• VPN L2L ASA with NAT

  Hello, I was hoping someone might have an example of a site to site VPN configuration where the ASA is statically NATting its internal network. Basically the same configuration like this, but instead of "not nat", the ASA is NATting. So instead of the remote site, connect to the local network 10.10.10.0/24, ASA would be NAT at 172.16.17.0/24 for example.

  http://www.Cisco.com/en/us/products/ps9422/products_configuration_example09186a0080b4ae61.shtml

  Thank you.

  Mike

  It's not very complicated, just keep in mind that NAT is done before the encryption.

  So if you your network 10.10.10.0/24 nat internal to 172.16.17.0/24:

  public static 172.16.17.0 (Interior, exterior) 10.10.10.0 netmask 255.255.255.0

  You can use the address translated into your crypto-ACL:

  REMOTE VPN ip 172.16.17.0 access list allow REMOTE-NET 255.255.255.0 255.255.255.0

  I suppose that you run ASA v8.3 + that you referred to an older document. If you have a more recent software, the logic is the same but the NAT commands differ.

• Policy NAT for VPN L2L

  Summary:

  We strive to establish a two-way VPN L2L tunnel with a partner. VPN traffic is one-to-many towards our partner, and our partner they need of a many-to-one to us (they need to access a host on our network). In addition, our partner has many VPN, so they force us to use a separate NAT with two private hosts addresses, one for each direction of the tunnel.

  My initial configuration of the tunnel on my grown up side of Phase 1, but not IPSec. Partner ran debug that revealed that my host did not address NAT'd in the NAT policy. We use an ASA5520, ver 7.0.

  Here is the config:

  # #List of OUR guests

  the OURHosts object-group network

  network-host 192.168.x.y object

  # Hosts PARTNER #List

  the PARTNERHosts object-group network

  network-host 10.2.a.b object

  ###ACL for NAT

  # Many - to - many outgoing

  access-list extended NAT2 allowed ip object-group OURHosts-group of objects PARTNERHosts

  # One - to - many incoming

  VIH3 list extended access permit ip host 192.168.c.d PARTNERHosts object-group

  # #NAT

  NAT (INSIDE) 2-list of access NAT2

  NAT (OUTSIDE) 2 172.20.n.0

  NAT (INSIDE) 3 access-list VIH3

  NAT (OUTSIDE) 3 172.20.n.1

  # #ACL for VPN

  access list permits extended VPN ip object-group objects PARTNERHosts OURHosts-group

  access allowed extended VPN ip host 192.168.c.d PARTNERHosts object-group list

  # #Tunnel

  tunnel-group type ipsec-l2l

  card <#>crypto is the VPN address

  card crypto <#>the value transform-set VPN

  card <#>crypto defined peer

  I realize that the ACL for the VPN should read:

  access allowed extended VPN ip host 172.20.n.0 PARTNERHosts object-group list

  access allowed extended VPN ip host 172.20.n.1 PARTNERHosts object-group list

  .. . If the NAT was working properly, but when this ACL is used, Phase 1 is not even negotiating, so I know the NAT is never translated.

  What am I missing to NAT guests for 172.20 addresses host trying to access their internal addresses via the VPN?

  Thanks in advance.

  Patrick

  Here is the order of operations for NAT on the firewall:

  1 nat 0-list of access (free from nat)

  2. match the existing xlates

  3. match the static controls

  a. static NAT with no access list

  b. static PAT with no access list

  4. match orders nat

  a. nat [id] access-list (first match)

  b. nat [id] [address] [mask] (best match)

  i. If the ID is 0, create an xlate identity

  II. use global pool for dynamic NAT

  III. use global dynamic pool for PAT

  If you can try

  (1) a static NAT with an access list that will have priority on instruction of dynamic NAT

  (2) as you can see on 4A it uses first match with NAT and access list so theoretically Exchange autour should do the trick.

  I don't see any negative consequences? -Well Yes, you could lose all connectivity. I don't think that will happen, but I can't promise if you do absolutely not this after-hours.

• Configuration of VPN Cisco RV220W wireless

  Hello expert support.

