        Description

        I'm actually on the 12-BETA1

        Openvpn vpn service cannot determine if he need to listen UDP4 or UDP6

        Because on config we say only UDP, and i'm unlucky because he choose IPV6  automaticaly

        Wed Jul 29 20:15:12 2020 Diffie-Hellman initialized with 2048 bit key
        Wed Jul 29 20:15:12 2020 Failed to extract curve from certificate (UNDEF), using secp384r1 instead.

        Wed Jul 29 20:15:12 2020 UDPv6 link local (bound): [AF_INET6][undef]:1194
        Wed Jul 29 20:15:12 2020 UDPv6 link remote: [AF_UNSPEC]

         

        I think it's because i got IPV6 and IPV4 on my nas

        nas# ifconfig
        vmx0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> metric 0 mtu 1500
                options=a400b9<RXCSUM,VLAN_MTU,VLAN_HWTAGGING,JUMBO_MTU,VLAN_HWCSUM,VLAN_HWTSO,RXCSUM_IPV6>
                ether 00:0c:29:9e:03:fa
                inet6 fe80::20c:29ff:fe9e:3fa%vmx0 prefixlen 64 scopeid 0x1
                inet 10.10.0.245 netmask 0xffffff00 broadcast 10.10.0.255

                status: active
                nd6 options=23<PERFORMNUD,ACCEPT_RTADV,AUTO_LINKLOCAL>
        
        

         

        workaround set proto to UDP4 TCP4 UDP6 TCP6
