Our
small company has recently been assigned the network number
206.222.222.0 by ARIN. Previously the company was using a private IP
address on the internal network. Now that the company is going to be
connected to the Internet, we need to either go to each and every
workstation and configure it with a new IP address, or to use some
kind of IP address translation at the router. For security reasons
our company does not want the computers to be directly on the
Internet, using real IP addresses. Since our company only has a
limited number of computers, we have decided to use static network
address translation. It is our job to configure the ISDN connection
and implement the address translation. |

our company does not want the computers to be directly on the

number of computers it would be too time consuming to enter all of
the static address translations into the router. Our alternative is
dynamic network address translation. It is our job to configure the
ISDN connection and implement the address translation. |

Our
quickly growing company has the network number 206.222.222.0, which
was assigned by ARIN. Previously the company was using dynamic
address translation over an ISDN line however the company has just
upgraded the line to Frame Relay. The company has been growing and
has outgrown the number of valid IP addresses. The company is not
able to get another class C network from ARIN, so we need to find
another solution which will allow all of our employees Internet
access without over running the available valid IP addresses. We
have researched NAT and found that if set up properly we can
translate many internal IP addresses into one valid IP address. This
is called Overloading Network Address Translation. It is our job to
configure the Frame Relay connection and implement the proper
address translation. |

Configure a Frame Relay connection between our WebHeads router in
Orlando and the ISP's router in Houston, and configure TCP Load
Distribution on the WebHeads router. |

Configure an ISDN connection between Bread company router and the
Butter company router, and configure it so that the two networks
which have the same IP addresses can communicate together. To
accomplish the communication we will configure dynamic overlapping
network address translation. |