  We have a RV220 Wireless Network Security Cisco Firewall.  It is currently configured to provide access only to select users.  Asked me to configure it to provide access to users of hotspots or home networks.  Thought which is on the road, or at home that they would use their home network or a location of hot point to the VPN to the RV220 to access the documents they needed.

  My hypothesis was set up VPN with the users who access the QuickVPN client.  I followed the setup steps, but VPN access failed.

  Anyone who has tried or succeeded in a configuration like that?  I have read a number of posts with users having problems, just configure the VPN and access with QuickVPN.

  Any help would be greatly appreciated.

  Best regards

• Direct specific ports down a VPN L2L

  I have a client who is trying to use an ISP hosted web filtering and content management a gateway, the ISP wants to use and L2L ISPEC VPN on site at their front door to control the traffic. Today we have the tunnel with an ACL test for peripheral test side customer down the tunnel, but that it blocks all traffic that is not being analyzed. The problem is that they are on an ASA 5510 with 8.2.2. You cannot add ports tcp in the ACL sheep, it error when you try to apply the nat 0 access-list statement sheep (inside). We can define the ports to go down the VPN traffic interesting ACL with number, but there is no way to send just the web ports down the VPN and allow the other ports on regular overflow interface NAT I was look in 8.4 and see if it allows a policy NAT (twice the NAT for virtual private networks) to set a port to a range of IPS (IE (: nat static destination WEBINSPECT-WEBINSPECT (indoor, outdoor) static source a whole) but who only define as web ports.

  I do not have an ASA test to use, but I guess that vpn l2l will be only by IP and I can not define a port tunnel.

  In any case, it is a strange, but the ideas are welcome. I don't think it's possible, but I thought I'd see if anyone encountered at the front.

  Hello

  Well to give you a simple example where we use the double NAT / manual transmission NAT to handle traffic

  For example a configuration example I just did on my 8.4 (5) ASA

  The following configuration will

  • Set the 'object' that contains the source network for NAT
  • Set the 'object' that contains the service for NAT
  • Define the real NAT

  The real NAT is going to make any connection from the network under 'Wireless' network object to the destination port TCP/80 will be sent 'WAN' interface without NAT

  Of course it is the next step with VPN L2L network under 'network wireless of the object' would correspond to the ACL of VPN L2L. But that seemed straight forward for you already

  the subject wireless network

  10.0.255.0 subnet 255.255.255.0

  service object WWW

  Service tcp destination eq www

  NAT (WLAN, WAN) static source without WIRE WIRELESS WWW WWW service

  The following configuration will

  • Define the "object-group", that defines networks of the source of the rule by default PAT for Internet traffic
  • Set the 'object' for the PAT address (could just use 'interface' instead of the 'object')
  • Define the real NAT

  The NAT configuration will just make a rule by default PAT for the wireless network. The key thing to note here is that we use the setting "auto after." This basically inserts the NAT rule to the priority of the very bottom of the ASA.

  object-group, network WIRELESS-network

  object-network 10.0.255.0 255.255.255.0

  network of the PAT object - 1.1.1.1

  host 1.1.1.1

  NAT (WLAN, WAN) after the automatic termination of wireless - NETWORK PAT dynamic source - 1.1.1.1

  Now we can use the command "packet - trace" to confirm that the NAT works as expected.

  Hello

  1. you create a second access as list:

  outside_cryptomap ip 172.18.138.0 access list allow 255.255.255.0 172.18.133.0 255.255.255.0

  and

  2. instead of

  correspondence address 1 card crypto transam 101

  You must configure

  card crypto transam 1 match address outside_cryptomap

  the problem is that you configure an ACL for nat and crypto - that does not work

• Redirect peer tunnel VPN L2L ina

  Question of curiosity... I have 2 new ASA5515 which I put up for an improvement of the equipment. In the time before I swap them I am using them as a sort of laboratory of fortune to get him going to setup VPN L2L. I didn't use current IP addresses for the test environment, so I used false numbers.

  My question is: can I go back and change the IP address peer and address local/remote without having to tear them up to specifications plant again?

