[outages] VPN issues over Spectrum L3 boundaries

[Justin Oeder]

We had a similar issue last week that we chalked up to a Spectrum outage.  

Because this was all new install we have not gone back and tested again yet but very similar to you - Multiple sites over Ohio.  VPN would establish and one side would send traffic and it would be received on the other end.  The other side would send traffic and it would not be received.

It is a very strange issue. The VPN tunnel will actually establish, and if you source your ping from inside the internal network across the VPN tunnel to the destination, the traffic gets there and replies, but the replies never make it back to the original sending point.
