NAT over VPN Tunnel

Similar Questions

• SIP over VPN tunnel

  We have VPN tunnel in our firewall with the other partner peer. We use ASA 5520 with IOS "asa825-k8" and ASDM version 6.4.

  our partner has several services running in this tunnel VPN, including the SIP.

  other services work very well only SIP connections cannot come.

  the question is we allowed any IP service on the inside and outside interfaces, but this topic could not come to the top.

  is - there any SIP over VPN option must be configured on ASA?

  Hello

  As you can see in the newspapers, it is denied to the inside interface.

  If you just need to allow this by opening an ACL for this traffic on port 5060.

  I would like to know if it works.

  Kind regards

• 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.

• NAT over VPN IP Pool

  Hello

  I just want to ask if it is possible to NAT pool users to remote access ip VPN to the router is outside the IP address? The router is a Cisco1841.

  Thank you!

  Patricia,

  Are you referring to Polo your RA IP pool using your external interface just like you with your LAN subnets in ip nat overload?, if so this link illustrates similar example using the road map, PLS let know us if this isn't what you're looking for and if you could perhaps develop as that is what you try to accomplish.

• NAT, ASA, 2 neworks and a VPN tunnel

  Hello. I have a following question. I am trying to establish a VPN tunnel to a remote network used to be connected to our via a VPN tunnel. The problem is that the previous tunnel their share has been created for the x.x.x.x our coast network which will serve no more time a month, but is currently still active and used. As I'm trying to get this VPN tunnel as soon as possible without going through all the paperwork on the other side (political, don't ask) is it possible to make NAT of the new network in the network x.x.x.x for traffic through the VPN tunnel.

  Something like this:

  new network-> policy NAT in old x.x.x.x fork on ASA-> VPN tunnel to the remote network using x.x.x.x addresses

  It is possible to add the new policy, but sometimes it can conflict with the former.

• With NAT VPN tunnels

  I have read on several posts on the topic and still think I'm missing something, I'm looking for help.

  Basically, I'm now implementing multiple VPN tunnels for external connections. We strive to keep the external "private addresses" our basic using NAT network.

  I can get the Tunnel to work without problems using the ACL SHEEP; However, this technique requires that our internal network is aware of their external addresses "private." Our goal is to enter an address on the inside that is NAT to the external address 'private' and then shipped via the VPN tunnel. Basically to hide the external address 'private' of our internal systems that they would appear as thought the connection was one of our own networks.

  The reverse is true coming from their external 'private' network. Any information of "their" private network external origin would result in our 'private' on arrival address space.

  Is this possible? I am attaching a schema, which could help.

  Hello

  Yes, this should be possible. Lets say you allocate 10.112.2.250 as the address that you use to present the external server 192.168.10.10.

  On your ASA device

  public static 10.112.2.250 (exterior, Interior) 192.168.10.10 netmask 255.255.255.255

  You will need to make sure that when the system tries to connect to 10.112.2.250 it is routed to the device of the SAA.

• Making the NAT for VPN through L2L tunnel clients

  Hi.I has the following situation in my network. We need for users who log on our site with the VPN clients to connect to another site via a tunnel L2L. The problem is that I need NAT addresses from the pool of VPN client in another beach before going on the L2L tunnel because on the other side, we have duplication of networks.

  I tried to do NAT with little success as follows:

  ACL for pool NAT of VPN:

  Extended list ip 192.168.253.0 access TEST allow 255.255.255.0 192.168.0.0 255.255.255.0

  Extended list ip 192.168.253.0 access TEST allow 255.255.255.0 192.168.5.0 255.255.255.0

  NAT:

  NAT (inside) 15 TEST access-list

  CRYPTO ACL:

  permit same-security-traffic intra-interface

  Am I missing something here? Something like this is possible at all?

  Thanks in advance for any help.

  We use the ASA 5510 with software version 8.0 (3) 6.

  You need nat to the outside, not the inside.

• NAT VPN tunnel and still access Internet traffic

  Hello

  Thank you in advance for any help you can provide.

  I have a server with the IP 192.168.1.9 that needs to access a subnet remote from 192.168.50.0/24, through the Internet.  However, before the server can access the remote subnet, the server IP must be NAT'ed to 10.1.0.1 because the VPN gateway remote (which is not under my control) allows access to other customers who have the same subnet address that we do on our local network.

  We have a 2801 Cisco (running c2801-advsecurityk9 - mz.124 - 15.T9.bin) set up to make the NAT.  It is the only gateway on our network.

  I have configured the Cisco 2801 with the following statements of NAT and the relevant access lists:

  access-list 106 allow host ip 192.168.1.9 192.168.50.0 0.0.0.255

  NAT extended IP access list
  refuse the host ip 192.168.1.9 192.168.50.0 0.0.0.255
  deny ip 192.168.1.0 0.0.0.255 192.168.3.0 0.0.0.255
  ip permit 192.168.1.0 0.0.0.255 any

  route allowed ISP 10 map
  corresponds to the IP NAT

  IP nat EMDVPN 10.1.0.1 pool 10.1.0.1 netmask 255.255.255.0
  IP nat inside source list 106 pool EMDVPN
  IP nat inside source map route ISP interface FastEthernet0/1 overload

  When the server (192.168.1.9) attempts to ping on the subnet of 192.168.50.0/24 devices, the VPN tunnel is established successfully.  However, after that, the server is no longer able to access the Internet because the NAT translation for 192.168.1.9 has changed since the external IP address of the router (FastEthernet0/1) at 10.1.0.1.

