Help needed, BQM is solid red

Hello,

I tried to setup the BQM but the graph is solid red and i'm out of ideas on what to do, i need it to work so i can get an idea of my current ISP as i'm migrating soon so i want to compare.

Setup:

Netgear DG843Nv1 in Modem only mode using (DGTeam firmware) connected to an Asus RT-N66U using (asuswrt-merlin firmware)

My IP is static with my current ISP and i have enabled the setting 'Respond Ping Request from WAN' on the RT-N66U but BQM still won't work.

I have tried the traceroute and i think it's okay.

any ideas/suggestion please?

http://whatismyipaddress.com/traceroute-tool does the last hop get a time to your IP address ?

http://whatismyipaddress.com/ to check IP

No the last hop doesn't get a time to my IP it just say's N/A, i guess that's bad?

its very likely the router is blocking it even though you have told it to respond to pings, turn off, custom firmware can be funny sometimes (turn off UPNP and make sure there is no port forwarding active)

if the router is in modem mode so the second router is getting an internet IP ? (should not be 192 on the WAN page on the second router, if it is then all you have done on the first router is disabled NAT or just turned of the wifi)

I have tried turning off UPNP and turning off port forwarding but it was still solid red.

The IP on on the second router (RT-N66U) is the same IP that is shown here.. http://whatismyipaddress.com It's not a 192 IP.

Maybe pings are being blocked by the Netgear DG843Nv1

I thought that but is that even possible if the the DG834N is bridged properly?

Isn't the pings sent between the RT-N66U and the BQM? and the DG834N in modem only mode doesn't come into it, unless it wasn't bridged properly which I'm sure isn't the case.

your evidence suggests that either a) the netgear is not completely transparent or b) the RT-N66U is not responding to WAN pings.

In these situations the firewall logs (if available) may show what's happening.

You could lash up a test to try the RT-N66U response to WAN side pings perhaps ?

I just done a couple of tests to 'try' and eliminate the DG834N being set up wrong i.e not being completely transparent.

I setup two other modem/routers in Modem only mode/bridged to the RT-N66U and BQM still didn't work.

So i think it's safe to say it's got to be the RT-N66U blocking the WAN pings some how? because it's a bit unlikely if impossible that i have setup all 3 modem/routers wrong.

The person that built the custom firmware (merlin) emailed me and said that BQM works for him on he's RT-N66U, so what gives?

Yes i think there is a way to view/track the firewall/logs.

How would i run the test?

On the factory ASUS firmware you need to set the option under "Firewall" on the big left menu, called "Respond Ping Request from WAN" to Yes. I've not tried Merlin's firmware yet on my N66U.

If that is set on the ASUS responds, as it works on my BQM (using FTTC).

I have turned this on, its currently set to yes. It was the first thing i did.

still sounds like its been blocked at the router end

do you have another router just to Rule it out, or an PS3 that you can can Set the DMZ to temporarily as it Will respond to pings on the PS3 (been googing the router firmware see if there has been issues with ping not working not found any but found one that was using an static IP on the PS3 wired with DMZ)

you Could also plug the cable into your PC from the Bridged router and enabled Ping/ICMP on your computer firewall (make sure you press Public when windows pops up with the Set Network Location if it does) and see if it responds to pings (not sure if setting the ping/ICMP is needed, i assume windows blocks pings be default if its not on an local lan IP range)

Thanks for taking the time to Google the firmware to try and help me, much appreciated.

Nope in don't have another router, but I'm confident its the router because I have tried 2 other modem routers in modem only mode and it still didn't work plus when I used the DG834N on its own a while back BQM worked fine after I enabled WAN ping.

However I do in fact have a PS3 which is already in a DMZ w/ a static IP and wired. Is this what I need? As you said it will respond to pings.

yes it should be responding to pings now, not your router, is there any firewall settings on the router you can turn off (typically DMZ should bypass all of that)

is it based off DDWRT

you still need to rule out that the Router or the modem is not blocking pings (depends how it is set up)

Plug the PC or laptop or PS3 Directly into the router that is in bridged mode (not the N66U) your device should get internet right away (i am assuming its just normal Bridge where it is just handing the internet IP over to the Asus router)

yes the PS3 should respond to pings in an DMZ zone (the respond to ping option on the router should be meaningless once DMZ is used, does not matter if respond to ping is on or off, if the PS3 is off no pings will respond if it is on it should respond as i have seen in forums)

I got an email from the guy that built the merlin firmware and he told me to turn on the logging of dropped packets in the firewall settings, so i turned it on to log both dropped and accepted packets.

I then ran a traceroute to see what would show in the log and there were entries.

I had a look and i noticed that the destination IP was for my PS3 which is odd as i thought the IP should be for my PC. So i ran a second traceroute to double check and again the IP was for my PS3. also odd was all entires were accepted none dropped.

At this point i decided to turn my PS3 on as the destination IP was pointing to it and guess what? when i ran the traceroute i got a time on the last hop. Result!... Now i'm thinking progress...

Straight away, i created a new BQM and not surprisingly it's now working

So now the burning question....

Q: Why did i need to power on my PS3 for the BQM to start working?

The only thing i can think of is that my PS3 is in a DMZ, but i still don't see how that would make a difference

the DMZ overrides all rules on the router, the PS3 is off so it cant respond to the ping requests (DMZ does not care if the PS3 is on or not it still send the packets to it)

like in the other post, if DMZ is used respond to ping option on the router does not matter if its on or not its ignored as all packets are been sent to the IP that you have used, in your case the PS3 that was off so the packets was going nowhere (basically a black hole)

if you just turn off DMZ now you find the pings will end now at the router (its really better if you do not use DMZ unless you really need to) and as long as respond to ping is enabled it will take over

Got this all worked out in the end, DMZ was the culprit because of the way WAN pings are handled when it's active on an IP.

Thanks to everyone who offered assistance in trying to solve this, I appreciate it.

Two quick questions...

Is it okay to run both BQM and f8lure at the same time? or is it best to run 1 at time?

also which is the preferred monitor in your personal opinions? BQM? or f8lure?

Running both is fine just gives you more room for comparison.
