#vlans — Public Fediverse posts

PVST+ enables per-VLAN STP on Cisco Catalyst trunk ports with dot1q encapsulation. Set root bridge priorities per VLAN using 'spanning-tree vlan [vlan-id] priority'. Runs separate IEEE 802.1D instances with Cisco BPDU tagging. #vlans #snippet #cisco

Isolate tenants with Private VLANs on Cisco IOS/NX-OS. This config creates a PVLAN domain (primary VLAN 200, isolated VLANs 201/202), using promiscuous uplink and isolated/community host ports to restrict inter-tenant traffic. #vlans #snippet #private-vlan #tenant-isolation #ValtersIT

Packet captures are great since they show you all the details. For example, why is some stuff coming over as VLAN 10 when it should be 20?!

I have some misconfigurations I need to sort out between my router, switch, and endpoints. That’ll be a project for this weekend though, not tonight.

🚧 Ah, FreeBSD 15's new "bridging" act—brought to you by the same innovators who think deprecating features without a plan is a cool party trick. 🎩 VLAN support? Check. Confusing sysctls? Check. Of course, they graciously leave future headaches to sort out the whole router-on-a-stick mess. 🎉✨

Was ich gar nicht wußte: Bei #Vodafone bekommt man mittlerweile einfach so ein /64, ohne das irgendwo beantragen zu müssen.
Und es funktioniert noch dazu, kein Gehampel mit #tunnelbroker mehr, der #Mikrotik macht das sauber inklusive Sonderlocken wie "ignoriere die Nameserver, die Vodafone Dir aufs Auge drücken möchte, nimm den #pihole!"

#ipv6 wie es sein soll. Na gut, größer als /64 bekomme ich als Privatkunde wohl nicht, d.h, #Vlans im Heimnetz gehen dann eben nicht, jedenfalls nicht mit v6.
Irgendwas ist ja immer, für jetzt bin ich zufrieden.

Managing #OpenWRT via #Ansible is a breeze. I just love the fact that all the settings, all the #firewall rules, all the good stuff is configured with config files.

I've created 6 #VLANs, all of them completely #isolated, with a few allowed traffic rules. I've even isolated the #Windows #PC of my roommate inside of the #trusted #network.

Now his #XiaomiTVBox can't scan the network anymore (yes it actually does that. I've noticed it while working on my packet monitoring project).

#OPNsense users, it is time to migrate your legacy #IPSEC VPN tunnels to the new connection setup. The Legacy IPSEC feature will be deprecated in 26.1.

I have updated my IPSEC post [1] with the new connection settings. The migration was not straightforward and required some changes, but it is not complicated either.

A little gem here is the #CIDR subnet mask notation used for Policy Based Routing, which allows multiple subnets (#VLANs) on both sides to be automatically routed, without the need for ongoing changes to tunnel settings.

It's Sunday! 🌝

Don't forget to touch grass! 🤗

Because problems tend to resolve themselves on long walks.

- Optimizing your #nixos config can wait.
- Dealing with those stupid #docker containers too.
- Halting your quest to perfect #vlans won't kill you.

Everything will ultimately be done by your future self. 👊

Just allow him to breath from time to time.

I’m looking for a wireless access point that supports VLANs - in the sense that I can create different SSIDs for different VLANs or I can specify which client goes onto which VLAN.

Any help appreciated as I’m drowning in marketing fluff at the moment.

And boosts always appreciated.

My IT career was in desktop hardware and operating systems, so setting up my 2 Omada WAPs and networks has been a hair-pulling affair.

Can someone point me to a SIMPLE guide to setting up a home network, a local-only IoT network, and a guest network across two WAPs with an Omada gateway? I think I’m getting screwed up with VLANs and PVIDs and ports (Oh, my!), but every guide I’ve seen is over the top with info.

EDIT: I FIGURED IT OUT! 😎

Haven't really been on social much lately...but that's not to say I haven't been working on some side projects!! 🙃

Finally got around to setting up a new firewall device running #OPNSense, which I'm really liking! Finally able to start utilizing #VLANs and building up my #Proxmox servers!

...and of course, I can't fail to mention that I FINALLY snagged a new #MacBook Air! This thing is on par with my ol' MBP but stays charged 3x longer! #awesome :apple: 🙌😎

Has anyone had experience with #hpe 1920-48G Ethernet switch? I've got one and am struggling with setting up VLANs and stuff.

I'm pretty sure it's a level 3 switch, so if anyone knows a general setup for these to make multiple VLANs be connected to main internet connection then reply please.

Unifi network devices allow you to easily create and manage VLANs. It is super easy and convenient even for home and small business networks. But did you know that by default network traffic between VLANs is allowed?

Fortunately, it is very easy to block network traffic between VLANs via firewall rules. You just need to know how network works. Or you can just follow my guide and do not need to know the details of networking 👍 #unifi #ubiquiti #vlans #networks #firewall #cybersecurity #tips https://www.cswrld.com/2023/12/how-to-block-traffic-between-vlans-in-unifi/

@strobelstefan I was also thinking about this option as well.

One of my use cases is to share also some files or folders with others. Additionally I have my parents where their phones (mainly photos) will be backed up as well. I don't think I can explain them how to use a VPN 😂

Since my home network is a bit more advanced I'm confident I can expose it without risking to much.

I have a #UDMPRO with #VLANs and #firewall rules set up. Think will create an own VLAN and put the server into taht

After seeing @ironicbadger's video on Homelab Networking(https://techhub.social/@ironicbadger/111298632610343382) I think I had an epiphany for my #homelab. This is a new venture for me and it's quite fun, but I am rusty with #networking configuration. Buuut, I think I was doing it wrong. I'm going to setup #Proxmox to be on the same LAN as all my other day to day devices. Then I will setup #VLANS in Proxmox to isolate those services. #Opnsense being the firewall managing that VLAN. Does that sound right?

My head hurts. I’ve been reading about #docker #networking. Can’t quite get my head around #vlans for containers.

Does docker need to assign IP addresses? Or can I simply create a docker network that tags traffic with a vlan tag, and let my network do it??

It was a steep learning (re-learning) curve to set up this gear, but great fun to dive into!

Uff, ganz schöne Umstellung das #Mikrotik Zeug. Was bin ich froh, das die #Telekom so lahm ist, mirs Glasfaser zu legen, da hab ich wenigstens Zeit, das richtig zu basteln, was ich so plane.

Task heute war #vlans hinkriegen.
Nunja, zumindest hab ich wohl vlan-mgmt jetzt soweit, das ichs tagged auf allen Mikrotiks habe, und auf dem Port von meinem Laptop ebenfalls Tagged dazu, zu dem normalen Kram das da läuft.
Morgen dann die anderen VLANs einbasteln.

Der "Safe Mode" in der #winbox der Mikrotik ist echt hilfreich. Falsche Config und ausgesperrt? Kurz warten, und Configreset erfolgt.

I am going to take notes as I do it so that I can write up a little how to later. I'm not just doing a basic input output router. We're doing #Wireguard, #VLANs, #iPerf, #PiHole, #NFS, and #Awall (Alpine Firewall)

New #ISP provided me with all the credentials and parameters I need to setup my own router, a public static #IPv4 and a full /48 static #IPv6 subnet 🤩

I can't wait to start messing with #VLANs and all that fun stuff
