Hugh packet loss via pfsense

chpalmer

We need a whole lot more information to be able to even try and guess. But guessing- you could have a bad interface, bad cable, bad hair day, ect.

Are you seeing any errors on your interface from the dashboard widget?

Thanks for your support :),

I too have changed the NIC's and new cables, :(

Ref the screen shot.

Download the pcap and attach after it stops (Should only run for about a minute.)

What do you get if you ssh into pfSense and:

ping -i .25 -c 100 122.165.128.1

FWIW I get about 30% packet loss there too:

–- 122.165.128.1 ping statistics ---
100 packets transmitted, 70 packets received, 30.0% packet loss
round-trip min/avg/max/stddev = 224.001/234.627/272.539/8.829 ms

Looks like you're in a pretty dark corner of the internet.

Thanks for ur support, i'll check and update

Same results here. I'm currently seeing 34-42% packet loss from your default gateway (122.165.128.1).

Use PingPlotter to gather evidence on exactly where the packet loss is and take it to your ISP (Assuming the issue is downstream).

You also are using DSL in India, which may or may not be an issue in and of itself, but I would switch broadband technologies if possible.

if i directly connect my ADSL router to Switch, there is no packet loss.

Something tells me this is unreliable. Frustrating.

Thank U all for giving support :), i'll use the pinplotter.

If i connect any node directly to ISP' router and trigger continuous PING, there is no loss in packets.
That's what i tried to convey earlier.

Earlier, I raised issue to ISP provider, they came and checked the physical line, then hard reset the ASDL router and tried to ping, result= success without firewall (pfSense). couple of minutes later after connecting pfSense tried to ping, result=loss (partial). :o

Now, i'll use this PinPlotter in both cases with/without pfSense and get back.

Your internet sucks, friend. It's not pfSense.

2 hops away from your gateway-

Ping statistics for 182.79.220.190:
    Packets: Sent = 100, Received = 99, Lost = 1 (1% loss),
Approximate round trip times in milli-seconds:
    Minimum = 243ms, Maximum = 260ms, Average = 245ms

your gateway-

Ping statistics for 122.165.128.1:
    Packets: Sent = 100, Received = 61, Lost = 39 (39% loss),
Approximate round trip times in milli-seconds:
    Minimum = 244ms, Maximum = 375ms, Average = 249ms

Your gateway router is hammered! Last time I saw pings like that the site had been struck by lightning.

My guess is when the ASDL router is in use, it's using a different route (or gateway) to the internet, which is why everything appears fine when using their router. Gather your evidence via PingPlotter and go from there.

Something connected to the router, do you have a switch in between the router and the client? Client doing DHCP so it's getting address/gateway/DNS from the router or beyond? If so, and the pfSense box is also doing DHCP you should be able to compare those values. Don't forget to check link state; make sure everything matches on Speed, Duplex and MTU.

Note: ADSL Router in Bridge Mode.
I've tried Netgear DGN2200 ADSL2+ router too.

Sometimes peoples are meaning that there ISP router is in the so called "bridge mode" and it is
working likes an ordinary and pure modem and then also really often some other peoples are meaning
they was bridging the WAN port of their pfSense box to that ISP router and also really then the goal or
"benefit" is;

packet loss
packet drops
port flapping
unstable connection

But all in all if the pfSense box is doing actively DHCP and the ISP router in front of this pfSense is also
doing DHCP it could produce also this behaviors or creating this issues. And this is not rarely seen.

My question: who is "Hugh", and why is he worried about packet loss via pfSense?
