NAT and VPN site-2-Site
Hello world.
I have question about Site 2 Site VPN and NAT.
HQ is connected to the partner and the co-location through site to site VPN (with two different tunnels). Co-location is connected to the HQ with the site 2 site VPN.
HQ:
Co-location:
Partner:
Basically, what I want to achieve is to do the following:
All traffic from the combination with destination partner should switch from AC and source what IP must be changed. So it seems that the traffic originated in the DMZ HQ on the side of the partner.
How can I achieve that?
HW: Cisco ASA
Hello Roger,.
The configuration you need will be on the ASA HQ.
First configure the ASA so that it would allow the traffic to leave through the same interface it came through:
permit same-security-traffic intra-interface
Then, you create a nat that an IP address of this beach (it will work if the partner does not need to go to the apartment, just camp to the partner):
policy-based-nat1 permit ip access list
NAT () to access list policy-based-nat1
(Global)
That is asuming that you already have a rule of traffic interesting (crypto ACL map) allowed your DMZ for flatsharing.
For a more specific example, see below:
Colocation network: 192.168.1.0/24
Network DMZ HQ: 10.10.10.0/24
Network partner: 172.16.10.0/24
permit same-security-traffic intra-interface
access list policy-based-nat1 permit ip 192.168.1.0 255.255.255.0 172.16.10.0 255.255.255.0
NAT (outdoor) 100 access list policy-based-nat1
global (outside) 100 10.10.10.253
vpn10 10.10.10.0 ip access list allow 255.255.255.0 172.16.10.0 255.255.255.0
10 correspondence address vpn vpn crypto card
If the partner needs to access the apartment so (two-way access) you may not use the DMZ network as there must be a translation from one to the other and you have the same amount of addresses to be translated you have on the apartment.
However, it would be possible if your DMZ network is greater than the apartment (like DMZ being a 16 and colo in 24) and you can isolate a subnet just for NAT.
Hope this helps to solve the problem.

Static NAT enable VPN site-to-site.
Hello
We plan to build VPN site to site, but, we have a single public routerable internet IP address to assign VPN on Site A, but Site B is ok.
in this case, I think that we must use static NAT on the router, the simple diagram is as below.
internal a subnet - router VPN - router for Internet of the Site - to - VPN - B B Site internal subnet.
the final goal is to make the communication between internal a subnet and subnet B on IPSEC tunnel.
OK, as I said, Site A having a public IP address, then it must use the static NAT and need to apply on the Site router.
Router
interface x/x
Head of ESCR to the internet
NAT outside IP
!
interface x/x
Head of DESC to internal (VPN)
IP nat inside
!
IP nat inside source static (like IP address x.x.x.x) public (as private VPN interface IP x.x.x.x)
so, wouldn't be work without any problem? I think it will work, but I would find other one just in case.
Hey,.
Is that what you try to achieve:
subnet A - A = vpn router = router B - Sub-B network
and you need communicate between Subnet A and subnet via ipsec vpn b?

ASA 8.4 (1) source-nat over vpn site-to-site
I'm setting up a tunnel vpn site-to-site and require nat for the local and remote side. The remote side will be nat to
10.2.255.128/25 on their face before they reach our network, so I have to only source-nat our servers via the tunnel to them. Should I just do the static NAT, then let the whole subnet through the acl of valuable traffic as the config below? I don't think I should use twice a nat because I'm not trying to make the destination nat on the firewall. Servers with us will 10.2.255.128/25 and I would like to preserve it through the ASA.

Thank you
Your configuration is correct, but I have a few comments. Remember that NAT occurs before the delivery of your servers will be translated into 10.2.255.2 and 10.2.255.3 and then sent through the tunnel, so your encryption field is correct.
Is your internet firewall as well? What your servers out of the internet? They will be translated to 10.2.255.2 and 10.2.255.3 and who will fail in internet routing is. If these servers access the internet through the firewall, I would recommend a configuration like this for each of your servers:
network of the ServerA_NAT object
Home 10.2.255.1
NAT static ServerA ServerA_NAT destination (indoor, outdoor) static source REMOTE_SUBNET REMOTE_SUBNET
This will use destination basic NAT for traffic VPN and NAT everything to a public IP address for the internet traffic. Of course, if this is not your internet connection firewall can do abstraction.

