Hi,
I've got a very cheap originally free tier compute engine (VM).
I setup my tunnel and the remote end doesn't answer for ping:
root@ub2-1:/etc/netplan# ping 2001:470:1f1a:xxx::1
PING 2001:470:1f1a:xxx::1(2001:470:1f1a:xxx::1) 56 data bytes
From 2001:470:1f1a:xxx::2 icmp_seq=1 Destination unreachable: Address unreachable
I open up the firewall for the tunnel server IP address which the Budapest server.
I didn't get any packet from the server checking tcpdump ens4.
I read somewhere google doesn't allow tunnel protocol 41 (IPv6 encap).
Is that true?
TIA,
Ruzsi
Addendum:
he-ipv6: flags=209<UP,POINTOPOINT,RUNNING,NOARP> mtu 1480
inet6 2001:470:1f1a:xxx::2 prefixlen 64 scopeid 0x0<global>
sit txqueuelen 1000 (IPv6-in-IPv4)
RX packets 0 bytes 0 (0.0 B)
RX errors 0 dropped 0 overruns 0 frame 0
TX packets 0 bytes 0 (0.0 B)
TX errors 191 dropped 0 overruns 0 carrier 191 collisions 0
Something wrong! There are TX error and carrier and no TX packets!
Where could be the problem? In my config (VM) or Google part (filtered protocol)?
I know there is native IPv6 support many GCEs except this very small (almost hobbyist) machines.
TIA,
Ruzsi
Check your IPv6 address instructions: Make certain your "xxx" field is an odd number as that is used for the tunnel endpoints. An even "xxx" is used for the routed /64 at your site (usually on Ethernet), and thus does not belong on the point-to-point interface.
