Options

• ABuild Mo-1 NAT translation for users that need access
• BRe-IP overlapping address space in the acquired company

Explanation

When networks have overlapping IP address space, NAT (Network Address Translation) is used to resolve the conflict. Option D - using a pool of NAT IP addresses - is the most efficient scalable solution. A NAT pool assigns a unique translated address to each session or user, allowing multiple users in the acquired company to simultaneously access corporate applications without address collisions. Option A (1-to-1 static NAT) requires manual configuration for every individual user, which is operationally intensive. Option B (re-IPing the acquired network) is extremely disruptive and time-consuming. Option C (NAT overload/PAT with a single IP) is problematic when the acquired company's users need to be individually reachable or when return traffic routing is needed from corporate apps back to specific users - a pool provides better scalability and manageability.
