VPN & IPv6 on AX50. IPv4 under CGNAT
Im trying to set up the VPN server (openVPN) option on my AX50.
I followed these tutorial here:
https://www.tp-link.com/us/user-guides/archer-ax50_v1/chapter-11-vpn-server#ug-sub-title-1
I activated Dynamic DNS Service and binded it with my TP Link cloud account. I changed the default REMOTE [xxx.xxx.xxx.xxx IPv4 IP] 1194 on the 12th line of the generated VPN configuration file with a text editor in order to try to point out the connection to my previously configured TP-Link DDNS address (on the format XXXX.tplinkdns.com).
But I am having no luck, I can not stablish the connection through the openvpn android/windows client.
Initially I suspected it was related to my ISP IPv4 Ip being under CGNAT, but I confirmed IPv6 is properly configured on the router and it is assigning IPv6s ips to all devices on my network. So I came up to the conclussion that VPN Server function on the AX50 only works with IPv4.
Can anyone confirm these? Have anyone using these AX50 router been able to set up VPN?
I also found these link: https://community.tp-link.com/en/home/forum/topic/193732
Is that the same case with the AX50 (simply no IPv6 support VPN connectivity)?
Thanks in advance.
