Basically you need to add the new subnet (or IP) to allow ASDM access before you change the inside IP address :)

thanks Pete! that was it. <br />
I had to disable DHCP first, before I changed the interface subnet. <br />
<br />
Let the games begin!! I'm sure you'll see more questions from me....

Hello <br />
<br />
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. <br />
<br />
What should I do? thanks!<br />

Configuring inside interface with different IP/Subnet

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).
