Hello Tobias, thank you for your kind reply.
Undoubtedly the message reported by microsoft about the introduction of regression is rather unclear.

There is currently no option to generally disable Vendor IDs as some are basically integral part of IKEv1 e.g. to use XAuth or DPDs, and especially to negotiate NAT-Traversal (only the strongSwan and Cisco Unity vendor IDs can be disabled with individual settings, both are disabled by default). Better use IKEv2 anyway. Regards, Tobias
