The documentation for this feature is a bit lacking. We have a Balance 305 with around 300 devices behind it on multiple VLANs. We have 2 WAN ports. One has a single static IP and the other has a /24 of public assigned to us (WAN 1).
What am really need to accomplish is to pass through public IP space from the /24 to one of the VLANs and NAT the rest of them. Some of the VLANs are designed for internal use only (no access from the Internet but they do access out to the Internet).
We have done 1:1 NAT mapping but it does not work well with VOIP and VPNs. So, ideally, I use IP Forward and assign real public static IPs to certain MAC addresses behind the Peplink. I have tried setting this up on a test router but can not make it work. Perhaps it is not possible to do what I am after. When I change a WAN port to IP Forwarding from NAT, I don’t see any other settings become available to me. What do I do next? Is there a set of examples for this feature?
