What is cisco pix_access_list_elements

Hello

I have a firewall pix 515e with 7 (0) x verion of the image. When I run sh run, I cud see 1000 lines of ACL, and when I have see access list I could see that there are 30000 access list items.
What is the diff between access to list items and the acl lines?
How to reduce the elements of the acl?

Thank you
Rajesh

Hello

I guess you set up ACLs that use the object 'group' in the configuration. Essentially, this means that the ACL configuration you is shorter than the actual full ACL that uses the ASA.

Take for example these 2 configurations

Example 1

access list TEST-1 ip allow a whole

ASA (config) # sh - TEST-1 access list

access list TEST-1; 1 items; hash name: 0x5f8608f2

allowed for line of TEST-1 access list 1 extended ip any a (hitcnt = 0) 0xa45bef40

As you can see from the above, we have only a single configuration line. As there is not any "object-group" used for the two services or IP address/network it means it contains only this single rule. There is thus a simple 'element'

Example 2

object-group network TEST

network-object host 1.1.1.1

network-object host 1.1.1.2

network-object host 1.1.1.3

network-object host 1.1.1.4

TEST-2 access-list of ip enable any object-group TEST

ASA (config) # sh - TEST-2 access list

access list TEST-2; 4 elements; hash name: 0xc7ff2230

allowed for line of TEST-2 access-list 1 ip scope all TEST 0xabbab304 object-group

allowed for line of TEST-2 access-list 1 ip scope any host 1.1.1.1 (hitcnt = 0) 0x8af4a0e1

allowed for line of TEST-2 access-list 1 ip scope any host 1.1.1.2 (hitcnt = 0) 0xbd31ccb2

allowed for line of TEST-2 access-list 1 ip scope any host 1.1.1.3 (hitcnt = 0) 0x32e99e16

allowed for line of TEST-2 access-list 1 ip scope any host 1.1.1.4 (hitcnt = 0) 0xcb4432ae

As you can see in the example above, we first create an object 'group' that contains 4 IP addresses and then we use this "object-group" as destination address of the unique configuration ACL line. This means that the current rule is that we allow all 4 of these traffic destination IP addresses in the configuration and it therefore 4 'elements'

If configuration of ACL may include you large quantities of used "object-group" . You will have to see if all of them are needed. For example, if you use "object-group service" type of object "group" in your configuratins with several ports defined then this will easily generate a lot of additional ACL 'elements '.

Hope this helps

    Paul,

    AnyConnect lets connect you using IKEv2/IPsec and SSLVPN for IOS network head.

    There are countless examples of configuration.

    Alternatively, some clients of IKEv1/IPsec 3rd party exists and are able to connect, however is those who are not TAC (Cisco) supported. You can check the feature called ezvpn

  • I need VPN gateway to gateway with NAT for several subnets, RV082

    I have a pair of RV082 routers and I would like to configure a gateway to gateway VPN tunnel, as described in a book, "How to configure a VPN tunnel that routes all traffic to the remote gateway," (name of file Small_business_router_tunnel_Branch_to_Main.doc).  I followed this recipe book and found that my while the main office has internet connectivity, the branch subnet is not an internet connection.

    Routing behaves as advertised, where all traffic goes to the seat.  However, the 192.168.1.0 subnet in the branch receives no internet connectivity.  I read in other posts that the main router will provide only NAT for the local subnet, not the Management Office subnet.  Is it possible to configure the RV082 router to provide NAT for all subnets?

    If this is not the case, what product Cisco will provide connectivity VPN Tunnel as well as the NAT for all subnets?  The RV082 can be used as part of the final solution or are my RV082s a wasted expense?

  • PoE on RV016

    I have looked on all technical and hunted around, don't seem to understand if the RV016 or RV082 support PoE.  Anyone know for sure one way or the other?  Assuming this isn't, what product Cisco would be preferable to inject PoE on a small business network.  I have 1 RV016 and am looking to deploy an RV082 and WAP4410N, the 4410 is the only device on my network that would need PoE, I prefer not having to buy a switch or a Hub dedicated just for a single device.  Thanks in advance.

    wjdenihan,

    Unfortunately, none of our Business Cisco routers small PoE power, or can be activated using PoE. If you're looking to connect a PoE device to one of our routers, yes you can use a power injector to do this, out bound to the device. for example WAP4410n you can use the WAPPOE12. You can find this information on the WAP4410n Access Point user's Guide

  • NAT on 8.3 and VPN tunnel with overlapping addresses

    Hi all

    I was looking at this document from Cisco and I think I understand how to convert the nat policy than the version 8.3 and later, but I was wondering what is happening to the acl crypto, you are always using the same as the older versions? As you know the 8.3 then NAT requires to use the original instead of the address translated to the ACL, but I don't know if this applies to crypto ACL as well. Pointers?

