Secure Multimedia Controller Implementation Guide
SMC be brought into service and utilized for a period of time in the unhooked
state to ensure all network issues have been resolved.
Procedure 24
Unhooking the firewall
1 Log on to the Web UI.
Note: This procedure cannot be performed using the CLI.
2 Navigate to the Multimedia Security > Security Settings > Status page.
3 Unhook the firewall.
4 In a high availability configuration, select the second SMC device from the
IP address drop-down list and unhook its firewall.
End of Procedure
Validating unhook
To validate that the firewalls are unhooked, view the firewall status on the
initial System page in the Web UI.
Note: You can add and update firewall rules while the firewall is
unhooked; however, the rules do not go into effect until the firewall is
reactivated (hooked).
IMPORTANT!
When the firewall is unhooked, all traffic flows through the SMC
unchecked or rate limited. Unhooking the firewall is recommended only
for initial installation and debugging purposes.
IMPORTANT!
If the firewall is hooked or unhooked while UNIStim security is enabled
and the IP phones are communicating through a proxied server, current
UNIStim sessions are disrupted. UNIStim communication re-establishes
and all existing calls drop. Insecure sessions—sessions that are not
currently running through the Secure UNIStim proxy—are not affected.
