IPv6 configuration help

[JOrdan01070]

Hi I need a little help getting IPV6 working, we have just had a paxton intercom installed and it only works with IPv6. The intercom does not need to access the internet we just need the configuration software to see the intercom on the network.

 

I have setup a new DHCP v6 scope and I have also created a reverse IPV6 DNS lookup zone but I cannot get anything to pickup an IPv6 address and now I am stuck and I am hoping it is something very simple but I don't have the experience to sort and I'm hoping somebody a lot smarter than me can help.

 

Our network made up of unifi switches not sure if that helps. I have not amended anything in the Unifi dashboard.

 

Any advice or help will be greatly apricated.

I suspect you'll need to do some work on your core switch. The Router Advertisment needs to be changed to indicate that hosts can be DHCPv6, in our case with Aruba it's 'ipv6 nd ra managed-config-flag' on a per vlan basis. You'll then need a helpder address configured pointing to your DHCP server.

Hi @chris11256 cheers for the pointer, there is a IPv6 setting in the unifi dashboard but I have not been able to try and configure it as it will re-provision the switch's and we lose connectivity for 1 or 2 minutes so this is something I need to look at in the holiday.

Interestingly they'll work a lot of the time without even needing an ipv6 dhcp server, they'll just use auto configuration IPv6 addresses

 

Give 2 computers IPv6 addresses and then try ping -6 between them
