2 switches between Router (on a stick) and Modem

[returntrip]

Please, need some help with verifying my setup:

My pfSense router is in the basement whilst my modem is on the upper floor. I have connected the two by means of 2 TP-Link switches (TL-SG108E/TL-SG105E) and VLANs connected in the following manner:

Router <> Switch <> Switch <> ISP

Config Router Connected to pfSense:

Port 7 is used for the Router
Port 8 is used for the trunk with the switch on the upper floor
Port 1-6 for client devices

VLAN Assignment:

PVID:

Config Router Connected to Modem:

VLAN Assignment:

PVID:

Port 4 is used for the modem
Port 5 is used for the trunk with the switch in the basement
Port 1-3 for client devices

The setup works fine but would like some sanity check re VLAN config being correct and potential issues on the WAN side.

Thanks in advance!

Don't use those TP-Link switches with VLANs. They don't handle VLANs properly.

That should be OK but like @jknott said those switches cannot be trusted to do the right thing.

Thanks! The switches are HW V4 and the problems related to VLAN 1 were fixed in V3. Is there any other issue they might have?
