• Cisco ASA, connect an IP address on the OUTSIDE of the VPN remote access

  Hello

  I tried to find resources on the net but could not find a solution, then post it here. Maybe someone can help.

  So the problem is that I'm trying to access a server on the cloud for remote VPN access (cisco asa 5510).

  The server on the cloud (54.54.54.54) is only accessible from the outside interface (192.168.11.2) NY Firewall (cisco asa 5510)

  I added some ACE for this in the ACL of VPN tunnel to divide.

  NY-standard host allowed fw # access - list vpn_remote-customer 54.54.54.54

  And I see the road added to my cliet machine after the VPN connection, but still it cannot connect to this server.

  The network INTERIOR, I can connect to the server.

  

  Thanks in advance.

  Hello

  This is most likely a problem with NAT hair/U-turn hairpin.

  Will need to see the configurations or you would need to check yourself

  I don't know what your version of the Software ASA is to be like who determines what is the format of NAT configuration.

  So far, you have confirmed that the ASA VPN configuration provides the VPN Client with the route to the remote server. Then in circulation should be tunnel to the ASA.

  Then, you will need to check the output of this command

  See the race same-security-traffic

  You should see the command in the output below

  permit same-security-traffic intra-interface

  If you do not, you will need to add it. This effect of controls is to allow traffic to enter an interface and exit through the same interface. In your case this applies to Internet VPN Client traffic to the remote server as it between ' outside ' and spell through the 'outside'.

  Then, should ensure that dynamic PAT is configured for the VPN Clients.

  8.2 software (and below)

  You most likely have a dynamic configuration PAT like that on the firewall, if levels of above running software version

  Global 1 interface (outside)

  NAT (inside) 1 0.0.0.0 0.0.0.0

  In this situation if we wanted to add dynamic PAT for a pool of VPN, we would add

  NAT (outside) 1

  This would allow users to use the same public IP address as LAN users, when accessing the remote VPN server

  Software 8.3 (and above)

  Because the NAT configuration format is completely different in the latest software, you could probably just add a new configuration of NAT completely without adding a

  network of the VPN-PAT object

  subnet

  dynamic NAT interface (outdoors, outdoor)

  Of course, its possible that there could be some configuration NAT already on the device which could cause problems for this configuration. If this does not work then that we would have to look at the actual configurations on the ASA.

  Hope this helps

  Let me know how it goes

• Cisco ASA 8.4.1 address Destination NAT?

  I have a situation where I have a deployed asa5505 8.4.1 running.

  The customer has a mail server existing which is located on their local network and has Port configured NAT for normal mail ports, etc. 25,110,993,587.

  It works very well for incoming mail and any jerky mail user off the external server or by visiting the webmail from outside the network.

  However when the users within the LAN to connect through the ASA test back entering the IP address on the external Interface of the ASA, they are unable to do so.

  I came up with the solution is split DNS.   well does he rely on users not changing their dns servers.

  I was wondering if it is possible to make a sort of NAT that rewritten traffic destined to the above ports on the external IP address to the internal LAN Ip instead.

  This is probably a stupid question, but I couldn't find an answer may I use the terms wrong to get one.

  In any case, I was hoping someone here could point me in the right direction.

  Thank you

  You can only configure DNS rewrite rewrite if you have static NAT 1 to 1, with static PAT as advised, rewriting DNS is not supported because with PAT static, it is potentially different internal IP mapping, so the DNS rewrite is not exactly at the right address.

• L2l VPN between ASA with the IP address public and CISCO2911 behind the ISP router with port forwarding

  Hi all

  My apologies if this is a trivial question, but I spent considerable time trying to search and had no luck.

  I encountered a problem trying to set up a temporary L2L VPN from a Subscriber with CISCO2911 sitting behind the router of the ISP of an ASA. ISP has informed that I can't ignore their device and complete the circuit Internet on the Cisco for a reason, so I'm stuck with it. The Setup is:

  company 10.1.17.1 - y.y.y.y - router Internet - z.z.z.z - ISP - LAN - 10.x.x.2 - XXX1 - ASA - 10.1.17.2 - CISCO2911 - 10.1.15.1 LAN

  where 10.x.x.x is a corporate LAN Beach private network, y.y.y.y is a public ip address assigned to the external interface of the ASA and the z.z.z.z is the public IP address of the ISP router.

  I have forwarded ports 500, 4500 and ESP on the ISP router for 10.1.17.2. The 2911 config attached below, what I can't understand is what peer IP address to configure on the SAA, because if I use z.z.z.z it will be a cause of incompatibility of identity 2911 identifies himself as 10.1.17.2...

