• Remote access ASA, VPN and NAT

  Hello

  I try to get access to remote VPN work using a Cisco VPN client and ASA with no split tunneling. The VPN works a little, I can access devices inside when I connect, but I can't access the Internet. I don't see any errors in the log ASA except these:

  1 Jul 04:59:15 % ASA-3-305006 gatekeeper: failed to create translation portmap for udp src outside:192.168.47.200/137 dst outside:192.168.47.255/137
  1 Jul 04:59:15 % ASA-3-305006 gatekeeper: failed to create translation portmap for udp src outside:192.168.47.200/54918 dst outsidexx.xxx.xxx.xxx/53

  There is only one address public IP that is assigned to the external interface of DHCP. The Interior is 192.168.1.0/24 network which is PAT'ed to the external interface and the VPN network is 192.168.47.X.

  I think my problem is that the net.47 is not NAT'ed out properly and I don't know how to put in place exactly. I can't understand how this is supposed to work since the net VPN technically provenance from the outside already.

  Here are all the relevant config:

  list of vpn access extended permits all ip 192.168.47.0 255.255.255.0
  Within 1500 MTU
  Outside 1500 MTU
  IP local pool vpnpool 192.168.47.200 - 192.168.47.220 mask 255.255.255.0
  IP verify reverse path to the outside interface
  IP audit info alarm drop action
  IP audit attack alarm drop action
  ICMP unreachable rate-limit 1 burst-size 1
  ICMP allow all outside
  Global interface (2 inside)
  Global 1 interface (outside)
  NAT (inside) 0-list of access vpn
  NAT (inside) 1 0.0.0.0 0.0.0.0
  NAT (outside) 2 192.168.47.0 255.255.255.0 outside
  static (inside, outside) tcp 3074 XBOX360 3074 netmask 255.255.255.255 interface
  static (inside, outside) udp 3074 XBOX360 3074 netmask 255.255.255.255 interface
  public static (inside, outside) udp interface 88 88 XBOX360 netmask 255.255.255.255
  public static tcp (indoor, outdoor) https someids netmask 255.255.255.255 https interface

  I can post more of the configuration if necessary.

  Change ' nat (outside) 2 192.168.47.0 255.255.255.0 apart ' "NAT (2-list of vpn access outdoors outside)" gives these:

  1 Jul 06:18:35 % gatekeeper ASA-3-305005: no group of translation not found for udp src outside:192.168.47.200/56003 dst outside:66.174.95.44/53

  So, how I do right NAT VPN traffic so it can access the Internet?

  A few things that needs to be changed:

  (1) NAT exemption what ACL must be modified to be more specific while the traffic between the internal subnets and subnet pool vpn is not coordinated. NAT exemption takes precedence over all other statements of NAT, so your internet traffic from the vpn does not work.

  This ACL:

  list of vpn access extended permits all ip 192.168.47.0 255.255.255.0

  Should be changed to:

  extensive list of access vpn ip 192.168.47.0 255.255.255.0 allow

  (2) you don't need statement "overall (inside) 2. Here's what to be configured:

  no nat (outside) 2 192.168.47.0 255.255.255.0 outside

  no global interface (2 inside)

  NAT (outside) 1 192.168.47.0 255.255.255.0

  (3) and finally, you must activate the following allow traffic back on the external interface:

  permit same-security-traffic intra-interface

  And don't forget to clear xlate after the changes described above and connect to your VPN.

  Hope that helps.

• Diffie-Hellman - ASA firewall groups

  Hi all

  A couple of questions I hope you can help me with that.

  Please can you tell me where I would change the Diffie-Hellman group for phase 1 on an ASA firewall and is - it possible on the ASDM?

  Also, you must enable PFS have to DH on the phase 2?

  Thank you very much

  Alex

  Hello Alex,.

