HI. Ill be doing an install of a T1 to a 2811, then to a ASA5505. Usually Ive done 5505's behind dsl or cable and let the 5505 NAT. But Im assuming Ill be getting a /30 address from the circuit provider, giving me 1 address. This is probably a simple question, but it seems like the 2811 will NAT, the inside interface will be private, then the ASA will provide DHCP for the LAN.
Im just not sure how to config the ASA with all interfaces being private. if someone has a sample config that would be great! Thank you.
