Hello,
Hi,
I am using 2 Raspberry Pis and trying to establish tunnels: 2 for IPv4 and 2 for IPv6. I used separate ones, so in sum 4 tunnels.
I'm not sure why you're using two tunnels, but I seriously doubt that's causing any problems for you.
I have done the following changes/calls:
I've quickly skimmed your commands and don't see anything that stands out as obviously wrong.
$ sudo ping -6 -I mytunnel1ipv6 2001:4860:4860::8888 ping: connect: Network is unreachable $ sudo ping -6 -I mytunnel2ipv6 2001:4860:4860::8888 ping: connect: Network is unreachable $
I think "Network is unreachable" means that the kernel doesn't think it has a viable route to the network.
I can also ping the "outer" (real) addresses:
Can you ping the inner IP address on the far side of the IP-IP tunnel?If you can't ping the IP that you're trying to use as a gateway to get to the 2001::/4 network, the kernel would think that it doesn't have a functioning route.
I know the 2001::/4 in "route add" is not useable for all Internet IPv6 addresses, but at least for these test pings that shall be enough?
Agreed.
Someone an idea, what could be wrong/missing?
Start with basics, can you ping the far inside IP of the tunnel(s).
Many thanks!
