Example Adding secure tunneling to an active-passive WAN optimization configuration

Example Adding secure tunneling to an active-passive WAN optimization configuration

This example shows how to configure two FortiGate units for active-passive WAN optimization with secure tunneling. The same authentication group is added to both FortiGate units. The authentication group includes a password (or pre-shared key) and has Peer Acceptance set to Accept any Peer. An active policy is added to the client-side FortiGate unit and a passive policy to the server-side FortiGate unit. The active policy includes a profile that performs secure tunneling, optimizes HTTP traffic, and uses Transparent Mode and byte caching.

The authentication group is named Auth-Secure-Tunnel and the password for the pre-shared key is 2345678. The topology for this example is shown below. This example includes web-based manager configuration steps followed by equivalent CLI configuration steps. For information about secure tunneling, see Secure tunneling on page 1.

Network topology and assumptions

This example configuration includes a client-side FortiGate unit called Client-net with a WAN IP address of 172.30.120.1.This unit is in front of a network with IP address 172.20.120.0. The server-side FortiGate unit is called Web-servers and has a WAN IP address of 192.168.20.1. This unit is in front of a web server network with IP address 192.168.10.0.

General configuration steps

This section breaks down the configuration for this example into smaller procedures. For best results, follow the procedures in the order given:

1. Configure the client-side FortiGate unit:
   • Add peers. l Add an authentication group. l Add an active WAN optimization policy.
2. Configure the server-side FortiGate unit. l Add peers.
   • Add the same authentication group l Add a passive WAN optimization policy that applies application control. l Add a WAN optimization tunnel policy.

Also note that if you perform any additional actions between procedures, your configuration may have different results.

Configuring WAN optimization with secure tunneling – web-based manager

Use the following steps to configure the example WAN optimization configuration from the client-side and serverside FortiGate unit web-based manager. (CLI steps follow.)

To configure the client-side FortiGate unit

1. Go to WAN Opt. & Cache > Peersand enter a Local Host ID for the client-side FortiGate unit:

2. Select Apply to save your setting.
3. Select Create New and add a Peer Host ID and the IP Address for the server-side FortiGate unit:

4. Select OK.
5. Go to WAN Opt. & Cache > Authentication Groups and select Create New to add the authentication group to be used for secure tunneling:

6. Select OK.
7. Go to WAN Opt. & Cache > Profiles and select Create New to add a WAN optimization profile that enables secure tunneling and includes the authentication group:

8. Select the HTTP protocol, select Secure Tunneling and Byte Caching and set the Port to 80.
9. Select OK.
10. Go to Policy & Objects > Addresses and select Create New to add a firewall address for the client network.

11. Select Create New to add a firewall address for the web server network.

12. Go to Policy & Objects > IPv4 Policy and select Create New to add an active WAN optimization security policy:

13. Turn on WAN Optimization and configure the following settings:

14. Select OK.

To configure the server-side FortiGate unit

1. Go to WAN Opt. & Cache > Peersand enter a Local Host ID for the server-side FortiGate unit:

2. Select Apply to save your setting.
3. Select Create New and add a Peer Host ID and the IP Address for the client-side FortiGate unit:

4. Select OK.
5. Go to WAN Opt. & Cache > Authentication Groups and select Create New and add an authentication group to be used for secure tunneling:

6. Select OK.
7. Go to Policy & Objects > Addresses and select Create New to add a firewall address for the client network.

8. Select Create New to add a firewall address for the web server network.

9. Select OK.
10. Select Create New to add a passive WAN optimization policy that applies application control.

11. Turn on WAN Optimization and configure the following settings:

12. Select OK.
13. From the CLI enter the following command to add a WAN optimization tunnel explicit proxy policy. configure firewall proxy-policy edit 0 set proxy wanopt set dstintf port1 set srcaddr all set dstaddr all set action accept set schedule always set service ALL

next

end

Configuring WAN optimization with secure tunneling – CLI

Use the following steps to configure the example WAN optimization configuration from the client-side and serverside FortiGate unit CLI.

To the client-side FortiGate unit

1. Add the Local Host ID to the client-side FortiGate configuration:

config wanopt settings set host-id Client-Fgt

end

2. Add the server-side Local Host ID to the client-side peer list:

config wanopt peer edit Server-Fgt set ip 192.168.20.1

end

3. Add a new authentication group to be used for secure tunneling:

config wanopt auth-group edit Auth-Secure-Tunnel set auth-method psk set psk 2345678

end

Leave peer-accept at its default value.

4. Add a WAN optimization profile that enables secure tunneling and includes the authentication group, enables HTTP protocol optimization, and enables secure tunneling and byte caching for HTTP traffic:

config wanopt profile edit Secure-wan-op-pro set auth-group Auth-Secure-Tunnel config http set status enable set secure-tunnel enable set byte-caching enable set port 80 end

end

5. Add a firewall address for the client network.

config firewall address edit Client-Net set type ipmask set subnet 172.20.120.0 255.255.255.0 set associated-interface port1

end

6. Add a firewall address for the web server network.

config firewall address edit Web-Server-Net set type ipmask set subnet 192.168.10.0 255.255.255.0 set associated-interface port2

end

7. Add an active WAN optimization security policy that includes the WAN optimization profile that enables secure tunneling and that applies virus scanning:

config firewall policy edit 0 set srcintf port1 set dstintf port2 set srcaddr Client-Net set dstaddr Web-Server-Net set action accept set service HTTP set schedule always set wanopt enable set wanopt-detection active set wanopt-profile Secure-wan-opt-pro

end

To configure the server-side FortiGate unit

1. Add the Local Host ID to the server-side FortiGate configuration:

config wanopt settings set host-id Server-Fgt

end

2. Add the client-side Local Host ID to the server-side peer list:

config wanopt peer edit Client-Fgt set ip 172.20.120.1

end

3. Add an authentication group to be used for secure tunneling: config wanopt auth-group edit Auth-Secure-Tunnel set auth-method psk set psk 2345678

end

Leave peer-accept at its default value.

4. Add a firewall address for the client network. config firewall address edit Client-Net set type ipmask set subnet 172.20.120.0 255.255.255.0 set associated-interface port1

end

5. Add a firewall address for the web server network. config firewall address edit Web-Server-Net set type ipmask set subnet 192.168.10.0 255.255.255.0 set associated-interface port2

end

• Add a passive WAN optimization policy. config firewall policy edit 0 set srcintf port1 set dstintf port2 set srcaddr Client-Net set dstaddr Web-Server-Net set action accept set service ALL set schedule always set wanopt enable set wanopt-detection passive set wanopt-passive-opt default

end

7. Add a WAN optimization tunnel explicit proxy policy. configure firewall proxy-policy edit 0 set proxy wanopt set dstintf port1 set srcaddr all set dstaddr all set action accept set schedule always set service ALL

next end
