Creating NAT Rule Policies: Examples

NAT Rule policies allow you the flexibility to control Network Address Translation based on matching combinations of Source IP address, Destination IP address, and Destination Services. Policy-based NAT allows you to deploy different types of NAT simultaneously.

Unless otherwise stated, the examples in this section use the following IP addresses as examples to demonstrate the NAT policy creation and activation. You can use these examples to create NAT Rule policies for your network, substituting your IP addresses for the examples shown here:

• 192.168.10.0/24 IP subnet on interface X0
• 67.115.118.64/27 IP subnet on interface X1
• 192.168.30.0/24 IP subnet on interface X3
• X0 IP address is 192.168.10.1
• X1 IP address is 67.115.118.68
• Web server’s “private” address at 192.168.30.200
• Web server’s “public” address at 67.115.118.70
• Public IP range addresses of 67.115.118.71 – 67.115.118.74
