Hey folks, when you create a gif with IPv6 tunnel endpoints tcpdump on the underlying interface will show you some kind of error that 0 != 6 and packets will be dropped. IP6 version error: 0 != 6 repeating for each packet. happens only while sending. receiving works. This happens only on 12-current as I am aware, 11-stable works good. I worked around this issue by setting IPv4 tunnel endpoints. And this issue is not related to what you transport. You can do IPv4 or IPv6 ( proto 4 or proto 41 ) the issue remains the same. With IPv4 tunnel endpoints ( inet tunnel ) it does dualstack w/o any issues. Strange. Isn't it? -- Lars Schotte Mudroňova 13 92101 Piešťany
