  • Now IPv4 over IPv6! :)

    From Tony Langdon@3:633/410 to All on Sun Dec 8 20:18:00 2019
    Well, APANA changed their OpenVPN server, and after a few teething troubles, I've just switched to their new server. I'm still getting the same block of IPv4 addresses for my BBSs, but now my OpenVPN tunnel is on IPv6, so I am carrying IPv4 in IPv6, effectively.

    I wonder if anyone else is using IPv6 to tunnel IPv4 to their BBS. :)

    Hi Tony,

    How did you configured OpenVPN for IPv6? Can you share some info?

    Thanks.

    Best regards,
    Andrei

    Hi Tony,

    How did you configured OpenVPN for IPv6? Can you share some info?

    Here's an abridged version of my config. :)

    writepid /var/run/openvpn-vk3jed.pid
    remote 1234:dead:beef:4e00:5054:ff13:fe31:99b3 # I've used a bogus address proto udp6 # UDP tunnel over IPv6
    verb 5
    comp-lzo
    float
    dev tun0
    link-mtu 1440 #<==== link-mtu and mssfix may not be required!
    #mssfix 1000
    secret keys/vk3jed.key
    ifconfig 202.12.89.161 192.168.200.11
    port 5678
    ping 20
    ping-restart 120
    script-security 3
    up /etc/openvpn/apanasa.up


    The main things to do are to specify an endpoint that is reachable via and listening on IPv6 (domain name with AAAA record or literal IPv6 address), and to specify the protocol as udp6 or tcp6 (whatever the server is expecting). The rest of my configuration is basically the same as my old VPN over IPv4.

    Thanks.

    Let me know if you have success getting OpenVPN working over IPv6. From my experience, it should be painless. :)
