In this video we implement NAT and SNAT on an F5 device. The video comprises of three parts:
1. Implement NAT: NAT is one-to-one mapping of public and private IP addresses. You do not need a virtual server or a pool in this scenario. Traffic coming from outside to the public IP of server is translated to private IP of the server by the F5 appliance.
2. SNAT Automap: SNAT is source address translation where in you translate the source IP address. Connection is originated from client on internet so that becomes the source IP address and it is translated to the IP address of F5 device on the internal side where our servers our located. Priority for SNAT automap is first floating IP address then local IP address of the inside interface.
3. SNAT Pool: Connection is originated from client on internet so that becomes the source IP address and it is translated to the IP address defined by the administrator in the SNAT pool. IP should be from the internal network which in our case is 192.168.1.0/24.
NAT is used in case of one-to-one mapping. SNAT is used in case of asymmetric routing and/or if we want to hide the IP address of client originating the request.
