The centralized policy contains multiple component policies. Only one centralized policy can be activated globally at a time. To implement DIA we will configure the traffic data section of the centralized policy that will match traffic coming from 192.168.11.0/24 (LAN segment) to 15.15.15.10/32 (the webserver). We have removed the static route created in Step 2 (option 1), as the traffic will be directed by the centralized policy. Pro Inside global Inside local Outside local Outside global To check the list of translations, we can run the following command on the router: CSR01#show ip nat translations verbose Icmp_err_time 0, avc class stats 0x0, VPN id src 1, dst 0įigure 5.

CSR01#show policy-firewall sessions platform all We will display all sessions with 'all' keyword. It is possible to filter the output using one of the keywords above. V6-destination-address IPv6 Desination Address V4-destination-address IPv4 Desination Address To view active sessions using CLI as they are passing, use show policy-firewall sessions command: CSR01#show policy-firewall sessions platform ?

The class map that follows uses the ACL as a “match” condition.įinally, policy-map now has a custom class-map statement placed above the default. Then access list is defined using the object groups. The first three commands are object groups that identify the source, destination, and protocol. VManage sends the following commands to the device. Review the rule, save it, and its parent firewall policy. The test shows that the ICMP traffic is blocked as soon as the policy is applied.
Zone-pair security ZP_VPN1_VPN0_VPN1-to-VPN0 source VPN1 destination VPN0 The ‘inspect’ firewall policy is defined and applied within the zone-pair configuration block. As we haven’t specified any specific rules, the policy uses only the class-default class with drop action. The listing below shows the config lines are sent to the device based on the configuration we’ve made so far (you can check this via configuration difference preview before the configuration push). And press the Update button to push the configuration to the device. Choose ISR1-Security-Policy in the Security Policy dropdown.
