Hey all! I'm presently trying to move a functional small Magma setup to a new machine, but I'm running into a funky bit of behavior late in the connection establishment process on my new instances. SetupMy setup is as follows, and has worked with previous versions of Magma:

Please share the MME logs with log level as DEBUG. |

As @prabinakpattnaik , it will be good to have the mme.logs. Few observations I can see:
It will be great if it can be tested on latest master and share mme.logs in case of issues. |

Hey all, In spite of enabling a bunch of DEBUG log settings, it looks like mmed still logs in only INFO. Regardless, I got some useful logs, which I've attached. They seem to indicate a timeout to receive the InitialContextSetupResponse, which can be clearly seen in the pcap (albeit fragmented). My setup does pass over an IPSec tunnel, but the MTU should be more than enough to accommodate, and I've decreased the MTU on the eNodeB to 1400. Normal setup

Hey all, Oddly enough, in spite of setting reduced MTUs, etc, this was resolved by removing the IPSec tunnel from the picture and putting the two directly adjacent in layer-3 space. Something to be looked at so the IPSec transport use case can be looked into for the future, but for now I'll close this issue. |

Hi @FrankPetrilli , we are able to establish PDU session over IPsec tunnel. Please find attached snaps and Pcap for reference. |