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

Try and let me know how it goes.
If she did not help, please put the output form a package tracer will shape your internal network to the remote VPN subnet with the release of «see the nat detail»

IP common in client IPSec VPN and VPN site to site
Hello
We have a scenario where the Cisco ASA 5505 will be one of the ends of a site to site VPN. The same ASA 5505 also allows the Client VPN connection. The issue is around the pooling of intellectual property.
If I assign a pool of IP addresses (192.168.1.20 - 192.168.1.30) for connections VPN Client - do I need to be sure that these same IP are not used across the site to site VPN?
There may be a PC / servers running 192.168.1.0/24 on the other side of the site to site VPN. This would lead to an address conflict?
"
I have attached a diagram of the scenario. I would like to know if the 'orange' PC would cause an IP conflict if they get the same IP that PC "blue color" - even if one of them is the VPN client and the other is VPN site-to-site
Thank you.
Altogether. The pool of the VPN Client must be single subnet which is not anywhere within your network.

Hello
I have asa 5512-x
ASA 9.1 version 2
ASDM version 7.2 (1)
I'm not really good with a syntax of cisco, so I use asdm
I created a split tunnel remote ipsec vpn with cisco vpn client
the purpose is to allow vpn for LAN traffic
and to allow the vpn to a public Web site traffic
so I set the two objects and added to the exemption of split tunnel (the names of the objects: 'LAN', 'Rackspace')
access to the local network is ok, access to a Web site does not work
I guess I have some missing nat/ACL,
can someone explain to me please in the most simple way to do this?
Thank you very much
Hello
What is subnet
network of the NETWORK_OBJ_172.18.0.0_26 object
255.255.255.192 subnet 172.18.0.0This 'nat' configuration seems strange
NAT (LAN, WAN1) source static Tunnel VPN VPN Tunnel static destination NETWORK_OBJ_172.18.0.0_26 NETWORK_OBJ_172.18.0.0_26 non-proxy-arp-search to itinerary
When you see that the source for the "nat" interface is 'LAN' and source networks are those configured under "Tunnel VPN" it seems to suggest that this NAT configuration transmits traffic destined to 'LAN' and 'rackspace' to the 'LAN' interface. It is naturally very good for the subnet configured under 'LAN' , but the 'rackspace' to my knowledge is located behind an external interface of the ASA correct? But I guess I really need to know this as the subnet that I mentioned at the beginning of the post (which is used in this configuration NAT too)
What is the interface to which the VPN users connect to? WAN1 or DSL? Although the following list what the map interface Crypto is attached
See the crypto run map
You can also list the output of the following command

Access to services: conflict NAT and VPN
Hi people!
I encountered a problem with external access to local services of:
(a) remote clients (port open on the side WAN)
(b) the remote sites (through IPsec tunnels)Here's a topology:
EXPLANATIONS
FW1 (actually from TMG 2010) overload NAT of preforms.
The service in question (for example tcp 9999) is published on 192.168.100.0/24 via static NAT translation, which is accessible from the network.
HQ1 is a border router (cisco 2921). It also performs NAT overload for public addresses. (Other than cisco) Branch1 also performs NAT overload.
All traffic between the headquarters and the remote site is allowed. The service is accessible from the remote site.
PROBLEM
I want to allow access to the service for an external user (remote user). I do the following configuration:
IP nat inside source static tcp 192.168.100.2 2.2.2.2 9999 9999 extensible
After this command remote user is able to access the service by public IP, BUT the site's users remote losing it. If I roll back with
No nat ip inside the source static tcp 192.168.100.2 2.2.2.2 9999 9999 extensible
then access to the remote site is restored, and remote user lose again. Seems that it is connected with the static NAT translations.
How can I make it work in both cases of simulteniously? Both for the remote site and the remote user.
Thank you!
You must use a map of the route with your static NAT configuration.

Help without NAT and VPN Config DMZ.
Before VPN, we miss with 'nonatdmz '. Recently, we tried to implement the solution VPN using "VPNRA".
ASA IOS would only you are using a "NAT 0" at a time, how do you get around that.
TIA
nonatdmz list of allowed ip extended access any 192.168.100.0 255.255.255.0
NAT (inside) 0-list of access nonatdmz

You can add several lines to you nonatdmz access-list: for example:
nonatdmz list of allowed ip extended access any 192.168.100.0 255.255.255.0
access extensive list ip 172.0.0.0 nonatdmz allow 255.0.0.0 10.17.70.0 255.255.255.0

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.

