    Try using strongSwan app it has great logs. IF you get no proposal chosen i suggest to check that encryption, authentication and Diffie Hellman Groups are the same between the zywall and the endpoint.

    As for DH Groups consider that while on legacy USG serie you can choose only one group on the ATP and USG flex series you can put many, in this case you just need that at least one group is the same on both firewall and client.

    As for PFS (perfect forward secrecy) you can consider to disable it to help performance. As usual be adviced that performance/easiness and security will never be on the same side.
