To configure IPsec VPN with FortiClient as the dialup client using the CLI:

  1. In the FortiOS CLI, configure the user, user group, and firewall address by running the following commands. Only the HQ dialup server FortiGate needs this configuration. The address is an IP pool to assign an IP address for the dialup client FortiGate.

config user local edit “vpnuser1” set type password set passwd your-password

next

end config user group edit “vpngroup” set member”vpnuser1″

next

end

config firewall address

edit “client_range” set type iprange set start-ip 10.10.10.1 set end-ip 10.10.10.200

next

end

  1. Configure the WAN interface and default route. The WAN interface is the interface connected to the ISP. It can work in static mode (as shown in the example), DHCP, or PPPoE mode. The IPsec tunnel is established over the WAN interface:
  2. Configure the HQ FortiGate:

config system interface edit “wan1” set vdom “root” set ip 11.101.1 255.255.255.0

next

end

config router static edit 1 set gateway 11.101.1.2 set device “wan1”

next

end

  1. Configure the branch office FortiGate:

config system interface edit “port13” set vdom “root” set ip 173.1.1.1 255.255.255.0

next

end

config router static edit 1 set gateway 173.1.1.2 set device “port13”

next

end

  1. Configure the internal interface and protected subnet. The internal interface connects to the internal network.

Traffic from this interface will route out the IPsec VPN tunnel: a. Configure the HQ FortiGate:

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

set ip 10.1.100.1 255.255.255.0

next

end

config firewall address edit “10.1.100.0” set subnet 10.1.100.0 255.255.255.0

next end

  1. Configure the branch office FortiGate:

config system interface edit “port9” set vdom “root”

set ip 172.16.101.1 255.255.255.0

next

end

config firewall address edit “172.16.101.0” set subnet 172.16.101.0 255.255.255.0

next

end

  1. Configure the IPsec phase1-interface. In this example, PSK is used as the authentication method. Signature authentication is also an option:
  2. Configure the HQ FortiGate:

config vpn ipsec phase1-interface edit “for_Branch” set type dynamic set interface “wan1” set mode aggressive set peertype any set mode-cfg enable

set proposal aes128-sha256 aes256-sha256 aes128-sha1 aes256-sha1 set add-route disable set dpd on-idle set xauthtype auto set authusrgrp “vpngroup” set net-device enable set assign-ip-from name set dns-mode auto set ipv4-split-include “10.1.100.0” set ipv4-name “client_range” set save-password enable set psksecret sample set dpd-retryinterval 60

next

end

  1. Configure the branch office FortiGate:

config vpn ipsec phase1-interface edit “to_HQ” set interface “port13” set mode aggressive set peertype any set mode-cfg enable

set proposal aes128-sha256 aes256-sha256 aes128-sha1 aes256-sha1 set add-route disable set xauthtype client set authusr “vpnuser1” set authpasswd vpnuser1-password set remote-gw 11.101.1.1 set psksecret sample

next end

  1. Configure the IPsec phase2-interface:
    1. Configure the HQ FortiGate:

config vpn ipsec phase2-interface edit “for_Branch_p2” set phase1 name “for_Branch”

set proposal aes128-sha1 aes256-sha1 aes128-sha256 aes256-sha256 aes128gcm

aes256gcm chacha20poly1305 next

end

  1. Configure the branch office FortiGate:

config vpn ipsec phase2-interface edit “to_HQ_p2” set phase1name “to_HQ”

set proposal aes128-sha1 aes256-sha1 aes128-sha256 aes256-sha256 aes128gcm

aes256gcm chacha20poly1305 next

end

  1. Configure the static routes on the branch office FortiGate. The blackhole route is important to ensure that IPsec traffic does not match the default route when the IPsec tunnel is down:

config router static edit 2 set dst 10.1.100.0 255.255.255.0 set device “to_HQ”

next edit 3 set dst 10.1.100.0 255.255.255.0 set blackhole enable set distance 254

