NAT / QoS → Port Forwarding doesn't allow me to enter IPv6 addresses. How do I forward IPv6 packets to a destination LAN IP Address?

i guess you have to use iptables commands..
does your local/router LAN has ipv4 addresses ?

In addition to @Alozoros, IPv6 is a global address thus needs no NAT (although it is not impossible)

Portforwarding exists of two things: address translation, which is not necessary for IPv6, and opening up a port in the firewall.
This last thing has to be done to give access (providing you have an IPv6 firewall running on the router and I do not use it myself so actually I do not know if there is an IPv6 Firewall in place but I should think so Smile

)

That's what I thought, but I wonder why I'm not getting any incoming IPv6 traffic to my site anymore. I didn't change any server settings. Is there a way I can test this?

Also, my old Asus router software had a separate page for IPv6 port forwarding. Why doesn't DD-WRT?

Then what's blocking incoming IPv6 packets?

Which one?

The LAN DHCP assigns IPv4 and IPv6.

I think there is an IPv6 firewall. Something's blocking incoming IPv6 ports.
How do I open them?

Adding this to the Firewall section of 192.168.1.1/Diagnostics.asp worked:

Code:

ip6tables -I FORWARD -p tcp -d <destination_IPv6_address> --dport 443 -j ACCEPT

(Replace <destination_IPv6_address>.)

Someone should add this solution to the wiki page.

How do I edit the wiki? When I try to log in, it doesn't recognize the same credentials I use to login to this forum.

Because the accounts and resources are not conjoined other than possibly existing on the same server. It's been added. Wasn't high on my priority list.
