VPN NAT help

I need to configure NAT on a VPN tunnel to accomplish the following. I already have the tunnel upward and running just need to confirm my NAT config.

ASA 8.2 Version running (5)

I only need to set up A

The internal subnet to site A is 172.30.6.0/24 and I need NAT this subnet to 172.31.183.0/24 when the destination subnet is 172.31.255.128/25

So here's what I thought.

Policy NAT 172.30.6.0/24 to 172.31.183.0/24 the translation when the destination is 172.31.255.128/25.

Public static 172.31.183.0 (inside, outside) - CBC-NAT-TRANSLATION access list

CBC-NAT-TRANSLATION scope ip 172.30.6.0 access list allow 255.255.255.0 172.31.255.128 255.255.255.128

Then I would need that

Public static 172.31.255.128 (exterior, Interior) 172.30.6.0 netmask 255.255.255.0

That sounds about right.

Thank you

As I said that I did not use a network with a static NAT strategy, so I don't know if the host part of the IP address matches the host Party in the range NAT if you see what I mean.

It could, but it cannot be a concern for you anyway. You would need to watch the xlate table once you make the connection to know for sure.

In addition, it means all devices in this subnet may send packets to each device in the remote subnet but once again can not be a cause for concern.

But apart from that, Yes, your config seems fine for me.

I try with the first beach and establish a connection and then if it works check the xlate dashboard to see exactly what IP he chose.

  • Need help to configure VPN NAT traffic to ip address external pool ASA

    Hello

    I need to configure vpn NAT ip address traffic external pool ASA

    For example.

    Apart from the ip address is 1.1.1.10

    VPN traffic must be nat to 1.1.1.11

    If I try to configure policy nat or static nat ASA gives me error "global address of overlap with mask.

    Please, help me to solve this problem.

    Thank you best regards &,.

    Ramanantsoa

    Thank you, and since you are just 1 IP 1.1.1.11 Polo, the traffic can only be initiated from your site to the remote end.

    Here is the configuration of NAT:

    access list nat - vpn ip 192.168.1.0 allow 255.255.255.0 10.0.0.0 255.255.0.0

    NAT (inside) 5 access list nat - vpn

    Overall 5 1.1.1.11 (outside)

    In addition, the ACL crypto for the tunnel from site to site should be as follows:

    access-list allow 1.1.1.11 ip host 10.0.0.0 255.255.0.0

    Hope that helps.

  • Site to Site VPN of IOS - impossible route after VPN + NAT

    Hello

    I have problems with a VPN on 2 routers access 8xx: I am trying to set up a quick and dirty VPN Site to Site with a source NAT VPN tunnel endpoint. This configuration is only intended to run from one day only inter. I managed to do the work of VPN and I traced the translations of NAT VPN tunnel endpoint, but I couldn't make these translated packages which must move outside the access router, because intended to be VPN traffic network is not directly connected to leave the router. However, I can ping the hosts directly connected to the router for access through the VPN.

    Something done routing not to work, I don't think the NATing, because I tried to remove the NAT and I couldn't follow all outgoing packets that must be sent, so I suspect this feature is not included in the IOS of the range of routers Cisco 8xx.

    I'm that extends the features VPN + NAT + routing too, or is there a configuration error in my setup?

    This is the configuration on the router from Cisco 8xx (I provided only the VPN endpoint, as the works of VPN endpoint)

    VPN endpoints: 10.20.1.2 and 10.10.1.2

    routing to 192.168.2.0 is necessary to 192.168.1.2 to 192.168.1.254

    Hi Jürgen,

    First of all, when I went through your config, I saw these lines,

    !

    interface Vlan2

    IP 192.168.1.1 255.255.255.248

    !

    !

    IP route 192.168.2.0 255.255.255.0 192.168.1.254

    !

    With 255.255.255.248 192.168.1.1 and 192.168.1.254 subnet will fall to different subnets. So I don't think you can join 192.168.2.0/24 subnet to the local router at this point. I think you should fix that first.

    Maybe have 192.168.1.2 255.255.255. 248 on the router connected (instead of 192.168.1.254)

    Once this has been done. We will have to look at routing.

    You are 172.31.0.2-> 192.168.1.11 natting


    Now, in order for that to work, make sure that a source addresses (192.168.1.11) NAT is outside the subnet router to router connected (if you go with 192.168.1.0/29 subnet router to router, with 192.168.1.1/29 on the local router and 192.168.1.2/29 on the connected router as suggested, it will be fine). So in this case 192.168.1.8/29 to the subnet that your NAT would be sources fall.

