Would you please specify why do you need a custom firmware on your router?
I'm asking because may be we can sort it out in someway without using custom firmware.
Firmwares are a bit hard to remove, install, upgrade and troubleshoot, better to avoid them as far as possible.

Always do some basic testing with the stock firmware in case it outperforms any custom firmware. You can always revert back to stock firmware, not always always but yea i meant that in a general way .i use the stock fw. see here (http://dd-wrt.com/phpBB2/viewtopic.php?p=359906&sid=ef6c2f755bd4675d7c8244bd8cf25719#359906). [/URL]I read that there is nothing to do besides finding the update firmware section of the airlink router page and flashing with [URL="http://www.dd-wrt.com/routerdb/de/download/Airlink 101/AR670W/-/airlink-factory-webflash.bin/3544"]airlink-factory-webflash.bin (http://dd-wrt.com/phpBB2/viewtopic.php?p=359906&sid=ef6c2f755bd4675d7c8244bd8cf25719#359906) and then ar670w-ddwrt-webflash.bin (http://www.dd-wrt.com/routerdb/de/download/Airlink 101/AR670W/-/ar670w-ddwrt-webflash.bin/3543)the following how to was posted by a user at dd-wrt forum:Starting with Airlink factory firmware, connect to the wireless network Go to dd-wrt website and download these 2 files to some folder on your computer: ar670w-ddwrt-webflash.bin airlink-factory-webflash.bin Now open up a web browser and put this into the address bar (assuming the standard Airlink settings): http://192.168.1.1 (http://192.168.1.1/) This is the webpage where you configure the router. It will ask for your login and password. Hopefully you know what your router password is. If it's new it could be something like username "admin" password "admin" or the password could be blank, or something. I don't remember, read the Airlink manual if you can't figure this part out. Once you are logged into the Airlink webpage you need to find the menu for firmware upgrade. One again, RTFM if you can't find this. I think it's under Administration or something. Anyway it will ask you for what file you want to use to update the firmware. Select the file you downloaded earlier named: airlink-factory-webflash.bin Then the update should begin. Wait about 3 minutes. After a few minutes you may notice you are no longer connected to your wireless network, because your old settings are gone with the old firmware. There should be a new wireless network appearing now, named "dd-wrt". Connect to it, you won't need a password. Once you are connected, put this into a web browser again: http://192.168.1.1 (http://192.168.1.1/) This gets you to the dd-wrt configuration page. It will give you some warning saying that you need to change the password. Do so. Once you are logged into the page, go click on the Administration tab, then UNDER that, the tab that says Firmware Upgrade. Now click the button that says "choose file" and select the file you downloaded earlier that is named: ar670w-ddwrt-webflash.bin Then click the Upgrade button. It will make you wait something like 5 minutes. Go ahead and wait, it's safest. After this time, you may or may not find yourself connected to the network named "dd-wrt". If not, connect to it. Then put this into the web browser: http://192.168.1.1 (http://192.168.1.1/) Log in with the administrator password you picked earlier and set up your stuff however you want. You now have your working DD-wrt ar670w, congrats, have fun, read the manual for how to set up all the settings---

Hi Airbander,
Come on boy! You're a natural born geek!:D
Yevgeny wrote a clear instructions on what you need to do.
But be aware that running a DNS which is accessible beyond a Lan is very dangerous. Why? Simply because anyone who can gain access to it, can shape or route specific traffic from your network to his side, ie. making Gmail or Banking records to route traffic to his Fake web servers, this type of attack can't be detected by normal users as there's nothing strange or suspicious in URL.
And did you know that a Remote Code Execution vulnerability (Means that an attacker can execute commands from remote with no need to correct credentials.) was found in DD-WRT? That was a public one and there are some vulnerabilities and exploits in the UG communities.
Anyway, I think you're gonna do it so please at least choose a strong password for your router. Last month a friend of mine wrote a simple script which checked an IP range for routers with admin-admin or other weak credentials, You know what we saw? more than 85% were that simple, 2 of them part of an enterprise network (Direct Internet Access for a Department. A bad design practice.)
P.S: I'm really worried about the running DNS without proper security measures and hardening, but that's me. Do what you believe is right.

Hello contemp,

You seem a very nice person and You care about others thanks for the advise. I am trying to keep the dns at local level away from WAN level
It is pretty difficult to do so i am reading on howto of it but so far very little success. I am just doing some testing at this moment to get it working so far no luck but i am learning new things lol

Thanks alot again
