hello all I ask an aid to solve a problem that I have a customer that I recentlyacquired.
From this account is already configured a ASA 5505.
I state that I have 0 knowledge of cisco firewalls and these days I havedocumented on the internet and reading its manual.
The firewall is working fine and there is also configured on a VPN to connectfrom the outside owners.
I tried to connect to ASA via https from a PC LAN but nothing. By reading anddocumenting I downloaded putty and I'm connected to the firewall via console.
Later I see the configuration that has been made.
Comparing the more info I found on the internet I see that the http server is down and you have not configured access. Provvedo and I enable him to exacta PC LAN.
Try again to connect, this time it shows the page's security certificate is invalidor I clicc not recommended, so I go out well but soon after the error can not find the page, with the explorer. I try with safari and it turns out the error http 404 or440? (if I remember correctly). I go to see if there is a bin with putty dell'asdm in flash memory and it turns out there but I can not find the file. (sorry I'm writingcarelessly, but as you know better than me, this is seen by typing certain commands)
A point I stopped because I do not want to create trouble. I would open certainports to an internal ip and then being allowed outside access from any PC on that port through public ip.
Can you help me by giving me the commands to be written in putty or I can lend a hand to pick up on the ASDM (so that the GUI definitely am I doing?)
Thanks to all who respond
what type of vpn is configured on ASA box ?
what version of OS is running on ASA ?
Better you post full configuration here along with requirment someone for sure can tell/modify configuration which you can use.
here the configuration:
I darkened the references of the customer name and password. In this configuration lacks the activation of a single ip http server to the internal LAN.
I can not connect to http. but I'm fine even if you give me the string to be writtenusing putty. thanks guys

From what I can understand you want to be able to access the ASA from the internal network using the GUI (ASDM)
For that you will need:
1- Have the HTTP server running on the ASA
2- Have an ASDM image on the flash of your ASA ( You can get one from cisco.com)
3- Set the ASDM image so the users can connect to the ASA
3-Decide on the HTTP server configuration who can access the ASA using HTTPS
1- http server enable
2- on the sh flash you should see an asdm image ( Show flash)
3- Set the ASDM image into your ASA ( asdm image flash:xxxxxx.img
4-http 0 0 inside ( anyone can access the HTTP service on the Inside LAN, you can be as restrictive as you want)
If this does not fixs it provide me the following:
sh run http
sh run asdm
sh run aaa

I copy you on Monday the results of the commands you told me because all the steps you mentioned I have done. The asdm image is set but in my opinion can not find the file in flash and so must be recharged. But since they do not know, I stopped and asked for info to you before creating damage.
Sure just let me know!
Please rate all the helpful posts
asdm image is there, but not charged, in my opinion. However, an alternative would be enough for me to help me to write commands with putty ...
The asdm version set in the config is 5.2.3
asdm image disk0:/asdm-523.bin
The software version you are running is 8.0.4, which only supports version 6.0.x or higher. ASDM 5.2.3 will not work.
So upgrade your asdm image to the latest which is 6.4.7 via TFTP
change that in the config by the command:
asdm image flash:/asdm-647.bin
enable the http server
http server enable
Also allow the network subnet which is allowed to access the asdm by the command:
http x.x.x.x y.y.y.y (x.x.x.x is the network and y.y.y.y is the subnet mask)
None of this is done is your config. Once you do this you should be all set without any issues.
I hope you should not have any questions after this.
I can not download the update file dell'asdm because I am not a dealer and I have no cisco certification. I did not sell me the firewall to the customer, I've found there. No one can pass the updated version of asdm?
