Layer 3 Subinterfaces VM-Series Firewalls VLAN 4095

L4 Transporter

When it comes to vm series firewalls, Layer 3 subinterfaces, trunks and port groups, are there any downsides/catches/cautions to setting the ESXI port group to use vlan 4095 (trunk), and then simply utilize layer 3 subinterfaces on the vmseries firewalls with 1 NIC?  Article noted below, using just like a normal trunk if I understand correctly? Seems to work as expected as long as I have the TAG number on the firewalls interface.  Wondering if anyone has had problematic experiences with a setup like this?  I don't think we've ever used a trunk interface marked as 4095 going to anything.   Plenty of switching trunks and cisco routers on a stick, but never from an ESXI host trunking to a virtualized palo alto with layer 3 interfaces.   Should work as expected?

it kinda depends on the 'size' of your vm. The larger vm's (700) spread the load over their internal CPU cores based on the source interface, which could be a limiting factor if you put everything on  a single interface. other than that there shouldn't be any issues
