Has ping / tracert been blocked on 5g network?
Before yesterday (10/17/2022), I’ve always had a command prompt window (MS Windows) up running a constant ping at 3 second interval - so I can tell when the network starts to degrade or just stops re...
Having same problem as others, in OC NY. Using TMHI as secondary WAN, with opnsense cluster behind it. Use ICMP to detect gateway outage.
Got a sagemcom modem a week & a half ago, integrated it into my network. Worked fine for a day or two, then suddenly couldn't ping through it. Didn't take metrics; figured something went sideways & that 611 would make it right. Tech support swore up & down that they didn't block ICMP, that it must be "a problem with my computer, and that I should contact my computer manufacturer about ICMP issues." (That would be pcengines & freebsd; they're not the problem.)
Sent me a new modem (another sagemcom), again worked fine for a few days, then back to nope. Have switched the gateway monitor IP to that of the modem - not optimal, since it can only tell if the device is responding, not whether it's routing packets to the outside.
Since both modems [briefly] worked as expected, it makes me think it's a firmware update that's causing the problem; whether it's a bug or a new policy, I can't say. Either that, or they took exception to my pings, though I would argue that 1pps isn't excessive.
