[opensuse] setting static route in yast looses internet connection
why when I set a machine a static ipv4 route using yast do I loose network outside my local net, outside my router. I still have connection locally, machines connect to my router. I know I am missing a step. Do I need to change something in the router configuration? I have no problem if I let dhcp set the local addr tks, -- (paka)Patrick Shanahan Plainfield, Indiana, USA @ptilopteri http://en.opensuse.org openSUSE Community Member facebook/ptilopteri Registered Linux User #207535 @ http://linuxcounter.net Photos: http://wahoo.no-ip.org/piwigo paka @ IRCnet freenode -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Generally, you don't have to set an IPv6 address. The router advertisements are used by the computer to determine the prefix and router address. 64 bits, based on the MAC and/or random number are used to create the 128 bit address. However, I haven't tried connecting with a computer that has a static address. So, just enable DHCP to test to see what happens. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Oh. Curious! How does it do that, what component listens for it? If one sets a static IPv4 address in yast it also expects one to write an IPv6 address there. I don't expect a dhcp6 client to be listening unless specified.

Where's that fc00: coming from? That's one of the Unique Local Address ranges.

Well, they did a test with a few customers. I only know they did it, not what was the results. I found some threads on the official support site, dated a year ago, and they (the ISP) says there is nothing. Comments say that our routers do get an IPv6/128 address, but unusable, there is no prefix (don't ask me what that means). Seems they use 2A02:9100: Some Spanish links, just to record them somewhere: http://comunidad.movistar.es/t5/Soporte-T%C3%A9cnico-de-Fibra-%C3%93ptica/Co... http://comunidad.movistar.es/t5/Soporte-T%C3%A9cnico-de-Fibra-%C3%93ptica/So... https://www.telefonica.com/es/web/public-policy/blog/articulo/-/blogs/descub...

That is a valid address blocks. Currently only 1/8th the IPv6 address space is allocated to global unicast addresses, so all valid ones start with 2 or 3 and I've never seen one start with 3. BTW, over 3/4s of the address space has yet to be allocated to anything. However, you can get a /48 prefix from Hurricane Electric for free, but you'll have to set up a 6in4 tunnel. A prefix is like an IPv4 subnet mask, in that it determines how many bits are yours. So, if you have a /48 prefix, you have 128-48=80 bits to yourself, for 2^80 addresses or 65536 /64s. LANs normally have a /64 prefix. My ISP gives me a /56 for 256 /64s.
I don't read Spanish, but my ISP also provides IPv6 to their cell network. My phone has an IPv6 address and all IPv4 traffic uses 464XLAT to send it over IPv6. With some phone models, even tethered devices get an IPv6 address. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I don't quite follow this. I suppose that if I browse the web via this tunnel, the replies will automatically go back via the same tunnel, no problem there. The problem would be if some one tries to contact me on IPv6: Hurricane (or other) has to open a connection to my IPv4 address via the tunnel. I don't see the problem there, as long as the tunnel is connected at both ends. Or is it something else? :-? -- Cheers / Saludos, Carlos E. R. (from 42.2 x86_64 "Malachite" at Telcontar)

I think he was referring to the fact that some people are behind carrier grade NAT, which means they don't have any public IPv4 address and so have nothing for the tunnel to connect to. 6in4 use IP protocol 41 and you have to provide a valid IPv4 address for those packets to be sent to.

You don't it should happen automagically. An IPv6 router uses router advertisements to inform devices of it's address and the network prefix. To see if this has happened, use the ifconfig command.
