Verify support with the software manufacturer before creating the rule on the Zyxel router. This will depend on your VPN clients compatibility, not all clients support IKEv2. IKE Version – Options are IKEv1 and IKEv2, select the appropriate IKE version you wish to use.VPN Gateway Name – Please provide a name for the rule.On the top left of the window click the " Show Advanced Settings" button to view all the option available in this menu. Click the " Add" button to create a new rule. In the IPSec VPN menu click the " VPN Gateway" tab to insert a Phase 1 VPN policy configuration. Once in the web configuration page go to menu, Configuration → VPN → IPSec VPN to begin the VPN policy/rule setup. To begin the configuration of the VPN policy on the ZyWALL/USG router, please open a web browser and access the Zyxel routers WebGUI. This walkthrough will help configure the VPN setup on the IPSecuritas VPN client (version 4.6.1). Third party IPSec software is required to establish the VPN connection as current operating systems lack a built-in IPSec client. This guide will reference the IPSec protocol to establish a secure VPN tunnel between external hosts (users connected to the internet outside the company network structure) and the ZyWALL router. There multiple types of VPN protocols/technologies, that can be used to establish a secure link to company network, L2TP, PPTP, SSL, OpenVPN, etc. A remote access VPN (client-to-site) allows employees who are traveling or teleworkers, secure access to company network resources. VPNs are used to transport traffic over the internet of any insecure network that uses TCP/IP communications. OverviewĪ VPN (virtual private network) provides a secure communication between sites without the expense of leased lines. The other options should be fairly obvious.This guide will assist in the configuration of the IPSecuritas VPN Client (version 4.6.1) for VPN connectivity with Zyxel's Next-Gen ZyWALL USG routers. Gateway ID : Phase 1 Algorithms : 3des-sha1-modp1024!.In the nework-manager-l2tp IPsec Options dialog box, enable IPsec and use the following options: You will need to logout of your desktop environment (or reboot) for gnome-shell to properly pickup the installed plugin. sysconfdir=/etc -libdir=/usr/lib/x86_64-linux-gnu \ Prerequisites packages (note : you can safely copy and paste the \ shell line continuation character) : sudo apt install \ Unfortunately the version of network-manager-l2tp in the Ubuntu repository won't support the Gateway ID, so will need to build from source. You might find it easier to use the network-manager-l2tp VPN GUI client which uses strongswan and xl2tpd to do L2TP/IPsec connections. So the ike (phase 1) and esp (phase 2) lines should be : ike=3des-sha1-modp1024! I then used netExtender by SonicWall to then make the connection work and now use Remmina as my remote desktop client.Īccording to the following page, Diffie Hellman Group 2 is modp1024 : In the end, it turned out to be most likely a setting in the firewall. Installation worked fine, but I fear I miss something in the configuration.įor nf and crets, see above. Unfortunately, the connection still won't set up. Took me some time, but I finally tried the wonderful answer from Kosovic. Please let me know in case I missed some important information, I will then try to add it. # Following line was added by NetworkManager-l2tpĪnd after setting up things correctly, how can I then connect to my company computer as it would be possible with Remote Desktop on a Windows machine? # SonicWall unique for /etc/crets: : PSK "MY%SHARED%SECRET" I tried this as /etc/nf: # nf - strongSwan IPsec configuration file
