[outages] VPN issues over Spectrum L3 boundaries

[Biddle, Josh]

See if you can get proof with traceroutes and post on the thread that I made to see if we can get some type of answer out of someone. My best guess at this time is that it is some business squabble at the transit provider where these two Internet providers interconnect.

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.

Found a thread in the Spectrum forums talking about the issue finally – it was marked as resolved so I started a new one.

We have several offices over the Ohio and Pennsylvania area that are experiencing issues passing traffic over VPN tunnels (specifically, there is always a Spectrum >< Level 3 interconnect). 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.

Anyone else experiencing any similar issues like this?

Best Regards,
Josh
