Gateway WAN keeps on having packet lost
-
What hardware are you running pfSense on?

T620 (i think)
AMD GX-420CA SOC with Radeon(tm) HD Graphics
16Gb ramIntel 4x NIC card don't remember the exact model
-
Hmm, and you're running 2.5.2?
And this just started happening? It was running without loss previously?

Yes on 2.5.2. I can't say how long has this been going on. In fact for many months I don't log onto PFsense. I recently tried to add a MyQ garage opener and realised that it won't report online (I have another thread here on this subject). which triggered me to look at PFSense.
Now that I'm thinking of it, my kids play Roblox and they are constantly kicked out of their games. It's been quite some time now.
-
Ok can we assume that without any other traffic using the connection the WAN gateways show as up and without packet loss?
If you connect via ssh and run
top -aSHand the command line do you see any CPU cores being run at 100%? (idle processes at or close to 0%).That CPU appears to be well capable of 1Gbps but it's single thread performance is not fantastic and em NICs run with 1 queue. I still wouldn't expect anything like this though.

The WAN interface never really get reported as being down which is very weird, but on the gateway status, it does show off. It also seems that IPv4 shows to be off more often than IPV6.With nothing else in the mix, I still experience packet loss.
top -aSH didn't pull up any CPU info.
Diagnostics/System activity it does show that the WCPU cores are all running at or close too 100%

If anything was using a lot of CPU it would show above that.

Hmm, that was whilst you are passing traffic? Like running a speedtest?
I expect to see far more CPU usage than that. Nothing there looks like an issue though.
-
sorry that was it idling here's one while I'm running a speed test. Noticed how I drop to around 500Mbps now
-
Mmm, nothing unusual there either. No CPU core maxed out.
I guess I would be running a packet capture on the WAN at this point to see what's actually happening. Are there a load of retransmissions or packet fragments etc.

@stephenw10
i'll try to do that...how long should I be running the packet capture for?here's a screen capture of the entire speedtest process.

-
I would start with 1000 packets showing the beginning of the test. If there's something broken there it should show pretty quickly.

@stephenw10 Here's what it captured. Not sure how to decode this information.
-
You need to look at the actual pcap file in Wireshark to see anything useful really.
-
@stephenw10 attached is the cap file. I can see that there are icmp errors and some extremely long response time in the traffic but is not smart enough to analyze it to identify the exact issue. :(

Hmm, well the WAN was quite busy at that time. The 1000 packets covered only 2.3s.
Load of random port UDP traffic in there. Clients behind torrenting maybe?The WAN sent 5 pings in that time to what I assume is the gateway IP and no replies came back. Did you set the monitoring back to the gateway IP?
Did you enable promiscuous mode when doing that? That's usually a good idea as some things can be hidden otherwise.
Overall apart from the lack of ping responses it doesn't look too terrible.
Are you able to retry that with the WAN in promisc mode and preferably without the LAN side client spewing UDP traffic?

I'll have to try again in the morning when wife and kids don't need the internet. When they're up every one is online
-
@stephenw10, look at the capture and I am seeing windows update In Execution, in my case this has come to cause a problem
-
@silence But half of this morning no one was online and even when my computer was the only thing connected.
And then it still doesn't explain that I don't get ping timed out when I bypass the offense box
