Note on OpenWRT on TP-LINK TL-WR703N

Notes On Installation

This is some notes, used to install and get relayd up and running. I may use it as a plan open wireless access point in the future.

Download:

$ wget http://downloads.openwrt.org/attitude_adjustment/12.09/ar71xx/generic/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin

Set laptop wired IP to 192.168.1.4

Follow the instructions at http://www.madox.net/blog/projects/tp-link-tl-wr703n/

Still in the browser, login to router (root/blank). Set password.

Now I am also running openWRT on my main home wireless access point. Using 192.168.1.1, so once the router is flashed I need to change the routers fixed LAN address to something else - if I want to connect to my main wireless access point.

Still in the browser, at http://192.168.1.1/ -> Network Edit LAN, set IPv4 address -> 192.168.2.1 -> Save and apply

You are now unable to connect, change laptop wired IP Address to 192.168.2.4, Netmask as 255.255.255.0, Gateway as 192.168.2.1, DNS Servers as 192.168.2.1

Browser go to http://192.168.2.1/ redirect to http://192.168.2.1/cgi-bin/luci

Network -> Wifi -> Scan

Then (hopefully) Join Network for the network of your choice. Enter key and leave Create / Assign firewall-zone as WAN -> Save & Apply -> Interfaces

And we should see a nice IPv4 for the WAN side as well, time for some command line on the router, to confirm connection:

$ ssh root@192.168.2.1
root@OpenWrt:~# ping google.com
root@OpenWrt:~# opkg update
root@OpenWrt:~# opkg install relayd
root@OpenWrt:~# opkg install luci-proto-relay
root@OpenWrt:~# /etc/init.d/relayd enable

Back/Still in the browser, Network -> Create Interface, Named: stabridge Protocol: Relay Bridge, Then tick WAN and LAN, Local IPv4 address: 192.168.2.1, Save and Apply

Network -> Firewall -> General Settings Zone Forwarding, Lan=>Wan - Change forwarding to Accept

Back to laptop and try:

$ ping google
