• Disable the NAT for VPN site-to-site

  Hello world

  I work in a company, and we had to make a VPN site-to site.

  Everything works fine, except that the packages sent to my site are translated, in other words: the firewall on the other site (site_B) see only the IP address of my firewall (Site_A).

  I tried to solve the problem, but without success, I think that natives of VPN packets is the problem.

  Here is my current config running:

  Hey Houari,.

  I suspect something with the order of your NATing statement which is:

  NAT (inside, outside) static static source NETWORK_OBJ_172.19.32.0_19 destination NETWORK_OBJ_192.168.67.0_24 NETWORK_OBJ_192.168.67.0_24 NETWORK_OBJ_172.19.32.0_19

  Can you please have this change applied to the ASA:

  No source (indoor, outdoor) nat static static NETWORK_OBJ_172.19.32.0_19 destination NETWORK_OBJ_192.168.67.0_24 NETWORK_OBJ_192.168.67.0_24 NETWORK_OBJ_172.19.32.0_19

  NAT (inside, outside) 1 static source NETWORK_OBJ_192.168.67.0_24 NETWORK_OBJ_192.168.67.0_24 static destination NETWORK_OBJ_172.19.32.0_19 NETWORK_OBJ_172.19.32.0_19

  Try and let me know how it goes.

• VPN-> ASA1 < - l2l Tunnel - > client-> Service ASA2 will not work?

  Hello

  I have spent a lot of time with this problem, but I have not found a working configuration. I sound so simple, but nothing seems to work.

  We have a Site 2 Site tunnel established between two ASA 5505, in the network 'ASA2, 192.168.33.0/24' a terminal server server is located.

  A warrior of the road the VPN user connects to the network 'ASA1, 192.168.0.0/24' using the Cisco VPN Client. It is able to connect to its network services, but not the services that are found in the ASA2 network. The log file is clean, without drops.

  The client shows stats both networks secure routes.

  I'm blind for the solution, or is this not possible?

  Someone has an int for me?

  Best regards

  Markus

  Looks like you need to configure 192.168.0.0/24 within the field of encryption for the tunnel between ASA 1 with the ASA2 L2L.

  You must configure the user of warrior to also encrypt the traffic to the ASA2 network.

  You must activate the same communication intra-interface security, so that traffic can enter ASA 1, then let ASA 1 ASA 2 on the same outside the interface.

• 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.

  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.

• NATting for VPN traffic only

  I have a client with an ASA 5505 who has several networks, he tries to communicate via a VPN tunnel with a desktop remotely. One of the networks does not work because it is also used on the other side of the tunnel management interface, and none of both sides seem ready to re - IP their interior space.

  Their proposed solution is to NAT the contradictory network on this side to a different subnet firewall before passing through the tunnel. How to implement a NAT which only uses the VPN tunnel while the rest of the traffic that comes through this device of the United-NATted Nations?

  The network in question is 192.168.0.0/24. Their target you want the NAT is 172.16.0.0/24. Config of the SAA is attached.

  Hello

  Basically, the political dynamic configuration PAT should work to connect VPN L2L because the PAT political dynamics is processed before PAT/NAT dynamic configurations.

  Only NAT configurations that can replace this dynamic NAT of the policy are

  • NAT0 / exempt NAT configuration
  • Strategy static NAT/PAT
  • Public static NAT/PAT

  And because we have determined that the only problem is with the network 192.168.0.0/24 and since there is no static configuration NAT/PAT or static policy NAT/PAT, then PAT political dynamics should be applied. Unless some configurations NAT0 continues to cause problems.

  The best way to determine what rules are hit for specific traffic is to use the command "packet - trace" on the SAA

  Packet-trace entry inside tcp 192.168.0.100 12345 10.1.7.100 80

  For example to simulate an HTTP connection at random on the remote site

  This should tell us for example

  • Where the package would be sent
  • He would pass the ACL interface
  • What NAT would be applied
  • It would correspond to any configuration VPN L2L
  • and many others

  Then can you take a sample output from the command mentioned twice and copy/paste the second result here. I ask get exit twice because that where the actual VPN L2L negotiations would go through the first time that this command would only raise the L2L VPN while the second command could show already all the info of what actually passed to the package simulated.

