I would like to use Peplink or MAX series as a NAT box for industrial projects. Peplink router has rugged design and support static or range NAT.
NAT Mappings works vey well. But I need an additional feature calling BiDirectional NAT for End units have not default gateway or End units whoose default gw can not be changed.
So Source NAT should be arrangable on LAN interface for me?
What do you think?
Another solution, learn default gw settings of End Units with packet capture and use Gratious ARP or Proxy ARP to catch packets destined to default gw by MAX router