    Have a static route on the router connected (192.168.1.2) for the network 192.168.1.8/29 pointing 192.168.1.1,

    !

    IP route 192.168.1.8 255.255.255.248 192.168.1.1

    !

    If return packets will be correctly routed toward our local router.

    If you have an interface on the connected rotuer which includes the NAT would be source address range, let's say 192.168.1.254/24, even if you do your packages reach somehow 192.168.2.0/24, the package return never goes to the local router (192.168.1.1) because the connected router sees it as a connected subnet, so it will only expire

    I hope I understood your scenario. Pleae make changes and let me know how you went with it.

  • Networks VPN NAT l2l problem-Dup-HELP!

    I use a router IOS as a VPN L2L device to connect my site to several different customer locations, some of them use the same internal IP addresses.  These VPNS have been working well.

    I recently added another client to this system and I am now having a problem with the new configuration.  With this configuration, I have NAT my internal addresses.  NAT works correctly, but it NAT my bad common NAT addresses and therefore do not generate the tunnel.

    My internal IP 10.10.x.x

    incorrect NAT pool 10.129.x.x

    decent NAT pool 10.99.x.x

    Help... :))

    Thank you

    The problem is simple. You have almost an identical ACL for two guests. As the first NAT rule has been added previously, it comes into play. To resolve this issue, you must set explicit host/subnet destination match instead of 'none' keyword.

    For example like this:

    ip access-list extended ME-CRYPTO-ACL

      permit ip 10.129.40.0 0.0.0.255 host 10.10.131.63

    ip access-list extended ME-NAT-ACL

      permit ip 10.10.10.0 0.0.0.255 host 10.10.131.63

    ip access-list extended SA-CRYPTO-ACL

      permit ip 10.96.21.0 0.0.0.255 host 10.99.2.95

    ip access-list extended SA-NAT-ACL

      permit ip 10.10.10.0 0.0.0.255 host 10.99.2.95

    Another solution is more complex and harder to understand (and explain), you can use Virtual models with tunnel-protection for each customer, VRF and NAT for common services.

  • ASA L2L VPN NAT

    We have a partner that we set up a VPN L2L with.  Their internal host IP infringes on our internal IP range.  Unfortunately, they are not offer NAT on their side.  Is it possible on the SAA to configure a NAT device for my internal hosts will say 1.1.1.1 and ASA changes the internal address of the remote end overlapping?

    If this is the scenario

    192.168.5.0 ASA1 <---> <-- internet="" --="">ASA2<-->

    ASA1 (NAT will be applied)

    ASA2 (without nat will be applied)

    You want to do something like that on ASA1

    Change your source host or network to be 192.168.7.0 when communicating with the remote network. Change the remote network to come as long as 192.168.8.0 coming to your network on the SAA.

    Complete the VPN configuration using acl_match_VPN as the ACL match. Your inside host will have to use the 192.168.7.0 network when you talk to the remote end.

  • vpn NATting traffic

    I have my vpn set up exactly as I need.  Users can connect to the vpn and get an IP of 172.16.17.0/24.  These users can access then machines hidden behind the asa on the private interface 172.16.16.1/24.  Users on the 172.16.16.1 interface can also access any machine not on the private through the router using nat interface.  What I can not understand how is allowing vpn also users to access any machine not on the private via NAT on the router interface. Help would be appreciated.

    If your VPN users connect on the side of the SAA Public then I still think Hairpining is what you should look into. It is very similar to my problem in which I want to VPN users to access internet through VPN. Packets from the VPN users must enter the public interface and return directly. I hope I understand this.

  • ASA 8.3 - SSL VPN - NAT problem

    Need help to find how to configure anyconnect VPN with VPN client using a NAT networking internal.

    There are many items on the side - how to disable NAT for vpn pool.

    I need to create the gateway VPN to the complex international lnetwork, vpnpool is out of range of regular subnet of that network, so it's going to be questions witout NAT routing.

    I so need to vpn clients connected to be PATed to . The problem is that there is also a dynamic to PAT rule for the ordinary acccess Iternet which translates as 'rules NAT asymmetry... "error.

    Create two times different NAT rules and moving them on up/down makes no difference. There are also some hidden rules of vpn setup :-(that could not be seen.

    V8.3 seems is destroying trust in Cisco firewall...

    Thank you.

