Per, past time for me to try this.
My ISP is Comcast and they are said to have good IPv6.
I have a Netgear R6900 router.
I have a Leap 42.2 test machine cat5 connected to it.
Hi Greg,
soonds good.
I just went into the router's advanced settings and told it to auto-detect IPv6 (previously disabled). It says I now have a WAN and LAN IPv6 address for the router (shockingly easily done).
Yast says I have IPv6 enabled (since install I assume).
ifconfig shows I have 2 global IPv6 addresses for eth0 (why 2?)
Could you post output from "ip addr"? Anyway, having multiple IPv6 addresses is normal and just one of those new things you will get used to. a) a link-local address, fe80:: b) a public ipv6 address.
I have 3 total. 2 global, 1 link local
sudo ifconfig root's password: Sorry, try again. root's password: eth0 Link encap:Ethernet HWaddr 30:5A:3A:54:0D:E1 inet addr:192.168.1.13 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: 2601:c0:8105:82f0:3de5:c309:46c3:20c3/64 Scope:Global inet6 addr: 2601:c0:8105:82f0:325a:3aff:fe54:de1/64 Scope:Global inet6 addr: fe80::325a:3aff:fe54:de1/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:72376332 errors:0 dropped:377508 overruns:0 frame:0 TX packets:366573445 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:7539698600 (7190.4 Mb) TX bytes:358463779849 (341857.7 Mb) Memory:fb700000-fb71ffff

What next? How do I test?
Try "ping -6 google.com".
invalid syntax, put ping6 works!
Next point your browser to http://test-ipv6.com/
9 green, 1 red The red test was large packets. It says I have an issue with MTU.
Works!
You can also have a look at the routing table "ip -6 route show".
ip -6 route show 2601:c0:8105:82f0::/64 dev eth0 proto kernel metric 256 expires 339782sec pref medium fe80::/64 dev eth0 proto kernel metric 256 pref medium default via fe80::deef:9ff:fea7:7e28 dev eth0 proto ra metric 1024 expires 1564sec hoplimit 64 pref low
So now every hacker in the world knows my info and I have no idea if I have a firewall in place!
