[tlug] Port forwarding/UPnP in Japan

[Christian Horn <chorn@example.com>]

Hoi tlug,

anybody having done port forwarding,
configured directly on their router or via UPnP,
to make a service from their LAN available to the outside?

I'm using a NTT PR-500KI router,
it's not offering port forwarding directly.
UPnP appears in the menus, but the specific UPnP service
to do port forwarding seems not available.

Seems like services offered on IPv6 devices on the LAN get
routed through directly.  

Might still be that the provider is doing multiple layers
of NAT in front if the IPv4 IP which the router gets assigned,
making for example a TCP service then available to the internet
would not work.
The IP the router gets is not from a private range though, so
does not directly look like they do another level of NAT.

cheers,
Christian
