Lorenzo Cavallini lorenzo.cavallini at gmail.comHi, thanks for your answer. You are right, it was a configuration problem related to the SGSN. In particular, the encapsulation local-ip parameter in the ns section. I was using the same value used for gtp localip, but this was creating the issue. Now I set this ip to some random local ip (127.0.0.10) and it works fine. Can you explain what the encapsulation setting is actually doing? The documentation is not very clear on this, I thought this was supposed to be the same value as the gtp localip. Everything else is working fine anyway. By the way, do you recommend to switch to the "split" architecture right now? Or is there a timeline for when OsmoNITB will be deprecated? Thanks!
