Slovenian ISP T-2.net also violates local network neutrality laws here by requiring customers to pay extra to unblock some special TCP ports, like 25 and 53, meaning they block selfhosting email and dns servers without additional payment. I filed a complaint to the national regulator AKOS. They first responded with agreeing with me, but nothing was fixed for many months, and upon emailing the regulator again, I recei…

Blocking port 25 is perfectly reasonable. There are no sane and legitimate reasons for running an SMTP server on a residential connection. Even most server providers will block it unless you give them some very good reasons. Blocking 53 is just weird though.

Define "residential connection".

There is no such thing. A connection to the internet should be equal to any other connection to the internet, modulo BGP peering. Noone has a right to dictate what services I run or don't run, what protocols I speak or don't speak, what traffic I accept or deny, but *me*. That's the whole point of being on the internet rather than Prodigy or Compuserve or something.

The physical location of that connection is irrelevant. Maybe I feel my servers are safer in a datacenter. Maybe I feel they're safer in my basement. In my case, it is very much the latter, and again, you don't get to make that call. I do.

Telekom is a bunch of strange folks. I lately was not able to send mails, from my private mail servrr to my fathers telekom mail. After investigation I found out my server got blocked. After a decade of working. I mailed them, and they told me to register my mailserver with them. I shall tell them what mails I will send from there and about what content. I couldn’t believe my eyes.

Does anyone self host email anymore successfully? I'm honestly asking. I would like to but it seems like a full time job trying to keep it running. Are there halfway solutions where maybe you own the service and domain and it runs somewhere trusted?

Fun fact: Deutsche Telekom just started their ad campaign "being better in the best network" (https://www.telekom.com/de/medien/medieninformationen/detail...). While they have the worst network of all, especially when it comes to peering (30% of the internet is just slow over Telekom but fast over Telekom + any VPN).

Calling this "paying to unlock ports" is disingenuous. I'm also a T-2 customer and have run into this before. They block ports on dynamic IPs, but if you pay +2€/mo for static, this is unlocked. This seems reasonable. If you're not paying for static IPv4, you're paying for "internet access", whether that's a rarely chaning dynamic IPv4, a constantly changing IPv4 or full CGNAT. Would you also say your mobile phone op…

I've been told there's a law that my mobile phone operator has to turn off all firewalling on my connection if I ask.

I don't know about that law, but GP's point was that you don't get a public IP anyway, firewall or not. And with this NAT in place, you can't ask them to forward specific ports to your equipment.

In France, CG-NAT is getting widespread even for fixed, FTTH links. I'm typing this connected to SFR, which provides a static IPv6 /56, but IPv4 is behind CG-NAT. I can't host anything on IPv4. I think there's an option to get a fixed, internet routable address, but not on the "discount" plan I'm on. I hear you maybe can ask support to get you out of CG-NAT, but that doesn't seem very reliable.

Free (local ISP), by default, doesn't give a static IP for fiber, but you can ask for one for free through your online account page (you just need to tick a box).

I own a FTTH connection to Telekom since 2018, as the only provider in my street, allowed to install an internet connection (only glass fiber). Since then, I have always used my own device and I maintain a GitHub Snippet in how to connect OpenWRT modem (and by extension, any other modem that supports pppoe), rather than their Huawei SpeedPort crap or the more expensive Fritz Box). Link to Gist : https://gist.github.c…

For PONs you can get a programmable SFP+ and clone the manuif, devid, and password into it.

Yeah, but they're the only network when you want to have cellphone reception outside of dense cities. You can completely forget O2 and Vodafone if you go hiking/skiing in the Black Forest, or on the Beach at the German Islands.

Also Vodafone outsourced their peering to a subcontractor, and doesn't do any public peering at all anymore. So I guess Telekom still isn't the worst Network at all

Im actually quite okay with that. Why should I have to pay for specialized hardware that won't be usable if I move and the new apartment uses DSL or docsis.

The "glass fiber modem" is an inherent part of the GPON network. These are complicated. The "P" stands for "passive". Yours and and up to 127 other houses are all on the same "light domain" i.e. the downstream is passively split, and the upstream is passively combined, in optical boxes that don't even have electrical parts. This needs crazy accurate timing for the upstream. The head end needs to know the exact delay…

I cloned mine into an SFP+ for a handful of microseconds of latency improvement.

Peering just means that two AS physically connect to each other directly. Whether this peering is paid or not is independent from the technical implementation. Just nearly everybody except Telekom is doing this on a liberal and informal not-even-handshake basis. On ISP scale, you either invest in infrastructure, or pay rent for network ports or cross-links, and you generally want your traffic usage to be smooth witho…

My cellphone is very much subordinate to my provider, not a peer. DT thinks it's important enough that it can extort everyone.

> This also describes transit and describes getting internet service at home.

Well no. Transit means that you use another AS (usually by a larger ISP) to get connectivity to a certain AS. And as for your internet service at home, unless you announce an AS, you are not peering with anyone.

Sure. Highly successful even, I would say. I can deliver to Microsoft and Google.

Not sure though what the magic ingredient is. I've had the IP address for 7 years before I decided to use it for mail, after one quick mail to Cisco's Talos stuff everything was fine. Software is Mailcow. Hosted at Hetzner in Germany.

And still, I cannot deliver to T-Online, so there's that.

Another T-2 customer here. I never ran into issues with port blocking (but didn't try 25/53), even more, I had a "free" static IPv4 on DSL before we got the fiber line, but I've lately been noticing random connection slowdowns. Never had significant slowdowns with DSL. I've talked to a few people (Telemach customers) who told me it happens every now and then, they call the support center that tells them to restart th…

Telemach is also funny in net-neutrality regard:

Article 7.2 of their terms of service https://telemach.si/download/terms/splosni-pogoji-poslovanja...

It states that customers are bound not to setup servers on their internet connection point without prior aproval by the ISP. It sounds against the law to forbid this, albeit ianal.
