Does anyone know how to run an #IPv6 #464XLAT #CLAT client inside a #Proxmox LXC container? clatd ( github.com/toreanderson/clatd ) doesn't work because tayga is unable to create a tun interface inside the LXC and I have some software to run that, you guessed it, is still stuck on the obsolete protocol + I don't want to create a full VM just for it.

First run done. All worked as expected including UEFI netboot. This is going to need some unofficial documentation done as it is lacking on the project site. Then others can automate. #OpenBSD

Getting this to work on an #IPv6 only network is going to need some work as rad.conf doesn't support dhcpd.conf options and it will be something that needs to be pulled in from ports (DHCPv6).

So for the #IPv6 #MTU issues we seemed to stumble over at @ffhl, with our asymmetric #BGP routes to/from @FreifunkHamburg / @freifunkMUC I now wrote a small bash script to test a list of websites with varying, asymmetric MTUs: github.com/T-X/ipv6-path-mtu-d. There is a suspicious amount of #Microsoft websites for the failed tests at the bottom.
Next steps would be to add analyzing of #tcpdump captures. But in a few samples it seemed like those sites did not receive / react to our #ICMPv6 Packet Too Big

Startup and first lines of running "sudo ./ipv6-pmtu-disco-verifier.sh -j16", shows a few settings, like 16 parallel jobs. The left most column is showing the URL, followed by green checkmarks underneath columns for various MTU sizes.
The next output page, still showing just green checkmarks.
The final output page, this time some red crosses are shown for apnic.net, xbox.com, microsoft.com, code.visualstudio.com, apps.microsoft.com, js.monitor.azure.com, launcher.mojang.com to the MincraftInstaller.exe download link, t.me and linked.in

Kære #fediverse jeg har brug for jeres hjælp! Kviknet/Ewii har desværre svigtet mig, min fiberforbindelse mangler IPv6, det har jeg nu manglet i mere end en uge! Hvilke udbydere garanterer IPv6 på en trådet/trådløs forbindelse på det sydlige Sjælland? Jeg har været glad for Kviknet, for deres kyndige teknikere, og for deres service. Jovist har der været bump på vejen, men det har jeg i det store billede kunne acceptere. Desværre har salget af Kviknet til Ewii, efterladt os private, der insisterer på også at have IPv6, i en dårligere situation. Er det kun med en professionel forbindelse, man i dagens Danmark kan sikre sig at have IPv6 i sin hustand? Jeg ved det er ferie-tid, men man må da kunne forvente at en ISP som minimum holder én opdateret om progress på den support-sag jeg har med dem? Halvdelen af den service jeg betaler dem i dyre domme for, virker ikke! Så kære #fedivers, hvor skal man gå hen for at være sikker på at få stabil #IPv6 ?

Some back-of-the-napkin math for those worried that we might still exhaust #IPv6 if we're not careful:

We are currently numbering out of 2000:/3, but effectively it's been 2000::/4 so far. The smallest amount of space that can be announced in BGP is a /48.

4 bits off the top and 16 bits off the bottom leaves us with 2^28 individual /48 networks we _could_ issue (obviously we're issuing larger chunks where possible, eg: /32 for many ISPs). This is representable without having to go to engineering notation: 268,435,456.

Last night's bgp.tools dump shows 117,731 active ASNs. We could issue every org with an ASN a starter /48 and still have several orders of magnitude worth of room for growth. And that's even before we get to 3000::/4.

So, don't worry about filling up the pool. Grab what you need (and maybe a bit more) and build the network you've been dreaming of.

I bought a eSIM from Bouygues Telecom for travelers.

The default setting on Android for roaming (IPv4) was wrong. But after changing it to #IPv6 it works. Firewall settings seem a little bit strange (no ping, other ICMP packets are also blocked).

464xlat (clat) works.

My first SIM with 464xlat during roaming.

#ipv6only

¯\_(ツ)_/¯

Ratestunde!

Wie / in welchem Format muss die #IPv6 localhost Adresse in die #gitlab config, damit sie passend ins yaml gerendert werden kann und danach auch von da passend in die weiteren configs gerendert werden kann?

(ganz konkret gehts um den config eintrag `nginx['real_ip_trusted_addresses']`)

Hint: `::1` ist's nicht.
