Enterprise NAT Example
You can configure a PVC to allow IP address translations that create private
communication 'links' between workstations in remote offices and the Internet.
You can also use a PVC to communicate between a network manager's
workstation at a remote office (an NOC, for example), and a centrally located SLC
ConnectReach system. In Figure F-1 three PVCs are shown, all of which have
been configured with NAT on the SLC ConnectReach system at the Corporate
Headquarters.
Three Different FR PVCs configured for Enterprise NAT
PVC 1 is configured with the NAT setting PASS, so that the Network manager at
the NOC can pass packets directly through NAT to the SLC ConnectReach
system at the Corporate Headquarters office.
PVC 2 is configured with the NAT setting OUT, so that the PC on the Corporate
Headquarters Ethernet can have its IP address translated to a WAN (Internet
Access) address.
PVC 3 is configured with the NAT setting IN, so that the PC at the Remote Office
can have its IP address translated to a WAN (Internet Access) address.
NOTE:
This configuration does not address Firewall issues; if there is a Firewall,
the source (138.10.5.1 255.255.255.0) and destination (192.168.0.1
255.255.255.0) IP addresses for the management traffic must be permitted
by an IP filter.
