NAT
The RL1000GW routing package supports Static and Dynamic settings of Network Address
Translation.
Dynamic NAT settings allow LAN members to initiate sessions with targets located at the WAN.
The NAT router (RL1000GW) will use its WAN IP interface as the new source ip of the session
request, hiding the original private IP of the initiating LAN device. The NAT router can use a single
WAN ip interface to traverse multiple private IP addresses of its lan, thus limiting the required
public ip addresses to a single one.
Static NAT settings, direct incoming WAN traffic to a particular target LAN client. As the WAN
stations usually will not have a route to the private LAN, but only to the WAN ip address of the
router, the static Nat settings are mandatory to allow them to initiate sessions towards LAN
targets.
The NAT router serves both a routing function and security layer, allowing provisioning of WAN
traffic access to the LAN.
Networking
Following picture will suggest NAT networking results per configuration option of dynamic/ static
NAT set at the RL1000GW.

Looking at picture ‘NAT networking 1’, PC communication towards the server is dependent on the
NAT configuration set at the RL1000GW NAT router.