  You can change the Diffie-Hellman group for phase 1 of ASA by configuring the following command:

  crypto ISAKMP policy

  Group

  To configure the same ASDM, go to the

  Configuration > VPN Site to Site > connection profiles > add/edit

  You will find in settings, IPsec, encryption algorithms. Click on 'Manage' icon on the right of "IKE policy". Click OK.

  Click on Add/Edit and there will be an option to change the Diffie-Hellman group.

  And finally, what about the PFS application, you can enable PFS to be DH in phase 2. activation of PFS will force a new Exchange of key DH for phase 2.

  Note: it is not mandatory, its optional. If its configured on one side, then it must be on the remote side as well.

  Kind regards

• Cisco ASA Site to Site VPN IPSEC and NAT question

  Hi people,

  I have a question about the two Site to Site VPN IPSEC and NAT. basically what I want to achieve is to do the following:

  ASA2 is at HQ and ASA1 is a remote site. I have no problem setting a static static is a Site to IPSEC VPN between sites. Guests residing in 10.1.0.0/16 are able to communicate with hosts in 192.168.1.0/24, but what I want is to configure the NAT with IPSEC VPN for this host to 10.1.0.0/16 will communicate with hosts in 192.168.1.0/24 with translated addresses

  Just an example:

  N2 host (10.1.0.1/16) contacted N1 192.168.1.5 with destination host say 10.23.1.5 No 192.168.1.5 (notice the last byte is the same in the present case,.5)

  The translation still for the rest of the communication (host pings ip destination host 10.23.1.6 N3 N2 not 192.168.1.6 new last byte is the same)

  It sounds a bit confusing to me, but I've seen this type of configuration before when I worked for the supplier of managed services where we have given our customers (Ipsec Site to Site VPN with NAT, don't know how it was setup)

  Basically we contact the customer via site-to-site VPN hosts but their real address were hidden and we used as translated address more high 10.23.1.0/24 instead of (real) 192.168.1.0/24, last byte must be the same.

  Grateful if someone can shed some light on this subject.

  Hello

  OK so went with the old format of NAT configuration

  It seems to me that you could do the following:

  • Configure the ASA1 with static NAT strategy
    • access-list L2LVPN-POLICYNAT allowed ip 192.168.1.0 255.255.255.0 10.1.0.0 255.255.0.0
    • public static 10.23.1.0 (inside, outside) access-list L2LVPN-POLICYNAT
  • Because the above is a static NAT of the policy, this means that the translation will be made only when the destination network is 10.1.0.0/16
  • If you have for example a PAT basic configuration to inside-> external traffic, the above NAT configuration and the custom of the actual configuration of PAT interfere with eachother
  • ASA2 side, you can normally configure NAT0 / NAT Exemption for the 10.1.0.0/16 network
    • Note of the INTERIOR-SHEEP access-list SHEEP L2LVPN
    • the permitted INSIDE SHEEP 10.1.0.0 ip access list 255.255.0.0 10.23.1.0 255.255.255.0
    • NAT (inside) 0-list of access to the INTERIOR-SHEEP
  • You will need to consider that your access-list defining the VPN encrypted L2L traffic must reflect the new NAT network
    • ASA1: allowed to access-list L2LVPN-ENCRYPTIONDOMAIN ip 10.23.1.0 255.255.255.0 10.1.0.0 255.255.0.0
    • ASA2: list L2LVPN-ENCRYPTIONDOMAIN allowed ip 10.1.0.0 access 255.255.0.0 10.23.1.0 255.255.255.0

  I could test this configuration to work tomorrow but I would like to know if it works.

  Good news, that VPN has been implemented!

  According to the ping problem, my suggestion is to check, if some type of firewall based on host computers on both sides block ICMP requests.

  Anyway, you can still use the capture of packets on the inside of the interfaces of the two ASAs, to check if the ICMP traffic is to reach the ASA.

  In addition, you can try to enable ICMP inspection:

  Policy-map global_policy
  class inspection_default

  inspect the icmp

  Mattew, obvious lack of education is the rule exempt from nat for your tunnel, your access list pixtosw is similar on this example, I assume that you have gone through this link, if it does not see the configs on both sides.

