Hi Osmocom team We have a basic question about libgtpnl (Linux Kernel GTP-U).
I would suggest that you start with setting this up using OsmoGGSN.
It has built-in support for kernel GTP (via libgtpnl), see the related user manual.
Once that works, you have a "known working" setup and you can start comparing the differences between how OsmoGGSN uses libgtpnl and how you are using it manually.
I have to admit that I never considered using the manual gtp-link/gtp-tunnel commands in a "real" network. Those were only ever used in artificial functional testing.
