Cisco Firewall :: Managing ASA5510 Using ASDM Via Internal Interface
May 17, 2012
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 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
test@172.16.252.100's password:
Access denied

I'm on the ASDM of a 5510 and the logging with in the ASDM is currently set just right, but when I go into the console via SSH and use "term mon" I don't get this logging showing up. [code] As you can see I have set the ASDM and console to the same level. Currently in the ASDM I can see a user getting denied access to a device, but in the console view I dont get that, which I woudl like.

I have several machines behind this firewall. Each machine has it's own outside static IP and i've setup a NAT for each machine to their outside IP.Everything is working great, EXCEPT, from behind the firewall, I can't browse my own websites that I am hosting from behind the firewall. From a command prompt, the machines can resolve the url to the correct outside IP of our web server. Our DNS is externally hosted. I just can't get a website to open from behind the firewall. IE won't connect.
I did some logging, and I see from the firewall logs, the inside machine trying to hit the external ip. The log shows an INTERNAL IP on a random port trying to hit the external IP of our webserver on port 80. It says success! If I use packet tracer entering the same ips and ports, it also says success. And yet the site won't load on the inside machine?
The client machine I am testing from behind the firewall does also have it's own natted external ip. I'm not a command line/scripts guy. Looking at my ASDM Device Setup Interface GUI pagae, I see at the bottom both boxes are checked, one for enable traffic between different interfaces at the same security level, and the other enable traffic between hosts on same interface. My outside interface is security 0, my internal network interface security is 100.

I have a server that I need to open up some ports on to allow access to the new internal Sharepoint server we're setting up. I've been having some issues getting the ports open like once I put the commands in and save them that server suddenly stops allowing outbound traffic. After looking at a few things I noticed while I was looking at the config file that the ASDM location is showing 2 IP's, both are the same as the server I'm trying to open ports for one being the private IP and the other is the public IP I'm trying to use. Is this the reason I'm having problems when I try to open those ports to my server? Do I need to use both a different private and public IP for this server so I can get my ports to work? The programmers selected these IP's so if I need to change them I'll let them know in case they need to make changes for the Sharepoint setup. This is on an ASA 5505.

I have Cisco5510 running with ADSM 6.0 version, I was able to access it fine since few months but suddenly I am unable to login through that.Its prompting for username and password and loading it to 100% but not opening the GUI console.I feel this could be the JAVA version issue but with the same version of JAVA I am able run another ASA 5520 which is running with 6.4ASDM version.Request you to suggest the right JAVA version to run 5510 with ASDM 6.0 GUI console.

I have two ASA5510 with a peer to peer VPN configuration which is working pretty well.I'm trying to connect to my remote ASA (ASA2) with ASDM on my PC through the VPN on the local ASA (ASA1)I already connected the ASDM to ASA1 through the inside interface but I cant connect to the ASA2 the same way (over the VPN).
When I ping the ASA2 inside interface from my computer, I get the following events:

For years now we've had an ASA5510 running an old version of ASA/ASDM (7.0/5.0) and couldn't access ASDM through a modern system with a recent JRE, so we didn't bother with this.
However, we've recently upgraded ASA/ASDM for purposes of adding failover and want to be able to access ASDM through our site to site tunnel. The site to site tunnel gives us access to the VLAN that the firewall is the gateway for, but not access to the firewall itself.
This side of the network is the 10.1.55.0 subnet, and that side of the network is the 192.168.1.0 subnet. I can ping devices on the 192.168.1.0 subnet, but not the firewall, (not that I really need to) and devices can ping me back. I can access ASDM through RDP or ssh into a server on the 192.168.1.0 subnet, but not directly from the 10.1.55.0 subnet.
This is the current config relative to the 10.1.55.0 subnet:
access-list trust_nat0_outbound extended permit ip 192.168.0.0 255.255.0.0 10.1.55.0 255.255.255.0
access-list untrust_cryptomap_600 extended permit ip 192.168.0.0 255.255.0.0
[Code]....
As far as I'm aware, the tunnel comes into the firewall through the untrust (public) interface, because that is the destination of the tunnel on the 10.1.55.0 subnet side.
What am I missing here that would allow asdm access through the untrust interface for the 10.1.55.0 subnet?

I have an ASA5510 running 8.2 code and I have over 200 static nats from the outside to the inside interface and that is how I expose our systems to the Internet. If this inside interface fails we also have a bypass interface that also terminates on the internal network but I am not sure how the nats will behave given they are statically mapped to the inside.

Cisco ASA 5510 directly facing the internet on E0/0 (1 Public IP only) with internal LAN on E0/1. Exchange 2010 OWA working fine with ACL and NAT rules configured.Problem:
•1. Cannot publish internal web servers to outside, have tried PAT.
•2. Have multiple web servers to publish with all on one protocol (HTTP) to a single public IP which I don’t know if it’s possible on a ASA.
•3.When SSL VPN is configured with Local user database, connecting from Anyconnect client gives a certificate error. Upon viewing the certificate it points to the internal mail server.

Currently my ASA5510 has a 64MB internal flash. Does the ASA require a higher capacity flash for an IOS upgrade from 7.2(x) to 8.2(x)? The Cisco Release Notes does not state any internal flash requirement, but just wanted to double check.

I am using ASA5510 and i want to know if it is possible to redirect http traffic to an internal proxy software. I explain : PC from the LAN use a internal proxy in their IE browser but some other PC doesn't use it.They are directy connected to the Internet using the Public IP from the WAN interface ( via NAT). Can we redirected this HTTP Traffic from the WAN interface to the Proxy in the LAN ?
Http Traffic will be routed like that : PC -> WAN interface -> Proxy -> WAN interface -> Internet In fact,can we create a rule saying : All http traffic which doesn"t come from the IP Proxy must be redirected toward proxy.

