Help needed on vlan config & setup

subject configuring Multi-WAN setup over poe switch ???

I need some help

im getting ready to setup a Multi-WAN setup for failover isp with

my cudy 4g outdoor poe modem

but my current network/rack setup leads to a mass re-config issue because my setup an power strips (cyber power ups backups) im at my limit for power plugs an i only have run for to pieces of gear if powered by poe an that i have its were

i planed to plug-in my cudy 4g outdoor poe modem but after reading the Firewalla Feature Guide: for Multi-WAN iv hit a dilemma my current network config of voip,nas,network printer, an switches i dont have a free port direct on my FWG only two poe’s on my switch

what i want to know is is ther a way to setup a 2nd wan for isp fail-over with my cudy but with the poe port on my switch ?

the poe adapter that came with the cudy doesn’t pass the vendor or ip info of the cudy correctly to the FWG it only will if i dont use its poe adapter an plug direct to either the FWG or poe switch , but this defeats the intended outdoor use.

note

my switch is 48v output i do have a adapter that works with the cudy an does pass the vendor & ip info for the FWG to read

someone told me that quote

“You can usually set up something like this with VLAN’s on a managed switch. It looks like you are setting up a port on the Firewalla Gold as a second WAN to the cudy 4g outdoor poe modem. And you want to put a powered managed switch in-between the Gold and the cudy 4g outdoor poe modem. This can be accomplished by setting up your LAN devices on one VLAN that the managed switch knows about, and the Gold WAN port to another VLAN on the managed switch using two of the managed switch ports (as shown in your diagram).”

“The Firewalla Gold doesn’t have to know about the VLANs as you can configure ports on the managed switch to add the VLAN tag on the traffic coming from the Gold WAN port and strip the VLAN tag going out the second managed port to the cudy 4g outdoor poe modem (and the same for the LAN traffic, but a different VLAN tag so the WAN and LAN traffic are segmented from each other in the managed switch). This presumes the cudy 4g outdoor poe modem doesn’t require VLAN tag use itself.”

What i want to know is 2 things 1 is the person right an 2 whats the step by step for doing this
as i havent had the best time doing vlans myself with out a guide

this is the managed poe switch i have that i plan to use

Sodola 8 Port 2.5G Web Managed PoE Switch 120W|1X 10G SFP+&4 PoE Network Switch

plus adapter

48v to 24-Volt Converter, 48V Power Over Ethernet Adapter Convert

YES, via the means your already referred to
but not generally recommended as WAN failover is tricky and you just added a huge point of failure for your redundant WAN
an inline POE injector would be ideal here, just run the LAN cable from the router to a POE injector closer to your modem and an open outlet/UPS.

never heard of that, sounds like a bad injector

Sounds like you need a PDU

PDU whats that

my network rack has two CyberPower CP1500PFCRM2U PFC Sinewave UPS System, 1500VA/1000W, 8 Outlets, AVR, Short Depth 2U Rackmount

an both wall outlets an all the plugs on both ups’s are full
to run the cudy right now iv unplugged the cooling for the rack to use the cudys inline poe an right when the spectrum goes does down we just switch the wifi connect to the cudy for just the laptop

fyi the only other wall outlet is on the other-side of the room an ther no more space in my rack
“huge point of failure for your redundant WAN” ill take that just so i can tie in the back wan without a massive redo of my whole rack an server layout

just swapping out one of my switches for the Managed-PoE an adapter seems like that best move

but can i get a answer to the

configuring ports on the managed switch to add the VLAN tag on the traffic coming from the Gold WAN port and strip the VLAN tag going out the second managed port for the cudy ?

an should i leave the cudy in dhcp mode or switch it to static mode before or after plugging it is a wan source ?

Power Distribution Unit. In its simplest form it’s a rack mounted power strip. Smarter versions offer monitoring of power consumption and/or remote control over individual outlets.

Fitting to your Cyberpower could be the fancy Cyberpower PDU 41001.
