4.12 IPsec Tunnel Configuration
The IPsec tunnel function allows you to create a secured connection between two separate
LAN networks. Advantech routers allows you to create up to four IPsec tunnels.
To open the IPsec tunnel configuration page, click IPsec in the Configuration section of the
main menu. The menu item will expand and you will see four separate configuration pages:
1st Tunnel, 2nd Tunnel, 3rd Tunnel and 4th Tunnel. Supported are both, policy-based and
route-based VPN approaches, see the different configuration scenarios in Chapter 4.12.1.
IPv4 and IPv6 tunnels are supported (dual stack), you can transport IPv6 traffic through
IPv4 tunnel and vice versa. For different IPsec authentication scenarios, see Chapter 4.12.2.
To encrypt data between the local and remote subnets, specify the appropriate values in
the subnet fields on both routers. To encrypt the data stream between the routers only,
leave the local and remote subnets fields blank.
If you specify the protocol and port information in the Local Protocol/Port field, then the
router encapsulates only the packets matching the settings.
For optimal an secure setup, we recommend to follow instructions on the Security Rec-
ommendations strongSwan web page.
Detailed information and more examples of IPsec tunnel configuration and authentication can
be found in the application note IPsec Tunnel [6].
FRRouting (FRR) router app is an Internet routing protocol suite for Advantech routers. This
UM includes protocol daemons for BGP, IS-IS, LDP, OSPF, PIM, and RIP.
4.12.1 Route-based Configuration Scenarios
There are more different route-based configuration options which can be configured and
used in Advantech routers. Below are listed the most common cases which can be used (for
more details see Route-based VPNs strongSwan web page):
1. Enabled Installing Routes
• Remote (local) subnets are used as traffic selectors (routes).
• It results to the same outcome as a policy-based VPN.
• One benefit of this approach is the possibility to verify non-encrypted traffic passed
through an IPsec tunnel number X by tcdump tool:
• Set up the Install Routes to yes option.
