• 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.

• NAT and vpn acl

  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 172.18.0.0

  This '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

• 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.

• 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.

  Hello

  I had first change in the pool of VPN Client to something other than the LAN

  As 192.168.1.0/24

  NAT0

  • Adding NAT0 rule for the new pool and then removing the 'old'

  permit access ip 192.168.0.0 scope list inside_nat0_outbound 255.255.255.0 192.168.1.0 255.255.255.0

  no access list inside_nat0_outbound extended permits all ip 192.168.0.192 255.255.255.192

  No inside_nat0_outbound extended access list only to allowed ip 192.168.0.0 255.255.255.0 192.168.0.96 255.255.255.240

  VPN Client pool

  • Remove the old group "tunnel-group" configurations, then removing the pool, make a new pool, and finally configure the pool to group "tunnel".

  tunnel-group vpn_client General-attributes

  No address vpn_pool pool

  no ip local pool vpn_pool 192.168.0.100 - 192.168.0.105 mask 255.255.255.0

  Theres another thread with a similar problem (even if the settings appear to be correct) on the forums.

  If you can't get the RDP connection works I would also maybe Google for UltraVNC and its installation on the host LAN and your VPN Client and trying to connect with him to determine that the Client VPN configurations are all ok. There were problems that were ultimately associated with the LAN host rather than the VPN Client configurations.

  If you think that his need. Save your settings before making any changes.

• How to configure NAT for Hyper-V on laptop with wifi, wired and vpn connectivity

  Me, as I suspect a lot of people, I have a laptop with WiFi connection, cable connection and VPN connection (Cisco AnyConnect), which

  also uses a virtual adapter (activated when active). I searched for some time a way to be able to move to

  Hyper-V in VirtualBox. Blocker full for me is the need for a lot of my virtual machines to be able to connect to the

  Internet through 'the connection active' in the way that VirtualBox and VMWare Workstation/Player through their NAT feature.

  I'm not a networking wait, but after looking around, can't seem to find something that is simple enough for me to configure,

  with a minimum of resources, which allows me to connect a Hyper-V virtual network via a simple NAT device adapter

  all three potential network connections - most seem to not assume that one connection out of the machine, which of course does not

  me what I want.

  Three questions:

  1. is there a Windows application available that an adapter (like loopback) internal which acts as a real NAT device to one of the surfaces

  external access via the active network connections and through the Windows Firewall and any other antivirus, components etc. for

  the road to (i.e. behaves like a "normal app" inside Windows for internet access)? It would be the best option, because it would be

  "always there" when I run virtual machines

  2. display of my lack of knowledge around this feature, don't RRAS (and I know that this is not an option "minimum contact") allow you to

  Connect an internal network adapter to several external network adapters?

  3. on the Linux/OpenBSD various base/NAT routers, are everything that allow several external adapters and who are

  relatively easy to set up (by an independent expert of the network)?

  Really, we could do with this feature for Hyper-V on the desktop, but willing to work around him, if there is a way to at least the

  use virtual machines, once it is easy to install.

  Hello

  The question is more suited in the TechNet forums. So I would say you mention the link and send the request in this forum for better support.

• ASA 5510 - VPN for DMZ with static rule?

  I have a 5510 ASA with a number of virtual private networks to other sites, allowing the traffic to and from the Interior of the networks.

  I need to establish a VPN rule to another site, but they have very little access to resources on my local network.  Because I am not in control of the SAA on this end permanently, I need to control that access on my 5510.

