Re: Home internet service IPv6 traffic is all filtered even when using a Netgear LTE router. No port forwarding. Plz fix!

I say passthrough "works" more so because of client side issues then network issues. DNS can be sluggish (at least in Windoze), causing your browsers to fall back to v4 lookups. But if you are avoiding that screwy slow DNSfall back scenario (like on your phone), it works. Just frustrating. They should have known better. Sometimes it feels like the DOCSIS beta days. You can see there should be a better way to do things... butit just is not happening. Phones on T-Mobile use DNS64. So, you will always get an IPv6 response and address from DNS on a phone. This is not the case with TMHI. You will only get an IPv6 address if there is a AAAA registration for the host. For me, DNS is working properly with TMHI. My clients use IPv6 for sites and services that support IPv6. If I completely turn off IPv4 on a client, I still have connectivity to those sites and services. I even tested using DNS64 servers and turned off IPv4 and I had no issues with apps or service except for the T-Mobile digits app.12Visto0likes0ComentariosRe: Home internet service IPv6 traffic is all filtered even when using a Netgear LTE router.

I called before ordering the service and they told me this was possible - but I guess they lied. Front-line support are mostly useless and don't even know about double-NAT and why it is a problem for VOIP and many other apps. Does T-Mobile have any real network engineers? It seems like the people on this forum are better qualified. IPv6 passthrough with your router should be working. It does for me. But, that's a function of your router. If its not working, the issue is on the inside of your network. Its not with the gateway. But, if your VOIP service doesn't support IPv6, using passthrough won't help. Also, I don't have an issues with VOIP services. In the past, I have heard of others having issues. But, I do not.15Visto0likes0ComentariosRe: Home internet service IPv6 traffic is all filtered even when using a Netgear LTE router. No port forwarding. Plz fix!

This particular 172.58.0.0/21subnet has been reserved/announcedsince 2016 (was 172.58.0.0/15 for about 10 months beforehand). So no... they didn't exactly become a V6 only network. They have been maintaining active v4 IP's for quite a while... this particular subnet since 20160825. The history heredates back into 2012, where it notes a different subnetdescribed as internet backbone. Their TRANSIT may have moved over to v6... but they have maintained their v4 assignments. And yes, the gripe includes the inbound traffic.. but there is more to it. The geo data assigned to my v4 addresses put meout of state... which monkeys up functionality for some services (sometimes Charlotte, other times Atlanta--I live inFlorence, SC). It is also monkeying with game traffic as well. People have posted here those problems go away when going throughtheir phones and/or hotspots. In other words... the v4 subnets the "normal" cell devices are using have more proper functionality. So again... they are perfectly CAPABLE of a better dual-stack implementation... but CHOSE otherwise. I have had the same issue with the geolocation. But, mine occurred on both ipv4 and ipv6. And, it also occurred on my phone when its not connected to TMHI. I called the number listed on the trashcan's web interface and they fixed the problem for me on home internet . I'm still a little off. But it close enough now. I agree their dual stack deployment could have been better and probably will get better. Its likely still a work in progress. Its also interesting DNS64 is used on the phone network while it isn't on home internet. I'm curious why thats different. As far as inbound connectivity, hopefullythats coming. I do not believe it is disallowed globally as others have said since Calyx customers on the MiFi are able to enable inboundIPv6 traffic, Unfortunately, it doesn't look like you can manage the traffic by port or address which is a security issue. As such, if inbound traffic isever allowed, I will probably always keep a personal router between the trashcan and my network.9Visto0likes0ComentariosRe: Home internet service IPv6 traffic is all filtered even when using a Netgear LTE router.

djb14336 wrote: @Locutus Not sure you caught all that was posted in there. I ran a generic search on a specific name (T-Mobile USA), which returned like a dozen unique ASN's. That why no way encompasses the entirety of their organization's provisioned addresses. Remember, they also just picked up allthose Sprint assets as well, which also has over a dozen ASN's provisioned. Just ONE ASN had over 12million v4 IP's reserved… ...as in provisioned for their exclusive use. How many are actively in use, and how many could be repurposed is an important question. For example, what if they flipped the scriotnonncell and home internet provisioning? Put all the cell/hotspots into the funky XLAT/CGN layer, and give all the vacated IP's to home internet. Thinkabout thisfor a moment… Why is it sooo important to reserve all that super high speed bandwidth and port traversal capability for those mobile devices, as opposed to the home internet users? What is the rational for prioritizing north of 100-200mbps down and 20mbps up as well as a properly functioning network model for mostly single user device cell usage while denying such important things to a home NETWORK. They very well COULD have set this up properly… ...but for whatever reason, they CHOSE to set it up this way. They didn't HAVE too. But they DO have to. They all HAVE to. T-Mobile put the money and time into switching to IPv6 long before they rolled out home internet. They didn't do it just for fun. After doing so, when it came to home internet,I imagine their thoughts were: Everyone hasto switch to IPv6. We are already where we need to be. Why do we want to roll back to IPv4 while our competitors.are still trying to switch their networks over to IPv6. In my opinion, the factT-Mobile was able to switchIPv6 earlier than most, shows them as a leader. Since they have, most of my traffic is IPv6. And, like I said, please excuse me if I am assuming here, I don't think your complaint is about IPv6. Your complaint is about not having inbound connectivity. And I agree with that complaint. But that is a different issue IPv6 or not.10Visto0likes0ComentariosRe: Home internet service IPv6 traffic is all filtered even when using a Netgear LTE router. No port forwarding. Plz fix!

