NAT before going on a VPN Tunnel Cisco ASA or SA520
I have a friend who asked me to try to help. We are established VPN site to site with a customer. Our camp is a Cisco sa520 and side there is a control point. The tunnel is up, we checked the phase 1 and 2 are good. The question is through the tunnel to traffic, our LAN ip address are private addresses 10.10.1.0/24 but the client says must have a public IP address for our local network in order to access that server on local network there. So, in all forums, I see that you cannot NAT before crossing the VPN tunnel, but our problem is that our site has only 6 assigned IP addresses and the comcast router, on the side of the firewall SA520 WAN. So we were wondering was there a way we can use the WAN on the SA520 interface or use another available 6 who were assigned to the NAT traffic and passes through the tunnel. That sounds confusing to you? Sorry, but it's rarely have I a customer say that I must have a public IP address on my side of the LAN. Now, I say this is a SA520 firewall, but if it is not possible to do with who he is a way were able with an ASA5505?
Help or direction would be very useful.
Hello
I guess I could quickly write a basic configuration. Can't be sure I remember all correctly. But should be the biggest part of it.
Some of the course settings may be different depending on the type of VPN L2L connection settings, you have chosen.
Naturally, there are also a lot of the basic configuration which is not mentioned below.
For example
- Configurations management and AAA
- DHCP for LAN
- Logging
- Interface "nonstop."
- etc.
Information for parameters below
- x.x.x.x = ASA 'outside' of the public IP interface
- y.y.y.y = ASA "outside" network mask
- z.z.z.z = ASA "outside" IP address of the default gateway
- a.a.a.a = the address of the remote site VPN L2L network
- b.b.b.b = mask of network to the remote site VPN L2L
- c.c.c.c = IP address of the public peer device VPN VPN L2L remote site
- PSK = The Pre Shared Key to connect VPN L2L

NAT on 8.3 and VPN tunnel with overlapping addresses
Hi all
I was looking at this document from Cisco and I think I understand how to convert the nat policy than the version 8.3 and later, but I was wondering what is happening to the acl crypto, you are always using the same as the older versions? As you know the 8.3 then NAT requires to use the original instead of the address translated to the ACL, but I don't know if this applies to crypto ACL as well. Pointers?
Example from the link:
access-list new extended permit ip 192.168.2.0 255.255.255.0 192.168.3.0 255.255.255.0 !--- This access list (new) is used with the crypto map (outside_map) !--- in order to determine which traffic should be encrypted !--- and sent across the tunnel. access-list policy-nat extended permit ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0 !--- The policy-nat ACL is used with the static !--- command in order to match the VPN traffic for translation.
static (inside,outside) 192.168.2.0 access-list policy-nat !--- It is a Policy NAT statement. !--- The static command with the access list (policy-nat), !--- which matches the VPN traffic and translates the source (192.168.1.0) to !--- 192.168.2.0 for outbound VPN traffic.
crypto map outside_map 20 match address new !--- Define which traffic should be sent to the IPsec peer with the !--- access list (new).
Thank you

Hi rc001g0241,
I posted your question for clarity sake along.
"what happens to the crypto acl, always use you even as older versions?"
As you can see, Cisco doc you posted shows that you need to target for crypto engine is what happens after the nat policy has succeeded, illustrated here: "address match map crypto outside_map 20 new".
"As you know the 8.3 then NAT requires to use the original instead of the address translated to the ACL, but I don't know if this applies to crypto ACL as well. Pointers?
There is no such requirement and ACL target you in the engine crytop for the tunnel bound traffic can be a natted post address, that's what shows Cisco Doc and it is correct.
Hope that answers your questions.
Thank you

Client VPN und Cisco asa 5505 tunnel work but no traffic
Hi all
I am new to this forum and Don t have a lot of experience with Cisco, so I hope I can get help from specialists.
I have the following problem:
I installed und konfigured ASA 5505 for use with vpn client. I would like to access the local network from outside through vpn.
To test, I installed ASA 5505 with ADSL (pppoe) and tried to give access to the internal network.
Of course whenever I have recive the supplier's different IP address, but it didn't is not a problem reconfigure in the vpn client.
After the connection is established (vpn tunnel work) I can see my external network packets. But I Don t have any connection to the internal network.
I erased my setup yesterday and tried to reconfigure ASA again. I didn t tested yesterday, because it was too late. And I know that I Don t have the authorization rule at present by the ACL. But I think I'm having the same problem again. (tunnel but no traffic).
What I did wrong. Could someone let me know what I have to do today.
With hope for your help Dimitri.
ASA configuration after reset and basic configuration: works to the Internet from within the course.

