I am Terribly Sorry for not being around, my apologies in advance, was out of town (wife running a marathon) and have not been anywhere near a computer in days....

To give some clarification and some background let me lay out what i will be doing over the next few days and maybe this will help me help you help me (??)................. *smile*

i have a network that i will be reconfiguring remotely that is a small workgroup that needs outside access to hit databases here where i am (California) from where they are (Washington DC). the network is as follows:

Covad DSL line coming into thier own hardware router with 4 ethernet ports on the back (router/switch combination). I have a Cisco 1605R that is currently NOT in use, but sitting over there as part of the system ready for me to get setup. the Cisco plugs into a HP Switch that feeds 4 standard X86 based PC's, there is a Livingstion Terminal Server that feeds about 10 Wyse terminals, and there is a SUN Ultra5 that houses a small Informix database that the users update with flat file data.

My job is going to be as follows:

1.) flash the firmware on the router to get it up to date (its running firmware that is 5 years old at least, and prob doesnt support NAT at this time)

2.) reconfigure the Cisco Router with the new ip pool from Covad and configure the proper access to NAT'd internal Nodes (192.168.x.x ect..)

3.) telnet in and reconfigure the HP Switch, Livingston Terminal Server, and Ultra5 with the new ips

4.) after i finish the final change, i will be in essence locked out until i call someone at that office, and have them move the cable from the old Qwest router over to the Covad router and then into the system i just re-ip'd and ill be damned if it all comes up on the first try.

Some of the issues i will face:
1.) I will have to use the Covad router in order to keep them (Covad) happy, IE, if i dont use it, and there is a problem with the line, they will blame me first and the line second. if i have their equipment in use, then they HAVE to come out in order to close the ticket, and since im 3K miles away, having their techs available will be a must.

2.) will i be able to have the Covad dsl modem/router there inline and then connect the cisco router to it? yes it seems redundant to me too, but if i HAVE to use the Covad equip, can i not just leave the Covad stuff set WIDE OPEN, and do all my filtering in the Cisco?

3.) finding and understanding a good NAT discussion (i read some of what was on Cisco's site "NAT for first timers" or somethign, and while it was helpful, there was very little to do with an acutal "walkthough" (am i expecting too much here?)

Thank you all for your help, i am working on this for the next two days, so i will be paying close attention to any questions and help that anyone has.



Again, thank you for all your time, and if needed, i can certainly create a .jpg that would be a Visio diagram or any other supporting info that anyone would need.
