Hi,
I want to implement the following:
Internet (IPv4/6) --> Opnsense/Openvpn --> IPv6 ONLY --> internal IPv6 only network
Does anyone know, if this is possible? I just set up a Openvpn server and did not define any IPv4 adresses there, now I am getting
2022-06-30 15:48:25 TCP/UDP: Preserving recently used remote address: [AF_INET]xxx.xxx.xxx.xxx:1194
2022-06-30 15:48:25 UDP link local (bound): [AF_INET][undef]:0
2022-06-30 15:48:25 UDP link remote: [AF_INET]xxx.xxx.xxx.xxx:1194

2022-06-30 15:48:25 sitnl_send: rtnl: generic error (-13): Permission denied
when trying to connect using openvpn client on linux with the ovpn file I downloaded from opnsense.
Any hint would be great!
If any more information would be useful, please let me know. I am not sure what to provide here....
Best regards and thanks in advance,
Otto
No one? :-(
What is your setting for IPv6 tunnel adress? I am wondering about "fd03" which should be "fd00".
Hi,
just found the problem :-)
It was NOT related to opnsense/openvpn - I had disabled IPv6 on the client I used to test (tough IPv6 adresses showed up with ip a).
Just tried again and VPN connection using IPv6 ONLY is working now.
Thanks anyway for your help!
Best regards and thanks again,
Otto
