VLAN issues

[vlehemonet]

Hello,

I suspect an issue with my TP-LINK switch (case + thread open with tp-link), but i want to validate my proxmox configuration too.

Basically, I have a proxmox server with a couple of VMs/containers running, including my Pfsense who act as L3 router for my inside network and as internet router.

For informations here is my proxmox configuration :

My VMBR2 bridge is "VLAN aware" and bridge to enp4s0 physical port.

My VM is set to TAG frames with VID 2.

If i capture the traffic directly on my proxmox host, I can see my VLAN tag (on physical and bridge interfaces)

If I capture the traffic on the switch (monitor session) I cannot see the VLAN ID anymore,

Of course I got nothing if I run a packet capture on my pfsense as the frame is probably drop because of the VID missing

Here is the switch configuration :

interface gigabitEthernet 1/0/24
switchport general allowed vlan 2,10-14,99 tagged
no switchport general allowed vlan 1

T1600G-28TS#sh interface switchport gigabitEthernet 1/0/24
Port Gi1/0/24:
PVID: 1
Member in LAG: N/A
Link Type: General
Member in VLAN:
Vlan Name Egress-rule
---- ----------- -----------
2 N/A Tagged
10 N/A Tagged
11 N/A Tagged
12 N/A Tagged
13 N/A Tagged
14 N/A Tagged
99 N/A Tagged

As I said,it's probably a switch issue, but if someone see something wrong with my proxmox configuration please let me know.


Thanks,

Problem solved.

My vlan configuration was right.

The proxmox firewall was actif on my pfsense trunk interface.
