Yes. And connect to TCP services (e.g. Telnet, etc.)

I've never used the ISP's router's port blocking/forwarding/NAT/gateway
features before (for IPv4), so now I'm looking what it supports. It does have
DHCPv6 and DHCP-PD was disabled, so I've enabled that and expecting for it to
hand out addresses in the range:

2600:6c88:8c40:5b::1 to ::1000 (according to its default configuration)

I haven't seen that happen yet. I'm guessing this means I have been allocated
a /64 (?).

Looks like I have control:

There are also options for Port Forwarding, Firewall, IPv6 Pin-holing, IPv6
DMZ, but I've never used any of those (or similar) features for my public IPv4
interfaces (my servers' public IPv4 network interfaces are just "wide open" as
far as the ISP router is concerned).

Thanks. I'll keep playing with it.
