#nat — Public Fediverse posts

¿Facilitan otros ISPs salir de la NAT? ¿O te obligan a contratar una IP estática? Yo con #PTVTelecom estoy muy contento en ese aspecto. Fue llamarlo y me han sacado de la #NAT sin mayores problemas.

Te intentan disuadir, eso sí, con chorradas de seguridad y demás. Pero vamos, que el que lo pide sabe lo se hace. O debería, je je.

#Digi tengo entendido que te comes sí o sí el contratar la IP.

NAT is a hotel reception desk for the internet 🏨🌐

Your devices have private room numbers.
The outside world sees one public address.
The front desk keeps track of who asked for what.

New Networking for Humans post is ready.

#portforward #nat #OpenWrt #IPv6

Instead of a #portforward / #nat you shall just open ports with IPv6.

If you have a dynamic prefix this is an example of how such rule looks like. So it will even continue to work when you receive a new prefix.

Just make sure your DNS keeps pointing to the right address and BAM, you're a server operator, even on a dynamic prefix.

Have phun with #OpenWrt and #IPv6

As much as I love teaching myself IT material and do quite well at it, some concepts make my brain hurt. It took an incredibly long time for me to undertand #NAT #hairpinning. I am pretty chuffed that I understand it now. Since I struggled to learn it, I think I am good now at explaining it.

My I get your input?

@Pikapods they often think that #SelfHosting means "host it at home" while providers like #PikaPods allow simple setup, not #LAN #NAT considerations, and more resilience 😁

OMG! I don't know why I spent so long trying to muck with #NAT #hairpinning. Yeah, I R smart! It was so much easier to simply set up an internal #DNS server to have internal hosts access servers by their internal IP addresses. I wasted a lot of time. Argh! 😠

I am helping a friend chase a particularly troublesome and difficult problem and it seems to be related to #nat. I have to also figure out how #firewalld does its rule evaluation. I have a direct rule in place for finer grained control and it’s being totally ignored. What the *bleep*!!!

Как мы делаем онлайн звонки: Введение в WebRTC и LiveKit

Хотим рассказать о том, как мы делаем платформу для онлайн звонков и видео конференций с ИИ, но чтобы не слишком сложно было. Начнем с самого низкого уровня - с механизма передачи данных между клиентами в созвоне. В этой статье мы расскажем про WebRTC, NAT, STUN/TURN и немного про LiveKit

Почему порты стали «дверями» в сервер, и кто решил, что SSH будет 22

В 1995 году Тату Илонен написал письмо длиной с пост на Хабре и бесплатно получил номер ssh -p 22 user@host, который теперь знает каждый сисадмин. Но до этого порты были однонаправленными, чётные номера считались ненужными, а половина слотов вообще пустовала. О том, как порты стали «дверями» в сервер и что останется от них через десять лет, рассказал в статье. Читать

Сети База для начинающих

Микросервисы запускаются, контейнеры оркестрируются, а сеть… ну, она как-то сама работает. Негласное правило многих начинающих разработчиков и админов: работает — не трогай. Но ровно до тех пор, пока в продакшене не отвалится резолв DNS или база данных не станет отдавать странные таймауты. В этот момент сеть превращается в настоящую головную боль.

Something to consider about all of the efforts to sustain #IPv4 so far beyond its original shelf life. #NAT and #IPv6 were thought out at roughly the same time. NAT was a tactical move to stave off IPv4 exhaustion (at the cost of limiting the peer-to-peer nature of the Internet) and IPv6 was the strategic answer for scalable growth. The obsession human beings have to find any excuse to avoid change was highly underestimated. IPv6 took 22 years to become an Internet Standard and NAT became so entrenched that peer-to-peer networking became mostly unnecessary as long as we could continue to laugh at cat memes on our favourite platforms.

This brings us to #platforms. It’s getting harder to host anything ourselves anymore without paying a (usually foreign) IaaS/SaaS platform to do it for us. We now live in an age where data sovereignty and privacy are at the forefront of our thinking and maybe, just maybe, we want other options.

Is our obsession with IPv4 tying us unhealthily to platforms and sacrificing our freedoms?

#SaturdayMorningThoughts

🎉 Look, it's 2026 and we're still banging on about #IPv6 like it's the second coming! 🤣 Apparently, the entire internet is going to collapse under the weight of #NAT unless we make the switch to IPv6, because hosting your website from your mom's basement was the pinnacle of #innovation. 🙄

Chromecast said "Not connected to the internet", rendering it unusuable.

I drop all external DNS (and DNS-over-TLS) requests on my network.

Google (along with Chinese IoT spyware, Samsung, and others) now try to use their hardcoded DNS servers.

My network now fools them all, they think they get a response from their DNS, but it's really my PiHole that answers! NAT + Masquerading FTW!

Страшно, когда не видно: аудит сетевых устройств

Представьте, что вы не знаете, какие устройства подключены к вашей сети, как они настроены и что там происходит. Страшно? Ещё бы! Многие компании как раз так и живут — не уделяют внимания аудиту сетевого оборудования. А зря. Без такой инвентаризации невозможно ни нормально управлять ИТ-инфраструктурой, ни защититься от угроз. Мы наблюдаем в инфраструктуре клиентов это так часто, что поняли – нужно выдать базу. Мы – это руководитель практики развития MaxPatrol Carbon Константин Маньяков и эксперт центра безопасности (PT ESC) Данил Зарипов, и в этой статье мы будем разбираться в ключевых аспектах аудита сетевых устройств, его роли в построении эффективного управления активами и повышении уровня защищенности ИТ-инфраструктуры.

Как раздать десятки публичных IP сотням виртуальных машин и не упасть

Недавно в MWS Cloud Platform появилась поддержка Egress NAT. В статье разберём архитектуру распределённой системы трансляции адресов, почему мы выделяем порты блоками и как обеспечиваем корректную передачу обратного трафика в условиях ECMP-маршрутизации. Плюс как это всё переживает рестарты, потерю событий и рассинхронизацию и всё равно сходится к правильному состоянию.
