11.2 Security Setting
The "Security Setting" page allows the administrator to manage the firewall.
FIREWALL SECURITY
This section lists all the available security settings.
UPnP Support: Enables or disables the "UPnP Support" feature. Enable this
feature if you would like to support the Universal Plug and Play (UPnP) protocol.
Response to Ping: Enables or disables the "Response to Ping" feature. Enable
this feature to make the UMG-2000 / UMG-2200 respond to the ping request from
the Internet.
TCP SYN Cookie: Enables or disables the "TCP SYNC Cookie" feature. Enabling
this feature will enable the SYN cookie to protect partial SYN-flood DoS attacks.
DMZ Server Address: Specifies the DMZ host IP address. The clients on the
outside network cannot connect to the servers in the private network which are
protected by the firewall. To solve this problem, a DMZ (demilitarized zone) host
is inserted between the company's private network and the public network. The
DMZ host will be exposed to the Internet without protection. Specify it only if
you need a special Internet service or expose one computer with no restriction.
