Proxy ARP add a whole range

[Jannus]

Hi there,

We have recently placed a Pfsense firewall in our datacenter.
From the isp we got a /25 range.

Is there any possibility we can add the subnet in one strike, and use seperate ip addresses for specific port forwarding (NO 1:1 nat).

Or do we have to add ip addresses one by one?

Thanks in advance,
