Libreswan server #152

Closed pawel-zajac90 closed 3 years ago

pawel-zajac90 commented 3 years ago

Hello once again ;) my client and server os is ubuntu 20.04 i'd like to connect to server based on Libreswann with network-manager-l2tp, but it's using strongswan. Is this correct way?

  1. Install network-manager-l2tp & network-manager-l2tp-gnome
  2. Uninstall Strongswan with all plugins
  3. Install libreswan

I'm using this configuration: https://github.com/hwdsl2/setup-ipsec-vpn

libreswan or strongswan clients should be compatible with a strongswan server, if it doesn't work it is a bug.

the network-manager-l2tp package has a dependency on (strong | libreswan), i.e. either will satisfy the dependency,

If you haven't installed libreswan or network-manager-l2tp* packages, you could issue:

sudo apt install network-manager-l2tp-gnome libreswan

or 

sudo apt install libreswan
sudo apt install network-manager-l2tp-gnome

you could optionally add, network-manager-l2tp, but is redundant as it is a dependency of network-manager-l2tp-gnome.

If you have already installed network-manager-l2tp and strongswan, you can issue the following which will automatically uninstall the main strongswan package while installing libreswan:

sudo apt install libreswan

You could then optionally remove and remaining strongswan packages.

i had network-manager-l2tp installed so i just installed libreswan...and now none vpn works...

dkosovic commented 3 years ago

If none of your VPN connection now work, I would need to see some log output, e.g. journalctl --unit=NetworkManager . See the Debugging section of the README.md file for more debugging details:

If you didn't allow the libreswan package to replace /etc/ipsec.conf with its own copy, you probably have a broken /etc/ipsec.conf for libreswan.

You could purge /etc/ipsec.conf and reinstall with:

sudo apt purge libreswan network-manager-l2tp network-manager-l2tp-gnome
sudo apt install network-manager-l2tp-gnome libreswan
