Issue of ASA NAT and routing

• Log each ASA connection and router

  Hello

  I have a Cisco ASA 5520 and a Cisco 3825 router in my network. I want to log every connection to these devices. There are a few users who have different levels of access to these devices in n/w. I would like to connect all these users and what they actually change and to implement in the devices. Is this possible using a RADIUS server or any other method pls. I also have access to reading / writing to these devices. Thank you very much

  You can do it too.

  You can use auth-proxy (router) passage proxy (ASA) to have the user to authenticate to the connections he and do accounting of GBA. But I don't think you need to do this for all connections, for those who require the intervention of the user.

  Let us know if that answers the question.

  So the question is what is the cause of the problem? How to troubleshoot? What is the troubleshooting steps?

  Hi Eugene Khabarov

  His does not work since the address IP of Destination that represents common Services is be routed locally to the THIS itself. That's the problem here. We must ensure that the Destination subnet is not pointing to what is happening here.

• Between asa 5510 and router VPN

  Hello

  I configured ASA 5510 to vpn LAN to LAN with router 17 857. and between the routers.

  between vpn routers works very well.

  from the local network behind the ASA I can ping the computers behind routers.

  but computers behind routers, I cannot ping PSC behind ASA.

  I have configured the remote access with vpn cisco 4.X client, it works well with routers, but cannot work with asa.

  the asa is connected to the wan via zoom router (adsl)

  Are you telnet in the firewall?

  Follow these steps to display the debug output:

  monitor terminal

  farm forestry monitor 7 (type this config mode)

  Otherwise if its console, do "logging console 7'.

  can do

  Debug crypto ISAKMP

  Debug crypto ipsec

  and then generate a ping from one device to the back of the ASA having 192.168.200.0 address towards one of the VPN subnets... and then paste the result here

• Based on the IOS VPN Lan-to-Lan (NAT and route map Questions)

  Hello world

  I worked on my review of CCNA security and I have a question about this stage

  LAN1 192.168.0.0/24---(routeur HQ)--10.10.10.0/30--(INTERNET)--20.20.20.0/30--(routeur Branch) - LAN2 192.168.1.0/24

  I use 10.10.10.0/30 and 20.20.20.0/30 networks assuming that these are public addresses (is just a laboratory).

  I read that if I want to make the VPN tunnel while I using NAT I must exclude valuable traffic from the NAT process so I look on the database of cisco for more help and I found this (look at the 3660 router configuration):

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a008045a2d2.shtml#T1

  so, I applied this config for my routers, so the config is:

  IP nat inside source map route sheep interface fastEthernet0/1

  access list 110 deny ip 192.168.0.0. 0.0.0.255 192.168.1.0 0.0.0.255

  access list 119 permit ip 192.168.0.0. 0.0.0.255 any

  sheep allowed 10 route map

  corresponds to the IP 110

  I didn't really understand who is using the command route-map here, so I made this configuration:

  IP nat inside list sheep interface FastEthernet0/1

  sheep extended IP access list

  deny ip 192.168.0.0 0.0.0.255 192.168.1.0 0.0.0.255

  Licensing ip 192.168.0.0 0.0.0.255 any

  Two of them worked I could translate my LAN addresses to the public to address internet and also could establish the VPN tunnel. So my questions are:

  1. What is the purpose of the road-map command?

  2. What is the difference between these two configuration?

  3. which one I should use and in what cases?

  Thanks in advance

  Jose

  Jose,

  Very good questions and in fact no need to the road map it.

  Personally, I like using course maps because it allows much more flexibility than simply ACL setup, but in order to bypass the NAT source IPs, there is no need of route-maps and you can do this with the ACL directly.

  I personally always use road-maps just because I can (route-maps are cool) haha

  Route-maps are very useful in other scenarios where you need to put more of conditions or factors.

  Remember that it is almost always more than one method to accomplish a task... which is one of those cases.

  It will be useful.

• Issue of ASA 5540 and secure desktop Configuration

  Hey guys, I have the program installation and tested AnyConnect VPN and Cisco Secure Desktop successfully.

  Here's my question: is it possible to install two groups of VPN users, using Secure Desktop and who does not. Example of the groups below:

  Group 1: Corporate computers laptops that are not standard AnyConnect VPN Secure Desktop client.

