Any cheap solution to limit bandwidth used by DMZ?

Any simple and cheap off-shelf box to achieve this goal?

You could find some commercial software too to shape the traffic.
The linksys router you have may not have bandwidth restriction feature. So, you should think of restriction on devices before the linksys router.
At this point I do not remember any switches or devices that you can put on your network to share the pipe. But I am pretty sure there are lots available in the market. I hope someone would name this featured enabled switch here which is cheap and easy installation.

What ever method you choose for sharing the bandwidth pipe you should consider that if your production unit not consuming the bandwidth then they are to be consumed all by your wifi client.

Thank you,

Hello richtree,

You didn't mention what Linksys router you're using. If it's for example a WRT54G, WRT54GS or WRT54GL running Linux you might want to install a firmware which does support bandwidth limiting like http://www.dd-wrt.com

*** Please note that installing a firmware like this will void warranty on your router and you will not receive technical support from Linksys anymore on your router, so you do this at your own risk ***

Hi LucF,
Your note is very interesting and brand new to me. Would you please post more details about which version I should download and how to flash it, etc. I am using Linksys WRT54G. I like to try it out, but a quickstart is appreciated.
Thanks.

Hi richtree,

Depending on the version of your WRT54G you might or might not be able to install such a firmware. At the chart at http://www.linksysinfo.org/forums/showthread.php?t=47282 you can see if yours is compatible.

Any version of the DD-WRT will do fine for bandwidth limiting, depending on the version the flash has to be performed in a different way so if you could mention the version of your WRT54G I'll probably be able to guide you through it.

Best regards,

Mine is Linksys WRT54G v6. Please post a quickstart for me please.

Hi LucF,
Thank you very much for your notes. I will try it out sometime and post the result here.

Sure, take your time and let me know if you need any additional information.

Hi LucF,
I am so excited to run Linux on WRT box! I got bandwidth control now! Thank you very much for your help.
Now one more question: is it possible to log the DHCP release either locally or to a syslog server? Right now I am interested in knowing how many wireless clients get address from this box. If feasible, please let know how to achieve it.
Thank you again.

Hi richtree,

I haven't tried the logging functionality of DD-WRT yet, I'll take a look to see if I can find anything for you.

LucF

Try also snmpwalk to the router and see if you find any OIDs or count the number of current leased. And you can use mrtg or prtg to poll the router to plot the dhcp lease report.

Hi LucF,
Can you provide me detail about your approach? I am not familiar with Linux.
Thanks a lot.

Thank you all for your help. I am really happy about the results. Now I enjoy advanced features while paying only a little money on the box. It is excellent!

Hi richtree,

Glad to help.
I found that the logging functionality on DD-WRT where not sufficient to log DHCP leases/releases, but maybe with the suggestion rajendraone gave you you might be able to find a workaround.

Best regards,

LucF

Thank you again.

Try Linux LiveCD Router
