Parameter Description
Miscellaneous
NAT
If the switch is moved to the right, the network address translation
function is enabled. Do not disable the function unless your ISP
requires this.
Firewall
If the switch is moved to the right, protection against external
connections for the LAN devices is enabled (for example, against
attempts to get information about the LAN devices or to hack a
device from the LAN). For security reasons, it is recommended not
to disable this function.
Ping
If the switch is moved to the right, the router responds to ping
requests from the external network through this connection. For
security reasons, it is recommended to disable this function.
Isolate connection
If the switch is moved to the right, the router uses an alternate
routing table for this connection. Enable this function only when
your ISP requires this.
When all needed settings are configured, click the APPLY button.
