Hello EE. I have a question on router configuration. We have a T1 circuit provided to us by an ISP. The circuit did not come with a managed router. I had to get a DSU/CSU T1 card for my cisco 1841 router and configured it with the wan IP info provided to me by the ISP. Everything is working fine. My question is can I still make use of the Lan block of IPs provided to us by the ISP without another router? I have 2 fastethernet ports but one is in use to connect to the inside network.
