Jan 25, 2019 · Configuring IPv6 and IPv4, forward and reverse DNS. We can configure IPv4 and IPv6, forward and reverse split DNS with bind so that same server can handle both IPv4 and IPv6 clients and at the same time give different responses based on whether query is coming from intranet IP, localhost or from global Internet, etc.

The [-4|-6] is optional and lets you specify whether you'll bind (listen) on IPv4 or IPv6 (respectively). -l is also optional. It lets you choose on which address (IPv4 or IPv6) you want to bind. The original port is the port on which you'll bind. The …

To learn more about IPv6 read the new ETSI White Paper on our website “IPv6 Best Practices, Benefits, Transition Challenges and the Way Forward”, or listen to the recorded ETSI webinar.

25.01.2019 · Configuring IPv6 and IPv4, forward and reverse DNS We can configure IPv4 and IPv6, forward and reverse split DNS with bind so that same server can handle both IPv4 and IPv6 clients and at the same time give different responses based on whether query is coming from intranet IP, localhost or from global Internet, etc.

For example, if you want to allow an IPv4-only server, listening on port 1337, to be accessed over IPv6, use: 6tunnel -6 1337 localhost 1337. The above command will listen on port 1337 on IPv6, and forward the traffic to port 1337 on the same machine via IPv4. It will then run in the background, so you don't have to worry about it.

Good question. While the answers seems trivial, it actually isn't. First off, I would like to say that most home routers are actually router+firewall.

Check open port or your public/external IP V6 and remotely test if a port is open or closed. It is useful to users who wish to check open port online or verify port forwarding and check to see if a service is running or a firewall or router forwarding port or ISP is blocking certain ports.

Mar 02, 2017 · conf/all/forwarding - BOOLEAN Enable global IPv6 forwarding between all interfaces.

Feb 07, 2018 · With IPv6 port forwarding, this could be done for IPv6 using site-local addresses for the destinations (DHCPv6 or static). Otherwise I'd need to configure the DHCPv6 server to assign correct world-routable addresses with static mappings to each host.

I understand the concept of forwarding. What I was asking is, basically, even though I have a /64 prefix on my IPv6 link, I cannot just take any other address on that prefix and use it (for whatever purpose, be it containers or running my own private IPv6 tunnel broker)? Finally, Linode has an option to request another IPv6 prefix.

This guide provides details on setting up IPv6 routing on a Gentoo ... First add entries for both forward and reverse DNS zone files in ...

22.06.2021 · To forward IPv6 traffic on an interface, you must configure a global IPv6 address on that interface. Configuring an IPv6 address on an interface automatically configures a link-local address and activates IPv6 for the interface. The configured interface automatically joins these required multicast groups for that link:

You can't do that with NAT and IPv4 port forwarding. So find your routers IPv6 firewall section, and just permit the ports you want available to ...
