vlans stop working after using new hardware

moosport

After replacing existing hardware which vlans were working. With new hardware, vlans are broken.

config was restore after new hardware was plugged in. interfaces were reassigned the new WAN and LAN.

Devices plugged in are handed the correct IPs for the vlan tagged at the switch.
But it cannot ping devices on the same vlan. or the gateway.

There are no change to the firewall rules. It should not be affected by interface change.

Do I need to recreate vlans in pfsense?

After some research, the following changes were made to the switch

Change port Untagged VLAN to 50 both ports.
Change VLAN Membership - By VLAN participation to excluded for both ports.

Now devices can ping each other. But ping to pfsense still do not work.

Wireshark is your friend for this sort of problem, to see what's killing the VLAN.

You don't say what was replaced so anything I say might refer to the wrong hardware. However, first off, you have to create the VLANs in pfSense if they aren't there already. Then, the switch must be configured for the VLANs. Based on your very limited description, my guess is the switch has not been configured for VLANs.

Old router m920q was replaced with X11SDV-4C-TP8F.

I had to recreate the interfaces for vlans after backup was restored in addition to remapping WAN and LAN.

Pfsense->aruba 1930->unifi16->unifi AP

These setup works prior to replacement.
To troubleshoot, 2 ports on Aruba were set to guest vlan. Uplink port is trunk to allow all vlans.

I had similar issues when I switched from my A1 SRM – 2558 to Netgate 4200. There were inconsistencies, I tried to correct a few to get the basics going. But, I just ended up doing a factory reset on the 4200.
I’m thinking if it’s not the exact hardware on the restore from to the restore to, things go a little sideways.

I was having issues with the restore with the webgui locking up.

So I manually renamed the interfaces in the xml file before restoring.

Good to know. I’ll have to take some screenshots to reconfigure after reset.

@moosport said in vlans stop working after using new hardware:

But it cannot ping devices on the same vlan. or the gateway.

Devices on the same network do not communicate through the gateway/pfSense.

Subnet mask correct?