  • After VPN NAT

    Hello

    I have the following problem and can't seem to find a solution.

    I have 2 routers Cisco, A and B with a VPN connection. Two routers have a serial number

    interface pointing outside and an ethernet interface (allows to call the A and B)

    pointing to the inside.

    Traffic between Subnet A and B is NOT coordinated and VPN works great.

    Now router B has a second ethernet (C), subnet C interface.

    I added this subnet to the IPSEC ACLS on both routers as I want to allow A subnet

    access subnet C via the VPN.

    The tunnel is running with no NAT is done.

    However, the B, B and C subnet access router is using a NAT:

    Interface B

    IP nat inside

    !

    The C interface

    NAT outside IP

    !

    IP nat inside source overload map route NAT interface C

    !

    route NAT allowed 10 map

    corresponds to the IP 123

    !

    access-list 123 allow ip SUBNET_B SUBNET_C

    So far so good. Now the problem:

    How can I NAT traffic from subnet to subnet A C?

    I tried to add

    access-list 123 allow ip SUBNET_A SUBNET_C

    but it does not help that the outbound VPN seems to not be affected by the

    NAT rule, probably because it is not considered as coming from an interface with ip nat «»

    inside. "

    Is there a way to do this without using the tunnel interfaces?

    Thanks in advance,

    If I understand you correctly, you want traffic from subnet A reach router B, deciphering, NATted interface B and thten routed to interface C.

    Please correct me if I'm wrong.

    You can use ACB (routing based on the policy) for this.

    Create an ACL to identify traffic:

    access-list 101 permit ip subnet A subnet C

    Create a loop:

    Loopback int 1

    IP 1.1.1.1 255.255.255.252

    IP nat inside

    output

    Create a road map to route traffic after its decrypted.

    pol_nat allowed 10 route map

    corresponds to the IP 101

    set ip next-hop 1.1.1.2

    output

    Apply the road map to your WAN interface:

    int 0 series

    IP policy route map pol_nat

    output

    In this way, traffic is first decrypted and is routed to the loopback, which has a 'ip nat inside' applied, then it will be routed to the subnet C after being natted with your NAT rule.

    * Please rate if this can help.

  • PIX 515E v7 VPN config help

    Hello

    I have a PIX 515E current of execution to 7.

    Is it possible to use VPN with only 1 static IP address from the ISP (no gateway or the ip address of the ISP router is provided).

    I can set up routing on the ADSL modem, but then the PIX does not have a valid Internet IP address?

    I think that v7 does not support PPPOE? so I can't set the mode on the bridged adsl modem?

    Is there a way to fix this?

    Any help appreciated gratefully.

    apply the commands below:

    ISAKMP identity address

    ISAKMP nat-traversal 20

    If the problem persists, then please post the entire config with ip hidden public.

  • Site to Site VPN NAT conflicts

    I have a site to site vpn between my main office and an office.  Traffic between flow correctly with the exception of some protocols.  My main router has static NAT configured for port 25 and a few others.  For each of these protocols that have a static nat, I can't send the traffic from my office to the IP in the static nat

    either I can't access port 25 on 172.16.1.1 of my office of the branch of the 172.17.1.1, but I have remote desktop access

    It's like my list of NAT is excluding the static entries that follow.  I have posted below the configs.  Any help would be appreciated.

  • VPN / Natting issue - connectivity to 3rd Party Partner Site

    Hello

    I received a request to provide a connectivity solution between our private server 10.102.x.y and a3rd advantage partner server. 10.247.x.y solution of VPN site to site. I want to hide our real IP of 10.102.x.y and replace 10.160.x.y (using Natting).

    The configuration is the following:

    Any help on this would be appreciated.

    Thanks in advance,

    Select this option.

    Hello

    Who will break actually internet traffic with this server because the external address that is sent over the internet is considered to be a 10.160.x.y.  In the past, I did something like this:

    public static 10.160.x.y (Interior, exterior), list-dest-3rdParty access policy

    policy-dest-3rdParty of the ip host 10.102.x.y host 10.247.x.y allowed extended access list

    Who will ONLY perform NAT traffic on this server if traffic is coming from the 10.247.x.y.

  • ASA VPN (NAT problem)?

    Hi people, I was hoping sopmeone on these forums might be able to help. I have some problem with a config for our ASA5510, functioning 8.2 (1)

    I installed a VPN tunnel a firewall to vyatta off-site. The tunnel is up.

