Have you tried allowing incomming ICMPv6 in the firewall settings?

No changes made in the "Advanced" tab.

Why are you using DHCPv6? (SLAAC is surely used more commonly)

Thanks. I can't see why that would make a difference as the ICPM reply would be solicited, so the firewall would have it kept-state... but anyway, I tried it to be sure and it didn't make any difference

I was using the DHCPv6 server because that's what the 2860 defaulted to. Hard to find a complete idiot's guide to IPv6 so I grope around in the dark. I've turned it off now but not sure what difference this makes?

I can ping IPv6 sites from the router but I cannot ping them from any Windows 10 PC on the network. Previous Windows versions (Vista and XP) are able to.

Probably doesn't make any difference to you... but SLAAC seems to be 'preferred'. For servers and devices you
need to address, you may want to use DHCP with bound allocations to give easier to remember/access addresses.

e.g. 2A00:000:dba:5E16::1 is nicer than 2A00:000:dba:5E16:5335:d8a:68f4:5bbc
