At present I'm installing a ASA firewall between my 2811 router and the network.
The router at the moment has an internal ip address of 18.104.22.168 and has NAT rules set up. The 22.214.171.124 address is that of our exchange server. My question is this. If I change the internal interface of the router to 10.10.10.10 and the external interface of the ASA to 10.10.10.11 and the internal interface of the ASA has the 126.96.36.199 address, what do I do about the NAT rules?

You are just changing the interface of the router from 188.8.131.52 to 10.10.10.10, as far as the NAT statement is concern, you do not need to change anything. All you need to do on the router is to configure route for 184.108.40.206/24 subnet to point towards the ASA external ip address (10.10.10.11).
