The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. In IPv4, the subnet mask 255.255.255.0 is 32 bits and consists of four 8-bit octets. Your settings mirror mine. This part has 16 hexadecimal characters. So you need to add the VIF 10 and change the /60 to /56. Subnet isolation and DHCPv6-PD: IPv6 firewall configuration in the Unifi Controller does not currently support networks that obtain their IPv6 prefix from the ISP with Prefix Delegation (DHCPv6-PD). 4. Of course a Cloud key to manage it all (so I don’t need to install Java on my PC). IPv6 Interface Type: Prefix Delegation; IPv6 Prefix Delegation Interface: WAN; IPv6 Prefix ID: VLAN ID.

( 5m 48s ) Arris Support: Yes. This is an unofficial community-led place to discuss all of Ubiquiti's products, such as the EdgeRouter, UniFi, AirFiber, etc. Most of the router/ gateway doesn't support IPv6 and we can change the IPv4 address but not IPv6.

Edit:My ISP gave me incorrect info, prefix delegation size should have been /56 so the prefix id should have been 8. So that means we can enter 0-9 for the first 10 networks and then A-F for networks 11 through 16. 3. Als telenet slechts 1 prefix aanbied, zullen er toch terug meerdere clients zijn die zonder IPv6 het internet opgaan. An IPv6 address is 128 bits in length and consists of eight,16-bit fields, with each field bounded by a colon. Tried to use the Json, but get all errors. IPv6 Interface Type gets set to Prefix Delegation, you select the WAN interface you used earlier, and you set the IPv6 Prefix ID to 1. My ISP had me use the following settings for IPv6 on my WAN interface: Now I'm trying to setup DHCPv6 on my LAN interface with Prefix Delegation so I try the following settings: My ISP refuses to help and almost nothing I find on the web is helpful except this: https://community.ubnt.com/t5/EdgeRouter/DHCPv6-What-is-prefix-id-for/td-p/1512263. My LAN IPv6 Prefix ID is empty and my IPv6 works fine. 2001:db8:3c4d:15::/64.

Hi, it seems that the Prefix-ID for IPv6 is not working in the GUI with the latest stable 5.7.20. If all you get from them is a /64, that is enough to assign an IPv6 prefix to you inside interface (GigabitEthernet0/1), but not enough to address the res of your internal network. But 2Degrees uses VLAN 10 and /56 size IPv6 address prefix delegation, not the standard /48 or /64. Ich habe versucht über mein Unifi USG und aktueller Controllersoftware (5.8.28) ein /56 IPv6 Netz zu bekommen. Hi, note: Unifi Controller and USG. This article provides guidance on provisioning a UniFi Security Gateway (USG) and internal networks with basic IPv6 functionality with UniFi version 5.4.11+ for DHCPv6 WANs with prefix delegation. Your prefix ID is 0-255, one ID for each /64 subnet. The IPv6 firewall settings require the administrator to know the network prefix, but the prefix from PD is unknown and may change over time. Prefix: Range: Number of /64s: Select a number of subnets or a subnet size to divide the above into: Calculate subnets or Calculate. Now, go to “Interfaces”, click on “LAN”. Those aren't valid. Neighboring devices are identified by their device ID. This is what I used to copy and paste: https://community.ubnt.com/t5/UniFi-Routing-Switching/5-7-20-GUI-IPv6-Network-ID-not-working/m-p/2284699/highlight/true#M81891. New comments cannot be posted and votes cannot be cast. Update (11/22/2017) for Unifi 5.7.7 or higher which added ipv6 support in the UI.

My ISP had me use the following settings for IPv6 on my WAN interface: Connection Type Using DHCPv6. En België was nu net één van de beste leerlingen als het IPv6 aankomt Ik hoop echt dat Telenet minstens enkele prefixen zal aanbieden/toelaten. Most importantly, does your isp support ipv6? Le 4to6 est le fait d'incorporer une ipv4 dans une ipv6. Each hexadecimal character represents 4 binary bits so that means that this part is the prefix: 2001:1234:5678:1234. Could you please post de output of a "show ipv6 dhcp int"to verify the prefix size you get from them. Indicates that a 6to4 routing prefix follows. Hallo ich hoffe hier kann mir jemand helfen.

Since a while I run my home network on Unify hardware. Apply the settings. Even given the most profligate IPv6 network prefix consumption models, no fewer than three additional /3s remain to allocate before IPv6 would be completely exhausted of unused network prefixes (and even that unlikely outcome ignores the availability of vast amounts of unused space inherent in existing allocations. This is an unofficial community-led place to discuss all of Ubiquiti's products, such as the EdgeRouter, UniFi, AirFiber, etc. Tried to use the Json, but get all errors. IPv6 Prefix ID 這個位置應該是寫 64，但是在 5.9.29 如果這邊填寫任何數字的話，都會有錯誤信息無法保存 Looks like you're using new Reddit on an old browser. UniFi’s router firmware (version 4.4.22.5086045) and cloud controller (version 5.8.30) configure DHCPv6 Prefix Delegation on both the WAN interface and the PPPoE interface; the outcome of which is that the router obtains an IPv6 address – but nothing else in the network does. IPv6 Connection Type: Using DHCPv6 Prefix Delegation Size: 56. Since we use a /64 it means that the first 64 bits are the prefix. The IPv6 PPPoE config on the page you pointed to looks to be very close to what you need for the usual setup of dynamic IP addresses with prefix delegation and SLAAC IPv6 addreses. Prefix ID could have been anything up to 256 (ff, as it's hex). The interface information includes the IPv6 prefix of the interface, the network mask, the type of network it is connected to, the devices connected to that network, and so on.

Inthe next figure, the x's represent hexadecimal numbers.Figure 3-2 Basic IPv6 Address FormatThe leftmost three fields (48 bits) contain the site prefix. Prefix Delegation should be pre-selected for you, and there is very little that you actually need to configure, except the Prefix ID, and whether or not to enable the Router Advertisements. I’ve chosen to use the VLAN ID to help identify in the firewall rules later. My ISP claims to support IPv6, and according tech support at my ISP my router has an IPv6 address.

Select Prefix Delegation from the options. For the “IPv6 Prefix ID”, you may enter anything from 0 to F (hexadecimal) since we have 4 bytes to allocate to our local networks (up to 16 networks). Everything, including IPv6 worked perfectly with a a single LAN zone. When the Security Gateway status changes from Provisioning to Connected, then Restart the Security Gateway by selecting Restart at the right of the screen. If your ISP is providing a /56 and you are providing a /64 to your network then you can have 256 /64s and the router doesn't know which one to assign to that interface. The rest of the IPv6 … 3- Set IPv6 Interface Type to 'Prefix Delegation' 4- Set IPv6 Prefix ID – You will most likely want to split /56 into 256 /64 subnets. fe80::/10 Make sure you’re using the right WAN interface (usually WAN1) Enter the network block size in the IPv6 Prefix ID field ( 4m 11s ) ndb217: Right, but this devices handles the prefix delegation ( 4m 32s ) ndb217: So the prefix delegation size for IPv6 is hard coded into the modem as a /64? I'm glad you got the prefix delegation from Cox to work. Note: This can only be done with a … 4. I've got 3 local networks and my prefix-ids are 0, 01 and 02.
