+ =================================
+ CARRIER GRADE NAT - NAT44 README
+ =================================
+
+What is implemented:
+====================
+* NAT44 UDP, TCP, ICMP protocols
+* Show and config commands for various parameters for the same
+* NF9 logging is implemented but is not tested
+
+What is not implemented:
+=========================
+* TCP MSS
+* TCP refresh direction
+* Static port forwarding
+* Syslog support
+* Destination based logging or session logging
+* None of the ALGs
+* Performance optimization
+* Binary APIs, suitable for configuring the feature from netconf/restconf/yang
+* Support for VLANs
+
+Setup
