What is a 1:1 NAT, and the requirements?
A 1:1 NAT requires at least one additional static IP configured on your Meter Security Appliance’s WAN port (2 IPs total). See Hardware > Security Appliances > Ports. A 1:1 NAT is typically used to access a server on the local network via the public IP address. For example, if you have a secondary public IP of 12.12.11.11 and set up a 1:1 NAT with this IP to an internal host of 10.103.0.7 - ALL traffic destined for 12.12.11.11 will be forwarded to 10.103.0.7. This will allow 10.103.0.7 to act as if it were on the public internet.A note on security with port forwards
By default, creating a 1:1 NAT will open up the internal host to ALL outside communication. To allow only certain hosts or ports, ACL rules must be made on the WAN port to ALLOW only certain traffic and DENY all else on the public IP used in the 1:1 NAT. Learn more about creating ACLs here: Firewall > ACLs.How to add a 1:1 NAT
To configure a 1:1 NAT, log into the Meter Dashboard and navigate to Firewall > 1:1 NAT > Click on “Add 1:1 NAT rule”. This will expand the menu on the right-hand side of the screen.
