First of all let me tell you that I'm totally new with Cisco firewalls. I have experience for Watchguard only.
I need to configure firewall to use static IP for outside network. With wizard I can configure ASA to use DHCP for outside network and everything goes fine but when I try to configure ASA to use static IP I can't connect to outside world anymore.
There is a router from ISP between ASA and internet and it uses static IP 220.127.116.11. I need to configure ASA to use IP 18.104.22.168 for outside interface.
Can you tell me the steps to do this? Can it be done in ASDM or do I need console connetion? Should I create static route between router and firewall or how do I tell firewall the IP of the router?
