It appears you already figured out your issue, but I just wanted to point out that DH groups 16 thru 18 have known issues, I believe it started in v4.39.From firmware release notes:IKE v2 Proposal mix not working (DH16, DH17, DH18)

Hi @Zyxel_Can
Maybe you fixed the DH group issue, but the devices are too slow for this. When tunnels had been negotiated, the GUI was very slow and showed a lot of CLI errors, CPU worked on 90%... and that's why tunnels hadn't been established.0 -
DH19(ECP256), DH20(ECP384) is support by Azure. (DH21 is not support)
It's an alternative to DH16,17,18 with same security strength but fast.

Hi @gb5102,
Thank you for your comment.
All of the firmwares after v4.62 covers IKE v2 Proposal mix not working (DH16, DH17, DH18) fix.Are you saying the known issues with DH16/17/18 are fixed in current firmware versions?Because this issue is still listed under "Known Issues" section in v4.65 release notes for Zywall 110.

Hi @gb5102,
Sorry for misunderstanding.
The fix was actually implemented in the forum release version.
Currently the latest forum release version is 4.62 WK14:
