We've got a bloc of 8 static IPs from our ISP (BT in the UK). Our Meraki MX400 is setup with PPPoE and gets a (dynamic!) address based on a username / password. We want to be able to use our static IPs - to route to other servers behind the MX400. I was under the impression this could be achieved using No-NAT (We have v15.10 on the MX)? Any configuration help appreciated!
You can do double NAT where you configure 1:1 NAT and then use the LAN and WAN IP to be the same. The only thing that you need to confirm with your carrier, if they will route those 8 IP through the PPPoE connection.
I think @Fady pointed out the most likely solution to your problem. In many cases you can 1:1 NAT. Go to Security Appliance>Firewall and in the 1:1 NAT section just put the public IP and point it to the LAN IP of the device you want to have that IP and you'll likely be good to go.
