Is anyone from Verizon on this list? They probably are but not allowed to comment. I would love to know if there is an official comment on why they do this. It annoyed me when they first implemented and I was trying to diagnose an issue with a client. Regarding your edge device: Same here, I had ubiquity gear at my GW for a while and before that PFsense.

In North NJ, 3 different accounts I can verify have ICMP blocked as of sometime earlier this year or late last year so have to use udp to get a real traceroute. Could not be deployed in all areas the same way.I noticed this about the same time I installed Ubiquiti gear at home, December 2018. Until this thread, I thought there was something wrong with my gateway router config. I could do UDP/TCP traceroutes, but ICMP kept dying. Glad to know it isn't my gateway, but frustrated as hell that Verizon decided that a few customers doing less-than-ideal things was enough to cut a standard network protocol off at the knees. --------------------------------------------------------------------------- Peter Beckman Internet Guy beckman () angryox com http://www.angryox.com/ ---------------------------------------------------------------------------
