Using L2TP in Ubuntu 12.04 Precise Penguin
For our new company I want to provide VPN access through L2TP in addition to PPTP.
After I had installed network-manager-strongswan the configuration dialogue of network-manager crashed. Being not the only one having this problem I installed the 1.3.0 build of network-manager-strongswan and now I can configure my L2TP connection as expected:
wget http://launchpadlibrarian.net/108979339/network-manager-strongswan_1.3.0-0ubuntu1_amd64.deb sudo dpkg -i network-manager-strongswan_1.3.0-0ubuntu1_amd64.deb
