The document proposes two plans to deploy a Link Controller in the network. Plan 1 involves placing the Link Controller behind the switch, moving NAT from the firewall to the Link Controller. Plan 2 places the Link Controller before the switch, also moving NAT to the Link Controller. It requests information including NAT rules, public IPs, internal/external Link Controller IPs if either plan is implemented.
