Description
|
|
|
|
|
|
-----------
|
|
|
|
|
|
|
|
|
|
|
|
Running a GRE tunnel over IPSec with IKEv2 is a common scenario. This is
|
|
|
|
|
|
easy to configure on client, but has an issue on server side: client IP
|
|
|
|
|
|
addresses are assigned dynamically via mode-config and have to be updated
|
|
|
|
|
|
for GRE interface.
|
|
|
|
|
|
|
|
|
|
|
|
This script handles the address updates and disables the interface if the
|
|
|
|
|
|
client is disconnected.

Requirements and installation
|
|
|
|
|
|
-----------------------------
|
|
|
|
|
|
|
|
|
|
|
|
Just install the script:
|
|
|
|
|
|
|
|
|
|
|
|
$ScriptInstallUpdate update-gre-address;
|
|
|
|
|
|
|
|
|
|
|
|
... and add a scheduler to run the script periodically:
|
|
|
|
|
|
|

|
|
|
|
/system/scheduler/add interval=30s name=update-gre-address on-event="/system/script/run update-gre-address;" start-time=startup;

|
Configuration
|
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
|
|
The configuration goes to interface's comment. Add the client's IKEv2
|
|
|
|
|
|
certificate CN into the comment:
|
|
|
|
|
|
|
2022-05-11 10:31:03 +02:00
|
|
|
|
/interface/gre/set comment="ikev2-client1" gre-client1;
|
