Section 5.17.11
Managing Policies
Policies define the default actions for establishing a connection between different firewall zones. Each policy
consists of a source zone, a destination zone and an action to be performed when a connection request is
received.
The following example illustrates the policies for establishing connections between a local network and the
Internet.
Table: Example
Policy Source Zone Destination Zone Action
1 Loc Net ACCEPT
2 Net All DROP
3 All All REJECT
Each policy controls the connection between the source and destination zones. The first policy accepts all
connection requests from the local network to the Internet. The second policy drops or ignores all connection
requests from the Internet to any device on the network. The third policy rejects all other connection requests and
sends a TCP RST or an ICMP destination-unreachable packet to the client.
