How to configure a Linksys E2000 router

A client has asked me to connect a CISCO 1800 router provided by his communications company to the router in his office and configure it with settings they’ve given him.   His office router is a Linksys E2000.  I need to know what fields I have to update with the proper values in  the E2000.  

Thanks,  
Al

Here is what the communications company gave us:

 Cisco 1800
Here is an IPCONFIG ALL from the office computer:  

IPconfig
The office computer is a Dell Optiplex 790.  Here is the configuration:

Yes, that is correct.
Restart also office PC and check ip configuration (ipconfig /all). If also your office PC gets DNS servers 66.109.38.250 and 66.109.38.251 then everything is ok. Else put that DNS server ip addresses also in DHCP server settings - static DNS1 and DNS2.

about the only needed change is on the basic setup address change from 192.168.1.1 to 192.168.0.1


cloud -> cisco router -> e200

This is assuming that the ipconfig you gave was with that computer connected to the cisco router.

On basic setup page change from DHCP to static IP option. You will get additional fields for external interface and there enter IP address, subnet mask and gateway address you got from ISP. At DHCP server options enter two DNS server addresses.

Is there any easy way to back up the router configuration and then restore it quickly, if there are any problems?

So I take the communications company configuration,

Router Config
And change the following settings in the router:

New Settings
“Automatic Configuration DHCP” becomes “Static IP”
Internet IP Address becomes 66.152.111.122
Subnet Mask becomes 255.255.255.252
Default Gateway becomes 66.152.111.121
DNS 1 becomes 66.109.38.250
DNS 2 becomes 66.109.38.251

Is that correct?

Thanks,
Al