  Group 2: Contractor and personal computers that cannot use the Cisco Secure Desktop via AnyConnect VPN.

  Thanks for you help guys!

  It is now possible to the 8.2.1. You can disable the CSD on a per database connection profile, you use Group URL subject.

• FVS336GV2 Nat or routing?

  I'm trying to secure our home network a little more until it gets 'tested '.

  I understand NAT, and routing. What I do not understand how the FVS336GV2 can do without NAT routing or if that's what he does.

  On my network - Mode WAN Configuration, I can choose "use NAT or classic routing between WAN & LAN interfaces?"

  What "Classic routing" done differently and it's better than NAT?

  I have Google had this, and found a lot of things on the hardware vs NAT and firewalls and software and more, but nothing as compared to NAT vs routing in the same device...

  I'm not sure you understand NAT or why it is necessary.

  Answer this question - do you need to share a single public ip address between several devices - or in the case of a double router WAN as the FVS336G, two public ip addresses?

  If the answer is Yes, then the classic routing isn't an option, you MUST use NAT, and you are likely to see a comparison between the two - they consider mutually exclusive options, which do different things.

  If you used the FVS336 as a router classic connected to the internet (and Yes, you can use this way), you need a public routable ip address for all devices on its LAN interface

• Exempt NAT and in cisco ASA intervlan routing scenario

  Hi, I'm new to Cisco ASA. I did some study on Cisco ASA recently and you try to understand how it works.

  The chart above illustrates the architecture of network in my company (attachment). The two FW (5520, version 8.0) are configured with nat control and same-security-traffic permit inter-interface. I have a ping of device A to unit B (10.10.105.244 > 10.10.70.70/24).

  At FW 02, I added an inbound ACL (10.10.105.0/24 > 10.10.70.0/24) because of the difference in level of security between the input and output interface (SL 50 < sl="" 100).="" for="" the="" return="" traffic="" (10.10.70.0/24=""> 10.10.105.0/24), I only need to add a device nat exempted from the rules as I have it configured with permit same-security-traffic inter-interface. My understanding is correct?

  FW 01, I need to add an entry ACL (10.10.70.0/24 > 10.10.105.244). Without the rule, my ping will be unsuccessful. Can I know why I need to add this rule to incoming traffic, because same-security-traffic permits inter-interface is set to FW 01? Can I know why I have no need to nat exempt traffic (10.10.105.0/24 > 10.10.70.0/24)?

  Sorry for the long explanation. I hope to get clarification and to ensure that my interpretation is correct.

  Thanks for all the comments. Have a nice day :)

  Hello

  For your first question: ""I know why I need to add this rule to incoming traffic, because the same-security-traffic inter-interface permit is set to FW 01?".

  It probably has to do with the ICMP inspection. By default, ICMP traffic is not inspected by the ASA for the return of the device traffic B to the device will be dropped on FW 01. You must activate the ICMP inspection by adding it to the MPF on the SAA default configuration.

  For your second question: "I know why I don't not need to nat exempt traffic (10.10.105.0/24 > 10.10.70.0/24)"?".

  NAT-control does not affect the same security interfaces, i.e. the same security interfaces can communicate without NAT even if NAT-control is turned on (with some exceptions). See this link for more information.

• VPN between ASA and router

  Hi all

  First of all, I would like to say I'm trying to implement this on Packet trace. I would like to set up a VPN using an ASA 5505 and a Cisco router 1841 (both available on Packet trace).

  The devices can ping external IP address on the other.

  The problem is that the VPN is not established. If I run sh crypto control its isakmp on the SAA, he said: there are no SAs IKEv1

  Configurations for both devices are attached.

  No idea why it doesn't work? Sorry if it is not the right forum for this, is the first time I post. I've searched the forums and I checked some of the proposed solutions, but I have not found the answer to my problem :-(

  Thanks in advance,

  Patty

  1. On the router, there is no crypto card. Need in a manner consistent with the SAA.
  2. Your policy of phase 1 is not compatible. They settings must match on both sides (router: 3des, ASA: aes)
  3. You can adjust your NAT on both devices that tunnel traffic does not get teeth. Remember that NAT is made prior to IPsec. If you do not exempt NAT traffic, then it will not match the ACL crypto more after NAT.
  4. Yes, the forum is perfectly fine! ;-)

  Hello

  I quickly browsed your config and I could notice is

  your game of transformation (iskamp) on SAA and router are not the same, try to configure the same on both sides.

  in the statement of the ASA NAT you gave (any, any) try to give the name of the interface instead of a whole.

