#Nat

2025-06-29

One of the great and wonderful things about the early #Internet was that you could send a packet, containing whatever bytes you want, to *any* computer, anywhere in the world, at will and without ceremony.

Then dynamic addressing and #NAT came along and ruined everything. 😭

Dos máquinas virtuales corriendo, un #Devuan como cliente, un #Fedora como firewall #nftables, con redirección de tráfico, #nat, para simular el caso real, y la imagen del esquema de red simulado.

Casi 10G de consumo de RAM para grabar una clase explicando cómo montar ese firewall en Fedora para que Devuan pueda hacer ping y navegar en Internet 😆

Todo el crédito es de mi vieja computadora de escritorio corriendo #ArchLinux 🖥️ 🙂 🐧

Do I have anyone within my reach who would be willing to help me debug a DNAT issue on OPNsense?

I can sincerely say that it's *probably* trivial, and I am *probably* just missing something obvious; but it's not obvious when you're not quite sure what you're looking for. Reading the documentation, browsing the forum and searching the web has not led me to find a solution.

Boosts appreciated.

Kafka через NAT

Иногда появляется необходимость обращения к брокерам Kafka из другой сети через NAT. Но, даже если NAT настроен корректно, то при попытках подключения, обратно возвращается ошибка о том, что брокер недоступен. Хотя ping и telnet по нужному порту проходят. В статье мы подробно разберем, как необходимо настроить Kafka для того, чтобы к системе можно было обращаться через NAT.

@lycanmatriarch That does sound weird. The LAN-side-of-NAT IP (typically RFC 1918 space) should only show up on the LAN side of NAT. That's kind of the point of NAT.

Are you *sure* it's your Plex box originating that traffic, and not just some other machine on the network you're on that happens to have the same IP address? Maybe something in the Plex web UI which happens to include a request to its internal IP address and which (obviously) does not get rewritten by the NAT at your home?

Hey other #network folks I have a weird #firewall and #NAT question. I'm looking at the firewall traffic log where my work laptop (I'm in the office) is the source, and I'm looking at the traffic connecting to my home plex server.

The plex server is a private IP behind NAT. In the log I show the putbound traffic from my work laptop to my home router IP, but I also see a following entry with the private IP that my router is forwarding plex's port traffic to. I thought anything done behind NAT wouldn't show up, especially because I'm only looking at the initial communication out, and not the return communication from my server to my me. Is my understanding of NAT wrong?

What Docker did was to intellectually limit the creativity that users could have had with containers, funneling everyone into the most trivial of network use-cases. When everything is server-client, it's really hard to develop peer-to-peer or avant guard applications.

The parallels to #LegacyIP and #NAT are staggering, as they too stymied progress in other, not-yet imagined scenarios. #IPv6 should have been the go-to for hyperscalar from day-one. That it wasn't is forever a travesty.
