How can I get this VPN setup to work? :)

Ok I’ve gotten this to work with 100% mikrotik. Unfortunately I’m forced to use PFSense for the ipsec server at HQ.
Site to multi site. 1 HQ multiple remote sites.
I need to be able to access all these remote sites from HQ.
In mikrotik I was able to setup L2TP/IPSec and use secrets with the route field filled out (IE: 10.0.0.1 172.16.32.5 1) that would add a route to the server’s table. When a remote site connects, it adds it’s local subnet to the ipsec servers route table and everyone in HQ can talk to everyone at the remote sites subnet just fine.


How can I connect to my PFSense ipsec server so that it will add the remote sites subnet to it’s route table with my mikrotik?