    ABN-FW3-CISCO ASA5510 # show crypto ipsec his

    Path mtu 1500, fresh ipsec generals 58, media, mtu 1500
    current outbound SPI: 670F3BF5

    Now I can pass information of the 119.252.X.X to our internal networks (192.9.0.0/16) vyatta (yes I know this is a wide audience, but it comes to the environment, I inherited, I'm running with a project to put private network addresses, but its not finished quite yet)

    The problem seems to be information of ASA to the internal network behind the vyatta - 192.168.11.0/24.

    When I check my syslog I get the following error: (this example has been a connection attempt mstsc)
    : Inbound TCP connection deny from 192.9.216.190/60660 to 192.168.11.101/3389 SYN flags on the interface inside

    Now Im guessing this SYN message means that the ASA trying to NAT my outgoing packets... which is strange because I have configured a rule sheep. But when I do a show nat is the result:

    ABN-FW3-CISCO ASA5510 # display nat inside
    is the intellectual property inside 192.9.0.0 outside 192.168.11.0 255.255.0.0 255.255.255.0
    Exempt from NAT
    translate_hits = 0, untranslate_hits = 37 (this value does not change)

    Here is my config for NAT

    Inside_nat0_outbound to access extended list ip 192.9.0.0 255.255.0.0 allow 192.168.11.0 255.255.255.0

    (I have a separate ACL for interesting traffic)

    static (inside, dmz) 192.9.0.0 192.9.0.0 255.255.0.0 subnet mask

    Im guessing that one of these rules is in conflict? Does nat (inside) 0 Inside_nat0_outbound access list take precedence over the nat (inside) 1 0.0.0.0 0.0.0.0?

    I can post more if necessary config, any help at this point would be much appreciated

    Hmm looks like you establish 192.168.11.0 who seems to be blocked by the ACL on the traffic of 192.9.0.0 inside the interface.

    Please paste config ACL or see if that blocks this traffic.

    Thank you

  • VPN - NAT Exemption?

    Hi all

    Just a mental block, I feel at the moment.

    ASA 5585 code 9.0.x race - there is no NAT configuration at all on the box. This ASA firewall will end a site to site VPN. -

    My question is - is a rule of "NAT exemption" required... .similar to the crypto ACL for the traffic in the tunnel... .or is NAT exemption required only when NAT is configured.

    My apologies if this is a silly question

    Thank you

    James

    When there is no NAT config, the ASA will pass all traffic not translated, which includes the traffic tunnel. If you're right, you don't need any NAT exemption.

    However, you can configure it. For example, if you plan to add NAT at a later stage, then it might be easier to implement than NAT if your NAT exemption is already in place.

  • Configuration VPN - NAT - T support

    Hello

    A partner of business (BP) has the following requirements. I don't know which statements of config I need to use to ensure this successful connection

    Business (BP) needs partner complete the VPN tunnel on a firewall that is behind another firewall running NAT

    (BP) will create UDP 500 and UDP 4500 endpoints on the NAT firewall which is forwarded to the Firewall VPN termination.

    Because of this, the (BP) needs of my dissertation support encapsulation of ESP over UDP (NAT - T)

    My series of ASA5500 using the code (825) has the statements

    Crypto isakmp nat-traversal 21
    crypto ISAKMP ipsec-over-tcp port 10000

    VPN # match address BP_VPN crypto card
    VPN # set peer (peer_ip) crypto card
    VPN # game of transformation-AES_256_SHA crypto card

    IPSec-l2l type tunnel-group (peer_ip)
    IPSec-attributes of tunnel-group (peer_ip)
    pre-shared key (TBD)

    BP_VPN list extended access permit tcp host 10.x.x.x, 172.16.x.x eq (specified port) host
    BP_VPN list extended access permit tcp host 10.x.x.y host 172.16.x.x eq (specified port)

    NatExempt_VPN list extended access permit tcp host 10.x.x.x, 172.16.x.x eq (specified port) host
    NatExempt_VPN list extended access permit tcp host 10.x.x.y host 172.16.x.x eq (specified port)

    Please indicate whether these statements are sufficient and if not what else would be needed.

    You need not order

    crypto isakmp ipsec-over-tcp port 10000
    It is for the exclusive implementation that was used before NAT - T is available. You only need to nat-traversal active. For your ACL, using ports in there makes everything complicated. You should see if you can just use 'ip' here. If there is already configured on your ASA virtual private networks, then the config is probably ok. If this isn't the case, you must always configure ISAKMP and activate the encryption on the interface card.
