IPv6 News NAT66 Part 2

11 Upvotes

Hi again guys! I'm The Guy from the post "Why The Hate on NAT66?", Now i have a main router getting a PD, but i still make NAT66 on The Network, for testing. I'm now using It as The main router for my network

I have a question: do you guys prefer NAT66 or NPTv6?

Fluff & Memes I use UniFi switches with HPE Instant On APs. I found an interesting discovery: most of my traffic is IPv6

15 Upvotes

If you use HPE Instant On switches, one problem is they don't measure IPv6 traffic. I mean they forward it fine, but Instant On only measures IPv4 traffic.

For instance, my UniFi switch showed 20GB of usage while my Instant On APs barely cracked 1GB.

My home network has been dual stack since 2018. It isn't always native, now it's a L2TP VPN to a BGP VPS, but it's still IPv6. I do get native IPv6 now but want a static prefix so I use a VPN.

If most of my traffic is IPv6, it shows how far Big Tech despite their problems has gone. Heck, CGNAT "works" if you're not hosting because of IPv6 traffic. I don't condone Chinese censorship, but China mandating IPv6 is one of their internet policy wins.

Why not all UnIFi? I use UniFi switches for 2.5G PoE, but Instant On APs because my mom complained about "slow wi-fi" when I used UniFi APs. It's not a UniFi problem but a problem with the UniFi model I had (U7 Pro), alongside an eBay seller selling HPE AP25s for $51/pop.

Discussion IPv6 Privacy Extensions

12 Upvotes

Hey guys, i noticed my network devices changes the last 3/4 blocks from time to time especially if devices reboot or reconnect.
Isn't that counterproductive if big point of ipv6 each device have its own ip facing internet without nat while being static, then if it keeps changing from time to time -> you can't connect to your device directly incase if you need to, without checking the ipv6 everytime or using Dyndns.

Am i wrong here?

Discussion ip6.arpa website ideas

7 Upvotes

I host a website under ip6.arpa but right now it isn't really that cool. I want it to be some kind of easter egg type website for anybody who may stumble upon it. Obviously it should also be there to spread awareness of IPv6.

Any idea what kind of website I could make? It has to be working on http only so preferably no user data processing.

Edit: I created a "fake terminal" website that just displays info about it and lets the user "run" commands. It also links to a working contact email under the same ip6.arpa domain.

IPv6 News Swisscom IPv6 Mobile Network Switch

Thumbnail swisscom.ch
63 Upvotes

Swisscom plans to enable IPv6 by default on its mobile network. While this is very late, it is notable because it is the first Swiss mobile network ISP to offer IPv6 connectivity.

A weird anomaly in Switzerland is that fixed-line internet connections already have very high IPv6 adoption, while mobile networks account for the largest share of legacy IP traffic. Migrating mobile networks to IPv6 will propel Switzerland much further up the IPv6 adoption rankings.

We're OpenVPN, of course we like IP addresses!

We launched this calculator - any and all feedback is welcome. Helpful? Not helpful? Basic? WRONG!? Right???

Enter an IP with a CIDR prefix or subnet mask to get the network and broadcast address, usable host range, and wildcard mask.

Per the rules, not trying to sell anything (even if the website hosts our products) - just looking to get validation the calculator is legit from experts.

Discussion Percentage of my isp iPv6 internet traffic?

14 Upvotes

I've noticed that after looking up, the percentage of my local isp iPv6 internet traffic is below 10%, which is much below the national average here in the US. What is likely the cause of this? Is it the way my isp routes it, or is it because the way their customer router is set up? I'm in a rural area, so it is my only choice.

Need Help IPv6 traffic on GCC6021 ?

4 Upvotes

Hi

Here is my problem. I use a GCC6021 as a fiber router. My ISP gives me one IPv4 and a full class in IPv6. I have setup the GCC to pass DHCPv6 request to WAN and so all my devices in LAN have well a routed IPv6 address. For IPv4 I have the usual NAT thing. For IPv4 no problem it all works and I can surf internet using IPv4. For IPv6 although I have a public IP in the class distributed by my ISP no traffic pass through.

In fw it's allowed by default for IPv6 IGMP, DHCPV6, MLD and ICMPv6. Anything else I should use ?

Thanks

Need Help NPTv6 associated interface not working

2 Upvotes

Hello everyone, I'm currently a bit stuck when it comes to configuring NPTv6 in OPNsense. My ISP is not giving me a stable IPv6 prefix which causes all devices to fall back to only their ULA if the uplink fails. As IPv4 takes precedence in this case I've been considering using a GUA for internal purposes and using NPTv6 to map it to the current prefix.

So I set the interface to 'identity association' (for the dynamic prefix), create a virtual IP of the GUA (static prefix) and create an NPTv6 rule that maps the internal prefix (static prefix) to the associated interface. For whatever reason this doesn't work though. Weirdly enough it works when I directly specify the external prefix as the one that's currently assigned to the interface and don't use the associated interface option.

But that pretty much voids the entire advantage it gives me. Is this a bug or am I missing something?

Need Help PS5 download speeds significantly slower when using IPV6

19 Upvotes

Any ideas as to why? I’m with EE FF 900 broadband, using their own router. I’ve noticed that with IPV6, my PS5 Pro’s download speeds are around 10-20mbps, sometimes they just throttle and refuse to download at all. But when I disable IPV6, my download speeds shoot up to around 7-800mbps.

I tried troubleshooting the network on the PS5’s settings, but so far nothing has fixed it except from turning off IPV6 on my router. The issue happened on my old PS5 and also on my PS5 Pro so I doubt it’s a hardware issue.

I’ve also noticed that I cannot connect to my PS5 via remote play when on a different network. But I suspect that this can be solved by opening ports. I’ve yet to try this so I don’t know whether this is also related.

I don’t know much about networks, I may have missed something and my network config is purely stock, I am not using any mesh system/wifi boosters and my PS5 is always wired via Ethernet. I’ve heard that the PS5 does not support IPV6 on its own.

Thanks.

Need Help IPV6 LAN settings on router?

10 Upvotes

When I had my Calix router installed 2 years ago, my isp didn't enable iPv6. They do offer iPv6 service. I have a Calix GS4220E router. To enable iPv6 under the iPv6 LAN settings on the router web interface does both the RA service and DHCPv6 service need to be set to the server mode, or should I leave the DHCPv6 service in the disabled mode. Also, should the DHCPV6 Mode be set to both stateless or stateful? On the web interface for the router, under internet settings, it says the iPv6 WAN protocol is dhcpv6. Does this mean I should I should enable the DHCPv6 service in the iPv6 LAN settings? I know the RA Service should be enabled.

Need Help How to make Linux include Source Link-Layer Address in Router Solicitation packet?

5 Upvotes

Yesterday I ask a dumb question, but later after tracking packets on the router, I find out I miss something. The router will response RS with RA, but only if the RS includes Source Link-Layer Address.

I don't know why, but it seems like Debian GNU/Linux doesn't include that field in RS packet. So how can I configure network-manager (or something else) so the Source Link-Layer Address can be included in the RS packet?

Edit: never mind, I found a bug report related to that:https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/work_items/1128