I have a ASA5510 and I have a question about the speed the ports can handle, here is one port:
-interface Ethernet0/2
- speed 100
-shutdown
- no nameif
-no security-level
-no ip address
it's ethernet and not fastethernet so I figure it will only go to 10Mbps, but at the same time I can hard code the speed to 100.

We use filter rules on an ASA5510 firewall to direct clients to a web filtering server which generally works very well. However lately we're finding that despite having more web filtering licenses than users, the web filtering licenses are being consumed up, mainly because of a recent increase in the rollout of ipads, iphones, androids etc. We could deploy a proxy server in the wireless DMZ to make all the wireless devices appear to web filter as a single IP, and apply a single policy, but that brings it's own problems. My question is: Is there a way to hide them all behind the interface IP instead, so that all wireless devices appear to the web filter on the LAN as the wireless dmz interface IP rather than the wireless device IP?

Our ASA 5510 is running 8.0(5). We recently upgraded the license from base to security plus. By doing so the capacity of the the external port Ethernet0/0 and Ethernet0/1 should increase from the original FE to GE. But, we were still seeing 100 Mbps on our Ethernet0/0 interface. We figured that out that the provider switch is only supporting 100 Mbps which is a bottleneck for us.The provider will be upgrading there switches to 1 Gb switch.
We will have to swap the switch connections now from 100 Mbps to 1 Gb switch.What commands should we be familar ourself with?Though this will be doine in our maintenace window.All the transaltions/connections will be dropped in our production environment so we are kind of scared.

We have a Cisco ASA 5510 with:
-version: asa845-k8.bin
-ASDM: asdm-711-52.bin
Interface "Outside" is a PPPOE configuration.We currently have 36 site to site VPN connections up and running through the "Outside" interface. Now when we try to add, via ASDM, a new site to site VPN connection, we can not choose the "Outside" interface. The interface is just not available. All other interfaces are, bot those are inside interfaces.
I tried running ASDM on a different computer (thought that ASDM or java got corrupted perhaps), but the same problem appeared.Now when we "shutdown" the outside interface and "no shutdown" it again, the "Outside" interface is available again when you add a new site to site VPN profile.
Sidenote: if we check the current profile of a succesful running site to site VPN, it say's that it's using an inside interface. But that is, ofcourse, not possible.

I've been trying to configure the threat-detection scanning-threat shun feature on my ASA5510 running 8.4(2) for some days now. From searching the support community I can see that I'm not the only one having a problem with this feature. The problem I'm having is that after configuring scanning-threat shun, no outside attacking hosts are being shunned. I'm using nmap to simulate a scanning attack. [code]
Is this the expected behavior of scanning-threat shun? If so this feature is of very little use to me as blocking my inside LAN is not my goal. I'm trying to protect my LAN from Internet attack. I can add the except command and exempt my LAN, but this still doesn't fix the problem of outside hosts not being shunned.

I have two routers on my internal network.
10.10.199.106 is a Cisco ASA5510.
10.10.199.108 is a Sonicwall NSA 3500
The sonicwall handles our site to site VPN tunnels. The Cisco handles our client to site VPN connections.
I have a unit that points to 10.10.199.106 (Cisco) for internet access. All other clients on the network point to 10.10.199.108 (Sonicwall) for internet access.The device in question, a Synology NAS, is using 10.10.199.68 as it's IP address.
I'm trying to hit the web interface on the NAS from a remote site across our VPN tunnel. The IP scheme on the remote end of the VPN tunnel is 192.168.72.0/24.
Going through the VPN, I can hit every object on the network that uses .108 (Sonicwalll) as it's gateway. However, I cannot hit the unit that uses .106 (Cisco) as it's gateway.
I added a route statement (using ASDM) that routes all traffic destined to 192.168.72.0/24 to the Sonicwall so it can send it back down the VPN tunnel. If I'm understanding routing correctly, this should allow responses from NAS destined for 192.168.72.0/24 to go back down the VPN tunnel.

we have two Cisco ASA 5510 in failover configuration.We tried to change the public IP address on the Outside interface of the primary device but it didn't works. The new IP is not reachable from Internet nor pingable from device on the same LAN.The new IP address is in the same subnet of the old IP.
From the switch on which the ASA is connected and from another Cisco PIX we can see the ARP entry. In the analysis, on the old public IP address there was a VPN site-to-site and Webvpn defined.We tried also to shut/no shut the interface and reboot the device.

I have run out of public facing IP addresses and I need more. Assuming I have been issued 1.1.1.0/24 and my new/additional range/subnet issued is 2.2.2/0/24 - Can I carry on with the same configuration on my ASA5510 and just add static NAT for new services in the 2.2.2.0/24 range.
i.e.existing config
route 0.0.0.0 0.0.0.0 1.1.1.254 (upstream ISP)
Interface outside ip address 1.1.1.1 255.255.255.0
NAT 2.2.2.1 to 10.1.2.3
or, assume my ISP will deliver 2.2.2.1 to my outside interface (1.1.1.1.1/24) and if my NAT is in place it will get delivered to 10.1.2.3 inside.
or, put another way I dont need change my set-up as I just static route to my ISP!
my real public IP is a /27 can I use my broadcast address (its a legit public IP address)?
i.e 1.2.3.0/27 = 1.2.3.1 to 1.2.3.31
Outside interface = 1.2.3.1/27
Can I use 1.2.3.31 and NAT it to an internal server?