Hello
Normally, you want a static public IP address on the ASA to allow it to receive connections from VPN clients (avoid to change the IP address all the time).
If you connect via VPN, check the following:
1. the tunnel is established:
HS cry isa his
Must say QM_IDLE or MM_ACTIVE
2 traffic is flowing (encrypted/decrypted):
HS cry ips its
3. Enter the command:
management-access inside
And check if you can PING the inside ASA VPN client IP.
4. check that the default gateway for the LAN internal ASA within intellectual property (or there is a road to the ASA to send traffic to the VPN clients).

Limit the bandwidth in the tunnel VPN on Cisco ASA
Hello
I have a site VPN tunnel to create with the local desktop client. I fear that the traffic in the tunnel in impacting the Internet bandwidth for the entire office. Is it possible to limit bandwidth on the speed VPN tunnel. I have attached a configuration that shows the configuration of the ASA at the local office.
Any help would be much appreciate. I watched QoS mapping but it's hard to make sense.
Thank you very much
Kind regards
Michael.
The ASA supported QoS features are:
Police, LLQ and Traffic ShapingTo avoid the individual flows hogging the bandwidth of the network, you can limit the maximum bandwidth used by flow (with the police)
The police is a way of ensuring that no traffic exceeds the rate (in bits per second) that you configure,
so make that person not traffic or the class can return to any of the resource.
When traffic is higher than the maximum rate, the ASA removes the excess traffic. Policy defines also the largest single burst of allowed traffic.Example of font options:
class policing_map_name hostname(config-pmap) #.
Police hostname(config-pmap-c) # {exit | entry} to compliance rates [conform burst]
[action in line [drop | send]] [action exceed [drop | send]]That is to say
HostName (config) # class - police-class card
HostName(config-CMAP) # match any
HostName(config-CMAP) # QoS_policy policy-map
class police_class hostname(config-pmap) #.
HostName(config-pmap-c) # exit police 56000 10500The configuration depends on the "this" base that you want to limit the connection.

Help with a VPN tunnel between ASA 5510 and Juniper SSG20
Hello
We have a customer wanting to configure a VPN Site to Site tunnel between a new purchased 5510 of ASA located in his direction with its Juniper SSG20 Office, located in the main office. We contacted HP and they send us a Cisco professional to do the job.
After 2 days from 16:00 to 22:00 and error and countless hours of research online and nunerous calls, we are still unable to get traffic from the network of agencies to enter the tunnel.
Main branch
1.1.1.2 1.1.1.1
----- -----------
192.168.8.0/24 | ASA|-----------------------------------| Juniper | 192.168.1.0/24
----- -----------
192.168.8.254 192.168.1.254According to Cisco professionals, the tunnel is now in place but no traffic through. We are unable to ping anything on the network on the other side (192.168.1.0/24). We receive timeout ping all the time. The Cisco professional told us it's a routing or NAT problem and he's working on a solution!
Through research, I came across a post on Experts-Exchange (here) [the 1st comment on the original post] which States "...". that both sides of the VPN must have a different class of LAN for the VPN to work... " Would that be our problem?
It has become a critical issue to the point that he had to replace the Cisco ASA with a temporary Juniper SSG5 on another subnet (192.168.7.0/24) to get the tunnel upward and through traffic until the ASA VPN issue is resolved and I didn't need to say that the client is killing us!
Help is very appreciated.
Thank you
1. Yes, ping package from the interface of the ASA is considered valuable traffic to the LAN of Juniper.
SAA, need you traffic from the interface source ASA's private, because interesting to determine by crypto ACL MYLIST traffic between 192.168.8.0/24 and 192.168.1.0/24.
You will also need to add the following configuration to be able to get the ping of the interface of the ASA:
management-private access
To initiate the ping of the private interface ASA:
ping 192.168.1.254 private
2. the default time before the next generation of new key is normally 28800 seconds, and if there is no interesting traffic flowing between 2 subnets, he'll tear the VPN tunnel down. As soon as there is interesting traffic, the VPN tunnel will be built automatically into the next generation of new key. However, if there is traffic before generating a new key, the new tunnel will be established, and VPN tunnel will remain standing and continue encrypt and decrypt traffic.
Currently, your configuration has been defined with ITS lifetime of 3600 seconds GOLD / 4608000 kilobytes of traffic before the next generate a new key (it will be either 3600 seconds, or 4608000 kilobytes period expires first). You can certainly change it by default to 28800 seconds without configuring kilobytes. SA life is negotiated between the ASA and Juniper, and whatever is the lowest value will be used.
Hope that helps.

