IPv6 is enabled by default on RHEL / CenOS 7 systems. So, if IPv6 was disabled on the system intentionally, it can be re-enabled by the following either of the methods described below. 1. Enabling IPv6 in kernel module (requires reboot) 2. Enabling IPv6 using sysctl settings (no reboot required) Enabling IPv6 in kernel module (requires reboot) 1.

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.

With the simplified IPv6 packet header the process of packet forwarding by routers has been simplified. Although IPv6 packet headers are at least twice the size of IPv4 packet headers, processing of packets that only contain the base IPv6 header by routers may, in some case, be more efficient, because less processing is required in routers due Enabling IPv4 Forwarding on a Linux machine is a rather simple task, luckily. The term IP Forwarding describes sending a network package from one network interface to another one on the same device. It should be enabled when you want your system to act as a router that transfers IP packets from one network to another.

On this page you can test the ping latency of your internet connection, and compare the performance of your IPv4 and IPv6 connectivity.

By default, IPv6 traffic forwarding is disabled, so using this command enables it. Also, as you’ve probably guessed, IPv6 isn’t enabled by default on any interfaces either, so we have to go to each interface individually and enable it. There are a few different ways to do this, but a really easy way is to just add an address to the interface.

Disable IPv6 forwarding on all interfaces: (Note: IPv6 forwarding can also be disabled on a per-interface basis by using the interfaces ipv6 disable-forwarding command) # set system ipv6 disable-forwarding Reenable IPv6 forwarding: # delete system ipv6 disable-forwarding Show the current IPv6 forwarding configuration: # show system IPv6 Online Port Scanner IPv6Scanner is a port scanner that allows you to probe a server for open, closed or filtered ports. You can specify a host name, IPv4 or IPv6 address.
