Static Nat (One To One) - Samsung Ubigate iBG3026 Configuration Manual

Static NAT (one to one)

In static(one-to-one) NAT type, for each IP address in the corporate network,
one NAT IP address will be used. For example, for the three IP addresses from
10.1.1.1 to 10.1.1.3, there is a set of three NAT IP address from
50.1.1.1 to 50.1.1.3. In case of one-to-one NAT, only IP address translation
takes place, that is, if a packet travels from 10.1.1.1 to yahoo.com, the
Firewall only substitutes the source address in the IP header with the NAT IP
address. The source port will be the same as the original.
The static NAT configuration shown in Figure 23.6 includes:
Private network address: 10.1.1.1-10.1.1.3
Public(NAT) IP address range: 50.1.1.1-50.1.1.3
To create NAT pool with type static, specify the IP address and the ending
NAT IP address. Add a policy with source IP address range and attach NAT
pool to the policy.
