I’m trying to configure an RB2011LS with v6.7 for NAT and DHCP service on an interface and eventually a hotspot with MAC address authentication. However, when I receive an IP from that interface, I get one from my upstream provider instead of a private IP in the DHCP pool. What do I need to do to remedy this? Establish a gateway on the upstream interface? And what is the proper NAT firewall rules I need for both the upstream interface and the subscriber interface?