The sequence number of card crypto for the static mapping crypto (site to site vpn) should be higher (ie: sequence number must be lower) than the ezvpn (map dynamic crypto).
In your case, you must configure as follows:
map easyvpn 10 ipsec-isakmp crypto
defined by the peers (deleted)
Set transform-set vpn
game site addressmap easyvpn 150 - ipsec-isakmp crypto dynamic easyvpn
Hope that solves this problem.

Router vpn site to site PIX and vpn client
I have two on one interface on the pix vpn connections that terminate VPN. client vpn and VPN site-to-site have passed phase one and two and decrypt and encrypt the packets. However as in another post I can not ping through the l2l vpn. I checked this isn't a nat problem a nd two NAT 0 on the pix and the NAT on the router access lists work correctly.

However when I test the connection I did not enter any of the static routes that networks are connected directly on each side of the pix and the router. any help would be a preciated as I think there's maybe something is blocking the ping to reach the internal network at the end of pix with a configured access list.
is ping failure of the only thing between the site to site VPN? and assuming that all other traffic works fine since it decrypts and encrypts the packets.
If it's just ping, then activate pls what follows on the PIX:
If it is version 6.3 and below: fixup protocol icmp
If it is version 7.0 and higher: select "inspect icmp" under your political map of the world.
Config complete hand and on the other could help determine if it's a configuration problem or another problem.

VPN site to Site IDLE-UP and no traffic...
Hello
I have two Office (hand and brach) each with a router cisco 887 15.3 with s + ios k9
I have configured the vpn client (works without any problem at all) and a site to site VPN.

I'm not for some without seeing a cry of debugging IPsec, but I think you can be matching your dynamic map first with a seq of 10. I would try delete and assigning to 100 or something on both sides. Disable sessions and try again.

Cisco ASA VPN Site to Site WITH NAT inside
Hello!
I have 2 ASA 5505 related to IPSEC Tunnel VPN Site to Site.
A 192.168.1.0/24 'remotely' inside the network and a local "192.168.200.0/24' inside the network (you can see the diagram)
The local host have 192.168.200.254 as default gateway.
I can't add static route to all army and I can't add static route to 192.168.200.254.
NAT the VPN entering as 192.168.200.1 or a 192.168.200.x free to connect my host correcly?
If my host sends packet to exit to the default gateway.
Thank you for your support
Best regards
Marco
The configuration must be applied on the SAA with the 192.168.200.0 subnet it is inside, there must be something like this:
permit 192.168.1.0 ip access list VPN_NAT 255.255.255.0 192.168.200.0 255.255.255.0
NAT (outside) X VPN_NAT outside access list
Global (inside) X Y.Y.Y.Y (where the Y.Y.Y.Y) is the ip address
If you have other traffic on the vpn through the tunnel that requires no nat, then you must add external nat exemption rules since these lines above obliges all traffic through the asa to have a nat statement.
See if it works for you, else post your config nat here.

Tunnel VPN remote Internet and VPN remote VPN from Site to Site traffic?
Hello
We try to remote traffic from our users VPN tunnel through our ASA 5510 as well as to allow the only access for remote user VPN traffic to the other end of the all our VPN site-to-site connected to the same ASA. Basically, we who want to VPN in the network in order to access all of our networks business. We try to get away with this without using split Tunneling.
I can currently get internal traffic from the remote user VPN to reach all other vpn site-to-site tunnels without the internet in tunnel. The problem is when I add the following statement to the NAT:
NAT (outside) 1 10.10.19.0 255.255.255.0 * 10.10.19.0 is the address of the remote VPN Client
Internet traffic to the remote VPN starts to get in the tunnel, but I lose the opportunity to reach one of the other tunnels from site to site by the remote VPN tunnel.
I also begin to receive the following errors in the journal of the ASA
3 July 1, 2009 12:34:18 305005 10.10.19.255 137 no group of translation not found for udp src outside:10.10.19.3/137 dst outside:10.10.19.255/137
Any help with how NAT statements must be defined for this work would be appreciated.
Thank you

Will,
the link of this post for your scenario of vpn hub & speak reference, you problem may be on exempt nat rules.
Have a second look at your sheep rules.
Be sure to eliminate tunnel rules related to rheumatoid arthritis, as appropriate, to not let him get in the way of splitting.
If always emits discribe topology for l2ls and info logic RA and sanatized hub config asa... but I think if you look at the thread above, you should be able to solve.
