# ROUTING

Routing can be configured in three sections:

- Static route: Enables the definition of static routes. Static routing represents a set of rules defined by the administrator as well as a default route.
- Bird dynamic routing: Allows configuring dynamic routing protocols (RIP, OSPF, BGP) in a Bird engine, in order to allow the firewall to learn routes managed by other appliances.
- Return routes: when several gateways are used for load balancing, this tab will allow defining the gateway through which return packets will need to go in order to guarantee the consistence of connections.

These segments operate simultaneously, static routing having priority over all the rest during the transmission of a packet over the network.
