If you install Symantec Gateway Security 300 Series appliances on a network
with more than one directly connected router, you must specify to which router
to send traffic. The appliance supports two types of routing: dynamic and static.
Dynamic routing chooses the best route for packets and sends the packets to the
appropriate router. Static routing sends packets to the router you specify.
Routing information is maintained in a routing table.
Dynamic routing is administered using the RIP v2 protocol. When it is enabled,
the appliance listens and sends RIP requests on both the internal (LAN) and
external (WAN) interfaces. RIP v2 updates the routing table based on
information from untrusted sources, so you should only use dynamic routing for
intranet or department gateways where you can rely on trusted routing updates.
Routing helps the flow of traffic when you have multiple routers on a network.
Configure dynamic or static routing to fit your needs.
You do not need routing information to use dynamic routing.
