Do not route DDNS through OpenVPN client

[dvs23]

Hey!

I run an OpenVPN client and server simultaneously on my pfsense machine. To access the OpenVPN server from outside, I use a No-IP DDNS which is automatically updated by my pfsense machine. But once I activate the OpenVPN client, the DDNS update client uses the new public IP of the VPN tunnle to update the DDNS. As a result I cannot access my OpenVPN server after the first update. So I somehow need to exclude the DDNS client from the tunnle, so it can fetch my real public IP. How can I do this?

Thanks in advance

Edit: Pfsense seems to be already that smart! It was a second client updating the DDNS which set the wrong IP :)
