How to configure Cisco 2811 to work with Adtran equipment from ISP

Hello everyone,

My mothers real estate business currently uses a Linksys E1500 home router and she would like to upgrade to something alot better and more secure as they are going to be starting online banking etc. They currently have an Adtran 924 with a cable going from ETH0/1 going to the ETH1 port on an Adtran 838. From the Adtran 838 ETH2 i have my ethernet cable going to my linksys router then to our switches

Will I be able to replace the E1500 with a Cisco 2811? It currently has two interface cards (T1 DSU/CSU) and (CTRLR T1/E1) and then a fa0/0 and fa0/1. If so, what port will I plug the incoming internet connection into and how do I need to configure it to output the internet connection to my switches?

Will I just need to configure

Will I just need to configure one ethernet port with the public address and the other with my private address and then configure NAT?
