This document shows you how to configure Network Address
Translation (NAT) and Static NAT on the RV160 and RV260.
Static NAT maps a one-to-one
translation of the private IP addresses to the public IP addresses. It creates
a fixed translation of private addresses to the public addresses. This means
that you would need an equal amount of public addresses as private addresses. This
is useful when a device needs to be accessible from outside the network.

Address Translation (NAT)
Step 1. Log in to the web-based utility of
your router. The default username and password is cisco/cisco.
Step 2. Navigate to Firewall > Network Address Translation.
Step 3. In the NAT table, check Enable
NAT to enable the NAT for those interfaces. NAT is enabled by
Step 4. Click Apply to save your settings.
Step 1. Navigate to Firewall > Static NAT. The Static NAT page opens.
Step 2. In the Static NAT Table, click the Plus icon to add a static NAT.
Step 3. Check the Enable check box to enable the static NAT. This is enabled by
Step 4. Enter the starting internal IP
address range that you will map to the public WAN. In this example, we will
only pick one private IP address to be mapped to a single public IP address. 192.168.2.100 is entered in the Private IP Range Begins field.
Note: You can enter in the starting IP address range of a Virtual
Local Area Network (VLAN) to map an entire VLAN to a single public IP address
or a VLAN to a range of public IP addresses.
Step 5. Enter the starting IP address of the WAN
IP address range provided by your ISP. You can map a VLAN to a single or a range
of addresses that was provided by the ISP. In this example, we will be entering
a single public IP address that the private IP address will map to.
Note: Do not include the
WAN IP address of the router in this range.
Step 6. In the Range Length field, enter the number of IP addresses in the
range. The range length must not exceed the number of valid IP addresses. To
map a single address, enter 1. The range is from 1-30.
Step 7. Select the type of service from the
drop-down list to apply for the static NAT. In this example, we will be using
the default value of HTTP.
Step 8. Select the interface that you want to
use from the drop-down list. We will be choosing WAN as our interface.
Step 9. Click Apply.
Step 10. (Optional) If you want to configure
or add a new service, click the Service
Step 11. (Optional) The Service Management page opens. In the Service Table, click the Plus icon to add a new service or select a
row and click the Pad and Pen to
configure the existing service. The following fields are:
Name – Name of the service of application
– Select the Layer 4 protocol that the service uses from the drop-down list.
Start/ICMP Type/ IP Protocol – Enter the port numbers reserved for this
service. The range is from 1-65535.
End – Last number of the port, reserved for this service. The range is from
Step 12 (Optional) Click Apply to make your changes.
You should have now successfully configured
NAT and Static NAT on the RV160 and RV260.