  In addition, judging by the NAT format you chose (political dynamics PAT), I assume that only your site connects to the remote site? Given that the political dynamics PAT (or dynamic PAT) normal does not allow creating a two-way connection. Connections can be opened that from your site to the remote site (naturally return traffic through automatically because existing connections and translations)

• Rule of NAT for vpn access... ?

  Hey, putting in place the vpn ssl via the client Anyconnect on a new ASA 5510, ASA ASDM 6.4.5 8.4.2.

  I am able to 'connect' through the anyconnect client, & I am assigned an ip address from the pool of vpn that I created, but I can't ping or you connect to internal servers.

  I think that I have configured the split tunneling ok following the guide below, I can browse the web nice & quickly while connected to the vpn but just can't find anything whatsoever on the internal network.

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080975e83.shtml

  I suspect her stockings for a nat rule, but I am a bit stuck if it should be a rule of nat object network or if it must be dynamic/static & if its between the external interface or external ip & network inside or the VPN (I created the pool on a different subnet), or a 'Beach' (but then I am getting overlapping ip errors when I try to create a rule for a range of IP addresses.

  Any advice appreciated,

  Hi Eunson,

  After have connected you to the ASA that clients receive an IP address, let's say 192.168.10.0/24 pool, the network behind the ASA is 192.168.20.0/24.

  On the SAA, you would need an NAT exemption for 192.168.20.0 to 192.168.10.0

  Create two groups of objects, for pool VPN and your itnernal LAN.

  object-group network object - 192.168.20.0

  object-network 192.168.20.0 255.255.255.0

  object-group network object - 192.168.10.0

  object-network 192.168.10.0 255.255.255.0

  NAT (inside, outside) 1 source static object - 192.168.20.0 object - 192.168.20.0 destination static object - 192.168.10.0 object - 192.168.10.0 non-proxy-arp-search to itinerary

  At the inside = interface behind which is your LOCAL lan

  Outside = the interface on which the Clients connect.

  If you can't still access then you can take the shot on the inside interface,

  create and acl

  access-list allowed test123 ip host x.x.x.x y.y.y.y host

  access-list allowed test123 ip host host x.x.x.x y.y.y.y

  interface test123 captures inside test123 access list

  view Cape test123

  It will show if the packages are extinguished inside the interface and if we see that the answers or not. If we have all the answers, this means that there might be a routing on the internal LAN problem as devices know may not be not to carry the traffic of 192.168.10.0 return to the ASA inside the interface.

  Or maybe it's that there is a firewall drop packets on your internal LAN.

• Dynamic routing for VPN Failover L2L

  Hello

  Can someone offer me some advice on this please?

  I have attached a simple diagram of our EXTENSIVE referral network.

  Overview

  • The firewall is ASA 5510 running 8.4 (9)
  • Basic to the Headquarters network uses OSPF
  • On ASA static routes are redistributed into OSPF
  • On ASA for VPN static routes are redistributed into OSPF with 130 metric so redistributed BGP routes are preferred
  • Basic network has a static route to 10.0.0.0/8 to Corporate WAN, which is redistributed into OSPF
  • Branch Office WAN uses BGP - routes are redistributed into OSPF
  • The branch routers using VRRP for redundancy of the IP for the default gateway of local customers.
  • Branch router main past off VRRP IP to router backup when the WAN interface is down
  • BO backup router (. 253) contains only a default route to the internet
  • In normal operation, the traffic to and from BO uses Local Branch Office WAN
  • If local BO WAN link fails, traffic to and from the BO uses IPSec VPN via public Internet

  I try to configure dynamic routing on our network for when a branch switches to the IPsec VPN. What I want to happen (not sure if it is possible) is for the ASA announce the subnet to the remote end of the VPN in OSPF to Headquarters.

  I managed to get this working using IPP, but for some reason any VPN stay up all the time when we are not in a failover scenario. This causes the ASA added the table as a static route is the remote subnet in it and do not use the announced route of OSPF from the core network. This prevents the BO customers access to the Internet. If I remove the IPP on the VPN setting, ASA learns the route to the subnet via the WAN BO - resumes normal operation.

