Assign given MAC Address to Virtual IP

[frhack]

I'm trying to use pfsense as firewall in OVH infrastructure.

OVH gives a MAC address for every public IP.

I need to specify the given MAC addresses to the virtual ip in OVH in order to establish DMZ networking (OVH rule).

Is there a way to assign the given MAC in pfsense Virtual IP ?

From the web GUI is not possible, maybe from shell ?

thanks

I found a workaround as follows.

(I' m in VMWARE esxi)

for every public IP:

• create a virtual NIC attached to WAN network
• create in pfsense a new WAN interface with the assigned MAC address WAN_xxx_xxx_xxx_xxx (where xxx_xxx_xxx_xxx is the public IP)

At the end I will have n WAN Interfaces, one every public IP (for example 16 or 32 …)

...is there any drawback?
