pfSense WAN lagg group

trinitech

Hi,

I am setting up an new xcp-ng cluster in a quarter rack.
The datacenter is providing only 1 cat5 drop to my unit.
What I would like to do is minimise the risk of downtime and have everything in HA with the single cat5 drop as the single point of failure.
I have
1x PowerEdge C6220 with 4x node
2x Dell PowerConnect 5548
2x pfSense (6 ports each)
1x Dell Powervault MD3200i

The plan was to create 1x vlan99 of 7 port on each switch.
SWITCH1:
port1 - cat5 feed in
port2 - pfSense1
port3 - pfSense2
port4 - pfSense1
port5 - pfSense2
port6 - conection to vlan99 to switch2
port7 - conection to vlan99 to switch2

SWITCH2:
port1 - conection to vlan99 to switch1
port2 - conection to vlan99 to switch1
port3 - pfSense1
port4 - pfSense2
port5 - pfSense1
port6 - pfSense2

The idea here is if a port on the switch fails, the wan remain online via the second port.
Both PowerConnect are stack via HDMI.

My question is:

Is this feasible/possible
is there a better way to do it?

In pfSense I when I set 2 ports has lagg group with LACP and set it to be the wan.
In the switch, I set all the port connected to the pfSense lagg to be lagg lacp.
But then I lose the gateway and access to the internet.

Does anyone know why I lose the connection to the gateway? Do I need to tell pfSense that it needs to be looking for vlan99?

Thank you in advance