  I have configured the metric of the static routes that get redistributed into OSPF by ASA superior to 110. This is so that the routes redistributed by the WAN BO OSPF BGP, are preferred. The idea being that when the WAN link is again available, the routing changes automatically and the site fails to WAN BO.

  I guess what I need to know is; This design is feasible, and if so where I'm going wrong?

  Thank you

  Hi Paul,.

  your ASA maintains the tunnel alive only because this path exists on ASA.  This is why you must use IP - SLA on ASA to push network taffic "10.10.10.0/24" based on the echo response, using the ALS-intellectual property

  Please look at the example below, in the example below shows that the traffic flows through the tunnel, only if the ASA cannot reach the 10.10.10.0/24 network via the internal network of HQ.

  This configuration illuminate ASA.

  Route inside 10.10.10.0 255.255.2550 10.0.0.2 track 10

  (assuming 10.0.0.2 ip peering from inside the ip address of the router to HO)

  Route outside 10.10.10.0 255.255.255.0 xxx.xxx.xxx.xxx 254

  (value of 254 is a more expensive route to go via IPSec tunnel and x = the bridge by default-ISP)

  ALS 99 monitor

  type echo protocol ipIcmpEcho 10.10.10.254 inside interface

  NUM-package of 3

  frequency 10

  Annex monitor SLA 99 life never start-time now

  track 10 rtr 99 accessibility

  Let me know, if this can help.

• NAT before VPN - ASA L2L 8.3?

  Hello

  I have the following scenario: -.

  A net - network 172.20.82.0/24 (under my control)

  B ' net - network audience (beyond my control)

  I have a lot of servers on the Net (172.20.82.0/24) network I would PAT behind a public IP address before it is sent over a virtual private network to the remote site (Net (B). By some read far quickly, my understanding is that I'm going to need to: -.

  (a) conduct an "indoor/outdoor" PAT on the Net 'interesting' traffic to my address of PAT Public front I then...

  (b) apply the new address Public PAT crypto and ACL "NAT 0".

  i.e.

  one)

  access-list allowed NET_A_PAT 172.20.82.0 255.255.255.0 NET_B_NETWORK NET_B_NETMASK

  NAT (inside) 20 access-list NET_A_PAT

  MY_PUBLIC_PAT overall, 20 (outdoor)

  then (b)

  NO_NAT list extended access permit ip host MY_PUBLIC_PAT NET_B_NETWORK NET_B_NETMASK

  CRYPTO_MAP list extended access permit ip host MY_PUBLIC_PAT NET_B_NETWORK NET_B_NETMASK

  First question is - is it good? I think it is, but I'm just wanting clarification.

  Second question is: I is also launching a 'standard' CARESS on the 'outside' of the SAA for internet traffic normal (Internet) interface - navigation etc. If I play a PAT inside and outside as shown above, not then try and pass packets encrypted using my 'new' PAT instead of the IP Address of the remote VPN endpoint interface? Or take it to process my first PAT crypto then re - wrap by using the 'real' outside interface IP PAT?

  Hope I'm reasonably clear - thanks in advance.

  (a) correct

  (b) in part reason, crypto ACL is correct, however, you don't need NAT 0 ACL like you do a PAT.

  Second question - no, PAT comes first, then it will encrypt the packet with the IP Address of the interface that is the VPN endpoint.

• Issue of NAT for VPN

  If I have a LAN or 10.1.1.0/24 and I want NAT all of the hosts in 192.168.1.0/24.  I really don't want to create the object for each unique host network, because it's just for a lot.  I just wanted to confirm by creating two objects then natting them must configure a NAT right one?

  network object obj - 10.1.1.0

  10.1.1.0 subnet 255.255.255.0

  !

  network object obj - 192.168.1.0

  subnet 192.168.1.0 255.255.255.0

  !

  NAT (inside, outside) source static obj - 10.1.1.0 obj - 192.168.1.0 statick "remotely" destination "at a distance".

  Now when the remote network need access to network 10.1.1.0/24 hosts they should just be able to access to?

