Hi and thanks for reading.
We have always-on VPN sat up in our Network.
Some users complain that they can only connect to local recourses for a very short time. After that it shows as connected on Win 10 pc, but no traffic can go over until they disconnect and connect again.
If we test by running a continuous ping it stays up. Until we stop ping. and then VPN tunnel close after 5 sec... (but still shows as connected)
During testing, we also found that connecting over hotspot (via iPhone) it works fine.
Also some users repport they have no problems. So ISP is a factor. But strange that as they can connect and that as long as a ping is running the tunnel is up!!
