How to Check IPV6 Traffic Routing

Overview

How to check IPV6 traffic routing.

Steps

1. Check to make sure IPv6 is enabled on firewall. (How to Enable and Disable IPv6 Firewalling)
   
   
2. Check the setup for the IPv6 default route. (How to Set Default Route for IPv6 Traffic)
   
   
3. Test connection from PC to the firewall Internal interface.
   For example, open a Windows system command prompt and type the following command:
   c:\> ping -6 2001:4860:0:2001::68
   
   To ping IPv6 using DNS host name:
   c:\> ping -6 {host.name}
   c:\> ping -6 ipv6.google.com
   
   
4. Ping from firewall external interface to Internet address
   > ping inet6 yes source <sourceIPV6> host <destination IPV6>
   
   
5. Ping from firewall Internal interface to Internet address
   > ping inet6 yes source <sourceIPV6> host <destination IPV6>
   
6. If there is still an issue with connecting from PC to Internet, then check intermediate devices. IPv6 must be enabled on all intermediate devices to allow traffic pass through the firewall.
