You might be able to infer that from the hops that show up in traceroutes.
I went so far as to even randomize source/dest ports on each end in case it was some sort of misguided filtering (ie: port 12345 -> 54321 instead of 12345 -> 12345).
That really makes it odd. If you tried changing the src/dst ports with v4, and your VPN traffic still would not pass, but iperf would, what kind of filtering/breakage could CL or Comcast have that would just stop your VPN traffic regardless of ports? I wonder if this is a misguided/misbhaving filter rule, or something actually broken eating your packets. Having dealt with something far stranger many years ago, I totally get the aspects of "big telco can't help / won't let you even talk to someone who can understand your explanation of the issue" and "I don't care how I solve this, as long as I can make the issue go away." ---------------------------------------------------------------------- Jon Lewis, MCP :) | I route StackPath, Sr. Neteng | therefore you are _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
