Two physical interfaces acting as one

[Melim]

Hey
im setting up a HA scenario with one ISP conecting to both WAN Interfaces of PFSENSE (ETH01). I need to connect two LAN ports of each pfsense to each switch core (i have twoo swoitch core).
Should i use BRIDGE interfaces in order to make two physical interfaces on each PFSENSE, act as one, being able to connect to each switch to both firewalls? wjhat is the best for my scenario?

@Melim The “real” way to availability like that, is to have two switches that supports stacking.
Create a multi-chassis Link aggregation that runs LACP on the switch stack and a two interface LACP LAG in pfsense.
Connect one link to each switch and you have the best og by far fastest failover on link/switch chassis failure.