next

end

  1. Configure the firewall policy to allow the branch office to HQ network flow over the IPsec tunnel. This configuration only supports traffic from the branch office FortiGate to the HQ FortiGate. Traffic is dropped from the HQ FortiGate to the branch office FortiGate:
  2. Configure the HQ FortiGate:

config firewall policy edit 1 set name “inbound” set srcintf “for_Branch” set dstintf “dmz” set srcaddr “172.16.101.0” set dstaddr “10.1.100.0” set action accept set schedule “always” set service “ALL”

next

end

  1. Configure the branch office FortiGate:

config firewall policy edit 1 set name “outbound”

set srcintf “port9” set dstintf “to_HQ” set srcaddr “172.16.101.0” set dstaddr “10.1.100.0” set action accept set schedule “always” set service “ALL”

next

end

  1. Run diagnose commands. These diagnose commands are useful to check the IPsec phase1/phase2 interface status. The diagnose debug application ike -1 command is the key to figure out why the IPsec tunnel failed to establish.
  2. Run the diagnose vpn ike gateway list command on the HQ FortiGate. The system should return the following:

end

  1. Configure the client address pool. You must create a firewall address to assign an IP address to a client from the address pool.

config firewall address edit “client_range” set type iprange set comment “VPN client range” set start-ip 10.10.2.1 set end-ip 10.10.2.200

next

end

  1. Configure the IPsec phase1-interface. In this example, PSK is used as the authentication method. Signature authentication is also an option.

config vpn ipsec phase1-interface edit “for_ios_p1” set type dynamic set interface “wan1” set peertype any set net-device enable set mode-cfg enable

set proposal aes256-sha256 aes256-md5 aes256-sha1 set dpd on-idle set dhgrp 14 5 2 set xauthtype auto set authusrgrp “vpngroup” set assign-ip-from name set ipv4-name “client_range” set dns-mode auto

set ipv4-split-include “local_network” set psksecret your-psk set dpd-retryinterval 60

next

end

  1. Configure the IPsec phase2-interface:

config vpn ipsec phase2-interface edit “for_ios_p2” set phase1name “for_ios_p1”

set proposal aes128-sha1 aes256-sha1 aes128-sha256 aes256-sha256 aes128gcm

aes256gcm chacha20poly1305 set pfs disable set keepalive enable

next

end

  1. Configure the firewall policy to allow client traffic flow over the IPsec VPN tunnel:

config firewall policy edit 1 set name “ios_vpn” set srcintf “for_ios_p1” set dstintf “lan” set srcaddr “ios_range” set dstaddr “local_network” set action accept set schedule “always” set service “ALL”

next

end

  1. Configure the iOS device:
    1. In the iOS device, go to Settings > General > VPN and select Add VPN Configuration.
    2. Set the Type to IPsec and enter a Description. Set the Server to the FortiGate’s Internet-facing interface, and enter the username in Account. Enter the user password, the preshared IPsec VPN secret, then select Done.
    3. Ensure that the IPsec VPN configuration is highlighted (indicated by a checkmark), and select the Not Connected The IPsec VPN connects with the user’s credentials and secret. The status changes to Connected, and a VPN icon appears at the top of the screen.
  2. Run diagnose These diagnose commands are useful to check the IPsec phase1/phase2 interface status. The diagnose debug application ike -1 command is the key to figure out why the IPsec tunnel failed to establish.
    1. Run the diagnose vpn ike gateway list The system should return the following:

vd: root/0 name: for_ios_p1_0 version: 1 interface: port1 15 addr: 172.20.120.123:4500 -> 172.20.120.254:64916 created: 17s ago xauth-user: u1 assigned IPv4 address: 10.10.2.1/255.255.255.255 nat: me peer

  1. Run the diagnose vpn tunnel list The system should return the following:

One thought on “Dialup VPN Options”

  1. Allen Unrau

    I really dislike Fortinet’s use of the term “dialup” to refer to mobile clients. It’s confusing. To me, the term “dialup” refers to using a modem over Plain-Old-Telephone-Service. I can’t even read the term without hearing the screech of audible modem negotiations in my head!
