Cisco Firewall :: Disable Admin / ASDM Access Only On Public Interface Of 5510
Oct 12, 2011
how to totaly disable Admin/ASDM access on our public interface of our 5510. I don't want to change IPSec or SSL access to the outside interface. Just totaly disable access to Admin/ASDM from the outside without halting all other access.

I copied a Cisco 5510 startup-config to an identical Cisco 5510.After copying through tftp, I executed a reload. Everything looks good. Line by line compare results are the same.The problem is I can no longer use ASDM or ssh to interface with Cisco 5510.

Our ASA 5510 was configured with a public interface, a DMZ interface, and a private interface. I have a remote access VPN using AnyConnect client and LDAP authentication for Active Directory. We are changing ISP (groan!), which means all new public IP addresses. The new circuit is installed, so I have a second public interface (same security level as the first public interface, wholly different IP address range) enabled on the ASA. I hope to transition whatever I can, which means get the VPN access through either public interface. Can I just enable client access on the second public interface at the Anyconnect Connection Profiles tab in ASDM? That seems too simple. Can they share the one address pool?

getting my additional IP addresses working on my ASA 5510. I have a /29 allocation and outbound access and inbound access to my internal www server is working fine through the default outside interface. However, I now need to setup a second IP address that maps internally to a different web server. When I setup a new network object with automatic NAT translation to the new IP address, it does not work. If I setup the same scenario using the outside interface, it works fine. What is the proper way to setup additional IP address on my ASA v8.4?

Recently powered down device (transformer overhaul) and when it booted back up, unable to access with ASDM, SSH...can access directly using HyperTerm, but have only limited commands...will not accept known user/password credentials. When I issue 'show flash' I can see that there are upgrade_startup_errors.log files, but cannot access them.

I do have one other question first. What's the effect of the crypto key zeroize rsa command, and then crypto key generate rsa modulus 1024 while I'm SSH'd to the ASA? Can I do it? Or do i need to be consoled in or connected a different way?
ASA 5510:
ASA Version 8.4(1)
asdm image disk0:/asdm-641.bin
asdm history enable
http server enable
http 10.1.1.83 255.255.255.255 inside
http 10.1.1.82 255.255.255.255 inside
Shouldn't that right there be enough to access ASDM from either host .82 or .83? Because I cannot. But if I add http 0.0.0.0 0.0.0.0 inside, then I of course can.

I have a cisco ASA 5510 that I have set up currently to access via ASDM through the Inside interface. When I VPN in using our older VPN server I can connect to it fine. I recently set up the ASA to also be a VPN server which will eventually replace the older server for our HQ. I noticed that when I'm VPN using the ASA as the VPN server, I can only ASDM to the public which I prefer not to allow. Access to the inside doesn't seem to work this way. What configurations if any would be causing this. I'm assuming it's some thing I need to adjust in the VPN configuration.

So I've run into a problem on my ASA5510, post-upgrade I can no longer connect to the inside interface from across our L2L VPN. I've tried both ASDM and SSH and the connections fail. I see in the logs that the attempt is being made, but it will eventually time out. There have been no problems with this type of connection with any previous upgrades, just this particular upgrade, I went from 8.4(1) to 8.4(2). I don't see much in the release notes or anything in a pre/post config diff that jumps out as a cause to this behavior. The only thing I did see in the release notes "CSCtg50770 Mngt-access (ASDM,SSH) to inside intf of 5580 fails over RA VPN session" which sounds like it could be my problem, but that was in the "Fixed in 8.4(2)" section and says it's for a 5580, maybe the fix for the 5580 broke it on a 5510??? I hope not and that I'm simply missing some new setting that I need to enable for this type of connection as this device is in a remote office.

I created some acess-lists, and you can assign a logging level to this access-list. Now this ACL has a lot of hits, so i want to see whats happening. Only the log I then see is completely empty. I cannot figure out how to get some info in that log.
I think there is some global logging setting i probably need to enable in order to get anything logged at all, but i cannot figure out which.