  Q2) I believe that the ip address of the primary (Standby) in aid will be

  10.1.1.2

  10.2.1.2

  It will use what mac addresses? What is the BIA of the secondary unit? Please notify

  Thanks in advance.

  Q1 Yes), IP address and the MAC will be moving to the new active unit so no matter who the network except the switch will notice failover event

  Q2) Yes, primary (watch now) will use IP addresses and MAC addresses available for secondary:

• Cisco ASA 5510, ipsec vpn. What address to connect the client to

  Hello

  It's maybe a stupid question, but I can't find the answer anywhere.

  I used the ipsec vpn configuration wizard, I activated the external interface to access ipsec and went through SCW pools of addresses etc. When I try to connect with the cisco vpn client to my address of the external interface (of a remote host) I'm unable to connect. I scanned the interface for open ports, but there is not, I have to allow traffic to ipsec at this interface?

  Best regards

  Andreas

  No, once you have configured the access remote vpn ipsec, it will be automatically activated, and you should be able to connect to the ASA outside the ip address of the interface.

  Can you please share the configuration? and also which group name you are trying to access the vpn client?

• The AIP - SSM to unused ASA connection interface

  Hi people,

  Perhaps, someone has already raised this issue, but I was unable to find anything relevant. We have an ASA with an unused interface (gig0/3). The sensor of the AIP - SSM is physically connected to this interface with the following IP settings:

  Sensor (192.168.2.2/30,192.168.2.1)---interface ASA (192.168.2.1/30)

  It's basically point to point connectivity, and I can reach the ASA of the sensor and the other way around.

  This design is dictated by the lack of a free port on the switch.

  Technically, it should work without any problems, but I can't seem to be able to reach the sensor. There is a switch between my PC and the sensor and the switch has the corresponding static route added. I can reach the switch sensor.

  Is there a security feature hidden I don't know that prevent communication with the sensor.

  And ACL of the sensor allows the traffic to all networks (0.0.0.0/0)

  With the sensor acl set to 0.0.0.0/0, the sensor must be allowing connectivity.

  You can use the 'View of package' command on the sensor to look at packets on the interface command and control to see if the packets are what makes the sensor.

  You say that you have a static route on your switch for the switch reach your sensor. Do you know if your PC is configured to use the switch as the computer's default router. If the PC is to use a different default router, then the other router should also the static route.

  The other possibility is that the SAA itself can be deny traffic.

  Since this is an ASA connected to the MSS interface, the traffic must be routed through the ASA. Standard firewall rules apply to this traffic. The security level of the interfaces can prevent traffic, and an ACL may be necessary in order to allow the circulation of your PC be routed to the SSM.

  NOTE: If you don't want to have to worry about roads, the other alternative is to make the network between the ASA and SSM to be an isolated network that only 2 machines know.

  You can then use PAT static to map a port on the inside of the ASA interface with the address of the SSM 443 https port and map a second port of the SAA within the interfaces to the address of the SSM SSH port.

  How your home PC would simply plug the ASA IP using these specific ports and the ASA would do the translation of port and transmit on the MSS.

  The SSM address could also be dynamically PAT would have on the SAA within the address, so SSM could start the connection to other machines on the inside network.

  Another alternative if you have addresses available on your inside network IP is to use static NAT instead of PAT. And just go forward and has the ASA statically map an IP network on IP of the SSM on the network that only the ASA and the SSM inside could know.

  In both cases the network between the ASA and SSM would not routable at, and you wouldn't have to worry of reproducing static routes anywhere.

  SIDE NOTE: A separate network for the SSM you Becase you will also need to NAT or PAT address of the SSM for the ASA to outside interface. In this way the SSM will be able to connect to Internet to download cisco.com auto updates, and/or pull overall correlation of servers cisco information. It's probably the same configuration that you would already other internal addresses, and just to be sure, you cover the SSM since you have it on a separate subnet.

• Interfaces of AIM - SSM and ASA 5510

  All, someone can explain if and how routing works between the ASA and the map of the IPS?

  (1) is the single NIC in the card IPS management purposes only?

  (2) is the IP address configured in the process of installing the card for that one NIC?

  (3) should it have no routing between for example the management of the ASA or any other interface and card management interface or can they reside on completely separate networks?

  Thank you

  Jonathan

  Map of the IPS has 3 interfaces.

  The management interface is an external interface that you plug a network cable in. The IP address is configured by the user during installation.

