Using public range of IPs

L4 Transporter

I have a bit of a silly question to ask but my mind is drawing a blank on this.  If you have a connection from the ISP, say the static IP range is router is and the PA FW will be  Simple enough but what if they also give you a usable range of IPs to use, say   To use these IPs , would you need to assign the external interface an additional IP on subnet, or could you just create NAT rules that NAT traffic to IPs in that range?

Thank you both!

you don't even need to add routes (unless the IP range lives on a different interface than where goes out of)


When you create NAT rules that use this new subnet, the firewall will perform proxy arp for the IP addresses (or entire subnet) you configure in the NAT rule. Adding a 'destination interface' in the NAT rule will help the firewall identify which interface these proxy-ARP packets need to go out of
