I need some help with a new project. I've never used Cisco ASA
before, and I don't know how to set this up.
I have Cisco 3800, with interface gigabitethernet 0/0 configured with
private IP for LAN, 0/1 configured with public IP.
ISP tells me that 0/1 (public IP) is to be plugged into one of the 4
ethernet ports in the ASA 5540. I assume I can configure one of these
ports for this, but I don't know how to do it. So my questions are,
1) Do I use a cross-over cable to connect router 0/1 to asa port?
2) How do I configure the port in the asa 5540? Do I assign it an
internal IP, and set up NAT in the firewall itself?
Thanks very much for any help.
