Need help configuring tunnel locally

[kerryhall]

I have my desktop and an RPi behind my router. I figured my RPi is a great place to test setting up my tunnel.

I have ssh'd to my RPi from my desktop, and started to run the commands for "Linux-route2".

modprobe ipv6

seems to work fine, but then my ssh session hangs on:

ip tunnel add he-ipv6 mode sit remote 216.218.226.238 local 71.37.7.116 ttl 255

and I can't ssh back in, meaning to me that I killed networking on my RPi. Any ideas? Thanks!

Since you're behind your router, you need to use the NAT address of your device.

You mean the local RFC 1918 address? ie, 192.168.0.41?

So the command should be:

ip tunnel add he-ipv6 mode sit remote 216.218.226.238 local 192.168.0.41 ttl 255

Sorry for the noob questions, just want to be absolutely clear. Thanks!

correct

Running:

ip tunnel add he-ipv6 mode sit remote 216.218.226.238 local 192.168.0.41 ttl 255

Killed my ssh session as well. That shouldn't happen even if the info is wrong though, correct? Since that is just setting up the interface?

On the router itself would be the best place to set up the tunnel. That of course requires a router, which supports it.

Killed my ssh session as well.

When you have opened the ssh connection, try to type echo $SSH_CONNECTION such that you know a bit more about the connection before you kill it.