  (the following is not my real IP, but I use them for this example)

  My network: 10.100.1.x

  My DMZ: 192.168.1.x

  Internal network of other sites: 172.16.1.x

  I wanted to try to create a VPN between the site and the specific address of DMZ on my side and then allow access to internal addresses using static rules.  I decided to use a static rule to enable http access to a specific server (for example):

  static (inside, dmz) 192.168.1.200 tcp 80 10.100.1.200 80

  I need allow traffic here:

  access-list permits DMZ_IN tcp host 172.16.1.10 host 192.168.1.200 eq 80

  Access-group interface dmz DMZ_IN

  And of course, rules of access list which allow traffic that I can apply to the VPN:

  toSite host 192.168.1.200 ip access list permit 172.16.1.10

  And I don't want that traffic THAT NAT had between my DMZ and the other site:

  nonatDMZ of the host 192.168.1.200 ip access list permit 172.16.1.10

  NAT (dmz) 0-list of access nonatDMZ

  NAT (dmz) 1 0.0.0.0 0.0.0.0

  And, of course, the corresponding rules on their ASA must be in place, allowing traffic to 192.168.1.200, not NAT it.

  Everything is in place, but 172.16.1.10 to 192.168.1.200 http traffic never reaches 10.100.1.200.  I know the following:

  1. the VPN is configured correctly.  If I add rules allowing traffic to (and from) 172.16.1.10 and 10.100.1.200 directly, they work.

  2 packet trace shows me that traffic is allowed.

  3. the works of static rule: to access the 192.168.1.200:80 of another host on the same interface, DMZ, which brings me to 10.100.1.200:80

  4. in the process of running a sniffer package on 10.100.1.200 shows 172.16.1.10 traffic does not reach it.

  So I'm banging my head against the wall here.  I'm sure it's something simple I'm missing.  Anything else I need to check?  Should I go about this a different way?

  Thank you.

  What you are trying to reach is not supported. You cannot configure NATing between the inside and the demilitarized zone interfaces while your VPN connection is from the external interface. The static NAT (inside the dmz) that you have configured will only work if the connection is initiated from the inside towards the demilitarized zone and vice versa.

  I think that what you are trying to reach is only allowing access on TCP/80 to10.100.1.200 for the VPN tunnel.

  You must configure your option 1:

  1. the VPN is configured correctly.  If I add rules allowing traffic to (and from) 172.16.1.10 and 10.100.1.200 directly, they work.

  You can configure vpn-filter to limit the traffic to the only TCP/80, and he attributed to group policy that you have assigned to this particular tunnel group then.

  Example:

  web access list - allow permit tcp host 172.16.1.10 host 10.100.1.200 eq 80

  internal group-policy-strategy web

  attribute group web-strategy strategy

  value of VPN-filter web - allows

  global-tunnel-group attributes

  Group Policy - by default-web-policy

  Here is an example configuration for your reference:

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.

  http://Windows.Microsoft.com/en-us/Windows-Vista/startup-repair-frequently-asked-questions

  Method 2:

  I also suggest you to perform the system restore and check.

  System Restore: Put the computer to an earlier point in time, when everything worked well. If the system restore is a recovery preinstalled on your computer option:

  Restart the computer manually.

  (a) do one of the following:

  a. If your computer has a single operating system installed, press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you need to try again by waiting until the Windows logon prompt appears, and then stop and restart your computer.

  b. If your computer has multiple operating systems, use the arrow keys to select the operating system you want to repair, and then press and hold F8.

  (b) on the screen Advanced Startup Options , use the arrow keys to select repair your computer, and then press ENTER. (If repair your computer is not listed as an option, then your computer does not include restoration of the system as a preinstalled recovery option.)

  (c) select a keyboard layout and then click Next.

  (d) select a username and password, and then click OK.

  (e) on the System Recovery Options menu, click System Restore. Put the computer to an earlier point in time, when everything worked well.

• Wireless and VPN RV042 router WRT54G

  Respected member, please help if you can! I have an ADSL with dynamic connected with the wrt54g router, I recently bought RV042 and want to connect the wire coming from wireless with ports. so, basically, I want to use RV042VPN for help after the router, is there a way I can use vpn behind with port using RV042 router wireless

  I can't be able to connect to the vpn as he seeks is not an ip or WAN/LAN.

  It may be possible if you're lucky. But I highly recommend not to connect the RV042 after the WRT. A VPN server must always have a public IP address. Running a VPN server behind a router NAT (such as WRT) makes it extremely difficult and often it won't work at all. Connect the RV042 directly to your modem, configure it to your internet connection. In this way the RV042 has the public IP and VPN should become much easier. Then implement the WRT as simple access point in your network by changing the address LAN IP of 192.168.1.1 to 192.168.1.2, disable the DHCP server, and connect a LAN port of the WRT on a LAN on the RV042 port.

