T1 Internet Connection

[drizzo1234]

I need to install a T1 Internet connection. I found that the 1841 Router has an internal CSU/DSU and 2 10/100 Ethernet Ports. Is this the best Router for my situation. 1 Ethernet for Outside to ISP and 1 Ethernet Inside for my Lan. Default Route will be to ISP router interface for Internet.

Their is also a Firewall option for IOS. Never worked with it. What do I need to Configure?

Hi

Cisco 1841 does brings in one T1 port with internal CSU/DSU,so you can directly connect the T1 link on that port.

you do have fastethernet ports which you can connect your local lan.

But not sure why you want to connect your isp link on the second fastetherent port here..

for firewall config info do refer this link which explains how a simple firewall feature can be configured in the 1800 series router..
