01.01.2022 · ISP only assigns a /64 prefix for me, there is PD available, so with the modem bridged my lan clients behind openwrt router can obtain v6 addresses. I have some docker containers running on a small Linux box, my intention: Separate these containers from my LAN network with vlan and setup separate firewall zones for security reason, while obtaining ipv6 …

Nov 26, 2018 · * OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.228.31946-f64b152) - Steps to reproduce 1. IPv6 enabled by default, OpenWRT automatically generates a unique ULA prefix per RFC4193. 2. ULA prefix is announced with Infinite Preferred and Valid Lifetimes, rather than the RFC4861 defaults:

[Solved] Auto-generate ULA Prefix on compiled firmware ... I firstly installed a firmware I've downloaded from OpenWRT site, ...

Nov 27, 2021 · The default class for a prefix is the interface-name (e.g. “wan6”) or “local” for the ULA-prefix. This can be used to select upstream interfaces from which subprefixes are assigned. For prefixes received from dynamic-configuration methods like DHCPv6 it is possible that the prefix-class is not equal to the source-interface but e.g ...

Box here in Germany, OpenWrt gets a global IPv6 address (calculated from SLAAC global prefix, optionally from a ULA prefix, and optionally ...

04.01.2017 · You don't need to configure an ULA prefix, but I would nevertheless recommend setting one. It's basically simple, if your (IPv6) uplink (wan6) ever goes down, your globaly IPv6 addresses go down as well, thereby crippling LAN internal connections as well (this is exaggerated, but to get the concept, you won't even be able to connect to your own router (via …

18.01.2017 · OpenWRT creates, by default, a ULA prefix – a deprecated “site-local” prefix. While these are perfectly valid, I’ve found that non-globally routable IPv6 addresses tends to confuse the heck out of Android-based phones, resulting in certain operations taking forever while various network operations time out, and are then retried with globally routable addresses.

Aug 10, 2018 · The setting "IPv6 ULA-Prefix" in the LuCI Interfaces screen represents a subnet of local addresses that are used for private networking in the same manner as "192.168.x.x" is in IPv4. To be compliant with the protocol, the prefix must be set to a subnet within "fc00::/7" aka "fc__:" and "fd__:", though the standard recommends that you use "fd ...

The IPv6 ULA-Prefix is generated for you. To change or refer to it, go to: Network >> Interfaces >> Global network options. FYI: the ULA-Prefix here is the common network portion of the address (first 4 quartets), and the IPv6-Suffix (last 4 quartets) is the unique self-generated host portion.

My ISP supports DHCPv6-PD and I would like to assign IPv6 addresses to my subnet with both the global prefix and the ULA prefix, ...

I'm sort of thinking out loud here but my idea would be to have odhcpd assign addresses out of the ULA prefix to both local router ...

Nov 27, 2021 · The default ULA (Unique local address) prefix represents an address that is not globally routed on the internet by design. A lot of clients will prefer IPv4 over a ULA IPv6 address if there is no global IPv6 address assigned, so you may need to change your existing ULA prefix to indicate a global address to ensure traffic goes over IPv6 by default when possible.
