Management Access Rules in ASA/ASDM

[J W]

Can someone explain what the Magement Acess Rules does in the ASA? I read up on it a bit (or tried to), but I am unsure how to use it, or what it is good for. In my mind, it should restrict who you want to grant to-the-box access to (SSH to console, https to ASDM, etc), but it doesn't work that way it seems.

If I want to allow someone to SSH to the ASA, I have to enter the command ssh <IP> <Mask> Outisde. If I add a rule to allow or deny an IP using the management access rules, that seems to get ignored.

I am not exactly sure which rules you are talking about when you say management access rules?  Management access rules are the ssh and http commands you issue when configuring management access.  Do you mean you are trying to deny management traffic using an ACL or control plane policing?

The thing is that the ssh and http commands will override all other ACLs.  This is so that if you misconfigure something then you will still have access to the device instead of being locked out.

In ASDM the section I am talking about is:

Configuration> Device Management> Management Access Rules

[Marius Gunnerud]

The ASDM management access rules section configures control-plane policing for the device.  The ssh and http commands, as I mentioned earlier, override all other access control configuration.  this includes interface ACLs, VPN ACLs, and control plane policing ACLs.  Again the reason is to prevent a lockout in the case of misconfiguration

hi jared,

yes, that's the section in ASDM where you configure which protocol (telnet/SSH) and which source IP to allow access "to" the ASA.

you'll need these commands to allow SSH (via CLI).

hostname

domain name

crypto key generate rsa modulus

ssh

aaa authentication ssh console LOCAL

Working with a customer who wants the "splash screen" disabled.

Meaning, when the public IP is placed in a browser, he is seeing prompts for login / password.

I have changed the default for ASDM/HTTP to something other than 443 to see if this would help.

Really don't want to disable the ASDM access from our public IP to the customers public IP of the firewall.

Thanks.
