Example 2: Single Mode Firewall Using Same Security Level
Example 2: Single Mode Firewall Using Same Security Level
This configuration creates three internal interfaces. Two of the interfaces connect to departments that are
on the same security level, which allows all hosts to communicate without using access lists. The DMZ
interface hosts a syslog server. The management host on the outside needs access to the Syslog server
and the security appliance. To connect to the security appliance, the host uses a VPN connection. The
security appliance uses RIP on the inside interfaces to learn routes. The security appliance does not
advertise routes with RIP; the upstream router needs to use static routes for security appliance traffic
(see
Figure B-2 ).
The Department networks are allowed to access the Internet, and use PAT.
