How-To TP-LINK WR740N Openwrt MultiWAN

Just wanted to share my TP-Link WR740N ver4.27 wireless router flashed with Openwrt firmware "Attitude Adjustment 12.0" loaded with MultiWAN. These are five (5) ADSL trunk that I wanted to do with load balancing likewise as failover. My equipment compose of one (1) TP-Link WR740N wireless router use as the core, one Azetech ADSL modem with four(4) port LAN, one (1)port RJ11 built-in with wireless Access Point were I used as WISP server. Also I have four(4) TP-Link ADSL modem TD-8816 were I used as routed device for eWAN1-4.

As you can see the above network diagram how I wired all the device to make it work properly, I have five(5) xDSL line hooked to each of the TP-Link TD-8816 then to WR740N wireless router four(4) LAN port but converted it as eWAN port via Free Switch of Openwrt plugins. Now my WR740N flashed with OpenWrt firmware will serve as load balancer and failover appliances.

So, here's my setup of TP-Link WR740N flashed with OpenWrt Attitude Adjustment 12.09 as Load Balancer and Failover. First what I did is configure the VLAN Switch.

By default after the TP-Link WR740N flashed with OpenWrt firmware this is how it looks like, then proceed to configure the VLAN Switch make at least four VLANs.

After successfully able to configure the VLANs Switch, then proceed to setup for the eWANs.

The above screenshot having five(5) xDSL trunk, four(4) lines are via TP-Link TD-8816, then the other line is via WISP server, my Azetech modem router that has built-in Access Point aka WiFi I made it in Bridge Mode then also serve as PPPoE server. Then configure the TP-Link WR740N WLAN or radio0 as client mode and connect to the WISP server that is why I have able to made it work as five xDSL trunk. Forget to mention that I revert that eth0 by default is for LAN convert it to WAN then likewise the eth1 by default is for WAN convert it to LAN.

The last but not the least, please don't forget the firewall setting because fail to do this things your internet will not work inshort you will not be able to browse any of your favorite website. This part here is a must, you can just follow my screenshot and edit the setting if how many trunks you have with you.

Finally the MultiWAN Openwrt plugins will just turn into green as above sample you, your TP-Link WR740N now doing the job as Load Balancer and Failover, just like those expensive Cisco equipment, D-Link not to mention others... enjoy!

TM Riger DB120-WL reflash with TD-W8951ND Stock Firmware

If you are unhappy of your Riger DB120-WL Streamyx residential modem wireless router because of its buggy stock firmware given by TM for you as FREE, now you are not anymore locked by your ISP you will now have the chance to re-flashing your device with the TP-Link TD-W8951ND v5 third party stock firmware that will give you the total freedom.

Before you proceed, take this precaution.

• This applicable only Riger DB120-WL (Silver) with Firmware Riger v4 installed by default.
• Before you proceed updating, please connect your PC directly via LAN cable to DB120-WL
• This may void your warranty (may or may not be, since you didn't open the case)
• Doing this is at your own risk!

Step 1. Download Firmware

• Download TP-LINK TD-W8951ND v5 firmware from TP-Link Websites

Step 2. Extract

• Open zip file and then open "TD-W8951ND_V5_140226 & TD-W8951ND_V5_140306" folder, extract "TD-W8951_V5_140306" folder (simply click once and drag)

Step 3. Login

• Note: Do this only when computer connected via LAN Cable (Hardwired)
• Username: tmadmin
• Password: Adm@**** (**** is the last 4 HEX digit of MAC Address, eg: D1E3 => Adm@D1E3, you can find bottom of your DB120-WL)

Step 4. Click maintenance

• After successful login, click maintenance and then click Firmware, until you see this page:

Step 5. Choose firmware

• Click New Firmware Location: "Browse" button and then locate back where you extract just now, and then open that folder and choose "ras" file.

Step 6. Proceed!

• Click "UPGRADE" button! and wait until you see a progress bar!

Step 7. Update complete

• Once progress bar reach 100% and it will redirect to new TP-Link login page!
• Please login using previous username and password (it's look awkward when login using tmadmin under TP-Link page, lol)

Step 8. Finished!

• Well done, now you have working DB120-WL with TP-Link Firmware! TP-Link will use your previous configuration.

Step 9. Improve Wireless Security

• Click Interface Setup tab and then click Wireless
• Scroll down until you find Multiple SSID Settings, change SSID Index to 2.
• Change SSID: Riger1 to any string you like,
• Then change encryption to WPA2-PSK and put any password you like.
• Repeat until SSID Index: 4
• This simply blocking from someone using your hidden wireless, because default DB120-WL allow other to join your wireless freely by simply enter "Riger1" or "Riger2" or "Riger3" SSID.

Jetway J7F2 Four LAN Mini-ITX for pfSense

For quite a while I was running m0n0wall on an old dell laptop with two NICs. This worked out pretty well because the laptop had a built-in screen, keyboard, and battery backup of sorts. It was also fairly portable. At some point I decided I wanted to do a bit more with my firewall and move to more powerful hardware. In particular, I wanted to try out pfSense, a m0n0wall fork. pfSense contains a package management system that allows you to install a wide variety of services including: Snort, Squid, FreeSWITCH, OpenBGPD, to name a few. I'll return to these in subsequent posts. I also needed more interfaces to be able to properly segregate my wireless network from my wired network.

I've been a big fan of the smaller form factor x86 machines for a while. Serapeum was built on a MicroATX form factor as well as my current desktop system. µATX is great for smaller desktop machines but is a bit too large for a firewall solution.

Mini-ITX seemed like the perfect option. I selected the Jetway J7F2 board with a 1.5Ghz Via C7 processor. Two compelling reasons for selecting this board were the Padlock engine, which provides hardware RNG, AES, and hashing acceleration, and support for daughter cards. Some quick OpenSSL benchmarks using the various engines provided these results:

cryptodev kilobytes per second:

type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes

aes-256-cbc 10166.19k 10492.00k 10832.45k 10520.09k 10871.68k

padlock kilobytes per second:

type 16 bytes 64 bytes 256 bytes 1024 bytes 8192 bytes

aes-256-cbc 69552.53k 221044.97k 475699.68k 662806.69k 745178.49k

The padlock hardware engine provides a 6850% increase in AES 256 encryption over the software based cryptodev. It peeks at about 5.7 gigabits per second. Cryptodev only achieves 85 megabits per second.

Summary of build hardware:
Jetway J7F2 VIA C7 1.5Ghz
Jetway AD3RTLANG 3 port GigaLAN daughter card
Corsair 1GB DDR2 533
Transcend 4GB CF 300x
M200 Enclosure
PicoPSU-120
