Huawei EchoLife BM626 BM625 WiMAX Modem - DNS Hack

BM626 & BM625 are preventing client pcs to use their own dns server, and redirect all dns queries to he router default dns server, which is something bothering us all.

Therefore, follow these steps to configure your own DNS settings:

Using cat command

1. make sure you have telnet (or putty) and the Lan access is selected from Advanced > ACL in the router web configuration page.
2. login to the router 192.168.1.1 using wimax:wimax820 (make sure to choose telnet in putty)
3. type sh
4. type cd etc
5. type cat resolv.conf, and remember the output
6. type cat > resolv.conf, in the new line type nameserver 8.8.8.8
7. click ctrl+j for new line, then ctrl+d for exit
8. type cat resolv.conf, to check if the dns has changed.
9. type in the command prompt ipconfig /flushdns to delete the cached dns and activate the new one

Using TFTP Server

1. download TFTP server, you can try SolarWinds'
2. install it then run it
3. click on Configure, then click Browse and choose a valid folder, and remember your choice
4. disable your firewall (or you can open a UDP port no 69)
5. type ctrl+r, then type cmd then OK (make sure you have telnet in your pc or you can use putty)
6. type telent 192.168.1.1 (the IP of your router)
7. for the Login type wimax, and for password type wimax820
8. type sh then enter
9. type cd etc
10. type tftp -s -l resolv.conf 192.168.1.xx (xx change it with your pc IP)
11. browse to the TFTP folder which you chose, and text edit the file resolv.conf
12. change the IP Number after the word nameserver to what ever DNS you like (let's choose google 8.8.8.8 and 8.8.4.4)
13. save and exit
14. go back to the command prompt, and type tftp -g -r resolv.conf 192.168.1.xx (xx change it with your pc IP)
15. type in the command prompt ipconfig /flushdns to delete the cached dns and activate the new one