  -Do I have reprint just the type of Tunnel-Group IPsec-l2l X.X.X.X command with the IP address?

  I know that there are a few other of the region that I have to change the IP of both peers, but just of my question is, I can do or do I have to start over?

  -Jon

  Jon

  You should not reconfigure from scratch if that's what you're asking.

  You just need to change the peer IPs everywhere where they appear in your configuration.

  isakmp policy number and the number of ipsec policy do not match your ASA or with the other end. They are two distinct phases of negotiation. The ASA will compare your policy at the other end, starting with the smallest number of policies, until a match is found.

  I usually put safer policies first (i.e. with the lowest number of the police).

  To create a new policy, just add it with a new policy number, anywhere where you want in the order.

  So if your host 'inside' is 192.168.1.2 and the 'outside' host is 10.10.1.2 then you could just what follows

  Packet-trace entry inside tcp 192.168.1.2 12345 10.10.1.2 80

  If the goal is just to test the VPN negotiation then the ports are not really important, but naturally tested traffic with "packet - tracer" must be authorized by your interface "inside" ACL.  The essential is that the source address and destination match the VPN L2L (Crypto ACL) configurations

  Generally you would use NAT0 for these networks the and remote so NAT should not be a problem to test from that direction. I suppose there might be rare situations where using the command in this sense is not possible

• Outgoing NAT does not not for a VPN L2L

  We have an ASA5510 which has two LAN to LAN IPSEC VPN configured.  VPN tunnels themselves are on the rise and a VPN works great.  But the other VPN is not working properly the outgoing NAT traffic (inbound is very well of all the VPN endpoints).  When I ping from the ASA using 'ping inside the 10.200.4.x', it works.  When I ping from a box sitting inside the subnet I get the following error in the ASA logs:

  failed to create translation portmap for udp src inside:10.26.32.2/137 dst outside:10.200.4.x/137

  I would really appreciate if someone could tell what I did wrong with the NAT or routing configuration. This is the first time I setup two L2L VPN on a SAA.  The relevant parts of the configuration below, are properly anonymized.

  Edit: I forgot to mention that, once it works I need then for the inbound NAT to web.server.public.ip to 10.26.32.2 and add ACL entries for www and https.

  Thank you

  These 2 lines are incorrect. The list of access crypto-list and you should not only applied to the NAT statement.

  NAT (inside) 0-list of access outside_1_cryptomap_1

  NAT (inside) 1 access-list outside_20_cryptomap_1

  Please remove the 2 statements of NAT above, but keep the access list because those that are applied to the card encryption.

  Then you must configure the following:

  10.26.32.0 IP Access-list extended sheep 255.255.255.0 allow 192.168.0.0 255.255.0.0

  IP 10.26.32.0 allow Access-list extended sheep 255.255.255.0 10.200.4.0 255.255.255.0

  NAT (inside) 0 access-list sheep

  Once the changes above, pls make "clear xlate.

  Hope that helps.

• 1841 as Concentrator VPN remote access with manual keying

  Hi there and happy new year 2011 with best wishes!

  I would use a router 1841 as VPN hub for up to 20 remote connections.

  My remote (third party) clients have IPsec capacity supported by IKE and the Manual Keying, but I have not found information about simple configuration of Cisco VPN remote access (only on the easy VPN server).

  I'd like to configure the VPN entry Server Manual (I think it's an easy way to start), no problem to do?

  files:

  -topology

  -third party router Ethernet / 3G GUI IPsec with choice of algorithm auth

  -third party router Ethernet / 3G GUI IPsec with choice of encryption algorithm

  I feel so much better that someone help me!

  Kind regards

  Amaury

  As the remote end is third-party routers, the only option you have will be LAN-to-LAN IPSec VPN. You can not run VPN easy because that is only supported on Cisco devices.

  If your remote end has a static external ip address that ends the VPN, you can configure card crypto static LAN-to-LAN on the 1841 router, however, if your remote end has dynamic external ip address, you must configure card crypto dynamic LAN-to-LAN on the 1841 router. All remote LAN subnets must be unique.
