I use the native Windows VPN clients when connecting to the VPN over IKEv2. If i want split routing without configuring manually anything, i need to forward the DHCP request to the DHCP-server (Windows VPN client sends a DHCP request upon connection and add routes supplied in option 249 of the DHCP reply). This can only be achieved with the strongswan's dhcp plugin.
DHCP plugin is now succesfully ported to FreeBSDs Strongswan and available in the version 5.9.14 https://github.com/strongswan/strongswan/releases/tag/5.9.14 (https://github.com/strongswan/strongswan/releases/tag/5.9.14).
If there is a plan to add the strongswan dhcp plugin to OPNSense?
I'm confused... Is it hard to implement or is it just that no one wants this feature?
Did you open a feature request on github?
No, if that's what needs to be done to get an official answer, I'll do it.
Please do.
I created an issue on GitHub
