ChatGPT пристыдил меня за то, что у меня мало VLAN'ов.

Надо больше, говорит. Паранойя твоя недостаточно параноидальна, говорит.

А мне ему и сказать-то кроме "ну бля, ну мне лень" нечего 😢

Le gars annonce la suppression de plusieurs centaines de postes, mais en 30 minutes, les mots "plan social", "PSE" ou "licenciement" n'ont toujours pas été prononcés. En revanche "réorganisation"... à la pelle. #Vlan

Industrial network a mess? Our switch fixes it:

✅ IGMP snooping – Multicast only to who needs it
✅ Ring network – No downtime
✅ VLANs – Secure segmentation

Keep your data & video streams flowing smoothly.

¿VLAN y Segmento IP son lo mismo? 🤔
En el mundo de las redes, solemos usarlos como sinónimos, pero entender su diferencia es la clave para pasar de "memorizar" a "diseñar" redes de verdad.

Edit: it's solved, most probably it was a combination of 2×PEBKAC, unclear terminology of an old switch, and wrong assumptions what OpenWRT does by default with DHCP on a VLAN interface.

Dear #AskFedi, #networking edition,

If someone's interested in helping me out with VLANs I have made another post on the #OpenWRT forums.

Una guida di cui sono orgoglioso, non penso ne esistano molte in italiano, in cui illustro dettagliatamente la configurazione del mio homelab, analizzando i componenti hardware e le scelte che hanno guidato il mio progetto. Spiego come configurare degli switch gestiti, installare e configurare Proxmox e OPNsense, e come segmentare il traffico di rete tramite VLAN, oltre ad eseguire il backup della configurazione di OPNsense sulla propria istanza di #Nextcloud

Plex video bị giảm chất lượng vì bật “Relay” và VLAN cấu hình sai. Máy Apple TV trên VLAN thiết bị, server Plex trên VLAN bảo mật → Plex xem như kết nối từ xa, tự hạ xuống 480p. Tắt Relay, mở quy tắc firewall và thiết lập “local networks” (192.168.0.0/16) để truy cập cục bộ.

I wrote an elaborate post about my #VLAN problems¹ on the #OpenWRT forums.

It took one hour, four posts and two users to be assumed “like a clanker” because of a single sentence.

Population of fucks to give #AI and techbros increases.

Edit: the forum's staff have hidden my answer where I called the accuser a “wanker”, which – fair, but also locked and delisted the whole topic. Which baffles me.

Dear #AskFedi, #networking edition,

do you have an idiot-proof, Simple English, image guide to #VLAN with #Linux and #OpenWRT?

I've tried with a VLAN-aware switch, then I made that switch unaware of the VLAN. Then I connected my router and PC directly with an ethernet cable, set both to the same LAN (by default) and VLAN, set `tcpdump`s to both, and whatever I do the VLAN shows no traffic (ensured same VIDs) and non-VLAN shows regular DHCP requests (I didn't set up DHCPd).

Had half day off today.
Thought I'd "simply" set up some #vlan: one main, one #IoT, and one for my #poe ip cameras.
It took some work to set it up on my #GL.iNET #Flint3 #router, my
#Linksys #LGS528P was simple to setup
But after some tweaking (8 hours later) it seems all is now going well.
Even @homeassistant works in the new setup

edit: at the current DB size and the 100Mbps #VLAN, it'll probably take around 20 minutes per replica to recreate them. The primary is still active :)

New 30min. video from #TheSerialPort: "The hidden story behind the Virtual LAN":
https://www.youtube.com/watch?v=Lq1zpdbOmXY

Has a nice, simple introduction into the concept of #VLAN s. And features some interesting ideas that people explored before - and after - this became a standard.

Bạn muốn cách cô lập camera & IoT khi router không hỗ trợ VLAN? ✅ Dùng switch quản lý có VLAN và cấu hình mạng con riêng cho thiết bị IoT. ✅ Dùng router phụ (travel‑router, GL.iNet, Raspberry Pi) đặt dưới router chính, tạo subnet riêng & firewall rules. ✅ Kích hoạt “client isolation” trên Wi‑Fi hoặc thiết lập rule chặn truy cập Internet cho địa chỉ MAC/IP của IoT. Những giải pháp này cho phép thiết bị chỉ giao tiếp nội bộ mà không cần thay router. #Networking #IoT #VLAN #Mạng #CôLập #Router

@stepech @homelab I segmented my #homelab a little more lately.
#DMZ for internet-facing services
DMZ for services reachable from other #VPN sites
Rather isolated #VLAN for #IoT devices
Dedicated VLANs for #clients, #servers, home office and network devices

Not every VLAN is available via #WiFi.
