■ Respond to ICMP (ping) on WAN interface - If enabled, your router
responds to pings from sources on the Internet. Not enabling this
option provides a slight increase in security.

a protocol used for VPN (Virtual Private Networking) connections to
increase security.

Tunneling Protocol) connections. PPTP is a protocol used for VPN
(Virtual Private Networking) connections to increase security.

developed by Cisco) connections. L2TP is a protocol used for VPN
(Virtual Private Networking) connections to increase security.