2 VPN tunnels on ASA common; A PRI a BKP at the same address-end peer
Hi all
I have an ASA 5505 branch that has 2 circuits ISP. I have a data center ASA who has 1 ISP circuit. I have a VPN tunnel between the primary circuit ASA branch and the ASA circuit data center. I would like to implement the ASA branch for the redundancy of the SLA so I can use primary and backup circuits, but two configs tunnel going to the same address-end peer, since the data center has only 1 ASA. I read that an ASA cannot have several tunnels to the same peer address because the ASA may have 1 SA by peer address.
However, if I have my branch ASA configured for redundancy of the SLA, then only 1 tunnel would at once, which I think would affect the requirement of SA above.
Can someone tell me if this is possible?
Thank you.
Hi Dean,
You're right about things als because only link will be active at a time.
On the ASA branch, you can apply the same encryption card to two primary and secondary circuit. You use just ALS to determine how this ASA branch will reach the address of peer card crypto (IP addr of ASA Data Center).
I wrote an article about a similar scenario here: http://resources.intenseschool.com/using-vpn-tunnels-as-backup-links-primary-and-backup-vpn-tunnels-on-cisco-asa/

I managed to configure the two so that the vpn connects. Each of the firewall I ping the IP Address of the internet firewall on the other side and a desktop computer I can ping the IP Address of the firewall internal datacenter but I can't carry traffic between private subnets datacenter and desktop. Can anyone help?

I have two Cisco ASA 5510 firewall with a similar setup configuration and the AnyConnect SSL VPN works great.
Hi Matt,
You are probably landing on the tunnel-group by default - you will need to indicate which group to connect to the client. This can be done in different ways - I see that you already have a defined group aliases, but to be able to use that you must configure:
WebVPN
tunnel-group-list activate
Alternatively, if you have only a single group, you can add 'group-url https://yourasa.yourcompany.com/ permit' to the webvpn attributes tunnel-group.

IPSec VPN between Cisco ASA and Fortigate1000
Hello
I find a useful document on how to create a tunnel VPN IPSec with ASA 5510 firewall Fortigate 1000...
the configuration of the coast FG is done without any problem, BUT the document (. doc FG) said I must configure the ASA with a GRE interface and assign an internal IP address in order to communicate with the FG...
The question is: How do I configure the interface on the SAA ACCORD?
Thanks in advance, Experts...
Kind regards...
ASA firewall does not support the interface/GRE GRE tunnel.
If you need to have GRE configured, you will need to complete the GRE tunnel on router IOS.
If you want to configure just pure tunnel VPN IPSec (lan-to-lan), here is an example of configuration on the side of the ASA:
http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080950890.shtml
Hope that helps.

Cisco VPN 3060 - Cisco ASA conversion
We are about to embark on the passage of all extensions L2L and network (Cisco ASA 5505 s) of the Cisco VPN 3060 concentrator to a Cisco ASA 5520.
We bsemblable woul to see if there is a simple method to do this as a converter? Also, there are lessons learned? We run 8.4.3 so that we know that the NAT configuration has differed. The 3060 configuration can be changed in anyway for help in configuring the ASA?
Thank you

Thank you for your understanding Dwane.

Hello
I'm trying to get my ipad to VPN to our Cisco ASA5520.
I think I have all the correct settings on both ends (I am able to vpn to the asa using a cisco 871 as the remote client).
I think that for some reason the client vpn on ipad is not even make the asa. My question is: How can I monitor the ASA logs to see if the same connection attempt and eventually find the failure?
Thank you
M
try: -.
Debug crypto ISAKMP
Debug crypto ipsec
Vpn-sessiondb SH remote control (to see if the client is connected)
I have configured ipad for remote vpn client, the user could connect to the 5520 but why that I had to use the ip addresses to access, but I couldn't use internal dns names. try to understand that at this moment.
It may be useful

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

Profile VPN (tunnel group) under the same IP pool
Hello
I have on my clients VPN from Cisco ASA 5510 works perfectly. The thing is that now I want to create a new profile or a tunnel in order to create the new cause of ACL I want to restrict only to certain hosts. But I don't know if I can do it under the same IP pool. If the answer is yes how could bind the new tunnel group to the correct ACL.
This is my config:

The command is "vpn-filter" in the Group Policy section.
Define a group policy for each group of tunnel and select it with 'by default-group-policy' in the section of the tunnel.