We need to deploy a Cisco ASA 5510 behind the Internet facing router for Remote Access VPN (RAVPN). We bought the block of 16 IPs (in a different subnet) which is routed through the main router (69.x.x.x)and configured the outside interface of ASA with a public IP 64.x.x.x and subnet mask 255.255.255.240. Below is the network structure.
But, we can't access the ASA by it's public IP.
DSL Modem → RV082 router → Switch → LAN
(69.x.x.x) ↑ (192.168.0.0)
Cisco ASA 5510
(outside: 64.x.x.x, inside: 192.168.0.172)

I have an ASA 5510. (ASA 8.0(4) ASDM 6.1(3) I have 2 internet connections (only 1 is currently active) Currently all internet and VPN traffic go over 1 interface. What I want , is to move general internet onto the new internet connection but keep VPN traffic on the old internet connection. I can get the internet working but as soon as i do the VPNs go down. VPNs are site to site vpns.

Hardware Version : V3
Firmware Version : 1.4.0 Build 111130 Rel.56405n
ISP :
Just installed my new 8960 and it's working fine. However, I'd like to disable admin access from wireless, and only have that available via the LAN. I can't find anything that looks like it'll do that in any of the setup pages, is it possible? All previous wireless routers I've had have been able to do this.

we have a server that has an outside IP and an inside IP. It's inside ip is 192.168.222.30/24 and it's outside IP is 199.204.50.2/29. The connection to this server from the outside is perfectly fine, but access from inside users to the NAT'd IP which is 199.204.50.2/29 is having issues, however, access to the inside IP works fine (this part makes sense)Will It be a must to set the inside DNS A record to the inside IP and not the outside IP, or can users on the inside interface access the NAT'd IP which is assigned to the server
LAN(192.168.222.0/24)<=====>InsideASAOutside<=====>(Server with NAT IP 192.168.222.30/24, it's also physicall assigned to this server).This is an ASA 5510 with 8.4.

My internal network consists of Catalyst 3750 switches segmented into different VLANs. There is a default route on the layer 3 Catalyst switch sending all unknown traffice to the inside Internet of the ASA 5510. However, I'd like to have a separate VLAN for wifi guest access and send all of that traffic through one of the DMZ interfaces on the ASA 5510. I don't think you can have separate default routes based on VLANs on the 3750 switches so my only option is to make the ip address of the DMZ port the default gateway for all hosts on the wifi guest VLAN.
The problem I have is that I have a couple servers behind the inside interface that have services available to the public Internet via a NAT address on the outside interface. I want the guests on the wifi VLAN to have the ability to access the servers on the inside interface using the public address as well, but have not been able to come up with a solution yet.
Here is my config that pertains to this setup:
interface Ethernet0/0description Outside Interfacenameif Outsidesecurity-level 0ip address 76.47.10.x 255.255.255.224 rip send version 1rip receive version 1!interface Ethernet0/1description Inside Interfacenameif Insidesecurity-level 100ip address 192.168.17.1 255.255.255.0 rip send version 1rip receive version 1!interface Ethernet0/3description Wifi Guest Accessnameif DMZ2security-level 50ip address 192.168.60.1 255.255.255.0

I've tried the following commands below but no dice.
same-security-traffic permit intra-interface
static (inside, inside) 76.47.10.x 192.168.17.88 netmask 255.255.255.255

I would just like to to open UDP port 123 in the ASA 5510 Firewall so that our Primary Domain Controller could use this port to sync time with an external time source. We have already added an access rule for this port under the firewall configuration in ASDM 6.4 and this port was also allowed in the inbound and outbound rule of the PDC's Firewall but it seems that it was still blocked.

I have an ASA 5510 in a live environment. Up til a short while ago I could access this via the ASDM and ssh. However I can no longer connect to it via eithier. When I access It via SSH I get a disclaimer saying the following
*** You have entered a restricted zone! Authorized access only!!! Disconnect immediately if you are not authorized user! ***
It then cuts me off.
When I try to access the ASDM I get the following
The firewall is running all its services without a problem and I can ping the device without any issues. Also none of the config (to my knpowledge has been changed). I set up a console session and http server enable is still there with
http 192.168.200.0 255.255.255.0 inside

I'm encountering what I think is an issue on logging system on FW ASA 5520 - Asa Version 8.4(2), ASDM version 6.4(5). When I disabled the logging inside a rule from ASDM, or from console with the "log disable" option inside ACL, If I check in ASDM logging real time window I continue to see all the entry related to disabled rules. This is a correct behaviour about ASA logging ? How I can "hide" the entry related to disabled rules (this is what I need for troubleshooting purposes) ?