I wish I had somone who would come up with excuses for me everytime I mad poor choices at work. I'm not making excuses. I'm just stating the realityof running out of IPv4 addresses. I'm sorry you don't like reality. Being on an IPv6 network shouldn't be a problem. However, if your real concernis you cannot have inbound connections, that I understand. Its a brand new service. Hopefully, T-Mobile is listening and working on that. In the meantime, there are workarounds. If you don't want to use the workaroundsuntil T-Mobile allows more flexibility, I would suggest you use another service until T-Mobile does.15Visto1like0ComentariosRe: Home internet service IPv6 traffic is all filtered even when using a Netgear LTE router.

djb14336 wrote: IDK about that angle of them not having/not able to use IPV4. A Basic dig on their ASN's shows they have a crap ton of IPV4 registered. Over 12 million on just ONE of their USA ID's (AS21928). Granted, some (like AS393494, that appears to be tied to TVision) only have 60-70k... but whois to say how much is actively in use, and how much could be repurposed? But theyDO in fact have and use IPv4. Thequestion is why is it not implemented for home internet instead of the screwy XLAT464 crap. Who knows why they still own these subnets. Owning them, however,doesn't mean T-Mobile isn't an IPv6 network. Indeed they are. They completed the transition years ago. XLAT464 is of course used for compatibility with IPv4. Some of these IP's are needed for that. At any rate, let's just saythey would make the decision to switch back to IPv4, these block's of IP's wouldn't come close to the number of IP'sneeded to support IPv4 for all the devices on their network. And the problem only gets worse as their network grows.7Visto0likes0ComentariosRe: Home internet service IPv6 traffic is all filtered even when using a Netgear LTE router. No port forwarding.

mobileman82 wrote: You can still buy/rent IPV4 space. If Tmobile has that defeatist attitude this service wont sell well…. Maybe it won't. Maybe they arecounting on there being enough customers who don't need inbound connectivity. Who knows. So far,they are on track with their home internet additions for the year. For me, I'm saving $720 a year with better speed. I don't care about having to use aVPN to fix the inbound connection issue especially since, even with the VPN, that traffic is faster than what it was before. I agree: Its not ideal. But its a better solution than what I had with Comcast.17Visto2likes0ComentariosRe: Home internet service IPv6 traffic is all filtered even when using a Netgear LTE router. No port forwarding.

mobileman82 wrote: I don't want a wifi hotspot I need "home internet" as this is sold. There is no real solution, only finnicky hacky workarounds such as VPN. Tmobile could have used Ipv4 if they wanted that is not even a question. Not supporting ipv4 breaks many critical components of the internet. I'm not how you know Tmobile could have used ipv4. T-Mobile stopped using ipv4 on its network years ago. Spending the time and money to bringipv4 back just for home internet customers probably didn't make sense. Also, since the global internet isout of ipv4 addresses, I'm not sure where you think T-Mobile will be getting these ipv4 addresses to hand out to each customer. IPv4 still works with T-Moblie. It just cannot be used for inbound traffic.12Visto0likes0ComentariosRe: Home internet service IPv6 traffic is all filtered even when using a Netgear LTE router. No port forwarding. Plz fix!

If you need a work around, you can connect up your own router to the gateway and use a VPN service for about $5.00 a month. What a dumpster fire. No Ipv6 or Ipv4. Might as well call this one way internet. This breaks multiple internet standards and expectations for an internet provider. Ipv4 is still crucial in 2021. Borking Ipv6 is not acceptable. Well, I don't know about internet standards and expectations for iPv4 since we have been out of ipv4 address for years now. Due to this fact, T-Mobile made the smart decision to switch to IPv6 several years ago. After all, withno more ipv4 addresses available, what choice did they have? At any rate, the lack of ipv4 isn't really the problem. The problem is not being able to manage inbound traffic under IPv6. If that is a problem for you, there are work arounds until T-Mobile allows this functionality on TMHI. Another option is to useCalyx. Calyx uses the T-Mobile network and the T-Mobile MiFi M2000 and it allows inbound IPv6 traffic.10Visto0likes0ComentariosRe: Home internet service IPv6 traffic is all filtered even when using a Netgear LTE router.
