ASA 5505 Remote Access to ASDM

[marcbilyou]

How do I enable remote access to ASDM from outside of the network on the ASA 5505?  This would be used for remote access to the firewall at a site that is not utilizing VPN.

Thanks in advance !

If I get your question correct, you can enable http on the outside interface;

http server enable

http 255.255.255.255 outside

Hope that helps,

Thanks,

what if you are hosting another site using https?

[varrao]

It is for https connection only.

You enter the following URL to access it:

https://

which is on port 443.

Thanks,

Hi, 

I

What if i have a Web-Server behind my ASA and only 1 outside public ip? If i use static nat-port 80 and http 255.255.255.255 outside to enable http will it work?

That's no problem. Under the covers ASDM is actually opening a URL that resides in the ASA configuration in memory. The ASA is smart enough to distinguish that from https traffic destined for your server.

ASDM uses http(s) for communications to the ASA. So, you need to add the command:

http source_IP_address mask source_interface
Example:
hostname(config)# http 192.168.1.2 255.255.255.255 outside
in your configuration. That is further described here.
