Create new session to flush session data

[simmarn]

Hi.
I have set up a Wireguard client to my VPN provider using pfSense 2.5.2.
It works very well and seems stable during the few days I have had it running.

The problem with my VPN provider, and I guess most providers, is that the session data contains the mapping between the external IP address and my IP address. My VPN providers deletes this data as soon as the session is closed (I guess after no handshake during 3 minutes).

The session set up with pfSense runs forever. This means that the external IP address is never changed.

I have observed that if I stop Wireguard service for a couple of minutes, I get a new external IP when I start again.

Is there some easy way in pfSense to force IP renewal for client or at least automatically stop and start service at a regular interval?
