Looking for a little help here, and im a bit of a newbie so bare with me! I cant get two vlans to communicate with each other - i have tried creating firewall rules, following vlan videos on repeat, however no success. I’m trying to create a 3 VLAN scenario as follows: VLAN1 - 172.16.0.0/24 ( Wir…

Inter-VLAN traffic should be allowed by default, as far as I understand. So, unless you have have setup a rule that explicitly drop all traffic between VLANs, it should be allowed.

I have reset the router and redone configuration multiple times - it does not work.

Strange. What is the network topology and how are the associated ports on router and/or switches setup?

Can you take a screen shot of the firewall rules so we can see if there are any potential misconfigurations? It sounds more like @ebuckland81 mentions that there are interface configurations that needs to be done such as allowing VLANS over a trunk/access port.

Issue is for the user to follow the manual. I reset everything to defaults and re followed videos step by step - now working properly. I think my issue was i did not assign the vlan to the wifi password. Thanks for quick replies!

So slight update - i thought all was working however it seems i cant communicate from vlan 2 back to vlan 1, however i can now communicate from vlan 1 to vlan 2. Any suggestions?

Are you using altapass (ppsk)? What type of network have you chosen for vlan2? I think we will need the pictures of how the settings are to get a better understanding of the setup itself, also if you can show the fw rules you have.

Yes im using altapass - this was my initial issue as I was not able to get a conventional vlan setup to communicate at all before seeing this feature in a tutorial video. Network for vlan2 is Standard. VLAN has been set here. Firewall is default settings, no modifications have been made. I tried c…

Would you mind sharing the topology of network devices and port settings? Maybe someone can spot something being off by looking at that.

I must have been tired last night - you guys are 100% correct to say that it all should work out of the box with no setting changes. When testing i first pinged my proxmox server, no response. I then pinged a windows 11 device, no response. This is what lead me to believe I was only able to communi…

Great. Happy that you found the issue

Now that you mention it, I should have had that fresh in mind as something similar occured just recently:
