We are getting a T1 line installed and I need some help with the router settings. The ISP gave me these settings and I want to make sure I put them in the right locations (I hid part of the addresses for security reasons). Thank you in advance for your help!!!!

## ISP provided me with this info

Serial IP Information: 00.000.000.3 – 00.000.000.6
Serial IP Range 00.000.000.0 – 00.000.000.7 (8 Addresses)
CPE (Customer Premise Equipment) WAN Interface: 00.000.000.53
Customer Network: 00.000.000.52
Customer Net Mask 255.255.255.252
Customer Gateway: 00.000.000.54
Subnet Mask: 255.255.255.248
Primary DNS: 00.000.00.3
Secondary DNS: 00.000.00.4


## My Router/Firewall Network Settings Screen

Are they providing a router to go in front of the sonicwall? They listed a serial connection this would require a CSU/DSU installed in a router.

I agree with wingates about the serial IP and CSU/DSU. However, below is how the other information matches up...

Serial IP Information: 00.000.000.3 – 00.000.000.6
Serial IP Range 00.000.000.0 – 00.000.000.7 (8 Addresses)
CPE (Customer Premise Equipment)
Customer Network: 00.000.000.52
Customer Net Mask 255.255.255.252





 -- LAN Settings --
*note: this is all your internal private LAN info.
SonicWALL LAN IP Address:  
LAN Subnet Mask:
Network Gateway Subnet Mask:
Add LAN Subnet:
         
 -- WAN/DMZ Settings --

** WAN Gateway (Router) Address: = WAN Interface: 00.000.000.53
** SonicWALL WAN IP (NAT Public) Address: = Customer Gateway: 00.000.000.54
WAN/DMZ Subnet Mask: = Subnet Mask: 255.255.255.248

** these two ip's may be reversed. this is how I have normally seen it. but....

-- DNS Settings --

DNS Server 1  =  Primary DNS: 00.000.00.3
DNS Server 2  = Secondary DNS: 00.000.00.4

rliu1112,
Thank you for clarifying those settings!!! We will be making the change in a couple of days and I will let you know if all goes well.

Wingatesl,
They are going to install a Cisco IAD before the firewall. I sent an email requesting the model number and to verify if it has a CSU/DSU.

The IAD will definitely take care of the serial issue. Pretty much follow rliu1112's IPs above and you will be on your way!

That's good to hear. Do they usually configure that top information for you when they install it?

Our installer forgot to order a necessary part needed for the install. Now we have to wait until next week.

Everything is installed but we are unable to access the internet. Maybe we don’t have the cables connected right. Can someone provide me with instructions on how to connect these devices? Please specify if we need to use a crossover cable.
