For typical firewall settings, users could configure the following options on the UCM6200.
Table 13: Typical Firewall Settings
Ping Defense
Enable
If enabled, ICMP response will not be allowed for Ping request. The default
setting is disabled. To enable or disable it, click on the check box for the LAN or
WAN (UCM6200) interface.
SYN-Flood
Defense Enable
Allows the UCM6200 to handle excessive amounts of SYN packets from one
source and keep the web portal accessible. There are two options available and
only one of these options may be enabled at one time.
• eth(0)LAN defends against attacks directed to the LAN IP address of the
UCM6200.
• eth(1)WAN defends against attacks directed to the WAN IP address of the
UCM6200.
SYN Flood Defense will limit the amount of SYN packets accepted by the UCM
from one source to 10 packets per second. Any excess packets from that source
will be discarded.
