[strongSwan] Framed-Ip-Address not sent to client?

[Laurens Vets]

Hello list,

I have a strongSwan setup with a Freeradius backend. Currently, only 
authentication with Radius works. I've now set up Freeradius to also 
give out ip addresses via Framed-Ip-Address. This seems to according to 
the Radius logs.

When I change "rightsourceip=10.0.0.0/24" to "rightsourceip=%radius", 
strongSwan is still giving out ip addresses from that initial pool 
instead of using the Framed-Ip-Address (they are different subnets):

Any idea what I might be missing?