  Add the statement of rule sheep in asa and try again.

  Concerning

• ASA firewall identity

  Hello

  I have setup a firewall of identity on an ASA version 5.6 on a DMZ interface.

  I installed the ADAgent on a Win2008 domain member and configured as follows:

  RADIUS protocol AAA-server ADAGENT_SERVER

  mode-agent-ad

  key 172.17.v.x AAA-server host ADAGENT_SERVER (VPN) *.

  I have configured the LDAP connection to the following domain controller:

  AAA-server DOMAIN_SERVER protocol ldap

  AAA-server DOMAIN_SERVER (VPN) host 172.17.v.z

  LDAP-base-dn DC = YYY, DC = local

  LDAP-scope subtree

  LDAP-login-password *.

  LDAP-connection-dn Lucas

  microsoft server type

  The configuration of the identity is:

  field of the identity of the user YYY aaa-Server DOMAIN_SERVER

  identity of the user by default-domain YYY

  netbios-response-fail action, remove-user-ip user identity

  user logout-probe netbios local system identity

  identity of the user-agent ad server aaa-ADAGENT_SERVER

  allow the user not found-identity of the user

  122 extended access-list allow the user ip YYY\ashdew a whole

  where ashdew is a domain user and ACL 122 (as one line) is applied on the interface of the dmz and NAT is configured correctly.

  The ADagent has been properly tested and ASA may join it.

  The ASA can connect to the DC AD controller and database user query.

  I placed a portable ip 172.17.h.x on the DMZ and can test the DMZ interface.

  The portable computer cannot authenticate to the domain and the asa does not seem to recover the identity of the user

  Do I need to add additional rules in the access list 122 to allow DC traffic?

  Can I record on the Agent AD if it can recover the user ip mapping?

  Thank you

  Ashley

  Hi Ashley,

  It must ensure that the domain controller is configured correctly, please follow the instructions here:

  http://www.Cisco.com/en/us/docs/security/IBF/setup_guide/ibf10_install.html#wp1058066 (Configuration AD Agent to get information from AD domain controllers)

  I suggest first check connection events are generated in the security of the domain controller event log. In 2008 of Windows, you will see event ID 4768. If they are not, you will need to modify the audit policy, as described in the link above.

• ASA 5520 and MPF

  Hi all. In our company we have recently upgraded our PIX 515 firewall to ASA 5520, and we started to live a thing strange event. On one of the sites we host, I saw a lot of outdated SSM messages popping up and I think that they are the source of the problem when they surf the site (mainly surfing works fine, but sometimes people cannot content etc.).

  I found the Cisco solution for this problem by using the MPF, but one thing confuses me. If I ask a MPF allowing adults MSS on the external interface of the ASA does this political conflict with the comprehensive policy that is on the SAA by default or can they both at the same time?

  Thanks in advance for any help.

  You can have a single policy per interface and another - global, that by default applies to default-inspection-traffic.

  See http://www.cisco.com/en/US/docs/security/asa/asa80/configuration/guide/mpc.html for more details.

• ASA 1000V and ASA 5500

  I hope someone can help me to answer this question:

  Currently, we have redundant FWSM and consider a migration of standalone ASA 5500 series firewalls. However, we have a complete VMWare environment and look at the Nexus 1000V. I understand the Nexus 1000V and ESR architecture and implementation, and I don't understand that the ASA 1000V is designed for cloud environments. But I have a question about the ASA 1000V.

  Is it possible that a firewall series ASA 5500 be replaced by ASA 1000V? Basically, can an ASA 1000V to be a single firewall solution, or are that ASA 5500 is always necessary?

  Is there a datasheet anywhere that compares the ASA 1000V and ASA 5500 series?

  Thanks for your help.

  -Joe

  Depending on what you are using the ASA5500 series for now. If you use the ASA5500 for the remote access vpn and AnyConnect VPN, he will not rely on the first version of the ASA1000V yet.

