Planet VIP-161W [34/72] Virtual server setting for ap mode

Force (IETF) standard that combines the best features of two existing tunneling protocols: Cisco's

Layer 2 Forwarding (L2F) and Microsoft's Point-to-Point Tunneling Protocol (PPTP). L2TP is an

extension to the Point-to-Point Protocol (PPP), which is an important component for VPNs. VPNs allow

users and telecommuters to connect to their corporate intranets or extranets. Enable/Disable this

function.

SIP ALG：SIP, the Session Initiation Protocol, is a signaling protocol for Internet conferencing,

telephony, presence, events notification and instant messaging. Enable/Disable this protocol

verification.

DMZ：In computer networks, a DMZ (Demilitarized Zone) is a computer host or small network inserted

as a "neutral zone" between a company's private network and the outside public network. It prevents

outside users from getting direct access to a server that has company data. Think of DMZ as the front

yard of your house. It belongs to you and you may put some things there, but you would put anything

valuable inside the house where it can be properly secured. Setting up a DMZ is very easy. If you have

multiple computer s, you can choose to simply place one of the computers between the Internet

connection and the firewall.

DMZ LAN IP：If you have a computer that cannot run Internet applications properly from behind the

device, then you can allow the computer to have unrestricted Internet access. Enter the IP address of

that computer as a DMZ host with unrestricted Internet access. Adding a client to the DMZ may expose

that computer to a variety of security risks; so only use this option as a last resort.

Virtual Server setting (for AP mode)

The device can be configured as a virtual server so that remote users accessing services such as Web

or FTP services via the public (WAN) IP address can be automatically redirected to local servers in the

LAN network. Depending on the requested service (TCP/UDP port number), the device redirects the

external service request to the appropriate server within the LAN network. You will only need to input

the LAN IP address of the computer running the service and enable it.

A Virtual Server is defined as a service port, and all requests to this port will be redirected to the

computer specified by the server IP.
