NAT Translations
Firewall
Network Address Translation (NAT) is a technique to modify network address information within IP
packet headers in transit. This enables mapping one IP address to another to protect wireless
controller managed network address credentials. With typical deployments, NAT is used as an IP
masquerading technique to hide private IP addresses behind a single, public facing, IP address.
NAT can provide a profile outbound Internet access to wired and wireless hosts connected to an
access point. Many-to-one NAT is the most common NAT technique for outbound Internet access.
Many-to-one NAT allows an access point to translate one or more internal private IP addresses to a
single, public facing, IP address assigned to a 10/100/1000 Ethernet port or 3G card.
To view the Firewall’s NAT translations:
1. Select the Statistics menu from the Web UI.
2. Select System from the navigation pane (on the left-hand side of the screen). Expand a RF
Domain and select one of its connected access points.
3. Select Firewall and expand the menu to reveal its sub menu items.
4. Select NAT Translations.
FIGURE 78 Access Point - Firewall Nat Translation screen
The NAT Translations screen displays the following:
Hit Count
Displays the number of times each WLAN ACL has been triggered.
Refresh
Select the Refresh button to update the screen’s statistics counters to their latest values.
Protocol
Lists the NAT translation IP protocol as either TCP, UDP or ICMP.
Forward Source IP
Displays the source IP address for the forward NAT flow.
