Example 5: Multiple Mode, Transparent Firewall with Outside Access Example
The following configuration creates three security contexts plus the admin context. Each context allows
OSPF traffic to pass between the inside and outside routers (see
Also, DHCP packets can pass through the transparent firewall, because the transparent firewall does not
support the DHCP relay feature.
Inside hosts can access the Internet through the outside, but no outside hosts can access the inside.
The admin context allows SSH sessions to the FWSM from one host. It also uses ARP inspection to
prevent IP spoofing of the upstream and downstream routers.
Each customer context belongs to a class that limits its resources (gold, silver, or bronze).
Although inside IP addresses can be the same across contexts, keeping them unique is easier to manage.
