IPsec Client plugin
The 128T-ipsec-client plugin provides a way to send and encrypt traffic to IPsec endpoints through the SSR. It is possible to configure the plugin for each router to have multiple destination IPsec endpoints and thus the SSR will failover between them. This is accomplished by performing a Service Function Chain (SFC) with Libreswan, a third-party IPsec client. By enabling this plugin, you can provide IPsec tunnel connectivity to third party providers from your SSR.
The instructions for installing and managing the plugin can be found here.
Configuration
The IPsec plugin setup has the following key parts to the configuration.
ipsec-profiledescribing the mechanism with which to connect to the server.ipsec-clientrepresent the remote endpoints or server with which the ipsec client communicates.service-route's to route the traffic through the tunnels
Profiles
The router > ipsec-profile's are reusable IPsec settings that can be used across multiple nodes in a router and multiple IPsec endpoint remotes. The table below represents the most common configuration elements for a valid ipsec profile.
router
ipsec-profile zscaler
name zscaler
ike-encryption aes256
ike-digest sha2
ike-modp modp1024
authentication-protocol esp
phase2-encryption aes_gcm128
phase2-digest sha2
phase2-modp modp1024
ike-lifetime 1h
connection-lifetime 8h
perfect-forward-secrecy true
dpddelay 20
dpdtimeout 100
dpdaction restart
local-id [local-id@domain.com]

Custom Options
Version History
| Release | Modification |
|---|---|
| 3.3.0 | profile > custom-option introduced |
The custom-option allows the user to configure additional obscure libreswan options that are not exposed via the profile and remote configuration.
config
authority
router myRouter
name myRouter
ipsec-profile myProfile
name myProfile
custom-option key
name key
value value
exit
exit
exit
exit
exit
| Config | Description |
|---|---|
| name | The name of the libreswan option |
| value | The value of the option |
The custom-option is added to the libreswan config file; any invalid option could prevent the application from starting up.
Clients
Clients are a collection of remote endpoints which can be used for connection and failover purposes.
The main config properties of a remote endpoint are as follows.
| Config | Type | Description |
|---|---|---|
| name | string | The name of the remote client to be used for sending traffic to the tunnel. |
| host | ip-or-fqdn | The address or FQDN of the remote endpoint. |
| profile | reference | The name of the profile to be used for this remote endpoint. |
| remote-id | string | The optional remote identifier used during authentication. |
| subnet | ip-prefix | The remote subnet behind the tunnel. |
| tunnel-monitor | container | Properties for monitoring the phase-2 connection. See Tunnel Monitoring for more information. |
Example:
router myRouter
node
name myRouter
ipsec-client client1
name client1
enabled true
tenant ipsec
remote primary
name primary
host <primary-address>
profile myProfile
remote-id prisma@paloalto.com
subnet 0.0.0/0
tunnel-monitor
enabled true
destination 8.8.8.8
address 8.8.8.8
timeout 10
max-retries 3
interval 60
exit
exit
exit
remote secondary
name primary
host <primary-address>
profile myProfile
remote-id prisma@paloalto.com
subnet 0.0.0/0
tunnel-monitor
enabled true
destination 8.8.8.8
address 8.8.8.8
timeout 10
max-retries 3
interval 60
exit
exit
exit
exit
exit
exit
Only one ipsec-client can be configured per node, but two remotes can be configured per client.
The ipsec-client > name cannot start with ipsec or mast. See notes here.
Each remote represents a unique tunnel destination and can be used to route traffic in/out of the tunnels. Typically each node has two tunnels to act as primary and backup.
Tunnel Monitoring
Version History
| Release | Modification |
|---|---|
| 3.2.0 | remote > tunnel-monitor introduced |
Tunnel monitoring is a way to monitor the health of individual tunnels and have them automatically restart if they become unhealthy. An ICMP ping is used for the traffic. For each remote, you can specify a destination, interval, timeout, and the number of max retries for each interval.
node
ipsec-client client1
remote c1gateway1
tunnel-monitor
enabled true
destination 8.8.8.8
address 8.8.8.8
timeout 10
max-retries 3
interval 120
exit
exit
exit
tunnel-monitor-nat-network 10.128.128.0/28
exit
exit
| Config | Description |
|---|---|
enabled | Allows you to switch tunnel monitoring on and off for a remote. |
address | The IP or hostname where traffic is sent. This address must be reachable after traversing the tunnel. |
timeout | Duration (in seconds) within which to reach the destination. Each attempt will be made in this duration / max-retries interval. |
max-retries | Number of consecutive missed ICMP ping responses from the destination within the interval before deciding that the tunnel is unhealthy. |
interval | Duration (in seconds) of how often to perform an ICMP probe test to the probe-address. |
tunnel-monitor-nat-network | The subnet where traffic originates. The corresponding ingress KNI's fourth octet is used. By default, the subnet 10.128.128.0/28 is used. |
Configuring services for tunnel traffic
The user can define up to four ipsec-client > remote endpoints per node. In addition, the user must also define the necessary service and service-routes to route the tunnel traffic over the desired WAN interface.
The following example shows a configuration for capturing the tunnel traffic and allows the ipsec tenant as defined in router > ipsec-client > tenant config above.
config
authority
service ipsec-tunnel
name ipsec-tunnel
scope private
address <remote-address-1>
address <remote-address-2>
transport udp
protocol udp
port-range 4500
start-port 4500
exit
port-range 500
start-port 500
exit
exit
access-policy ipsec
source ipsec
exit
exit
exit
exit
The <remote-address-1> and <remote-address-2> represent the node > ipsec-client > remote > host address. The ipsec tenant is allowed as per the tenant defined under ipsec-client > tenant. The user can split the tunnels into separate services per the routing requirements.
Directing traffic through the tunnel
The user can leverage standard SSR service and service-route to direct intended traffic over the ipsec tunnel. In the example below, all guest internet traffic is sent over the ipsec tunnel for break and inspect. This can be accomplished as follows:
config
authority
router myRouter
name myRouter
service-route guest-internet-rte-primary
name guest-internet-rte-primary
service-name guest-internet
next-hop combo-east-1 primary
node-name combo-east-1
interface primary
exit
exit
service-route guest-internet-rte-secondary
name guest-internet-rte-secondary
service-name guest-internet
next-hop combo-east-1 secondary
node-name combo-east-1
interface secondary
exit
exit
exit
tenant guest
name guest
exit
service guest-internet
name guest-internet
description "guest-internet access"
scope private
address 0.0.0.0/0
access-policy guest
source guest
exit
exit
exit
exit
The service-route > next-hop > interface must point to the corresponding ipsec-client > remote > name-intf to route the traffic through the tunnel. All available SSR routing techniques including using vectors, service-policy, etc., can be leveraged to define how the untrusted traffic is sent over the tunnels, and how to route the traffic. The SSR routes the packets through the appropriate IPSec tunnels and manages the failover as per the policy. On the return path, the encrypted traffic is processed, decrypted, and send back to the client that originated the session.
Redundancy
By default both nodes of an HA pair will create and maintain the tunnels configured for them.
Version History

