Cisco AAA/Identity/Nac :: ASA 5520 / Dynamic Access Policy VPN And Management Access
Jun 8, 2011
ASA 5520 to get it to authenticate VPN users against and Active Directory environment plus allow management access as well. I created a Dynamic Access Policy on the ASA stating that if you are a member of the Active Directory group "Managment" the continue. I chagned the DefaultAccessPolicy to "Terminate". So with that, VPN users cannot connect because they are not a member of that group, but the access to manage the ASA is allowed because of that policy.Is there a way through using Dynamic Access Policies that I can allow management access (SSH, ASDM, etc) by matching to a group membership and will allow normal users to VPN in successfully but not allow them access to managing the ASA?

I am new to v5.3, and I am not good at VPN.I just have my consultant to configure this correctly just today. Currently, there is only one rule for the access policy (Single Result Selection). That rule is to use Active Directory as the source for the authentication. And by default will deny any other access which is not found in the rule.Now... I just got an order that I need to setup a new user who will need to access to our network by using Cisco IPSec VPN (the software one). But that user is not setup in our Active Directory, and we do not want him to access our domain anyway. He only needs to access non-domain resourse...such as airconditioning controller by IP. So I am thinking to setup his account by using "internal identtity". If I do this way, what do I need to do to setup another access policy? May you give me some steps with little more details? OR... if it is not the way I should do...what else can I do to achieve this goal? Also, he said he could provide his static IP trying to access from. I have a ASA 5520.

we have a nat exemption rule for 10.0.0.0/8 to w.x.y.z followed by some static nat rules and then dynamic policy nat rule for 10.0.0.0/8 to w.x.y.z natting to IP a.b.c.d.When I do a packet trace from 10.10.10.10 to w.x.y.z, it shows the packet first matching against the nat exemption rule, and then immediately afterwards it matches the dynamic policy NAT rule. The static nat rules are being successfully bypassed (which is what I want), but why does the dynamic policy nat rule apply if an exempt rule has been hit already? An actual test between the IPs above reflects the result of the packet tracer as well (IP a.b.c.d is seen on server w.x.y.z).We are running the following software on an ASA5520.

how to map my command shells that I created to the access policies under Default Device Admin/Authorization. All I get an option for is Shell Profile but not commands. See attached doc.ACS 4.2 was easy.. I would just create a command set and apply to a group.

I am configuring an ASA 5520 for VPN access. Authorization & Authentication use an LDAP server. I have the tunneling configured successfully, and I can access internal resources. What I want to do now is to restrict access to a specific AD Group membership. In the absence of that group membership, a user should not be allowed access to the VPN.
My test VPN client software is Cisco Systems VPN Client Version 5.0.05.0290. The group authentication is configured into a Connection Entry that identifies the Tunnel Group. I think I worded that correctly.
The Software Version on the ASA is 8.3(1).
My current challenge is getting the VPN to stop letting every access request through regardless of group membership.
[URL]
The configuration (AAA LDAP, group policy, and tunnel group) is below.
aaa-server LDAP protocol ldapaaa-server LDAP (inside) host x.x.y.12 server-port 636 ldap-base-dn dc=domain,dc=com ldap-scope subtree ldap-naming-attribute sAMAccountName ldap-login-password ******** ldap-login-dn

I am prepping new ASA 5525-X's for a client that has multiple S2S VPN's. On some of the VPN connections, I need to do a policy nat to translate some of their subnets to a single IP address before it goes over the S2S VPN. However, when I try to use a subnet, I keep getting the following error:
Subnet cannot be used as mapped source in dynamic nat policy.
This works fine on their old ASA's which are running 8.2 code. I figured out I can use a network range, but cannot go over 65535 (or whatever it is) addresses in that range. This is very annoying when they have multiple networks they want to allow over the S2S VPN. Is there anyway around this or am I stuck creating a network range for each subnet?

I have devices on Inside interface of ASA that need to get to Internet to get ntp. Hence I want to set up dynamic pat (interface overload) which 8.3 style would be
-object network obj_NTP-DEV
-host 192.168.1.250
-nat (INSIDE,INTERNET) dynamic interface
But I need to limit nat to only Internet destined traffic on ntp port not all ports for traffic from 192.168.1.250.I'm not using this nat set up to control outbound access - I also have incoming RA VPN tunnels to the box and traffic from these sources need to be able to get to 192.168.1.250 and the above simple set up would break that access as all traffic involving 192.168.1.250 would get nat'd
Reading the doco I've sent myself round in a loops trying to figure how you are meant to do such a " Dynamic Policy NAT (overload)" call it what you will config in 8.3

We have a Service Policy rule setup on our 5510 for SMTP traffic.
Problem is, this week someone sent a larger email 20+mb to dozens of recipeints and the outside interface was hitting 10mb, which is not what I would have expected with this rule in place, so I'm questioning the configuration. We know it was email because I disabled the server that receices our outbound mail to apply a signature and the traffic dropped immediately.

We just upgraded to ASA 8.4.4.1 and the latest CSD image, 3.6.6203. We currently have a DAP set up to scan one group policy for a secific AV but wanted to start implementing this for all group policies and including several different flavors of AV (so anyone could connect from anywhere as long as a pre-approved AV is installed). We are going to allow about 20 different versions of different AV's and I've tested a couple already and they're successful.
My issue right now is trying to allow (or deny) AV that is installed on an Android tablet (and potentially Apple devices). The tablet has avast Mobile Security installed, and even if I select Vendor: Alwil as a whole, it still does not recognize it and denies the user. I have tested on a PC and it works fine. Is there something that I am missing or are mobile AV programs not included in the DAP policies? Is this going to be considered for future versions of CSD or ASA or are we going to continue to consider Android and Apple devices "secure" and not in need of an AV?

