ASA 5505 after setting firewall transparent option by mistake.

[jompolo01]

Hi, 

Unfortunately we've changed firewall transparent option by mistake, after disable this option and restore factory-default, it doesn't work properly. Any idea about what the problem will be?

we are not able either to access asdm.

Thanks in advance and regards

There's no ASDM image specified in the configuration.

Do a "dir" to see your image version available on disk and then specify it thus in the config:

asdm image disk0:/asdm-xxx.bin

(substituting your version for "xxx")

[jompolo01]

unfortunately it didn't fix the issue.

It looks like after modifying the config someone overwrite the new one and now if we do a default restore it is not configuring the same thing.

[Marvin Rhoads]

What happens when you try to access ASDM?

Please share the output of the following:

show firewall
show ver | i AES
show run asdm
dir

Please find attached :

ciscoasa# show firewall
Firewall mode: Router
ciscoasa# show ver | i AES
Encryption-3DES-AES : Enabled perpetual
ciscoasa# show run asdm
no asdm history enable
ciscoasa# dir

You don't seem to have added the image into the config as I recommended earlier.

Please do so as follows:

conf t
asdm image disk0:/asdm-752.bin
end
wr mem