• Order of procedure SonicWALL for routing, NAT and policies

  I'm confused on the prescription that the sonicwall verifies a package.  The way I heard the order, it will:

  (1) check against the access rules,

  (2) check against NAT Polies

  (3) check the routing.

  Installation program:

  Subnet point of VPN endpoint - Internet - SW NSA 2400 (VPN) - sub-network B (from C subnet)

  A subnet is 10.1.100.x/24

  Subnet B is consists of three IPs, 192.168.99.4,.50, and 109.

  Subnet C is contains the host IPs 192.168.13.4,.50, and 109.

  I VPN configured to allow traffic from 10.1.100.x to the hosts on the subnet B, what NAT and the host subnet C.  This method works more large, is not a problem.

  I need to reduce access to certain ports.  Once I set access restrictions in the port, the firewall blocks ALL.

  When I look at a screenshot of packets when traffic is blocked, I see the following:

  Source 10.1.100.5--> 192.168.99.4 accepted

  Source 10.1.100.5--> 192.168.13.4 refused.

  Block of code indicates that it is because of politics.  However the policy review should have been checked and checked already.  If I change the VPN policy to represent both sides of the NAT (ie. 192.168.99.4 and 192.168.13.4) then passes the traffic.

  If anyone can explain what is happening?

  I tried to look through some KB SonicWall has publicly available articles. But I did not see anything that doesn't seem to help. In this case, I think you might want to give SonicWall support a call.

  https://support.software.Dell.com/manage-service-request

  They can help to look over your configurations and see if we have to make changes. They should also be able to answer your technical questions about how the packets are received or managed.

• IPSec Tunnel between Cisco 2801 and Netscren 50 with NAT and static

  Hello

  My problem isn't really the IPSec connection between two devices (it is already done...) But my problem is that I have a mail server on the site of Cisco, who have a static NAT from inside to outside. Due to the static NAT, I do not see the server in the VPN tunnel. I found a document that almost describes the problem:

  "Configuration of a router IPSEC Tunnel private-to-private network with NAT and static" (Document ID 14144)

  NAT takes place before the encryption verification!

  In this document, the solution is 'routing policy' using the loopback interface. But, how can I handle this with the Netscreen firewall. Someone has an idea?

  Thanks for any help

  Best regards

  Heiko

  Hello

  Try to change your static NAT with static NAT based policy.

  That is to say the static NAT should not be applicable for VPN traffic

  permissible static route map 1

  corresponds to the IP 104

  access-list 104 refuse host ip 10.1.110.10 10.1.0.0 255.255.0.0

  access-list 104 allow the host ip 10.1.110.10 all

  IP nat inside source static 10.1.110.10 81.222.33.90 map of static route

  HTH

  Kind regards

  GE.

• 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?

• Can fast VPN and VPN Cisco coexist (WRVS4400N)

  I am looking to buy a WRVS4400N to take care of my home network.  While I get out on the road I want to VPN in my home network to my laptop (on which I installed Cisco VPN for the company's mobile access to my corporate network).  In this spirit, I have three questions:

  1. is the Cisco VPN client on my laptop be able to establish a VPN connection to unity WRVS4400N?  I suspect not, and instead, I have to use fast VPN.

  2. I understand there are problems in co existence with different suppliers, VPN clients (when I tried before with a Netgear router, the VPN Netgear client broke the Cisco VPN client).  Quick VPN client Linksys can coexist with the Cisco VPN client without any problems?

  3. a last resort, if Cisco and Linksys VPN can coexist, install the client quick VPN Linksys inside a VM Ware image would work (while the Cisco VPN client is still installed in the host operating system).

  Thanks much for any help.

  (1) correct.  For WRVS4400N QVPN

  (2) I run the Cisco VPN CLient and VPN fast on my laptop and seems fine