    Example from the link:

     access-list new extended permit ip 192.168.2.0 255.255.255.0 192.168.3.0 255.255.255.0 !--- This access list (new) is used with the crypto map (outside_map) !--- in order to determine which traffic should be encrypted !--- and sent across the tunnel. access-list policy-nat extended permit ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0 !--- The policy-nat ACL is used with the static !--- command in order to match the VPN traffic for translation. 
     static (inside,outside) 192.168.2.0 access-list policy-nat !--- It is a Policy NAT statement. !--- The static command with the access list (policy-nat), !--- which matches the VPN traffic and translates the source (192.168.1.0) to !--- 192.168.2.0 for outbound VPN traffic.
     crypto map outside_map 20 match address new !--- Define which traffic should be sent to the IPsec peer with the !--- access list (new).

    Thank you

    Hi rc001g0241,

    I posted your question for clarity sake along.

    "what happens to the crypto acl, always use you even as older versions?"

    As you can see, Cisco doc you posted shows that you need to target for crypto engine is what happens after the nat policy has succeeded, illustrated here: "address match map crypto outside_map 20 new".

    "As you know the 8.3 then NAT requires to use the original instead of the address translated to the ACL, but I don't know if this applies to crypto ACL as well. Pointers?

    There is no such requirement and ACL target you in the engine crytop for the tunnel bound traffic can be a natted post address, that's what shows Cisco Doc and it is correct.

    Hope that answers your questions.

    Thank you

  • Problem IBM Lotus iNotes 8.5 ssl clientless web vpn - ASA5510 v.8.2(2) OS

    Hello

    I have problems to display Lotus iNotes through Domino 8.5 correctly a page Web the VPN without client in my Cisco ASA5510.

    One of our customers has implemented Lotus Domino 8.5 and have portals of the individual user so that the user can each access their e-mail, calendar, journals, debates, etc..  Everything works fine on the internal network, as well as on a real SSL VPN as Anyconnect client... it is the Web page of the VPN without client that gives me a problem.

    The occurrence of beginning of questions when I configure a VPN page without client for users first access, fill in a username/password general name, and then they are taken to their first iNotes login page.  The iNotes login page looks very good, and when they connect in iNotes everything seems fine.  However, when they start clicking around in different tabs or to open an email (all nested in the VPN page without customer), things don't arise, and error occurred on the page of iNotes as "a problem has occurred that may have caused the operation to fail.  When I click on "Show Console" to get more details, I'm presented with:

    -----------------------------------------

    Users cannot open emails or create new email, neither can they do a lot of other primary functions in iNotes through this VPN without client.  Looks like the redirection to URL of the ASA's corrupting what you looking for the Domino server.  It does not work very well unlike what documentation Cisco says is "optimized for Lotus iNotes.

    Does anyone have any suggestions? , I like to stay out of the way using a single SSL certificate (loser 2-factor of authentication, and must make an exception of firewall directly on the server on the network) and stay out of the way using Anyconnect if I can help it. I also want to emphasize the iNotes specifically that gives me this problem, not the Lotus Notes client part full I could do work using Smart Tunnels.

    Troubleshooting steps, I made:

    DNS servers appropriate 1.) are defined in the firewall

    2.) I tried both full / lite of iNotes and produce both the same mistakes.

    (3.) I tried Firefox 3.6.8 IE6, IE8 on Windows 7 and Windows XP.  I think I have slightly better results than other browsers Firefox, but it is not error-free.

    4.) I studied corruption cookie by removing all the stories and turn off any browser plugins and accelerators

    Thank you!

    Have you tried to use the smart tunnels for the DWA bookmark? Can u also try mode lite with the active smart tunnel?

    Also in the description of your problem, when you say produces better results than IE Firefox, this exactly what you get?

  • Cisco first Collaboration - what is free

    Hi guys,.

    What is the free version of privileged collaboration of Cisco? I have to deploy for a client and I saw the first Collab provisioning version available for download on Cisco, is it free?

    Can provide you any document that says the same thing. Also the special collaboration of Cisco can be deployed in HA mode using two virtual machines?

    The free versions are called Standard versions, rather than the paid versions, called advanced versions.  The law requires CUCM 10.x and later, using CUWL license and is covered in the commercial documentation of CUCM.

    There is not much difference between PCP standard and advanced design.  The main reasons to choose Advanced if you have a several cluster environment. Standard does support a call (CUCM editor) or GCE and a single message processor (CUC or CUE).  The most frequent reason is that in advanced you can delegate the management of orders for different groups of users (areas of the CFP) to different administrators.  Standard mode does not allow this. There are some additional differences as the API to the North is on in advanced as well as a workflow of order process sometimes required by large companies. Those are the main differences.

    HA is another story.  There is a general process of HA supported by the BU of PCP and PCA using VMWare HA.  HA in general was not popular with the CFP because most of the people do not believe it is necessary and choose instead a different path for the resilience. Most of the deployment in a way people distributed (app + database of VMs) and make the system of database as fault tolerant as possible/necessary using characteristic database process in the industry. The application server uses VMWare HA or FT to come up if the configuration hardware server dies for some reason any. Or is it just launched somewhere else.

    CFP has the ability to re-synchronization of network UC, UC network will continue to operate without running of PCP and the native interfaces of UC apps can still be used (PCP can catch up with the changes later), the need to spend more money and time to configure HA is difficult to justify in most cases.
