Enable IP forwarding & Masquerading
$ sudo sysctl -w net.inet.ip.forwarding=1
$ sudo sysctl -w net.inet6.ip6.forwarding=1
$ sudo sh -c "echo 'nat on {en0} from 10.45.0.0/16 to any -> {en0}' > /etc/pf.anchors/org.open5gs"
$ sudo sh -c "echo 'nat on {en0} from 2001:db8:cafe::1/48 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/main/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 nghttp2 pkg-config libusrsctp libtins talloc
Install Bison and Create soft link.
$ brew install bison
$ export PATH="/usr/local/opt/bison/bin:$PATH"
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
$ ninja -C build
Check whether the compilation is correct.
Note: This should require sudo due to access /dev/tun0
.
{: .notice--danger}
$ sudo ./build/tests/attach/attach ## EPC Only
$ sudo ./build/tests/registration/registration ## 5G Core Only
Run all test programs as below.
Note: This should require sudo due to access /dev/tun0
.
{: .notice--danger}
$ cd build
$ sudo meson test -v
Tip: You can also check the result of 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 || pfcp || diameter || gtp || ngap || http2.data.data || http2.headers
. You can see the virtually created packets. [testattach.pcapng]({{ site.url }}{{ site.baseurl }}/assets/pcapng/testattach.pcapng)/[testregistration.pcapng]({{ site.url }}{{ site.baseurl }}/assets/pcapng/testregistration.pcapng)
{: .notice--info}
You need to perform the installation process.
$ cd build
$ ninja install
$ cd ../
Building WebUI of Open5GS
Node.js is required to build WebUI of Open5GS
$ brew install node
