ipip6 tunnel drops incoming traffic

tz flag

Tunnel defined as follows:

ip -6 addr add 2001:122::100/64 dev ens224

ip -6 tunnel add myTunnel mode ipip6 remote 2001:26::250:f1ff:fe20:da4f local 2001:122::100 dev ens224

ip link set dev myTunnel up

ip -6 addr add 4001:122::100 dev myTunnel

ip route add 192.168.0.0/24 dev myTunnel

Looking at myTunnel I see all traffic is dropped:

TX errors 11981019  dropped 11981019

Wireshark capture shows some Linux cooked header instead of ETH header.

This worked on Ubuntu 14.4, but does not on 22.04

Anybody faced such strange behavior?

Looks like ipv6-over-ipv6 tunnel you have ipv6 addresses on physical and tunnel interfaces is it you want exactly?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