  10.1.1.1 will map to 192.168.1.1

  10.1.1.2 will map to 192.168.1.2

  10.1.1.3 will map to 192.168.1.3

  and so on...?

• Pass the authentication for applications through sqlplus scheme?

  Hello
  
  We want to change the schema of authentication for applications through sqlplus.
  
  Is it possible to do it with
  
  () www_flow_api.set_flow_authentication
  p_flow_id in the number default null,
  p_authentication in varchar2 default null);?
  
  Or will encounter us problems with this statement? Unfortunately, nothing is documented on this procedure!
  
  Thanks for any help!

  But does it work?

  Experience would give you the answer that is not.

  What is done, when I press the "make current" - button in the Application Builder? Is it the same?

  Not the same, no.

  The URL that is current when you are on the page with the button "Make Current" you tells the application and the page that does the job (4000:822). You can see that this page means when it is submitted by the consideration of this application and the page by using the f4000.sql file from distribution either by reading the code in the file, either by installing this application in your own workspace as an application ID different and using Report Builder to review the page works.

  How do you secure it, that is, who would be able to run the script?

• PAT/NAT and VPN through a PIX

  "PPTP through the PIX with Port address translation (PAT) does not work because there is no concept of ports in GRE"-this is an excerpt from a config PIX version 6.2 and below.

  1. how this problem has been fixed in 6.3? GRE is encapsulated in udp or tcp to use ports to follow the connection?

  2. is it "fixup protocol esp-ike" use the same technology - the source port created by the IKE protocol? -ISAKMP cannot be enabled when you use this command

  3. What is "isakmp nat-traversal? How is this different from fixup protocol esp-ike"

  Thank you

  RJ

  1. when the PIX sees outgoing PPTP (TCP 1723 port) packets it now opens holes for them to return, as well as opening a hole for the GRE packets, it has never done this before. The PPTP TCP packets can be PAT would be fine because they are TCP packets. GRE packets, I believe, are followed by the id field only tunnel in the package.

  2. we use the source port of the ISAKMP packet for ESP packets as well. The current limitation is that if you have this option, you cannot use the PIX to close the IPSec sessions, so you can not turn on ISAKMP any interface. You can also have only a single IPSec client internal to use this feature.

  3 NAT - T is a new standard for IPSec to work through a NAT device peers, because they detect changes of address during the negotiation of tunnel and automatically encapsulate packets in UDP 4500. This market allows the PIX and the other device (if it supports it) to automatically detect a NAT/PAT device between them. This differs from the "esp - ike correction '' that the PIX ends not in fact the IPSec tunnel with esp - ike, but it is the endpoint in nat - t.

• AnyConnect SSL VPN through IPSEC Tunnel

  Everyone was able to set up and connect using Cisco anyconnect vpn ssl on a Cisco IPSEC's tunnel. I used this in the past from a Windows XP system in the past but its not working now. None of my users are able to cooect using the Anyconnect on IPSEC. IPSEC on its own works very well.

  The Anyconnect is also able to create the connection to its ASA firewall however its not able to route all traffic through. Do you have any suggestions?

  Thanks for the update.

• This allows the customer Cisco VPN through PIX

  Hello. I seeks to allow the client VPN Cisco of LAN of the company to remote resources.

  It's put PAT in place on the PIX and I'll add the following lines to the ACL in the inside interface to allow access to the customer:

  permit tcp x.x.x.x y.y.y.y eq 50

  permit tcp x.x.x.x y.y.y.y eq 51

  permit udp x.x.x.x y.y.y.y eq 500

  permit udp x.x.x.x y.y.y.y eq 4500

  I have not done something like this before so I don't know if that will be enough to allow the connection of the client to remote resources.

  I have to do something else to make it work?

  That should be good for the local pix, but make sure that nat-traversal is enabled on the remote device.

  ESP and ah protocols, not ports. 50 and 51.

  esp x.x.x.x y.y.y.y permit

  allowed ah x.x.x.x y.y.y.y

  permit udp x.x.x.x y.y.y.y eq 500

  permit udp x.x.x.x y.y.y.y eq 4500
