Open5GS Network Setup
Setting up a 2-VM 5G network

The following guide explains how to set up a virtual 5G network consisting of the Open5Gs Core and an UERANSIM access network. We use two virtual machines running Ubuntu that connect to each other through a NAT. After finishing the guide, you should be able to connect a UE to the Internet through the core network, interfere with the UE and gNB through a command line interface, and sniff the core network traffic of the individual network functions.
