    Hi @thom_ko

    After check, it might be the behavior changed after IOS upgrade the firmware from 12 to 13.
    USG has sent packet to the client, however we do not know why the client send back USG disconnected packet. We're still checking on it.
    You can have a try to build up L2TP tunnel to the device, if it is not necessary to use IKEV2 to build a tunnel,

    Dear @Zyxel_Jerry,

    I posted about this problem in march. So far there's absolutely no feedback from your side in regards if this will ever be fixed. I also don't see any update in the knowledgebase article considering this topic. It easy to blame the other party (in this case Apple). If it would be a general issue and other VPN-gateways would have been affected as well, Apple would already have fixed it. IKEv2 is not so uncommon these days. Additionally VPN's have been used more frequently during the Covid-19 pandemic.

    In the end you're advertising and selling a feature which doesn't work. The support of IKEv2 was one of the reasons I decided to buy the USG20W-VPN. I have been a happy Zyxel customer for over 20 years. But regarding the issues I had with the USG20W-VPN (see my thread about Wifi stability which is amongst the ones with the most posts in the forum), I'm definitely not going to buy a Zyxel product again. As a client I expect a product (hard- and software) to be properly tested and verified prior to it's being released. Another point I criticise is the lack of a proper bug tracking system where we as customers could report bugs and have an insight about their status and progress.

    Best regards,
    Thomas