  The documentation I've seen on the site of Cisco says that this type of Setup allows only host subnet communication.  Internet access is not possible.  However, maybe I missed something, or one of you experts can help me.  Is it possible to configure the NAT router traffic destined to the VPN tunnel and still access the Internet by using the dynamic NAT on FastEthernet0/1?

  Once again, thank you for any help you can give.

• 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.

  • 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

• Impossible to achieve secondary with VPN tunnel

  Hello

  I configured a Cisco Pix Firewall to my VPN tunnels and which works fine when I connect to the local network where the Pix is connected.

  When I want to communicate with a server on a secondary location over the vpn tunnel I get no response.

  The pix can ping the server, but I can't ping the server via the vpn tunnel rooms

  PIX from IP 10.1.0.254

  Router 10.1.10.254 IP address

  Secondary router IP address 10.2.10.254

  Secondary server IP address 10.2.0.1

  The default gateway on the local network is 10.1.10.254

  This router is a gre tunnel 3 of to 10.2.10.254

  On this router, there is a default route for the pix (for internet).

  Hello...

  Make sure that you send the IP pool configured on the PIX of the secondary router/server. just try to ping the IP address that the VPN client is obtained from the server...

  You must also make sure that you add this subnet secondary access sheep... otherwise list your ip pool will see the natted IP server...

  on sheep access list, allow all traffic from the pool of secondary for the IP pool...

  I hope this helps... all the best...

• Try to send all traffic over VPN

  Hello

  I have a Cisco 871 router on my home cable modem connection. I am trying to set up a VPN, and I want to send all traffic over the VPN from connected clients (no split tunnel).

  I can connect to the VPN and I can ping/access resources on my home LAN when I'm remote but access to the internet channels.

  If its possible I would have 2 Configuration of profiles according to connection 1 connection sends all traffic to the vpn and the connection on the other split tunneling but for now, I'd be happy with everything just all traffic go via the VPN.

  Here is my config.

  10.10.10.xxx is my home network inside LAN

  10.10.20.xxx is the IP range assigned when connecting to the VPN

  FastEthernet4 is my WAN interface.

• 3500 x vpn tunnel

  I need to establish a vpn connection between my office and a computer over the internet, allowing access to the internal of the outside lan. I have a problem with my router and I am looking for a new.

  Can I use x 3500 to establish a pptp vpn tunnel or it can work only as vpn passthrough?

  This modem/router supports VPN passthrough for IPSec, PPTP and L2TP only. Try VPN Linksys Gigabit routers like the series of the LRT.

• VPN connected, stream out of VPN tunnel

  I mean that we have in place of the VPN Sites manage to sites with 2 RV042 router but it seams not as I wanted. Are you sure that each transfer of data through Router 2 will go into the VPN tunnel or it shuts down the VPN tunnel. I checked the routing table and saw that:

  Sources mask Gateway Interface

  2 1 or wan wan IP 255.255.255.0 ipsec0 private

  By default 0.0.0.0 (ip wan 1 or 2) wan1 or wan2

  .........

  So what you think what sense data will pass through the line, it will go through the ipsec section or through wan1 or wan2. Ofcouse each data will pass through wan1 or wan2, but it can go inside the ipsec tunnel or ipsec outside tunnel. If she goes inside the ipsec tunnel, everything is ok, but if this isn't the case, transfer of unsecured data. I'm trying to access some website is not in private ip and it was outside ipsec tunnel go, I can capture and now that you have access.

  Why with linksys have 2 work as draytek product even photos follow:

  

  

  Can someone help me to answer this question, thank you for your attention

  1. it depends on what the tunnels of your business allows. As I've written before, there are other protocols that allows you to route traffic through the VPN tunnel. Only IPSec cannot do this. For example, if your company uses GRE over IPSec then they can route traffic through their tunnels. Your RV does not support this.

  2. If it's really plain IPSec then you cannot configure several subnets. You can try to implement the security group remote as a subnet more grand, such as 10.0.0.0/8. Of course the groups must match on both sides.

  3. If you want to route all traffic through the tunnel, and then try to set the local/remote security to 0.0.0.0/0.0.0.0 group. Maybe it works.

  The configuration of IPSec in the RV042 does not allow extremely complex configurations. It's mainly to connect two subnets between them.

• ASA Syslog via a VPN Tunnel

  Hi all

  I have a little problem concerning ASA and syslogs. I have a tunnel from site to site between a local ASA and ASA distance. Behind the ASA local, I have a central syslog server (which has no ASA as default gateway) which collects messages from all network devices and I want to get messages from the ASA remote as well.

  The tunnel protects traffic between local networks behind each ASA, which includes ASA inside remote interface as well. The problem is that if I specify on the SAA distance my syslog server it does not pass through the VPN tunnel. The ASA remote sees my server syslog as being 'outside' so he's using the external IP address as the source-interface for the syslog message. Which of course does not pass through the tunnel. As much as I know there is no way to configure the interface source for logging under the SAA, that you can do on a normal IOS router.

  I've found a few documents explaining this Setup on CCO, but they all imply I have extend the list for interesting traffic to access allow remote UDP/514 of the PIX traffic outside my local syslog server interface. This isn't something I want to do what I would get in routing complication in my LAN with a public IP address of the ASA remote.

  Any suggestions? I thought I could use some sort of NAT on the ASA remote so that all traffic for my local network a source the remote PIX is translated on the inside interface, which in theory should pass the package via the tunnel. I did not go so far.

  Any help is appreciated.

  Best regards

  Stefan

  You can define the interface that the ASA will use to send the newspapers "syslog_ip host record.

  Make sure you also do "access management".

  Then the SAA should source the syslogs from inside the interface, which is probably encrypted with the crypto ACL.

  I hope it helps.
