IPv6 address as IKEv2 VPN server address on iPhone native VPN does not work

We would like to specify IPv6 address as VPN server address on native VPN of iPhone.

We dont see any packets coming out of the phone to the VPN server. However, on MAC it works.


Any help or guidance on this. Does iOS support IPv6 address for VPN server for IKEv2 native VPN?

Thank you for your inputs and clarifications.. I understand mistake I was doing.. iPhone seems to have got 2 IPv6 IPs and IP used for VPN is different from the one used for browsing. I had firewall open for one used for browsing..


Kindly close this thread.

Thank you for your response. I see the link says IPv6 supported for VPN server. We are expecting the same.. But, when we specify an IPv6 address for VPN server, we dont see any IKEv2 packets coming out from the device to establish VPN session.


If we specify IPv4 address, it is fine, we see IKEv2 packets to setup session. We want to know whether IPv6 addressing to VPN server is indeed supported as mentioned in the link.
