IPSec XG Initiate Site-to-Site with UTM

Question

Hi, 
 is it possible to configure a site-to-Site IPSec-Tunnel between an. 
 
 XG 17.5.10 as Initiator with Public IP 
 
 and a UTM 9.5 with Public IP in only Answering mode. 
 
 If yes please share, IPSec Policys. 
 
 Problem is, on the XG Site we have 2 WAN Uplinks and we want to use Failover Groups(i thought we can only use these as initiator). 
 The Failover group in the UTM won't work correctly and I'm unable to access the UTM because it's a subcompany. 
 
 Regards

XG should be able to be a Respond Only Failover Group. 
 It will try to terminate the session and listen to the other Interface, in case WAN1 is down. 
 Try to configure both tunnels with the same configuration. 
 Verify, the Tunnel is up with one Tunnel only active. If so, configure the second interface with the same configuration. 
 
 Use the SG Mechanism to configure the IPsec Failover on UTM site.