  Sniffing is the internal interface of data backplane ASA. No IP address is never assigned to this interface.

  Interface control plan is an internal control ASA management interface, so that the SAA can communicate internally to the SSM (the session command runs through this interface). The IP address of the control plan is controlled by the ASA and not user configurable,

  The management interface's management only.

  The IP address that is configured during installation is only for this management interface.

  Regarding the routing between the ASA and the SSM, it's completely up to the user.

  All communications from the ASA to the SSM are made internally through interface control plan and therefore the SAA itself has no need to know how to communicate on the SSM management IP.

  The SSM, however, must communicate from IP management is one of the ASA interfaces to Shunning/blocking on the SAA. Shunning/blocking is not through the control plan.

  When you use IDM or ASDM for configuration as java Web applet access to DFS management IP so the computer that runs the IDM or ASDM must be on the local network of the MSS management port, or routable network.

  Some scenarios:

  (1) only one machine (IDS MC/s LUN) communicating with the SSM. In this scenario, you could take a crossover cable and connect directly one machine to the MSS.

  The SSM can communicate only on this computer into one.

  (2) a secure network to manage security devices that is NOT routable from the other networks.

  In this scenario the box management, DFS management port and the management of the ASA port would be all placed in a network.

  The SSM would be able to communicat with the box management and the ASA management port.

  The ASA management port is configured as a management only for the ASA port will not route input/output of the management network.

  While management on this local network zone can communicate with the SSM, and no distance box cannot connect directly to the SSM.

  (NOTE: blocking/Shunning will work here because the SSM can speak to the ASA)

  (3) a secure network which IS routable from the other networks.

  Similar to option 2 above, but in this case the ASA management port is configured to NOT be a 'single management' port and is instead treated as any other port on the firewall. In this configuration, the management port of the ASA CAN road entrance/exit to the management network.

  NOTE: In most cases the ASA will need to configure a NAT for the SSM management IP address if users want to connect on the SSM management IP remotely from the Internet (such as running ASDM of the main network of the company on the internet to set up the SAA and the SSM on a remote site)

  (4) SSM management IP on one of the normal networks behind the ASA. In this screenplay DFS management port would be connected to a switch or a hub where other internal machines are connected (like jumping in the DMZ switch / vlan). The ASA point of view of the management port SSM would be treated as any other web and ssh server behind the firewall.

  There are several ways to connect the ASA CX to the internet. The simplest is to use the management only for CX port. For that connect to this port directly to your network and ASA-CX an IP address between this network with the SAA within the intellectual property as the default gateway.

  But you can also use a router internal to route between the inside and the management network.

• Cisco ASA HA - WAN mesh

  Hi all

  I have a Setup as shown below. Its an installation that is running already, having two ISP links to destination 2 switches. Since the two switches, two more coming out and links which end each firewall. Two firewalls running in HA Mode Active and standby. When I check the configuration of firewall with command two sh run, I see 2 Interfaces/firewall for isps1 and ISP2 on two ASAs. However, the IP address configured on ASA 1 ISP 1 is even what is configure on ASA 2 to 1 PSI. It is the same with 2 ISP config. Please confirm if this is correct?

  Concerning

  The two ASAs share the same configuration interface where you assign IP addresses to two units. The ASAs know what IP should be assigned to the which ASA. The ASA active Gets the primary IP address, the standby ASA Gets the IP address standby.

  use: -.

  tunnel-group xx.xx.xx.xx type ipsec-l2l

• Remote access VPN VPN Ping from ASA clients

  I would like to know if it is normal to not being able to traceroute or ping for VPN clients connected from the ASA command line? The VPN client and the connection works well at the moment. I can't ping / connect to the VPN and vice versa internal hosts. I can't ping however the ASA VPN client IP address himself well. I'm so split tunnel but that seems to work correctly based on the determination of route I ran.

  Can I have an IKEv1 and IKEv2 for VPN IPSEC configuration? I try to keep the IKEv1 VPN for the legacy Cisco VPN client while I began to roll on the AnyConnect IKEv2 client. Just end up creating a new configuration of VPN for the AnyConnect VPN (easier)?

  What is the purpose of the injection of the route the other way around? It seems to be against intuitive. I was hoping it say for VPN DHCP pool 32 come to me so I would not add static routes on my heart to point to the ASA for these ranges. This ASA is reserved for the VPN firewall not this traffic is not normally head to it. Right now I have just the static route for the 24 I use in the DHCP pool on carrots. I have of course the possibility to redistribute the beach many other ways with EIGRP / OSPF / RIP it seems to me that RRI was a nice way to do, but it doesn't seem to be.

