!---Configure the firewall interface that connects to the branch office PCs
!---and the Firewall Websense UFS:
!---Apply access lists and inspection rules to control access to the interface.
!---In this example, access list 116 is used to filter outbound packets, and
!---the inspection rule named “myfw” is used to filter inbound packets.
!---Enable the authentication proxy rule for dynamic, per-user authentication
!---and authorization. See the previous “aaa authorization auth-proxy default group SJ”
!---and “ip auth-proxy name aprule http” command entries.
!---Apply the Cisco IPS rule to outbound traffic.
interface FastEthernet0/0
ip address 192.168.1.2 255.255.255.0
ip access-group 116 out
ip inspect myfw in
ip auth-proxy aprule
ip ips ids-policy out

!---Configure the interface that connects to the
!---Cisco Secure Authentication Control Server (Cisco Secure ACS).
!---Apply access lists to control access to the interface.
!---In this example, access list 111 is used to filter inbound packets.
interface FastEthernet0/1
ip address 192.168.101.2 255.255.255.0
ip access-group 111 in
.

ip classless
!---The following command establishes a static route to the HTTP server,
!---which in this example has an IP address of 192.168.102.119.
ip route 192.168.102.0 255.255.255.0 FastEthernet0/1
!
!---Enable the HTTP server on your system.
!---Also, specify that the authentication method used for AAA login service
!---should be used for authenticating HTTP server users.
ip http server
ip http authentication aaa
no ip http secure-server

!---Configure the access list for the interface that connects to the
!---Cisco Secure ACS.
