FW XG210 - IPsec site to site : protocol used

What security protocol is supported by XG 210? AH or ESP --- or both? How do I see know which one is being used?

The reason I ask it is because under "VPN"-->"IPsec Profiles" I dont see the option. My guess that ESP is the default protocol?......

Am trying to establish a VPN tunnel with a third-party and their VPN settings are as shown on below table BUT so far I have been unable to make it work....and want to eliminate the possibility of an "ESP" issue....also, how can I disable the "PFS"? I read on a different post that all I need to is to select "none" on Phase 2 on the "PFS Group (DH Group)" which I did however when I go to the main page of "IPsec Profiles" I still see it as "Enable".....

Any help is greatly appreciated.
