Can someone tell me if it is possible to have both options, where one of the LANs is NATed and another LAN is not NAT’ing, but rather using the IP addresses in the LAN. Does NAT-Mappings still apply a NAT even when the WAN interface is configured using “IP Forwarding”?
The WAN can only be in one state, either IP Forwarding or NAT, however a vLAN can use NAT via a virtual network mapping.
Maybe a network diagram would help us work out a config that would fit?
