<![CDATA[NPt Why can I not open ports?]]>I am using NPt with private IP-space and a tunnel from HE with SMTP permitted. If I open a port to my email server, it is unreachable. What am I missing?

Outbound it is working fine.

So to get this working better it would need a dialog like for port forwarding where the router can be instructed what to do for what port.

So sadly it is only working for one of my LAN interfaces, here it is :181::

I thought I had read that you can do "everything" with just one /64 but that isn't the case for me.

Why are you using NPT, if you have he.net? You have a gazillion addresses to use for the server. Of course, you can still use private addresses, in addition to the global addresses.

Now I want to use it again, but it is not working, most probably related to NPt!

I've been using the IPv6 from tunnel.he.net myself for years.
I was using a "port 22 TCP" firewall rule on the HENETv6 interface (not the classic IPv4 only WAN interface) so my dedicated servers could rsync to my NASn, living on one of my LAN's, using IPv6.

I used the IPv6 rsync as a silly reason the mystify this TCP SSH access. My firewall rule was of course 'source' (IPv6s of dedicated servers) limited.

Hosting a port 25 (IPv6) service @home : I'm to old for that ;) That's why I have these dedicated servers (OVH).

Try if you can open a port '22' over IPv6 to one of your devices, as I know that works.
