DESCRIPTION
Select Enable to allow multicast traffic to pass through the ZyXEL Device. This
may affect your network performance.
Select Disable to prevent any multicast traffic from passing through the ZyXEL
Device. This is the default setting.
This feature affects the security of the ZyXEL Device's WAN port. Ping (Packet
INternet Groper) is a protocol that sends out ICMP echo requests to test
whether or not a remote host is reachable. Select Enable to have the ZyXEL
Device respond to incoming Ping requests from the WAN. This is less secure
since someone on the Internet can see that the ZyXEL Device is there by
pinging it.
Select Disable to have the ZyXEL Device not respond to incoming Ping
requests from the WAN. This is more secure since someone on the Internet
cannot see that the ZyXEL Device is there by pinging it.
Secure Socket Layer (SSL) security allows you to create secure connections
between the ZyXEL Device and the management or subscriber computer(s).
Select Default to use the default system-generated SSL certificate.
Select Customer Certificate to use a certificate obtained from a certificate
authority.
Refer to the SSL (Secure Socket Layer) Security chapter for more information.
Click Apply to save the changes.
