Server via pfsense with multiple wan

[pietersnld]

Hi,

I have an openvpn client to connect to our main office. Main office has an openvpn server behind a pfsense firewall with mutiple wan connections. All is working fine. If primary wan goes down client connects to backup wan. Problem is that if the primary wan comes back again client stays connected to backup wan. Using a no-ip.biz adress for the main office. Resolves to the fastest available wan connection.
How can i make the client resolve the fqdn again and reconnect if address changes?

Greetings,
Pieter