I try to SSH and get access denied.
I try to ASDM and get "Unable to launch device manager from 172.16.252.100"
I think I am missing something. Software is 8.4(5) and running in Transparent Mode.
Inside/Outside are in bridge-group 1. No BVI is configured as we will be using Management0/0 for access.
login as: test

We are running a Cisco ASA 5510 in our district. We have been using it for about a year and a half after an upgrade from our PIX. I have been using the CLI to manage it but I wanted to start using the ASDM. I installed the ASDM Launcher last Friday but could not access it. I have enable the http server on the ASA, assigned an IP to the interface, and granted my machine's IP inside access. On Friday I was unable to launch the ASDM. I then downgraded Java. I came in this morning and was able to connect through the launcher. However I could not make any changes as it would give me an error message and often popped up with "lost connection" type messages. I then closed the ASDM but could not reconnect after that. When I try to connect through the launcher I receive the message "Unable to launch ASDM from 172.16.5.1: Connection reset". When I try https://172.16.5.1/admin/ from a browser I simply receive "page cannot be displayed". I'm not sure why I can't connect.

Running Asa5510, 8.2.5, with asdm 6.4.5 and I am looking for a graph in asdm that will show me what protocols and internal ip addresses uses the most traffic. Maybe a bit like "Top 10 protected servers under SYN attach". My reason for this is of cause I see a very high traffic pattern from one of my interface during the day and need to identify what is using bandwidth, protocol and source address.
I could use Net Flow feature in the Asa, but it´s not "real time" and forces me to setup a net flow collector. Can 8.2.5 not give me this information with built-in graph/tools?

I am currently managing an ASA5510 using ASDM through the management port but I would like to manage the ASA through the internal port.
My concern is that I thought I remembered reading someplace that if you setup an internal port for management that it can't be used for anything else. Is this correct?
I only configured one internal port and it is the path to my LAN. I would hate to configure the port for management only to find that I disconnected my firewall from my internal network in the process. Can I use my one and only configured internal port for both ASA management and route from my LAN thru the ASA firewall?
I currently have the management port set to 192.168.1.1 and my internal interface is 10.1.1.1. If I open ASDM and connect thru the management port and select Configuration/Device Management/Management Access/ASDM/HTTPS/Telnet/SSH
select "ADD"
select access type "ASDM/HTTPS"
select interface "internal"
IP Address "10.1.1.0"
Mask "255.255.255.0"
Will that give me access to ASA management thru my internal network but cripple my network access to the ASA?

I was able to connect to my ASA 5510 with a browser, install ASDM, and configure my ASA 5510 with my Windows 7 laptop. Since I needed the laptop for another task, I am now trying to connect using a Linux laptop to do the same, but without success.
I can ssh into the firewall using the management port (192.168.1.1) from the Linux command line. However, I cannot connect using a browswer (192.168.1.1) to install ASDM.

I was unable to access the web admin on my WRT160n v3 w/ latest firmware this morning. Reset config to defaults & was able to get in. Enabled HTTPS access & disabled HTTP access & was right back where I started; reset to defaults again & left both boxes checked. Can access via HTTP, but HTTPS requests get refused/reset.
The reason I needed access was that when I booted up my laptop this morning, my wireless card wasn't picking up an IP address via WIFI, only worked via ethernet, so I need to see what was going on there — several reboots of the router didn't fix, nor has it fixed the HTTPS access problem described above.

i have an issue with ASA 5510.
I connect to the device - https:/interface
I see the options such as download launcher etc.
But.. whenever I click on this I get stuck
Internet Explorer gives "page not found"
Or at the foot of the page it says "unable to download statup_lr"
Firefox says cannot connect
It is running 6.2.5.53
I can connect if I go to a PC where I have already downloaded the ASDM launcher (from many years ago)
Tried Win 2003, 2008 and Vista, and Windows 7
Tried downgrading to Java 6 r 7. Can I download the launcher from the Cisco website rather than the device? If so where?
