Source NAT (many-to-one)
The following figure shows an example of SNAT in which many different “inside” addresses are dynamically translated to a single “outside” address. In this example, all hosts on the 10.0.0.0/24 subnet show the same source address externally.
To configure NAT in this way, perform the following steps in configuration mode.
Create SNAT rule 10.
Apply this rule to packets coming from the 10.0.0.0/24 network and egressing through the eht0 interface.
Use 220.127.116.11 as the source address in outgoing packets. Make sure that the translation address is an address defined on the outbound interface if it is part of the connected subnet on that interface. This ensures that the vRouter replies to ARP requests from remote devices for the translation address.
Commit the change.
