IPv6 network, subnet and device settings

English Network/Internet
#1

Using Yast one can specify an ipv4 static local address and have the router address it using forwarding. However, yast2 does not seem to have any aid of making a static global ipv6 network address, subnet and finally the device address. The only static global addresses generated are based on the network address plus MAC address, following the same principles as applied for the local link address.

In my current IPv4 setting I use two routers/firewalls. The outer one takes care of forwarding only specific traffic to a server and the inner one blocks all originating traffic to the inside.
With IPv6 I must have a subnet allocated for the server and an other subnet to allow local lan traffic reach the first subnet as well as the Internet itself. Of course, one could argue that using one (default) subnet for all, and use the inner FW to block all outside originating traffic to the other devices, is a possible way too.

Now I can’t experiment with OpensSuse 13.2 (42.1 still seems what immature) because yast2 does not seem to have support for setting up things as easy as with IPv4.

Suggestions anyone?

What you want to do should probably be done on one of your routers (the “inner” router). Because that’s the way that IPv6 addressing is supposed to work. So you would need a router capable of handling that.

Hm, this does not seem to resolve the question of making two subnets, one for the DMZ and one for the local network.
Also, how can I make a static IPv6 global address on my server and avoid any dependency on a network card (the MAC address).

If you are using wicked, just set it in YaST. Dialog says “IPv4” but it accepts IPv6 addresses, I just tested it on Leap. I do not have 13.2 to check.
