Update GRE configuration with dynamic addresses
===============================================
[⬅️ Go back to main README](../README.md)
> ℹ️ **Info**: This script can not be used on its own but requires the base
> installation. See [main README](../README.md) for details.
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:
/interface/gre/set comment="ikev2-client1" gre-client1;
