Got Static IP, But having intermittent packet loss to Gateway.

[nishantt6969]

@imdarkray yes its resolved, no packet loss anymore. Opt for ip again.

@nishantt6969 I do not wish to change the IP. I have been using this IP for a long time. Is there anything I can or the backend NOC team do?
I am in direct contact with the backend team, but they cannot find any issue.

packet loss can be due to mtu size, try lowering by 10 points each time till there is no loss for 5 or 6 times

@imdarkray you need to get location of your ip changed, ask them to assign you a different gateway. Thats the way I got it working.

@deltaechov my packet loss issue to default gateway isnfixed now by using another ONT(Huawei). Which router are you using?

@nishantt6969 was it really resolved after changing the ONU to Huawei ONT ? I can try this. I can ask them to arrange this ONT even if it's old.

I was moved to another port from backend. Now facing a similar issue.
100% Packet loss for a few seconds in the gap of 30mins to 2 hrs.

ZyXEL ONT on bridge to Pfsense with static IP.
@nishantt6969 @deltaechov were you guys able to resolve this?

You can try adjusting ARP timeout. It worked for me.
This is for pfsense, maybe will work for opnsense as well.

net.link.ether.inet.max_age=900

in system tunable

@deltaechov I have just setup the opnsense to check if the disconnection happens in there or not.
I have added a new value net.link.ether.inet.max_age=900 in the opnsense tunables. Let's see how it goes.

Are you still using Airtel static IP? on opnsense or pfsense? Is this the only change you have done?

 

[nishantt6969]

@imdarkray sorry, I just checked and got to know the issue of packet loss is not solved yet as when I do tracert of any of the sites such as broadbandforum.co, google.in there are packet loss to some ips.

@imdarkray check this out

Yes, I am still using static IP on pfsense (the only reason I am pfsense is telegram notifications). Yes, that is the only change I have made. Since then didn't face gateway packet loss issues.