• Order of procedure SonicWALL for routing, NAT and policies

  I'm confused on the prescription that the sonicwall verifies a package.  The way I heard the order, it will:

  (1) check against the access rules,

  (2) check against NAT Polies

  (3) check the routing.

  Installation program:

  Subnet point of VPN endpoint - Internet - SW NSA 2400 (VPN) - sub-network B (from C subnet)

  A subnet is 10.1.100.x/24

  Subnet B is consists of three IPs, 192.168.99.4,.50, and 109.

  Subnet C is contains the host IPs 192.168.13.4,.50, and 109.

  I VPN configured to allow traffic from 10.1.100.x to the hosts on the subnet B, what NAT and the host subnet C.  This method works more large, is not a problem.

  I need to reduce access to certain ports.  Once I set access restrictions in the port, the firewall blocks ALL.

  When I look at a screenshot of packets when traffic is blocked, I see the following:

  Source 10.1.100.5--> 192.168.99.4 accepted

  Source 10.1.100.5--> 192.168.13.4 refused.

  Block of code indicates that it is because of politics.  However the policy review should have been checked and checked already.  If I change the VPN policy to represent both sides of the NAT (ie. 192.168.99.4 and 192.168.13.4) then passes the traffic.

  If anyone can explain what is happening?

  I tried to look through some KB SonicWall has publicly available articles. But I did not see anything that doesn't seem to help. In this case, I think you might want to give SonicWall support a call.

  https://support.software.Dell.com/manage-service-request

  They can help to look over your configurations and see if we have to make changes. They should also be able to answer your technical questions about how the packets are received or managed.

• ASA NAT to 8.4

  I'm doing the VPN tunnel between router IOS and ASA 5505. The ASA has a dynamic IP address

  Everything would be ok, but I don't understand NAT in ASA's new orders. Can you tell me how to convert it to version 8.3 - 4?

  access-list no. - NAT allowed extended ip 10.1.1.0 255.255.255.0 10.2.1.0 255.255.255.0

  Global 1 interface (outside)

  NAT (inside) - No. - NAT 0 access list

  NAT (inside) 1 0.0.0.0 0.0.0.0

  I use this link

  http://www.Cisco.com/c/en/us/support/docs/security/PIX-500-series-Securi...

  Thanks for any help.

  Take a look at the document, depending on where you can find almost everything on the new model of NAT:

  https://supportforums.Cisco.com/document/132066/ASA-NAT-83-NAT-operation-and-configuration-format-CLI

  Especially "NAT0 / NAT Exemption / identity NAT ' in part"TWICE-NAT-MANUAL-NAT"is relevant for this task.

• Issue of ASA 5510

  Dear all,

  I applied ASA 5510 in my network,

  I configured 3 DMZ, inside and outside interfaces

  ASA, I can access the Interior, DMZ and outside (Internet)

  Inside users can communicate with the servers in the DMZ

  Inside users goto Internet via the external interface

  DMZ servers can goto Internet via the external interface

  The DMZ servers cannot Ping inside the network

  I've been using IpSec VPN on my router,

  clients connect to the router using the Cisco VPN Client software,

  NOW, when I understood ASA in the network, VPN clients are unable to communicate with the servers in the DMZ

  security level 0 for outside

  DMZ 50

  100 for the inside

  NAT is disabled with no command nat control

  What I need to ON the NAT and some ACL must be put in place...

  Please advise me what ACL I should implement, interface? Direction?

  Which statement NAT should I include?

  I want to access my network via VPN...

  Help, please

  Kind regards

  ICMP pings are not stateful. The firewall needs special treatment to dynamically allow pings back, this is done through the "ICMP inspection." The ICMP inspection is disabled by default. You can activate the inspection or use an ACL to allow ICMP traffic. Here is a useful link:
