ASA IPSEC VPN BEHIND A ROUTER WITH AN INVALID IP ADDRESS

HY guys,.

I have a question.

I need to build a VPN IPSec using the ASA 5500 firewall, but I only have an invalid ip address on my 192.168.x.y external interface. This interface is connected to the Ethernet router, the supplier making a single default address route valid 200.140.x.y through the interface outside of the

ASA-5500.

How can I publish this valid address of 200.140.xy for access to my VPN users?

The topology is attached.

Please help me... /.

Thank you very much

Anderson

Hello

First of all, it's not Miss... It is Mr.

For your question, the configuration, your ISP is to translate the

public IP address of your ASA within intellectual property. So, I don't see any problems there.

I noticed one thing is your default gateway of firewall vers.1

When inside the interface of router ISP est.4. To check connectivity, try

What follows:

on the firewall:

SSH 0.0.0.0 0.0.0.0 outdoors

generate crypto module rsa keys 1024

Once the above commands are entered, try to ssh to the public IP address. If you

are able to connect to the ASA using the public IP address, which means that the public IP address

is directly translates to the ASA and you shouldn't have a problem

using this IP address to the VPN.

I hope this helps.

Kind regards

    Hello

    is it possible to access the RDC to two XP systems, with two different port for the DRC, behind a router with a single public IP address?

    Please note this ia a small home network without any parameters of the field. I use IP to access DRC.

    You comments are appreciated.

    Thank you

    Use different ports for the DRC on both XP and configure the router to redirect to the appropriate port on the appropriate computer.

  • ASA IPSEC VPN with public IP dynamic

    Hey,.

    I have never deployed IPSEC VPN tunnel using ASA on two sides of a side using public IP dynamic production. I normally deploy VPN Tunnels with both sides using public static IP addresses (not always a public IP address on ASA directly however).

    So I wonder how stable it works with a static public IP and the other side uses dynamic public IP?

    Thank you

    Shuai

    If you use certificates and psk or main mode and aggressive it will work very well. I have a number of production sites using this method.

  • Cisco ASA 5510 VPN Site to Site with Sonicwall

    I am trying to configure a tunnel between a Cisco ASA 5510 VPN (Version 8.2 (2)) and TZ200 Sonicwall. I rose tunnel and go and I am able to ping the internal IP address of Cisco ASA of the Sonicwall LAN but nothing work. When I try to ping a host behind the Cisco ASA of the Sonicwall LAN I get the following message "rules asymmetrical NAT matched for flows forward and backward; Connection for tcp src outside:10.20.10.x/xxxx dst inside:10.20.2.x/xxxx refused due to failure of reverse path of NAT"on the SAA

    Googling the error above shows the problems with version 8.3 or later that resembled the nat commands have been changed SAA, train is still on 8.2 but I another common question does not add an exemption of NAT I have double-triple checked that I did add an exception rule of NAT of the hosts on the network from cisco for the guests of the Sonicwall network. Looks like I hit a road block so any help would be appreciated. Thank you

    Hello Manjitriat,

    Okay, detected IPSEC parody is normal, that means you are trying to send unencrypted on a line of encrypted packets.

    Now, if you see on the plotter of package that traffic will hollow the VPN channel all its fine in your site.

    Now the packet tracer must be something like this:

    entrance to Packet-trace inside private_ip_lan destination_private_ip_lan 1025 tcp 80

    Please provide us with the result of the following instructions after you run the packet tracer.

  • Customer Cisco IPSec vpn cisco ios router <>==

    Hello

    I need to implement ipsec vpn for all users of 10-15. They all use the vpn cisco 5.x client and we have a router for cisco ios at the office. We already have a situation of work for these users. However, it has become a necessity which known only devices (laptops company) are allowed to install a virtual private network.

    I think that the only way to achieve this is to use certificates. But we don't won't to buy certificates if there is a free way to implement. So my question is

    (1) what are the options I have to configure vpn ipsec, where only known devices can properly configure a vpn and all unknown devices are blocked?

    (2) if the certificate is the only way. Can I somehow produce these certificates myself using cisco router ios?

    (3) someone at - it an example of a similar installation/configuration?

    Thanks in advance.

    Kind regards

    M.

    Unfortunately if you connect to the router IOS, there is no other way except using the certificate. If you connect to a Cisco ASA firewall, then you can identify the laptop company using DAP (Dynamic Access Policy).

  • The IOS IPSec VPN configuration Cisco router

    Hi experts,

    I have not configured the VPN for a long time on the routers so I want your recommendation on best practices.

    I need to run OSPF over it, so it must be GRE over IPSec

    I googled and I see the old type of config that I used to do with the use of the crypto map. Then I see config with profile Ipsec that is applied to the interface of tunnel (tunnel protection). I also see on the manual on isakmp profile...

    Is there an example of configuration that you can provide? This is site to site VPN with PAT most basic on the interface for the remote desktop for surfing the Internet. My routers are fairly recent. One is 2821 with new 12.4 T code and another 2921 router.

    Thank you

  • ASA 5505 VPN Site to site with several networks

    Hello

    I have a Cisco ASA 5505 configuration problem and hope you can help me.

    Our company created a second facility, which must be connected using VPN to our headquarters.

    I used the ASDM "Wizard of Site to site VPN" to create a connection, which works very well with our main network.

    Following structure:

    Headquarters:

    Cisco ASA 5505, firmware 9.1, ASDM version 7.1

    Outside: Fixed IP

    Inside: IP address of the interface is 192.168.0.1/24 (data network)

    Now I have a second network 192.168.1.0/24 (VoIP network), PBX address is 192.168.1.10.

    The two networks should be accessible through the VPN.

    New installation:

    Cisco ASA 5505, firmware 9.1, ASDM version 7.1

    Outside: Fixed IP

    Inside: IP address of the interface is 192.168.2.1/24

    I have already created a connection until a PC of the new plant reaches the data network. For example, a ping from 192.168.2.100 to 192.168.0.100 is possible.

    Now, I want to add some VoIP phones to the new facility, which can reach the PBX on 192.168.1.10.

    In the link, I have already added the two networks as remote network:

    object-group network Testgroup network-object 192.168.0.0 255.255.255.0 network-object 192.168.1.0 255.255.255.0 access-list outside_cryptomap extended permit ip object-group Testgroup object Remote-Network

    My problem now is, I don't know what to define as 'Bridge' on my PBX.

    I can't use 192.168.0.1 because it's a different subnet. Also, I can not put a second IP 192.168.1.1 to the interface of the ASA.

    You have any ideas, how can I accomplish this, so that the two subnets are accessed through the VPN and all devices have a defined gateway?

    Could a "Easy VPN Remote" in "Network Mode" you help me?

    What is the difference between 'Site-to-site' and 'extended network '?

    Kind regards

    Daniel condition, look for the solution GmbH

    You can optionally configure a new LAN VIRTUAL (VLAN PBX) on the SAA and connect this interface to the voice network.

    If you do not have a spare on the ASA port, then Yes, you have a router to route traffic from the PBX to the ASA via the data network.

    Yes, you will need to either configure split tunnel so that internet traffic goes out through your local Internet service provider, GOLD / directed by configuration current you are tunneling all traffic (internet traffic Inc.) to the ASA, then you will need to create NAT for internet traffic.

    To set up a tunnel from split:

  • VPN site to Site on firewall with no public IP address

    Dear all,

    I have a VPN from Site to Site configuration requirement with accommodation, I have my internet connection on the router termintaed and got only a single public ip address. My ASA is behind this router with no public IP (attached chart). This router will not support VPN and I need to configure VPN on the firewall.

    192.168.20.0/24 is the network between the router and firewall. 192.168.10.0/24 is inside the network. (attached diagram have the most details)

    Please advice the configuration to achieve this...

    Thanks in advance...

