SSL VPN full tunnel for remote user

This is a sample configuration of remote users accessing the corporate network and internet through an SSL VPN by tunnel mode using FortiClient.

Sample topology

Sample configuration

WAN interface is the interface connected to ISP. This example shows static mode. You can also use DHCP or PPPoE mode. The SSL VPN connection is established over the WAN interface.

To configure SSL VPN using the GUI:
  1. Configure the interface and firewall address. The port1 interface connects to the internal network.
    1. Go to Network > Interfaces and edit the wan1 interface.
    2. Set IP/Network Mask to 172.20.120.123/255.255.255.0.
    3. Edit port1 interface and set IP/Network Mask to 192.168.1.99/255.255.255.0.
    4. Click OK.
  2. Configure user and user group.
    1. Go to User & Device > User Definition to create a local user sslvpnuser1.
    2. Go to User & Device > User Groups to create a group sslvpngroup with the member sslvpnuser1.
  3. Configure SSL VPN web portal.
    1. Go to VPN > SSL-VPN Portals to create a tunnel mode only portal my-full-tunnel-portal.
    2. Disable Split Tunneling.
  4. Configure SSL VPN settings.
    1. Go to VPN > SSL-VPN Settings.
    2. For Listen on Interface(s), select wan1.
    3. Set Listen on Port to 10443.
    4. Choose a certificate for Server Certificate. The default is Fortinet_Factory.
    5. In Authentication/Portal Mapping All Other Users/Groups, set the Portal to tunnel-access.
    6. Create new Authentication/Portal Mapping for group sslvpngroup mapping portal my-full-tunnel-portal.
  5. Configure SSL VPN firewall policy.
    1. Go to Policy & Objects > IPv4 Policy.
    2. Fill in the firewall policy name. In this example, sslvpn full tunnel access.
    3. Incoming interface must be SSL-VPN tunnel interface(ssl.root).
    4. Choose an Outgoing Interface. In this example, port1.
    5. Set the Source to all and group to sslvpngroup.
    6. In this example, the Destination is all.
    7. Set Schedule to always, Service to ALL, and Action to Accept.
    8. Click OK.
To configure SSL VPN using the CLI:
  1. Configure the interface and firewall address.
    config system interface 
        edit "wan1"
            set vdom "root"
            set ip 172.20.120.123 255.255.255.0
        next
    end
  2. Configure the internal interface and protected subnet, then connect the port1 interface to the internal network.
    config system interface
        edit "port1"
            set vdom "root"
            set ip 192.168.1.99 255.255.255.0
        next
    end
  3. Configure user and user group.
    config user local
        edit "sslvpnuser1" 
            set type password
            set passwd your-password
        next 
    end
    config user group
        edit "sslvpngroup" 
            set member "vpnuser1"
        next 
    end
  4. Configure SSL VPN web portal and predefine RDP bookmark for windows server.
    config vpn ssl web portal
        edit "my-full-tunnel-portal"
            set tunnel-mode enable
            set split-tunneling disable
            set ip-pools "SSLVPN_TUNNEL_ADDR1"
        next
    end
  5. Configure SSL VPN settings.
    config vpn ssl settings
        set servercert "Fortinet_Factory"
        set tunnel-ip-pools "SSLVPN_TUNNEL_ADDR1"
        set tunnel-ipv6-pools "SSLVPN_TUNNEL_IPv6_ADDR1"
        set source-interface "wan1"
        set source-address "all"
        set source-address6 "all"
        set default-portal "full-access"
        config authentication-rule
            edit 1
                set groups "sslvpngroup"
                set portal "my-full-tunnel-portal"
            next        
    end
  6. Configure one SSL VPN firewall policy to allow remote user to access the internal network. Traffic is dropped from internal to remote client.
    config firewall policy 
        edit 1
            set name "sslvpn web mode access"
            set srcintf "ssl.root"
            set dstintf "port1"
            set srcaddr "all"
            set dstaddr "all"
            set groups “sslvpngroup”
            set action accept
            set schedule "always"
            set service "ALL"
        next
    end
To see the results:
  1. Download FortiClient from www.forticlient.com.
  2. Open the FortiClient Console and go to Remote Access.
  3. Add a new connection.
    • Set VPN Type to SSL VPN.
    • Set Remote Gateway to the IP of the listening FortiGate interface, in this example, 172.20.120.123.
  4. Select Customize Port and set it to 10443.
  5. Save your settings.
  6. Use the credentials you've set up to connect to the SSL VPN tunnel.
  7. After connection, all traffic except the local subnet will go through the tunnel FGT.
  8. Go to VPN > Monitor > SSL-VPN Monitor to verify the list of SSL users.
  9. In FGT, go to Log & Report > Traffic Log > Forward Traffic and view the details for the SSL entry.
