I am new to the concept of network namespaces in Linux.
When I tried to follow the tutorial on this in the wiki, but my router doesn't accept netns namespaces, something's wrong and the command doesn't work as expected.
So I decided that there were maybe two other options:
I could set it up on the router without the network namespaces (netns)
I could run it on a separate machine or different router without the network namespaces (netns) where I could port the packets over.
Would either of these options be alright from a security standpoint? Would one of them be better?
I meant my option 1 and option 2, above, not the one in the tutorial. When I followed the tutorial I attempted to use option 2 and it ended up with this problem. I figure if I put the IPv6 to IPv4 gateway on another machine it won't be a problem.
