I do not own my own router.

One thing which exists in a big way in Canada, is that ISP subscribers own their own router. But as it happens, my router is owned by Bell and rented to me. The official reason for this, is the fact that my router also provides me with Bell Fibe TV, which contrarily to the naming, is in fact provided over IP via DSL twisted-pair wires.

This paid-for TV content is DRM, so that it is hard to imagine that any other computer enthusiasts have managed to set up their own router, and to receive Fibe TV anyway.

But this also means that I do not have the access to flash my own router. Bell can flash the router when they see a need, but I cannot. And this also means that I cannot obtain full control over this router.

Readers might think that this is an odd situation, for a person who sets up a Web-server, and an OpenVPN-server, at his home IP address. But by using IP-tables in my Linux configuration, I have been able to do precisely that. In particular, the OpenVPN-server requires an ‘IP Masquerade’ to work. But as of my last test, it does work.

But because I am a person who ‘sometimes thinks suspiciously’, I have also had ideas, about what other consequences might arise, from the router being under the control of somebody else. One thing which may happen, is that this router, which displays no options or information regarding IPv6, may get confused and start dropping clients, over repeated requests for IPv6 addresses.

The Web-interface of this router is a dumbed-down interface, which I can access, but which for my benefit, does not give me deep control over the settings. One thing which remains true however, is that in Canada, there is next to no real use of IPv6 from the side of ISPs.

Now, I have set up an IPv6 gateway, which allows my site to be fetched by way of IPv6 if this is desired. But I have also set up my ‘ip6tables‘ in such a way that any request my Server makes for an IPv6 address, gets routed to this gateway, and not to my physical Ethernet connection. It is only logical. So ‘ping6‘ works gloriously on the Server, but not on my laptop. When I do a ‘ping6‘ on my server-box, I also get to see a graphical display in my ‘gkrellm‘ monitor widget, of activity going out over my ‘teredo‘ virtual NIC, not over my real NIC.

And so I have a somewhat lopsided configuration at home, but one which does what I want it to do.
