L2TP and L2TP/IPsec support for NetworkManager

NetworkMananger-l2tp

NetworkManager-l2tp is a VPN plugin for NetworkManager 1.2 which provides support for L2TP and L2TP/IPsec (i.e. L2TP over IPsec) connections.

For L2TP support, it uses xl2tpd ( https://www.xelerance.com/software/xl2tpd/ )

For IPsec support, it uses either of the following :

• Libreswan ( https://libreswan.org )
• strongSwan ( https://www.strongswan.org )

Building

./autogen.sh
./configure  # (optional, see below)
make

The default ./configure settings aren't reasonable and should be explicitly overridden with ./configure arguments. In the configure examples below, you may need to change the --with-pppd-plugin-dir value to an appropriate directory that exists.

Debian and Ubuntu (AMD64, i.e. x86-64)

./configure \
  --disable-static --prefix=/usr \
  --sysconfdir=/etc --libdir=/usr/lib/x86_64-linux-gnu \
  --libexecdir=/usr/lib/NetworkManager \
  --localstatedir=/var \
  --with-pppd-plugin-dir=/usr/lib/pppd/2.4.7

Fedora and Red Hat Enterprise Linux (x86-64)

./configure \
  --disable-static --prefix=/usr \
  --sysconfdir=/etc --libdir=/usr/lib64 \
  --localstatedir=/var \
  --with-pppd-plugin-dir=/usr/lib64/pppd/2.4.7

Debugging mode

Issue the following on the command line :

Debian and Ubuntu

sudo killall -TERM nm-l2tp-service
sudo /usr/lib/NetworkManager/nm-l2tp-service --debug

Fedora and Red Hat Enterprise Linux

sudo killall -TERM nm-l2tp-service
sudo /usr/libexec/nm-l2tp-service --debug
