Appendix B: Network IP Topology
Private Network With Near-end NAT Traversal
The following command associates the public address with the Inter-Tel CS-5200/5400/5600
private address. This creates the "NATed" address. The ISP must be known to send packets for
this public IP to the Inter-Tel CS-5200/5400/5600.
ip nat inside source static 192.168.1.2 208.13.17.2
!
The following commands set up the dynamic NAT configuration to use a pool of public
addresses. This is not specific to this example, but it is included here to contrast static vs.
dynamic NAT.
