IPsec between pfSense and edgerouter

[plopes]

Hi all!

Sorry, but I'm new in pfSense world :)

I setup a vpn ipsec between pFsense and Edgerouter (both fqdn) and is up and running for a long while. Allmost a week with no issues...

However, yesterday, my pfsense ip fqdn has changed.

I had to restart manually both routers - pfSense and the edgerouter.

Any help in order to "restart" the tunnel when ip from the fqdn changes?

TIA
