[atlas] IPv6 Doesn't Work

No filtering here. Furthermore it seems the Atlas Probe is not able to get anywhere out via IPv6 too.
I'm wondering is the Gateway setting correct? [Gateway(s) 	fe80::1]

Hi Jiri, 

for me it looks like you're not reachable indeed:

Are you by any chance filtering ICMPv6 on your ingress router?