  It probably all comes from me probably do not understand exactly how bits to pass through the firewall to the actual machine of the VPN client. You see only not an interface layer 3 for part of the ASA in the tunnel, according to me, is part of what confuses me.

  Basically, I followed this guide and added split tunnel and aaa via RADIUS which seem to work well. I can't emphasize enough that for all intent and purposes, it seems that the VPN works as it should now. Wait for this time I broke it a few hours while I was playing with various other orders lol.

  Thank you

  Tim

  Reference:
  ASA 5505 (base right now, license #labgear) 9.2 (4) running

  It is normal to not be able to ping remote VPN clients to the ASA's.  To be able to do outside the ASA IP address must be included in the field of encryption, which is not normally.

  Yes, you can use IKEv1 and IKEv2 at the same time.  However if you change consider using SSL.  It is best taken in charge and less painful.

  If you choose to ignore this advice, then I would create a new IKEv2 VPN rather than modify the existing and then migrate users through him.

  The reverse route injection does exactly what you describe.  They appear as static routes on the SAA, you will then need to redistribute in any routing protocol you like.  I wouldn't normally use for traffic of users, but for the traffic of a site when managing more complex failover scenarios.

  I recommend to stick to the single 24 static road in your kernel.

• ASA - added a public server and it is limited to this traffic

  I added an internal e-mail server to a whole new ASA5510 today.  I used the GUI because it is a fairly simple installation.  In any case, I added a mail server to allow the port 25 inbound on an address static nat dedicated to this server.  But now, this server can not do anything on the internet: the navigation or search DNS, etc..  The server is also the internal DNS server.  I'm probably missing?

  Hello

  It not on MAC address about proxy arp

  • Addresses on the same network as the interface is mapped.

  If you are using addresses on the same network that the mapped interface, the ASA uses proxy ARP to respond to all ARP requests for mapped addresses, thus intercepting traffic destined to a mapped address. This solution simplifies the delivery because the ASA is not to be the gateway for all additional networks. This solution is ideal if the external network contains a sufficient number of free addresses, a consideration if you are using a 1:1 translation as dynamic NAT or static dynamic NAT PAT greatly expands the number of translations, which you can use with a small number of addresses, so even if the addresses available on the external network is small, this method can be used. For PAT, you can even use the IP address of the mapped interface.

  

  Note If you configure the mapped interface to be any interface and you specify an address that is mapped to the same network as one interfaces mapped, then address topographiee in an ARP request for who arrives on a different interface, then you must manually configure an ARP entry for this network on the interface of penetration, by specifying its MAC address (see the arp command). Normally, if you specify an interface for the mapped interface, then you are using a single network for addresses mapped, so that this situation would not occur.

  • Addresses on a single network.

  If you need more addresses available on the mapped interface network, you can identify the address on a different subnet. The upstream router needs a static route for mapped addresses that points to the ASA. Otherwise for routed mode, you can configure a static route on the SAA for mapped addresses and then redistribute the route using your routing protocol. For transparent, if the real host is directly connected, configure the static route on the router upstream to point to the ASA: specify the IP address of the bridge group. For remote hosts in transparent mode, in the static route on the router upstream, you can also specify the IP address of router downstream.

• Administration of the ASA via IPSec VPN

  Recently, I upgraded my ASA5505 8.2.1 7.2 and curiously lost the ability to manage a VPN (via ASDM or SSH) unit. Before the upgrade, I was able to connect via a method without problem through the VPN. Internally, I still have no problem.

  The fault on the ASDM client message when I try to connect to remote is "Impossible to launch the 10.x.x.x:4444 Device Manager." If I look at the output of the console mode of information, I see later that there is a "completed by interception TCP Flow' regarding the conversation between ASA and my system remotely.

  The config lines are (I've got running on 443 webvpn):

  http server enable 4444

  255.x.x.x http inside 10.x.x.x

  http 192.x.x.x outside 255.x.x.x

  The 192 is located the beach DHCP VPN that get VPN clients (and I checked) such that these systems are able to connect to the ASDM or SSH management interface.

  Is there another ACL I need to make this work? Not sure why it worked without problem on 7.2 and as soon as I upgraded to 8.2.1, he stopped, without changing the config (manual).

  Thanks in advance for the help!

  Point VPN network ssh interface inside rather than the outside, should work, while vpn - ssh to the asa inside the ip address of the interface.
