Assume you can ping your ip6 addresses from the inside of your network?

Your router is probably blocking IPv6 traffic (most I've seen do), and you'll probably need to enable ICMP and relevant traffic to hosts if you want to enable inbound ipv6.

First thing would be to figure out if you have a static subnet, and what it is. Most folks that I've spoken with get a /60 or /56 from their ISP. Business customers may get a /48. From your prefix (2600:6c88:8c40:5b::), its not easy to figure out what addresses you got - and it my be a /64 (which would be unusual). And if you got a /60 or /56, its strange that your router is handing out ...:5b::.

I dont know Sagemcom so dont know if it is a business router (which probably gives you some control over handing out addresses), or consumer router (which would mean its probably useless for ip6).

Most OSes switch ip6 addresses regularly (hence the "temporary ones"), so dont be surprised if the ip6 address chanes often - you can turn it off to have a consistent one, or assign a static address.