  Here's the Q & A on ASA1000V which includes more information:

  http://www.Cisco.com/en/us/partner/prod/collateral/vpndevc/ps6032/ps6094/ps12233/qa_c67-688050.html

  Hope that answers your question.

• Multiple VPN groups on the ASA firewall

  I have a remote VPN configured in my ASA firewall with a group of users configured on the external ACS VPN. The group called VPNASA to authenticate via the ACS server and the server ip pool is on the firewall of the SAA. Now, my boss asked me to set up a second VPN group called VPNSALES on the ACS server for the same remote VPN on the ASA firewall. How to configure the firewall for the ASA to accept both the Group and authenticate on the same ACS server? I've never done this before so I need help.

  Thank you very much!

  Hello

  all you need to do is create another group strategy and attach it to a group of tunnel: -.

  internal vpnsales group policy

  attributes of the strategy of group vpnsales

  banner - VPN access for the sales team

  value x.x.x.x DNS server

  split tunnel political tunnelspecified

  Split-tunnel-network-list split-sales value

  address-pools sales-pool

  value by default-domain mydomain.com

  type tunnel-group vpnsales remote access

  tunnel-group vpnsales General-attributes

  authentication-server-group vpnsales

  Group Policy - by default-vpnsales

  vpnsales ipsec tunnel - group capital

  pre-share-key @.

  you will also create a map of the attribute named vpnsales for acs auth.

  Thank you

• Hub topology and talk: can I traffic Internet road to PC at a radius of the site through the tunnel and NAT outside in the world on the 5520 hub?

  I don't know if it can be made to work or not, or if it's a mutually excluded NAT configuration that is not possible, but I have a 5520 ASA to my site central office with a fiber of 20Mbps Internet streams and two remote offices with ASA 5505 devices connected via DSL or cable modem and have finally got from Site to Site "spoke" VPN upward tunnels and run with the ability to route traffic to through a 'hairpin turn' speak-to-Spoke on the Hub Site 5520.

  I have desktop PC at each remote site speaks A & B that need to communicate directly with them to support a small group of work-style of the software point of sale that is actually hosted on a remote site A PC.

  PC on two remote sites must also be able to communicate with a credit card processing by the public Internet service, and I wish have the ASA 5505 units in each block of remote office as all traffic directly NAT'ed from each respective out on the local LAN PC straight Internet above each site cable modem or DSL modem. I want to force these PCs need to NAT their Internet-destination back through the ASA 5520 traffic located at the Home Office, on the VPN tunnels. In other words, I want the cable modem and DSL connections to route traffic strictly VPN encrypted to the Home Office and also behave like routers NAT for the local PC it.

  I can kill the 5505 prevents NAT for PCS in remote offices simply removing the rule dynamic NAT factory default for 'everything', but then I can't understand how to get my 5520 central to perform NAT which required of the remote PCs to talk to their service of Internet credit card processor without breaking the configs "NAT-free" necessary for VPN traffic to spoke-to-spoke to work. If I'm trying to put an entry static or dynamic NAT for a remote desktop on my 5520 ASA central, it breaks the VPN tunnel so that PC specific.

  Is that what I want to accomplish even possible with the ASA?

  Hi Neal,

  Yes, it's quite possible! below is a loss of things you need to do:

  (1) make sure of course on both the 5505 s of the ASA, you send ALL traffic from the local network through the VPN.

  (2) as Andrew mentioned, have the 'same-security-traffic permit intra-interface' command on the ASA 5520.

  (3) you do not have to have a configured proxy server, but it is also a good solution. But to make it work without her, assuming that the ASA 5505 remote subnets 192.168.1.0/24 and 192.168.2.0/24, add the config lines below to the ASA 5520:

  NAT (outside) 1 192.168.1.0 255.255.255.0

  NAT (outside) 1 192.168.2.0 255.255.255.0

  Global 1 interface (outside)

  Please note that 1 id, and the interface can be replaced according to the configuration you already have in place in the ASA 5520.

