I have an ASA 5505 that I'm setting up. I need to give the inside interface a different subnet (192.168.200.1). I've been using the console port to make changes (db9/COM1) from the factory defaults. The problem is when I change the subnet I get locked out from using the ASDM via a LAN port and CAT5, and the DHCP server stops working though I configured it with the new subnet. I can access the firewall just fine via LAN port when it's at factory default, and DHCP works fine as well.
What should I do? thanks!
