I'm trying to set up a pair of ASA 5510's in active/standby mode, and I've hit a bit of a problem. I've completed the following steps:
1. Out of the box, i've used the configure factory-default <ip-address> <subnet mask> to set an IP address on the management interface. I've plugged my laptop directly into the management port using a cross-over cable, and I can connect to the ASA using ASDM.
2. I then configured active/standby failover, and this appears to be working fine.
3. I then added a configuration via the CLI. This config is from a pair of PiX 515's that are being replaced. The config was generated using the PiX to ASA configuration converter available on cisco.com.
4. After adding this config, I can still access the ASA via ASDM, and everything appears to be fine. I saved the config to flash and powered down both ASA's.
5. Today, i've installed the ASA's on site. When I connect my laptop to the management interace using a cross-over cable, I can no longer connect using ASDM. when I try and use a web page with the address https://<ip-address>, I get the warning about using unsigned certificates, which I accept. I then get prompted for a username and password, which I have entered correctly. I then get a HTTP 404 - website not found message.
At first i thought it might be an access rule on the management interface, so I created a permit ip any any rule (for testing purposes) and applied it to the management interface, but this made no difference.
Can anyone point me in the right direction to fix this?
