I did get it working, but then I had tonnes of issues with dropped packets on my LAN. Stripped all my VLAN config away (only on the switches, not OPNsense) and all fine again.

lol

Thank You Anyway, all working now :-)

Thanks for all of the help everyone - It looks like I just had everything badly configured.

VLAN 10 all correct now - I think. Devices gets an IP and can get to the internet.

Although, I did have my firewall configured incorretly too :-)

Although I still dont get why the ports with VLAN10 are meant to be untagged.

This said, the insert dialog is messed up...

Thanks, Doh!!! :-)

For one, I do not see where VLAN 20 is going through your switches. They only have VLAN 1 (untagged) and VLAN 10 configured.

And you did not post the actual IP settings of your Ubuntu Desktop and your Proxmox host.

Also, if your Ubuntu Desktop is configured as usual, it will be untagged, so your port 8 of your TL-SG608E should be untagged for VLAN 10, not tagged. You have not shown your Proxmox config, so probably the management interface expects VLAN 10 untagged as well.

Review your VLAN tags and your switch configurations. 

Hi

The link I shared had all of that in, but the image won't embed from Google Drive, Google Photos or even Imgur. So let me try and explain.
- I havent created VLAN20 yet as just trying to get the Proxmox host and Ubuntu Desktop working in VLAN10
- They are in ports 7 + 8 on a TP-Link TL-SG608E switch.
- Other devices on that switch are untagged (another PC, another server and an TP-Link Deco AP)
- Port 1 is the uplink port to TP-Link TL-SG108E switch
- VLAN10 has an IP of 10.100.74.1/24 - Ubuntu has got 10.100.74.50 from DHCP and Proxmox 10.100.74.51
- My configs are
 VLAN: 1, VLAN Name: Default, Member Ports: 1-6, Untagged Ports: 1-6
 VLAN: 10, VLAN Name: VLAN10, Member Ports: 1, 7-8, Tagged Ports: 1, 7-8

Upstream - TL-SG108E switch
- Port 1 comes from the other switch above
- Port 8 goes to OPNsense Box
- Other ports: 1 goes to another AP and 1 goes to a TP-Link TL-SG605E (all untagged) with a PC and Xbox and another AP.
- My configs are
 VLAN: 1, VLAN Name: Default, Member Ports: 1-8, Untagged Ports: 1-8
 VLAN: 10, VLAN Name: VLAN10, Member Ports: 1, 8, Tagged Ports: 1, 8

Other points
- LAN DHCP is 10.28.74.1/22 and everything works fine
- If I put ports 7 + 8 into the default VLAN, they get an IP from LAN DHCP and work without issus

Hope that helps.

Please attach screenshots to your post. Some balk at external links...

I posted the link because no matter what I do, I can't get the image to show up in the post :-(

Thanks

Hello

I have been messing around with OPNsense to build a homelab and sure I must be doing something wrong.

I have a proxmox server and an ubuntu desktop both in VLAN10, after not getting IP's from DHCP for ages, they have magically got them now.

However, none of the devices can access the internet or ping each other, or even the default gateway.
1. Switches are configured
2. VLAN created
3. Default LAN rule copied and assigned to VLAN10

I really am pulling my hair out, can anyone help, please?

Cheers
