Why cant I access asdm via web browser?

I can access the ASA 5505 via Putty, but not the ASDM. I cant figure out why. when i launch a browser and try to connect, i get "Page cannot be displayed". I have tried http/s, i added a seperate port#... everything i can think of. Running config attached.

oh, i am trying to connect using the local 172.22.4.1:8081 ip.

we also have 2 other ASA's that i manage via asdm. all 3 are now the same version, 8.2.5 and 6.4.5 yet when i try to connect to this one i get an error that the version is unknown and unsupported. very strange.

Hi,

I can only see in the configuration that you have allowed the HTTP/ASDM management through the "outside" interface but not through the "inside" interface

http server enable 8081

http XX.233.79.232 255.255.255.255 outside

http XXX.9.24.213 255.255.255.255 outside

So you should probably add

http 172.22.4.0 255.255.255.0 inside

Hi,

I think you need to add the command

management-access inside

Unless it was already in the configuration.

This is the only way to allow management connections to reach an internal interface of the ASA through a VPN connections. On the basis of your configuration that network is located behind a L2L VPN connection.

Naturally you will also need a "http" command for that network. I guess you will need to use the interface "outside" in that statements end. Or if it doesnt work, try "inside".
