Version 1.0.20.31
Table 11: UCM6510 Security SettingsStatic DefenseCurrent Service
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.
Table 12: Typical Firewall Settings
If enabled, the UCM will not send ICMP messages in response to ping requests.
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
inaccessible. Excess packets will be discarded.
There is no need to mention the WAN and LAN parts since it is already
mentioned in sentence before the table.
Ping-of-Death
Defense Enable
If enabled, the UCM will not be affected by ping of death attacks.
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.
