on 5.13.19-2-MANJARO x86_64 i am trying to find out if my IPv6 configuration is wrong or missing anything or my router or my ISP does not support IPv6.
$ ping -6 google.com -c 3 -w 3
PING google.com(prg03s05-in-x0e.1e100.net (2a00:1450:4014:80c::200e)) 56 data bytes --- google.com ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 1999ms
$ sudo ip6tables -S
-P INPUT ACCEPT -P FORWARD ACCEPT -P OUTPUT ACCEPT
$ ip a show maininterfacename
2: maininterfacename: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether aa:bb:cc:dd:ee:ff brd ff:ff:ff:ff:ff:ff permaddr aa:bb:cc:dd:ee:ff altname enp3s0f1 inet 192.168.0.2/24 brd 192.168.0.255 scope global noprefixroute eno1 valid_lft forever preferred_lft forever inet6 fe80::aaaa:bbb:ccc:ddd/64 scope link noprefixroute valid_lft forever preferred_lft forever
(so it detects some IPv6, NetworkManager is set to IPv6 Automatic method.)
$ ip -6 r
::1 dev lo proto kernel metric 256 pref medium myvpnserveripv6subnet::2 dev wg0 proto kernel metric 256 pref medium fe80::/64 dev maininterfacename proto kernel metric 100 pref medium fe80::/64 dev ifb0 proto kernel metric 256 pref medium
the wg0 VPN server through which i am sending the traffic is i believe well configured for IPv6 (AllowedIPs=sfe80::/64, myvpnserveripv6subnet::2/128) and pings to google. Is able to ping self (myvpnserveripv6subnet::1), but not VPN client myvpnserveripv6subnet::2
$ cat /proc/sys/net/ipv6/conf/all/forwarding
(on the client where IPv6 may be issue is 0)
so assuming that server is well configured, i would like to discover what are IPv6 obstacles on the client - 5.13.19-2-MANJARO x86_64. NetworkManager GUI wired configuration shows IPv6 is set to Automatic and “$ ip a show” detects some IPv6 as shown above. Please do you have an idea about command, what to look for?
UPDATE: this issue was fixed by xabbu, thanks to his help i have summarized steps to do in this comment.
