Hi all,

we are experiencing a strange issue with our afs servers.=20
When people are working outside the office, they can access our =
fileservers over our VPN when the do this using WiFi, when they contact =
over our VPN using a 3/4g mobile data connection it fails.=20
We are completely puzzled since the connection is made suing the same =
VPN, so except form the physical layer, everything seems the same.
The afs servers can be ping=E2=80=99ed, all other services work =
fluently. Only the caching daemon seems  not being able to contact the =
file servers.=20
Clients are macOs machines using the auristor client.

Anybody an idea on the root cause ?=20
Any proposal how to further debug this issue ?

Any help is heavily appreciated,

Tim=20
