing, and you previously created static routes, the static
routes reappear in the Firebox SSL VPN Gateway routing table.
If these static routes are no longer valid, or if no static routes were created previously, you might lose
remote access to the Administration Tool and users could lose access to the internal network resources
until you manually configure the static routes.
Saving the current RIP dynamic routing information as static routes when you switch from dynamic
routing to static routing allows you to maintain connectivity until you properly configure the static
routes.
To save dynamic routes to the static route table
1 On the Firebox SSL VPN Gateway Cluster tab, open the window for the appliance.
2 Click the Routes tab.
3 Click Save to static routes .
After you save the dynamic route, you can switch to static routing.
Configuring a Static Route
When setting up communication with another host or network, a static route might need to be added
from the Firebox SSL VPN Gateway to the new destination if you do not use dynamic routing.
Set up static routes on the Firebox SSL VPN Gateway adapter not being used by the Default Gateway
that is specified on the
General Networking tab.
For an example static route setup, see “Static Route Example” on page 54.
To add a static route
1 Click the VPN Gateway Cluster tab and then click the Routes tab.
2 In Select routing type , select Static Routing .
3 Under Add Static Route , in Destination LAN IP Address , type the IP address of the destination
local area network.
4 In Subnet Mask , type the subnet mask for the gateway device.
5 In Gateway , type the IP address for the default gateway. If you do not specify a gateway, the Firebox
SSL VPN Gateway can access content only on the local network.
6 In Interface , select the network adapter for the static route. The default is eth0.
7 Click Add Static Route .
