High latency and packet loss HELP!! [not solved]

Derelict

Codel won't do any good if the buffering is in the ISP network, which it must be because pfSense won't buffer bloat like that without significant effort.

There is no way to shape on pfSense LAN because he is trying to load balance 3 20Mbit connections into 60Mbit and there is no way for the shaper to know which WAN is saturated when sending out LAN.

He needs to limit downloads on each WAN interface to something that will reduce the buffer bloat in his crappy crappy ISP network.

The only way I can think of to do that on each WAN independently is a limiter on each WAN. That requires 2.4.

It is unknown if 2.4 will introduce something that doesn't work for you. Probably not. 2.4.0-RELEASE should be real soon now.

If you have a 2.3.4_1 installer ready and a current backup you can get back to where you are in about 10 minutes.

@tripplex:

can i just update to 2.4 from 2.3.4_p1? Will it cause any issues?

getting this while updating to 2.4.0:
pkg: cached package pear-Net_Growl-2.7.0: size mismatch, cannot continue
Failed

What, exactly, did you do there to initiate that upgrade?

johnpoz

Yeah I fail to understand such a odd ball setup? If you want 60mbps - why not just get a pipe that big? So you have 3 cable providers in your area but nothing fatter than 20mbps?

I just ordered 500/50 to be installed on wed! ;) Big jump from my 75/10 connection and cheaper too. Sad part is my pfsense VM can not route that that speed, so until I update my vm host or pull trigger on sg3100.. Which wife would kill me on cost of either option right at the moment… So I had to order a unifi usg :( cheapest option that I could find that could handle the speed.. But looks like openvpn and ipv6 tunnels going to be a PITA vs the easy clickity clickity of pfsense.. And didn't tell her about that cost, just that needed new modem to handle the new speed.. So prob in for some shit when she sees the amazon bill ;) hehehehe

tripplex

ok i got it updated 2.4.0 now i am going to set the limiters on the wan.

Is the attached settings correct? because it isn't working to limit the wan speed.

no dude no.. Did you not read the thread I pointed too.

tripplex

there are so much things there i can't find what i needed gonna read through it all.

Derelict

Remove the shaper. You need to use limiters.

tripplex

after creating the limiter where shall i put it on the wan tab of the firewall rule and how is it suppose to be configured i.e. the firewall rule with limiter?

Derelict

On a floating match rule on WAN out.

I used 18/5 just to demonstrate this:

[2.4.0-RC][root@pfSense-b]/root: speedtest-cli

tripplex

Its working but no more latency issue when i drop the bandwidth to 10 mbps but i still get packet loss and eventually the interface goes offline.

Am i right to feel this is a hardware problem?

tripplex

Its happening badly when the speed test tries to upload. the latency is in the thousands.

I have another pc can install pfsense to a hp z200 workstation. Should i do that?

Derelict

It's not pfSense. It's your ISP.

Edit the gateways and tell them to always be up while you test. That way the dpinger alarms won't take interfaces down and the interfaces will stay up.

also are you trying to test through the load balancer? Some tests can create multiple sessions to try and fill the pipe vs using 1 session.. I think your going to have a problem with 3 different wans and shaping if your trying to load balance.

And I am curious if there is any shared connectivity here? So these are 3 different isp with 3 different lines or are you just running 3 different modems from the same cable company?

Upload bufferbloat is easy to fix. Set FariQ traffic shaping on all 3 WAN interfaces, set your bandwidth, and preferably set your default queue to have Codel enabled.

3 different lines with modems from the same ISP.

I just increased the latency threshold on the wan interfaces. working good so far , that's what i did in the past before reinstalling pfsense.

johnpoz

"3 different lines with modems from the same ISP."

For what possible reason?? Makes zero sense - from same isp, so if they have issues all 3 of your connections going to have problems. Your telling me the fastest connection they can give you is 20.. On cable? So you got 3 of them?

tripplex

There 50mbps is the next step from 20 mbps but the price for that bandwidth is so high i couldn't afford it but three 20mbps line is almost the same cost, so i went with that option. Seems now i am paying the price for that. :-[ :-\

Thanks to everyone who help on this thread. And I installed pfsense on the hp z200 workstation and it had the same problem as the IBM so its definitely the ISP as [b]Derelict said.

johnpoz

With cost of 3 modems.. That you are renting or you bought.. Sorry but I don't so how this was ever a viable option for anything.. And could not make sense cost wise.. What going to save 5 bucks or something for the 3 lines vs the 50mbps line?

Live with the 20.. If that is not enough then get the 50.. You can not just magically put a bunch of lines together and think its going to act like 1 fat pipe.. It just doesn't work that way no matter how many people want it too..

Yes load sharing is some cool shit.. Works when you have multiple users.. How many different users do you have trying to use this connection setup?

chpalmer

Two of our people using the tg862 both had different issues. Have you tried any other modems?
