Existing LAN broadband router how to configure multiple

there are multiple LAN broadband router broadband router how to configure the user contact, probably are aware of the port broadband router with WAN port and LAN port of the points. In the course of broadband routers have this feature: From LAN to WAN direction of data flow unrestricted through the router by default, from the default WAN to LAN direction can not be passed. (Note: The wireless broadband router wireless access part of the scope of subordinate LAN) that is, by default, the computer from the LAN packets sent into the router's LAN port, can go through the router from the WAN port to be issued, but from WAN active over the side into the WAN port after the data packet, the router default is to keep those data packets to pass.
This document describes the LAN memory when more than one broadband router's configuration (This document to a wired router TL-R460 + and wireless router TL-WR541G + as an example.)
First, network topology analysis
1, suppose you have an ADSL broadband line, through the TL-R460 + broadband router to achieve the two computers to share Internet access, network connection diagram is as follows:
broadband lines <-> ADSL MODEM <-> (WAN port) R460 + (LAN port) <-> PC
2, for some reason, you purchase a TL-WR541G + wireless broadband router, you want the network to provide wireless access capabilities, this time must be from the TL-R460 +'s LAN port leads to a network cable TL-WR541G +, you should connect the WAN port WR541G + it? Or the LAN port link WR541G +? There are two network connection diagram:
1) broadband line <-> ADSL MODEM <-> R460 + (LAN port )<->( WAN port) WR541G + (wireless) <-> PC
In this connection methods, as long as you can set as follows:
first IP address of the computer 2 is configured to 192.168.1.X (X taking natural numbers range 2-254), by 172.16.1.1 ( Note: This address can be changed and the original address any internal network segments of different address), save prompt to restart the router.
the next IP address of the computer and then modify 172.16.1.X (X taking natural numbers range from 2 to 254), as shown below:


again by
IP Address: 192.168.1.X (X taking natural number range 2 ~ 254)
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.1.1
Note: The router is connected in this manner following R460 + the computer can not WR541G + the following visits the computer through the Network Neighborhood.
2) broadband lines <-> ADSL MODEM <-> R460 + (LAN port )<->( LAN port) WR541G + (wireless) <-> PC
do not use this connection as the WAN port so WR541G + there is no need to configure the WAN port, and only need to configure the following components:
First of all, you need to turn off the DHCP server function WR541G + (select
Second, change my WR541G +'s LAN port IP address (and the TL-R460 +'s LAN port addresses on the same network segment), such as to: 192.168.1.254, as long as the IP address is not used by other computers can.
next step is to connect through wireless or wired WR541G + and computers after configuring the above two steps, WR541G + is equivalent to a property to be consistent and R460 +! Equivalent to those computers directly connected to the R460 + LAN port following the computer, the computer's TCP / IP properties configuration parameters as shown below:


Through the above configuration, the network can achieve more than The following computers to share Internet access router.