  I don't know what kind of NAT exemptions are at the origin of the questions for you, but if you can put a sanitized one of your ASA 5505 and ASA 5520 config, I can make suggestions concerning the exact configuration.

  Let me know if it helps!

  Thank you and best regards,

• Firefox cannot connect to the internet, while the other browsers can... have deleted the software and reinstalled... turned off firewall and virus program.

  Delete a few files TEMP this morning and AOL and Firefox no longer works. AOL will again and removed all traces of the first installation of Firefox and downloaded a new version of Firefox. The program opens, but it immediately goes into a status of "not responding" and appears in the tab 'connection '. Cannot click on anything on the Firefox screen. Need to go to the Task Manager to kill the program. Have removed and reinstalled several times. Disconnected the firewall and antivirus. Again and always get the same result. Tried in safe mode. Same result. Going on 8 hours of work on this thing. Need help badly. The system is a version update of XP.

  Thank you all, but I gave up. Tried all the suggestions without success. Put at disposal of the HDD with Windows XP and the problem of Firefox and loaded Windows 7 on a new drive. I had saved a file backup Favorites from the XP machine and successfully migrate the new hard drive. Thanks again.

• McAfee Firewall and analysis

  I have a Center B520 idea with the following installed: -.

  NET BT more (McAfee) installed through my Internet BT package

  Upgrade of Windows 8 (which has updated to Windows 7, which was originally installed)

  Last week, a message appeared telling me that the McAfee Firewall and Anti Virus have been disabled.

  When I went to them I couldn't turn on them. I removed and then reinstalled BT Net more, but it has not fixed the problem.

  I thought then that I would do a system restore to an earlier date, but at the end of the present, I got the following error message:

  System restore failed during the removal of the following

  Path C:\Windows\System32\DRIVERS\b95df1c913bec87a.sys

  an unexpected error occurred 0x8007007b

  I also seem to have lost the ability to restore the complete system for the default option.

  Anyone has any ideas on what might solve this problem, and also, is there a way I can now restore the system to its original state with Windows 7

  Thanks for any help

  Hello solid,

  Sorry for the delay in response. I tried what you said but not good. The problem was because I had installed Windows 8 Upgrade over the original factory installation Windows 7. This disables the restore a key.

  I talked to technical Lenovo who pointed me in the direction of the restoration of disks. I now have these and have restored the computer back to its "factory settings (so the delay). The problem with McAfee has now been resolved.

  I think that the computer has been infected by a virus, but the cleaning system all corrected now.

  Thanks for your help.

  Hey Roscoe,

  If you're still using MSE, I doubt there's this problem.  This made a few changes to the Windows Firewall during installation (if necessary), but certainly nothing that would cause it to turn on and off like that.  It could be malware (malware can cause anything), but frankly more sounds like a file systems or corruption or some type of problem with your Windows Firewall or security setting or your operating system in a more general sense rather than the malicious software.  I will refer you to experts who specialize in this kind of thing, but if they tell you it's a malware problem, then come back here and we will be happy to help you solve it.

  For that matter as described, please post here to get the best advice from specialists in this: http://answers.microsoft.com/en-us/windows/forum/security?tab=all which will be more than happy to help you.  You will probably need to uninstall the other firewall you have installed so they can diagnose the problem properly and without hindrance (not just disable it, but completely uninstall to be sure) - but they can tell you more on this subject.  Don't forget up next to the Windows Version to use the dropmenu to choose your version if you find yourself in the most appropriate forum for your system.

  I hope this helps.

  Good luck!

  In Windows 7, you cannot uninstall a firewall, you can simply enable the firewall MARKET (if you wish). Just please refer to the article below and use the steps provided to disable the firewall or ON -.

  WARNING:

  You should not turn off Windows Firewall unless you have another firewall is enabled. Turning off Windows Firewall may make your computer (and your network, if you have one) more vulnerable to damage caused by worms or hackers.

   

  I hope this helps.
