Options Respond to ICMP Allow IPSec Allow PPTP Allow L2TP Advanced Administration The ICMP protocol is used by the "ping" and "traceroute" programs, and by network monitoring and diagnostic programs. • If checked, the Wireless Router will respond to ICMP packets received from the Internet. • If not checked, ICMP packets from the Internet will be ignored. Disabling this option provides a slight increase in security. The IPSec protocol is used to establish a secure connection, and is widely used by VPN (Virtual Private Networking) programs. • If checked, IPSec connections are allowed. • If not checked, IPSec connections are blocked. PPTP (Point to Point Tunneling Protocol) is widely used by VPN (Virtual Private Networking) programs. • If checked, PPTP connections are allowed. • If not checked, PPTP connections are blocked. L2TP is a protocol developed by Cisco for VPNs (Virtual Private Networks). • If checked, L2TP connections are allowed. • If not checked, L2TP connections are blocked. 85