I have a new DIR-655 and have successfully added three access policies. I am trying to add a fourth, and have gone through the wizard making all the necessary entries. After saving, I get back to the list of existing policies, but the one I just added does not appear.

Would there be some reason why I cannot change the Access Restriction to Allow? I also can't add anything into the Website Blocking by URL Address or the Website Blocking by Keyword. I can't type anything in the fields. I've tried rebooting, other browsers and even other computers but nothing seems to work.

I am tasked with configuring a 2504 wireless controller. Is it possible to assign an SSID to an interface that has dynamic ap management enabled?
Scenario:
Location1:
1) 10.0.0.0/24
2)192.168.0.0/24 DMZ
Location 2:
1) 10.0.5.0
Both locations are routable using network 1 at each location. However, I need to configure several access points and send them to location 2. These access points will communicate with the controller at location 1 on network 1. Two SSIDs will need to be on network 1 at location 1. The other SSID will be on Network 2 at location 1. This network is not routable.

I am trying to create an IAP for a single computer based on it's MAC address. I want to block certain keywords and websites 24/7. When I setup the IAP as number 1, I add the MAC address of the computer in question. I then Select Allow and choose Everyday and 24 Hours. I type in the forbidden domains and click add after each one. I type in the keywords and click add after each one. After I click on Save, all of my computers on the network lose internet access.

I have an RV110W running firmware version 1.0.1.6 and I am trying to figure out how to enable website blocking in the Internet Access Policy screen. The Add Row button is grayed out in that section, as are the associated checkboxes.
Is there something else one needs to do to enable this feature?
If I set a name etc. at the top, and click save, it tells me "You must at least set a website blocking or PCs rule," so it is not the case that one has to save some information before continuing!

I need to configure an existing 2600 router to use dynamic NAT for access to the web and ALSO I have (5) fixed IP addresses for use with an email server, a web server, and (3) future servers. I do not know the concept of how to set this up. I'm currently using dynamic NAT for the web and this seems OK but I dont know how to map my fixed servers. I assume this is done with static NAT. Do I need to add sub interfaces on the S0/0 T1 interface for each of these fixed IPs? Then do I somehow do static NAT on these fixed IPs to their respective servers?

I have a remote ASA5505 running 8.4(3) with a working site 2 site VPN tunnel to my main office. (The main office is running an ASA 5510 with OS 8.4.3 as well). The encryption domain is all private IP on main site vs. 172.16.10.0/23 on remote site.
Relevant config of the remote ASA:
interface Vlan1
nameif inside
security-level 100
[Code].....
I can manage the ASA on the outside interface (outside of the site 2 site VPN) using the TACACS credentials I can also ping my management station from the ASA using the inside interface, but as stated, the other way around does not work. I have not yet tested if management from the local 172.16.10.0/23 subnet works, but I will try this next.

I have a SG300 switch working in layer 3 mode. I created 3 VLANS and the intervlan communication is working fine. I want to know how to block acces to switch managment from the Vlans. One of the vlan is allowed to access the switch but not the others vlans. What is the best way to implement this? with ACL or with Managment Access Method, creating an access profile?

I have my wlc 4400 configured with a secure wlan and a guest wlan. The guest wlan is switching traffic at the wlc to a separate guest-wlan interface. When a guest is associated and authenticated, they can access the management console of the wlc which is in a different subnet. As I understand, the wlc does not route traffic. So how could this be happening? the guest subnet and the subnet the wlc management interface is in are different and separated by a firewall. I have also tried applying access lists in the wlc to each interface without luck. How can i stop the wlc from providing access to guest wlan users?

I just managed to get hold of an old second hand WAP4410N from a friend who got it for work but never really had the time to get it working. I powered it up and performed a 30/30/30 reset to get rid of anything he may have done to it but now I'm struggling to get to the management page. The power light is steady and the ethernet light shows activity but I can't seem to find it on any IPs. I've tried both hooking it into a router and setting up a laptop with an IP of 192.168.1.2, subnet mask of 255.255.255.0 and gateway of 192.168.1.245 and I still have no luck. I'll fiddle with it more tomorrow but it'll probably just involve messing around with more settings and resetting it again, nothing of any real structure. Is there any way of forcing a new firmware onto it over the MAC address or something, for example?

After I've upgraded software to the v7.3 and applied AP-SSO it made imposible to access the controller's gui via Service-port. So we tried to access it by management-port, but there is some problem too. It is not working from another subnets. But default gateway on management vlan is set correctly and I even tried to turn of all acl's on switch. WLC is only accessible from the same network. But at the same time wlc is replying on ping fine.All other protocols cannot connect to the controller.

We have an RVS-4000 router that we use as an Internet gateway on our school network. I am trying to set up an Internet Access Policy to block some specific websites by URL using a domain name. I set up the policy, and added a PC to the list using the mac address, and the blocking did not work. I went back to the list and added the IP address of the same PC, the policy still did not work to block the domain. I rebooted the router, cleared the Internet Temporary files and history on the PC, and the policy still does not work. It acts like it is going to block access to the website because it takes a long time, but it will eventually connect.
