For general firewall defense mechanisms, UCM supports Ping Defense, SYN-Flood Defense, and Ping-of-
Death Defense. These can be configured separately for the WAN interface and LAN interface.
Ping Defense
If enabled, the UCM will not send ICMP messages in response to ping requests.
Enable
If enabled, the UCM will limit the amount of SYN packets accepted from one
source to 10 packets per second, preventing the UCM web portal from becoming
SYN-Flood
inaccessible. Excess packets will be discarded.
Defense Enable
There is no need to mention the WAN and LAN parts since it is already
mentioned in sentence before the table.
Ping-of-Death
If enabled, the UCM will not be affected by ping of death attacks.
Defense Enable
In the Custom Firewall Settings section, users can create rules to accept, reject, or drop specific traffic
going through the UCM. To create a new rule, click on the [] button. To be consistent with the rest of the
manual, get an image of the actual "Create New Rule" button.
Select the connection type the rule will apply to.
