Hi guys,
I'm sorry to bother you, but i am facing some difficulties getting my IPV6 working here in Italy. In Italy the only ISP who provides a kind of ipv6 is FASTWEB. FASTWEB does not provide native ipv6, but offers a 6rd tunnel (IPV6 6RD prefix
2001:b07:d448:f3b6::/64). The problem here is that, even after getting an IPV6 address, i cant reach or ping any ipv6 site. Here are my details:

My bet would be that having a FE80 gateway does not allow me to reach the outside world. So i tried setting a manual ipv6 and putting the above mentioned ipv6 prefix (2001:b07:d448:f3b6::/64) as my gateway, but still no luck:

I deactivated all MS ipv6 privacy settings, but nothing changed. Could you please help me?

Thanks a lot,

The  FE80 address is expected; it should be the local address of your gateway.  How are you handing out addresses? SLACC? DHCPv6?

[ilpappa]

DHCPv6 with mac addresses filtered. Tried also with no mac address filtering.

[cholzhauer]

Are you able to ping the gateway?  Can you get on the gateway and try to ping external?

[ilpappa]

I couldn't ping the gateway:

But if I remove the % sign the ping works:

I am not able to reach the gateway. I really don't know what to do. I just found a workaround creating a tunnel, but I think that is not the right way to fix the situation as my Ipv6 has to work normally. Here is what i did to fix the problem:

1) covert IPv4 (public) to IPv6 from https://www.ipaddressguide.com/ipv4-to-ipv6
2) create tunnel address starting from 2001:b07 (ISP prefix) and adding the previous conversion with ::1 at the end
3) cmd with admin rights
4) following commandsi:
   netsh
   interface
   ipv6
   add v6v4tunnel interface= private localaddress= 192.168.1.115 remoteaddress= 81.208.50.214
   add address interface= private address= 2001:b07......::1
   add route ::/0 private

I really think that this tunnel is a big resource consuming one.

Any other idea?

Thanks a lot,
Michele

[cholzhauer]

You need the % because that identifies the interface. 

Why are you converting the IPv4 to IPv6? 

If you're not able to reach the gateway, I think you've found your issue

[ilpappa]

How can i fix that and reach the gateway? Thanks

[cholzhauer]

What addresses ranges do you have?

[ilpappa]

external static ip: 93.42.79.X
internal lan 192.168.1.100-149 but they are outside dhcp range and assigned by mac address; dhcp range is 200-249

[cholzhauer]

Is this an IPv4 forum or IPv6 forum?
