IPsec phase 1 SA deleted

[seanbnd]

Trying to setup an IPSec tunnel between a Fortinet 60e fw 6.0.5 and a Zywall 110. Everything in the tunnel settings match but I'm getting an error when they are connecting. From the Fortinet VPN event logs I see "IPsec phase 1 SA deleted. Remote port 4500 Log ID 37134. Everything up to the points in the logs show negotiate success. Using IKE2.

I was able to find the issue after stepping away for awhile and coming back. The remote WAN IP was wrong on the Fortinet. It was a correct IP, just not the same IP the remote location was using. It was using a secondary WAN IP.
