Apparently this was cleared up over night. I don't see why they would have done double natting for one day... :-) We're checking with our clients. But the other itsp says they're good now. Really weird. Thx. Shri Sent from my mobile device. On Apr 20, 2012, at 9:16 AM, "Matthew S. Crocker" <matthew at corp.crocker.com> wrote:

Is Verizon doing NAT44 or NAT444 on their network to save IP space? Maybe the end use is getting double NATted?

hey all,

another ITSP happened to mention to me that Verizon FIOS services were having one-way audio issues yesterday. Since most of our customers connect privately back to our network. i didn't think much of it, however, we do have a couple of clients coming to us publicly via fios. they are experiencing the same the issue right now. Has anyone heard or experienced anything with regard to this issue?

thanks, shri

Verizon Stripping and dumping packets

Verizon is discarding traffic coming INTO their network with a high priority QoS tag. Ryan proved this by stripping the QoS tag out of an Edgewater on our IP to a VZ IP. Traffic never made it to the far router.

The other piece is they are changing the packets: Packet leaves like this 17:13:01.741406 static-96-254-116-37.tampfl.fios.verizon.net.500 > 192.216.157.26.500: udp 80 (DF) [tos 0xb8] and arrives like this 17:13:01.812518 static-96-254-116-37.tampfl.fios.verizon.net.500 > 192.216.157.26.500: udp 80 (DF) [*tos 0x18*]

They have broken VPNs and SIP traffic for a large amount of FiOS customers.
