=================================
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
=====
+--------------+
+------------+ GEb/0/0 | |
| Tester +-------------->+ vCGN/vPE-f |
| +<--------------+ VM in UCS |
+------------+ GE13/0/0 | |
+--------------+
Configure Interfaces and add routes in vPE-f
=============================================
set int ip address GigabitEthernetb/0/0 10.4.5.2/24
set int state GigabitEthernetb/0/0 up
set int ip address GigabitEthernet13/0/0 20.4.5.2/24
set int state GigabitEthernet13/0/0 up
ip route add 4.4.4.0/24 via GigabitEthernet13/0/0
ip route add 1.2.3.0/24 via GigabitEthernetb/0/0 show ip fib
Configure vCGN NAT44 for UDP/TCP/ICMP
=======================================
set vcgn inside GigabitEthernetb/0/0 outside GigabitEthernet13/0/0
set vcgn port limit 65535 set vcgn dynamic port start 5641
set vcgn map 10.1.1.0 - 10.1.1.31 set vcgn tcp timeout active 65535 init 65535
set vcgn udp timeout active 65535 init 65535 set vcgn icmp timeout 65535
Set ARP entries for CGN to Tester
