Auto-Reconnect IPsec VPN site to site XG105 XG85

Question

Hello, 
 I got two Sophos XG85 and one X105. 
 The two X85 devices are connecting to the X105 Sophos via IPsec Site to Site VPN. That works fine. 
 But when a devices is rebooting or loosing the power supply for some seconds it doesnt establishe the vpn connections between the two X85 Sophos. 
 On the XG105 and on both X85 the "Gateway Type" under VPN Settings is on "Initiate the connection". 
 Must I set the Gateway Type to "Respond only" on the X105 device and on the XG85 let it on "Initiate the connection"? 
 Or what must I configure to establishe a automatic reconnection for the vpn profiles if one sophos is rebooting? 
 
 Thanks so far

Hi Arvind Kumar2, 
 The policy in red, what is the Dead Peer Detection setting When peer is unreachable? Is it Re-initiate? If yes, this policy is only configurable if gateway type is configured as initiate the connection. The policy in red means you have gateway type selected Respond only. You have to change the Dead Peer detection setting on cloned policy to either Hold or Disconnect. 
 Thanks,

Hello Patrick, 
 You may set the connection as Initiate the connection on both end as both firewall would establish the connection if one is down. There is an option in the VPN policy when assigned to the IPsec connection. This option would automatically restablishes the connection if the peer is dead or not reachable.
