Configure the L2TP VPN, including the IP address range it assigns to clients. To configure the FortiGate unit, you must: Configure LT2P users and firewall user group. Configuring the FortiGate unit.To create a FortiClient profile CLI: This example creates a profile for Windows and Mac computers. FortiClient VPN 6.4.4 should be.Enable to configure the FortiClient VPN client, and enter the VPN con- figuration details. Configure security policies.This section describes how to set up a VPN that is compatible with the Microsoft Windows native VPN, which is Layer 2 Tunneling Protocol (L2TP) with IPsec encryption.NOTE: FortiClient VPN 6.2.6 should be installed on Mac systems running macOS 10.12 (Sierra) and 10.13 (High Sierra).
Does anyone have a solid version of Forticlient on their Mac that is currently working with IPsec VPNs I've tried a few different versions and none seem to work, some barely even function.For troubleshooting information, refer to Troubleshooting L2TP and IPsec. The newest version doesn't seem to work as it has a documented bug related to IPSec tunnels. (including Azure) do not allow virtual appliances to modify layer 2/3 MAC/IP tables.Trying to use Forticlient for an IPSec VPN on Mac OS Catalina. Set device-groups mac windows-pc config forticlient-winmac-settingsThe following topics are included in this section:To configure the integration of FortiGate SSL VPN into Azure AD. Layer 2 Tunneling Protocol (L2TP)L2TP is a tunneling protocol published in 1999 that is used with VPNs, as the name suggests. Starting in FortiOS 4.0 MR2, you can configure a FortiGate unit to work with unmodified Microsoft VPN client software. Example FortiGate VPN configuration with Microsoft clientsFor users, the difference is that instead of installing and using the FortiClient application, they configure a network connection using the software built into the Microsoft Windows operating system. The topology of a VPN for Microsoft Windows dialup clients is very similar to the topology for FortiClient Endpoint Security clients. Generally known as a free VPN solution, Fortinet Vpn Client For Mac Hotspot Shield attracts users via its free-of-charge plan. However, in Mac OSX (OSX 10.6.3, including patch releases) the L2TP feature does not work properly on the Mac OS side. The initiator of the L2TP tunnel is called the L2TP Access Concentrator (LAC).L2TP and IPsec is supported for native Windows XP, Windows Vista and Mac OSX native VPN clients. IPsec is used to secure L2TP packets. Mac OS X 10.3 system and higher also have a built-in client.L2TP provides no encryption and used UDP port 1701. Configure LT2P users and firewall user group. Configuring the FortiGate unitTo configure the FortiGate unit, you must: User has Microsoft Windows 2000 or higher — a Windows version that supports L2TPThe following section consists of configuring the FortiGate unit and configuring the Windows PC. L2TP protocol traffic is allowed through network firewalls (TCP and UDP port 1701) Fortinet Vpn Client Password Defined OnCreating a user account – web-based manager You might want to use these for their L2TP user name and password. The Microsoft VPN client can automatically send the user’s Window network logon credentials. Creating user accountsYou need to create user accounts and then add these users to a firewall user group to be used for L2TP authentication. The authentication process can use a password defined on the FortiGate unit or an established external authentication mechanism such as RADIUS or LDAP. Configure an IPsec VPN with encryption and authentication settings that match the Microsoft VPN client.Configuring LT2P users and firewall user groupRemote users must be authenticated before they can request services and/or access network resources through the VPN. Increase menu font size in outlook for macCreating a user group – web-based manager You need to create a firewall user group to use for this purpose. The authentication server must be already configured on the FortiGate unit.To create a user account called user1 with the password 123_user, enter:Config user local edit user1 set type password set passwd “123_user” set status enableWhen clients connect using the L2TP-over-IPsec VPN, the FortiGate unit checks their credentials against the user group you specify for L2TP authentication. L Select Match user on LDAP server, Match user on RADIUS server, or Match user onTACACS+Server and select the authentication server from the list. Configuring IPsecThe Microsoft VPN client uses IPsec for encryption. For example,Config firewall address edit L2TPclients set type iprange set start-ip 192.168.0.50 set end-ip 192.168.0.59Alternatively, you could define this range in the web-based manager. For example, to allow access to users in the L2TP_group and assign them addresses in the range 192.168.0.50 to 192.168.0.59, enter:Config vpn l2tp set sip 192.168.0.50 set eip 192.168.0.59 set status enable set usrgrp “L2TP_group”One of the security policies for the L2TP over IPsec VPN uses the client address range, so you need also need to create a firewall address for that range. As well as enabling L2TP, you set the range of IP address values that are assigned to L2TP clients and specify the user group that can access the VPN. To remove a member, select the name and then select the left arrow button.To create the user group L2TP_group and add members User_1, User_2, and User_3, enter:Config user group edit L2TP_group set group-type firewall set member User_1 User_2 User_3 endYou can only configure L2TP settings in the CLI. To add a member to this list, select the name and then select the right arrow button.The list of Local users, RADIUS servers, LDAP servers, TACACS+ servers, or PKI users that belong to the user group. Revit download for macEdit the Phase 1 Proposal (if it is not available, you may need to click the Convert to Custom Tunnel button).Enter a name for this VPN, dialup_p1 for example.Select the network interface that connects to the Internet. Go to VPN > IPsec Tunnels and create the new custom tunnel or edit an existing tunnel. Configuring Phase 1 – web-based manager The encryption and authentication proposals must be compatible with the Microsoft client.L2TP over IPsec is supported on the FortiGate unit for both policy-based and route-based configurations, but the following example is policy-based. Transport mode is used instead of tunnel mode. Make this a transport-mode VPN. Enter the following information and then select OK. Configuring Phase 2 – web-based manager This key must also be entered in the Microsoft VPN client.Select Advanced to enter the following information.Enter the following Encryption/Authentication pairs:To create a Phase 1 configuration called dialup_p1 on a FortiGate unit that has port1 connected to the Internet, you would enter:Config vpn ipsec phase1 edit dialup_p1 set type dynamic set interface port1 set mode main set psksecret ********Set proposal aes256-md5 3des-sha1 aes192-sha1 set dhgrp 2 set nattraversal enableIt is worth noting here that the command config vpn ipsec phase1 is used rather than config vpn ipsec phase1-interface because this configuration is policy-based and not route-based. Go to Policy & Objects > IPv4 Policy and select Create New. Go to System > Feature Visibility and enable Policy-based IPsec VPN. A regular ACCEPT policy to allow traffic from the L2TP clients to access the protected networkConfiguring the IPsec security policy – web-based manager An IPsec policy, as you would create for any policy-based IPsec VPN Configuring security policiesThe security policies required for L2TP over IPsec VPN are: If your Phase 2 name is dialup_p2, you would enter:Config vpn ipsec phase2 edit dialup_p2 set encapsulation transport-modeTo configure a Phase 2 to work with your phase_1 configuration, you would enter:Config vpn ipsec phase2 edit dialup_p2 set phase1name dialup_p1Set proposal aes256-md5 3des-sha1 aes192-sha1 set replay enable set pfs disable set keylifeseconds 3600 set encapsulation transport-modeOnce again, note here that the command config vpn ipsec phase2 is used rather than config vpn ipsec phase2-interface because this configuration is policy-based and not route-based.
