Setting up TUN device (No persistent after rebooting)
Install TUN/TAP driver
- You can download it from http://tuntaposx.sourceforge.net/
Configure the TUN device.
$ sudo ifconfig lo0 alias 127.0.0.2 netmask 255.255.255.255
$ sudo ifconfig lo0 alias 127.0.0.3 netmask 255.255.255.255
$ sudo ifconfig lo0 alias 127.0.0.4 netmask 255.255.255.255
$ sudo ifconfig lo0 alias 127.0.0.5 netmask 255.255.255.255
Enable IP forwarding & Masquerading
$ sudo sysctl -w net.inet.ip.forwarding=1
$ sudo sh -c "echo 'nat on {en0} from 10.45.0.0/16 to any -> {en0}' > /etc/pf.anchors/org.open5gs"
$ sudo pfctl -e -f /etc/pf.anchors/org.open5gs
Tip: The script provided in [$GIT_REPO/misc/netconf.sh](https://github.com/{{ site.github_username }}/open5gs/blob/master/misc/netconf.sh) makes it easy to configure the TUN device as follows:
$ sudo ./misc/netconf.sh

Building Open5GS
Install the depedencies for building the source code.
$ brew install mongo-c-driver gnutls libgcrypt libidn libyaml libmicrohttpd curl pkg-config
Install Meson using Homebrew.
$ brew install meson
Git clone.
$ git clone https://github.com/{{ site.github_username }}/open5gs
To compile with meson:
$ cd open5gs
$ meson build --prefix=`pwd`/install -D c_std=c99
$ ninja -C build
Check whether the compilation is correct.
Note: This should require sudo
due to access /dev/tun0
.
{: .notice--danger}
$ sudo ninja -C build test
Tip: You can also check the result of sudo ninja -C build test
with a tool that captures packets. If you are running wireshark
, select the loopback
interface and set FILTER to s1ap || gtpv2 || diameter || gtp
. You can see the virtually created packets. testsimple.pcapng({{ site.url }}{{ site.baseurl }}/assets/pcapng/testsimple.pcapng)

You need to perform the installation process.
$ cd build
$ ninja install
