Chapter 4 Configure the Router in Wireless Router Mode 1 ) Enter the MAC address (in XX-XX-XX-XX-XX-XX format.) of the client for which you want to reserve an IP address. 2 ) Enter the IP address (in dotted-decimal notation) which you want to reserve for the client. 3 ) Leave the Status as Enabled. 4 ) Click Save. 4. 9. Forwarding The router's NAT (Network Address Translation) feature makes the devices on the LAN use the same public IP address to communicate in the internet, which protects the local network by hiding IP addresses of the devices. However, it also brings about the problem that external hosts cannot initiatively communicate with the specified devices in the local network. With the forwarding feature, the router can traverse the isolation of NAT so that clients on the internet can reach devices on the LAN and realize some specific functions. The TP-Link router includes four forwarding rules. If two or more rules are set, the priority of implementation from high to low is Virtual Servers, Port Triggering, UPNP and DMZ. 4. 9. 1. Virtual Server When you build up a server in the local network and want to share it on the internet, Virtual Servers can realize the service and provide it to internet users. At the same time virtual servers can keep the local network safe as other services are still invisible from the internet. Virtual Servers can be used to set up public services in your local network, such as HTTP, FTP, DNS, POP3/SMTP and Telnet. Different service uses different service port. Port 80 is used in HTTP service, port 21 in FTP service, port 25 in SMTP service and port 110 in POP3 service. Please verify the service port number before the configuration. 35

Virtual Server
When you build up a server in the local network and want to share it on the internet,
Virtual Servers can realize the service and provide it to internet users. At the same time
virtual servers can keep the local network safe as other services are still invisible from
the internet.
Virtual Servers can be used to set up public services in your local network, such as
HTTP, FTP, DNS, POP3/SMTP and Telnet. Different service uses different service port.
Port 80 is used in HTTP service, port 21 in FTP service, port 25 in SMTP service and port
