Hi all,

How do I enable SNMP on my Netgear DG834 Wireless Router? I wanna use PRTG Traffic Grapher to monitor the (actual) bandwidth cause Telkom's wonderfull stats isn't so wonderfull.

Anyone got some ideas? Or can anyone help me setting it up for prtg?

thanks
Rudi
 
Hi Gambit,

Thanks, I got the snmp menu, and I enabled it, but I'm having trouble still. PRTG can't connect to my router via SNMP.... I got it yesterday, but as soon as I installed PRTG on my server, it just doesn't connect.

Is there something else I need to do too?
 
Great

Know any other hidden menus on this unit? Judging by the above reply, there may be a reason this menu is hidden ;-)
 
Well.. I got it... I miss spelled the community string... what an idiot...

thanks

The only other nifty hidden menu that I know about that is usefull if you want to establish the ppoe connection(s) from your computer(s) instead of on the router is the router/modem mode selection menu http://192.168.0.1/setup.cgi?next_file=mode.htm
 
What happened next?

Hello Tjoppie & all. Thanks for the useful tips sofar. I'd like to get the same results as well.
Unfortunately I can't get PRTG to get data out of the netgear.
Filled in all fields.

- I managed to activate snmp on my netgear dg834g (v2.10.22)
- my adsl settings are: LLC-Based, vpi = 0, vci = 34
- as far as I know it is set up bridged mode

Also I do not seem to get into the modem via telnet.

Do you have any suggestions? Something I forgot?
 
One of the problems I had when I configured this was firewall settings aswell... check your firewall settings too.. I don't know why, but they gave me trouble.

I don't think the SNMP works too great on this router, as PRTG oftenly reports incorrect data, and more often than not, PRTG can't connect to it...
 
thanks for the speedy reply :)
Bringing down my firewall did not result into anything though.
Unless proven different I guess we'll have to live wit this. Maybe a future firmware will resolve this?

The default firewall rules in the DG834 block SNMP traffic.

Telnet into the DG834 to adjust the iptables.

# iptables-L
Chain input (policy ACCEPT):
Chain forward (policy ACCEPT):
target prot opt source destination ports
ACCEPT udp -- anywhere anywhere udp dpt:161
DROP udp -- anywhere anywhere udp dpt:161
# iptables -D INPUT 1

— The second line (iptables -D INPUT 1) deletes the default Netgear iptables rule that drops SNMP packets. The change to the rules is temporary and you will need to go through the process again to re-enable SNMP if the router is rebooted.

Credit for all the above goes to Grandou, I just copied and pasted.

After you get fix the firewall rules, you should be able to connect with this freeware traffic monitor. It works on my DG834.

Hi guys, I'm reading this post and this is exactly the problems I am having, wonder if you guys have come right and if you can please assist me in setting PRTG to work with my DG834G Router too

I have installed PRTG, turned off my firewall for now to eliminate it as a possibility but still no joy. When I scan for SNMP enabled devices PRTG does detect my various devices how when it comes to monitoring these devices it tells me that it cannot connect

I have enabled SNMP on my router (thnx for showing us how on this topic) and set my Community Name to public but still no joy

I want to give those Telnet settings a go but am not sure how to use the Telnet interface. I know as much as going to run and typing telnet and my routers ip address and logging in but no more. How do I make these changes mentioned in previous post

Have you found easier ways off setting up PRTG or other software for monitoring bandwidth per router connection since your last posts

Please help
thnx

Hi Mark,

I have given up... or waiting for a new firmware to be released. let me know if you get it working
 
Hi

How do i make the change to DG834G via Telnet that you mentioned in one of your previous posts

My telnet knowledge is limited, they exact commands would be appreciated

Thnx
Mark
 
Different IP Monitoring

Hi Guys
Thanks for all the help with this router :)
Just a quick question:
Would SNMP on this router be able to monitor traffic used by different IP's on the network (both wireless and LAN) ?
We just got this router and a new ADSL contract, and need to monitor everyones usage and if it isn't able to do this do you think there's anyway I could setup a small server as a gateway or something to monitor the traffic?
Sorry if this is a stupid question but I'm not a really a network kinda guy.

Thanks in advance for any advice.

I have the same issue, on a DG834G. Can anyone verify that this solution works?

Thanks
 
i tried it long ago and did work for me

problem is when u log into the router with telnet , you mst not switch or reboot the router

i used the app as mentioned oon website and worked fine , but the program has to be open al the time and doesnt log to well
 
can anyone suggest a way or perhaps a router that has bandwidth monitoring capabilities?
 
I have a DG834GUK v3 that I user a program called RouterStats with, which works via SNMP.

To get it to work I had to first use the hidden SNMP enable/disable page and enable SNMP:

http://192.168.0.1/snmp.htm

Then, I had to go into the Firwall Rules section http://192.168.0.1/setup.cgi?next_file=start.htm

Then create 2 outbound service rules.
No. 1 was for SNMP-TRAPS
No.2 was for SNMP

Then I had to create 2 Inbound rules.
No.1 was for SNMP on the modem (192.168.0.1 or whatever you have the modem set at).
No.2 was for the SNMP-TRAPS which I set as 192.168.0.2

Then I downloaded and installed RouterStats from:

http://homepages.nildram.co.uk/~vwlowen/internet/files.htm

For the my modem I had to use it on Telnet mode, which seems more accurate. The graphing is excellent. Once you create those rules PRTG will also work by the way, as will a host of other monitoring software.

Hope this helps you folks out.
