Gateway offline, Packetloss
-
@stephenw10 Can you please help me setting up the max age.
-
At the command line run:
sysctl net.link.ether.inet.max_age=10That can really only be as a test though. 10s is a ridiculously short ARP timeout.

@stephenw10 Okay Sir I will try that
-
@stephenw10 Done Sir!
-
Did it make any difference?
-
@stephenw10 I haven’t checked it yet, i m out. Can i let you know by tomorrow. Sorry !
-
@stephenw10 No Still the gateway is showing offline, I will try to do a Pcap and send you the file.
-
@stephenw10 It is working, Thank you Sir for your help. Just this command helped.
sysctl net.link.ether.inet.max_age=10 -
Ok, so that proves it's some odd ARP issue but it appears to be at the provider.
You should contact them and ask why you are having to send them ARP requests every 10s to prevent the gateway forgetting about you.
I still think it's probably another customer trying to use the same IP address. Setting the ARP timeout so low will have completely broken it for the other customer though so they will be complaining to the ISP.
I did ask this before, but just to confirm, there is no possibility that you have another device connected using the same IP?
If it was connected to the same link as pfSense you would see pfSense complaining in the logs because it would be able to see the ARP broadcasts from the other device. So I doubt that's the case.Steve