    Mikael

    If the router cisco so the configuration would be:

    IP nat inside source static udp 192.168.20.2 500 500 extensible interface

    IP nat inside source static udp 192.168.20.2 interface 4500 4500 extensible

  • SA520 and Question IPSec VPN RVS4000

    Hello

    I installed an IPSec VPN for one of my friends for his company. At its principal office, I installed a Cisco SA520 and he uses to connect devices such as the iPhone and iPad via the IPSec VPN. He uses this fact because he travels abroad a lot and he has problems with services such as Skype is blocked in some countries. This configuration works very well.

    It also has a Cisco RVS4000, which he would like to install at his place of business to the Mexico. He would like the RVS4000 VPN configuration to the SA520 in his office. The SA520 in his office has a static IP address. The RVS4000 to the Mexico does not work.

    Is it possible to Setup IPSec VPN between a SA520 with a static IP and RVS4000 address that does not have a static IP address? If so, examples of configuration would be greatly appreciated.

    Thank you!

    Hi William, simply sign up for a dyndns account or similar service, the RVS4000 configuration will be the same, instead of the IP, you'd be using the dyndns name.

  • 2 IPSec VPN + DMVPN

    Hello.

    Could you please tell me, how to create the second IPSec VPN on my router if crypto card is already set to the interface, and there is no other. This interface is also the NHRP\DMVPN interface. Router is a hub.

    Hey, Nikolay.

    For new dmvpn cloud you don't don't have set up a crmap to the interface. You can create a new tunnel interface and link a different transfer for her.

    If you want to add an IPsec-l2l connection or a new EasyVPN you can look at this example:

    Crypto ipsec transform-set esp-3des esp-md5-hmac trset1
    transport mode
    output

    Crypto ipsec transform-set trset2 aes - esp esp-sha-hmac

    map CRNAME 1 ipsec-isakmp crypto
    Description - VPN - 1
    defined peer IP_1
    Set transform-set trset1
    match address ACL_1
    output

    map CRNAME 2 ipsec-isakmp crypto
    Description - VPN - 2
    defined peer IP_1
    Set transform-set trset2
    match address ACL_2
    output

    interface FastEthernet0/0
    Description - outdoors-
    card crypto CRNAME
    output

    For an EasyVPN (or any other dynamic encryption card), you can use this example:

    crypto dynamic-map DYNMAP 1
    transform-set Set feat
    market arriere-route
    output

    card crypto crmap 3 - isakmp dynamic ipsec DYNMAP

    And example for DmVPN clouds to the 1 Router 2:

    Crypto ipsec transform-set esp-3des esp-sha-hmac trset_1
    tunnel mode
    output
    Crypto ipsec transform-set esp-3des esp-md5-hmac trset_2
    transport mode
    output

    Crypto ipsec Dmvpn-Profile1 profile
    Set transform-set trset_1
    output
    Crypto ipsec profile Profil2 dmvpn
    Set transform-set trset_2
    output

    Tunnel1 interface
    [network] IP address
    dynamic multicast of IP PNDH map
    PNDH network IP-1 id
    source of tunnel FastEthernet0/0
    multipoint gre tunnel mode
    key 1 tunnel
    Tunnel protection ipsec Dmvpn-Profile1 profile
    output

    interface tunnels2
    [network] IP address
    dynamic multicast of IP PNDH map
    PNDH network IP-2 id
    source of tunnel FastEthernet0/0
    multipoint gre tunnel mode
    tunnel key 2
    Profile of tunnel dmvpn Profil2 ipsec protection
    output

    Best regards.

  • VPN site-to-site with pppoe ADSL connection

    Dear

    I would like to know - is it possible to connect two 5505 ASA in VPN site-to-site with 1 site using the pppoe ADSL connection?

    A (static IP) site

    Site B (ADSL pppoe, DHCP)

    Site has < site="" to="" site="" vpn=""> > Site B

    Best regards

    Alan.

    Configuration of site B should be the same as all the other side than peers with static end.

    The different configuration would be on Site A as he will accept a VPN to a dynamic counterpart.

    Unfortunately, I have no configuration example to show you on ASDM.
