SSL VPN split tunnel for remote user

This topic provides a sample configuration of remote users accessing the corporate network and internet through an SSL VPN by tunnel mode using FortiClient but accessing the Internet without going through the SSL VPN tunnel.

Sample network 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.

Port1 interface connects to the internal network.

1. Go to Network > Interface and edit the wan1
2. Set IP/Network Mask to 20.120.123/255.255.255.0.
3. Edit port1 interface and set IP/Network Mask to 168.1.99/255.255.255.0.
4. Click OK.
5. Go to Firewall & Objects > Address and create an address for internet subnet 168.1.0.
6. Configure user and user group.
   1. Go to User& Device > UserDefinition to create a local user sslvpnuser1.
   2. Go to User& Device > UserGroups to create a group sslvpngroup with the member sslvpnuser1.
7. Configure SSL VPN web portal.
   1. Go to VPN > SSL-VPN Portals to create a tunnel mode only portal my-split-tunnel-portal. Enable Split Tunneling.
   2. Select Routing Address. 4. Configure SSL VPN settings.
   3. Go to VPN > SSL-VPN Settings.
   4. Choose proper Listen on Interface, in this example, wan1.
   5. Listen on Port 10443.
   6. Choose a certificate for ServerCertificate. The default is Fortinet_Factory.
   7. Under Authentication/Portal Mapping, set default Portal tunnel-access for All OtherUsers/Groups.
   8. Create new Authentication/Portal Mapping for group sslvpngroup mapping portal my-split-tunnel-portal.
   9. Configure SSL VPN firewall policy.
8. Go to Policy & Objects > IPv4 Policy.
9. Fill in the firewall policy name. In this example: sslvpn split tunnel access.
10. Incoming interface must be SSL-VPN tunnel interface(ssl.root).
11. Choose an Outgoing Interface. In this example: port1.
12. Set the source to all and group to sslvpngroup.
13. In this example, the destination is all.
14. Set schedule to always, service to ALL, and Action to Accept.
15. 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

Configure internal interface and protected subnet. Connect Port1 interface to internal network.

config system interface edit “port1” set vdom “root”

set ip 192.168.1.99 255.255.255.0

next

end

config firewall address edit “192.168.1.0” set subnet 192.168.1.0 255.255.255.0

next

end

2. 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

3. Configure SSL VPN web portal.

config vpn ssl web portal edit “my-split-tunnel-portal” set tunnel-mode enable set split-tunneling enable

set split-tunneling-routing-address “192.168.1.0” set ip-pools “SSLVPN_TUNNEL_ADDR1”

next

end

4. 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-split-tunnel-portal”

next

end

5. Configure SSL VPN firewall policy.

Configure one 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 “192.168.1.0” set groups “sslvpngroup” set action accept set schedule “always” set service “ALL”

next

end

To see the results:

1. Download FortiClient from forticlient.com.
2. Open the FortiClient Console and go to Remote Access.
3. Add a new connection.

l Set VPN Type to SSL VPN. l 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, traffic to 168.1.0 goes through the tunnel. Other traffic goes through local gateway.
8. In FGT, 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.
