Choose the NAT mode based on your network needs: 1. Static NAT for one-to-one mapping, 2. Dynamic NAT for many-to-many mapping, and 3. PAT (Port Address Translation) for many-to-one mapping. PAT is commonly used for home and small business networks since it allows multiple devices to share a single public IP address, making efficient use of limited IP resources.

FAQs & Answers

  1. What is Static NAT used for? Static NAT is used for one-to-one addressing, allowing a specific private IP to always be mapped to a single public IP.
  2. What is the difference between Dynamic NAT and PAT? Dynamic NAT allows multiple private IP addresses to be mapped to multiple public IPs, while PAT maps many private IPs to a single public IP using unique ports.
  3. When should I use PAT (Port Address Translation)? PAT is ideal for home and small business networks where many devices need internet access but only one public IP address is available.
  4. How does NAT improve security? NAT improves security by obscuring internal IP addresses from the external network, making direct access to internal resources more difficult.