Systemd Services
To check the status of the IPsec client service on the router, you can run show system services which will show all SSR related services running on the specified node. The one for this plugin is named 128t-ipsec.
To verify that the services are running properly on the SSR:
systemctl status 128t-ipsec@<client>.service
Failover Alarms
If a tunnel goes down, we set the corresponding ingress KNI to be operationally down. An alarm will be created when this happens.
Example output when the tunnel for rem1 goes down:

Appendix
Generated SSR Configuration
A KNI per remote is created with the name of the remote and a single egress KNI is created with the name of the ipsec-client.
User-Specific SSR Configuration
To allow the maximum flexibility on getting the traffic into the plugin's network namespace and getting the traffic out, we rely on the user to configure those means (usually through services and service routes).
You will need to have the IPsec endpoint bound traffic sent into the KNIs with the names of the remotes. You can use builtin SSR failover techniques due to the KNIs being reported operationally down when the corresponding tunnel is down. You will also need to configure a way for the traffic to be routed towards the IPsec endpoint after being encrypted. All of this encrypted traffic will be assigned to the tenant configured under ipsec-client.

Issues Fixed
PLUGIN-1999 Tunnels failed to come up because of unresolvable DNS during startup
Resolution: The salt application no longer requires DNS to generate libreswan configuration.
PLUGIN-1906 DNS Proxy services were not being used for ipsec hostname resolution
Resolution The plugin now automatically adds the configured ipsec tenant to dns-proxy services.
PLUGIN-1782 Removing destinations from tunnel monitoring config causes invalid configuration
Resolution The configuration validation now accepts this configuration flow
