creating IPSEC phase1 drops openvpn

[mackkey52]

I have an OPENVPN connection to a remote site that I am using to configure a SITE-to-SITE vpn but whenever I add a Phase 1 entry and apply the changes my openvpn tunnel drops and can no longer be established. Does anyone know what the problem could be.

Trying to route the same networks over OpenVPN as IPsec or some other conflict?

Going to have to post more information.
