How to apply internet traffic in VPN tunnel users

Hello

Perhaps it is a simple matter to most of you, but it confuses me right now.

Here's my situation:

home - internet - ASA 5510 users - CORP LAN

We have remote Ipsec VPN and anyconnect VPN, I think that the solution must work on two of them.

My question is: "how to apply internet traffic user home to the VPN tunnel?

We have "split tunnel" to only"'interesting traffic' VPN tunnel access LAN CORP.

but now I need apply all traffic (internet + CORP LAN) user through VPN tunnel passes.

so far, I did what I know:

1. remove the "split tunnle" group policy

2. the address in "remote user VPN address pool" are perhaps NAT/PAT travers ASA5510

but I don't get why it doesn't work.

all suggestions are appreciate!

Thank you!

A few things to configure:

(1) Split tunnel policy to be passed under split in tunnelall tunnel

(2) configure NAT on the external interface to PAT to the same global address.

(3) configure "allowed same-security-traffic intra-interface" so that the tunnel VPN for Internet traffic can make a u-turn.

Please share the current configuration if the foregoing still does not solve the problem. Thank you.

  • Internet via the VPN tunnel

    Hi I have a question.

    I hope one of you can help me.

    My problem is that I want to the internet using VPN tunnenl.

    the client that is connected via VPN you are able to ping 4.2.2.2?

    If Yes, if you issue a nslookup google.com is the resolved name?

  • How to get specific IP through VPN tunnel

    I've implemented remote access via VPN Cisco VPN.
    We use the tunneling split at the tunel internal IP of VPN tunnel only range.
    Now I need to get a specific IP address on the Cisco VPN Client
    through Internet and internal network.
    I added this specific IP address to split tunnel ACL
    I can check it out using Cisco VPN Client, status > statistics, details of the itinerary.
    but when I traceroute to that specific IP address it ends on
    first jump, ASA public interface.
    ASA road 0.0.0.0/0.
    I need to put in place?

    Hello

    If you need to allow the VPN client to connect to the ASA and you--turn to the Internet, you must:

    permit same-security-traffic intra-interface

    Also, make sure you NAT traffic:

    NAT (outside) 1 VPN-range

    Global 1 interface (outside)

    Be careful with the above NAT commands (is just one example and depends on your configuration).

  • How to block all traffic except vpn traffic and traffic bureau HQ

    Hello

    Someone please advise me how to block all traffic except inbound traffic through the VPN and traffic from the IP of the HQ Office.

    My router is 881/K9 Cisco router. Currently, I have blocked all IP addresses with the exception of the IP Office HQ using access-list on the brance office website.

    I put the IP list allowed according to IP location of the VPN user. But now the VPN user become more and more and thus be difficult to block the IPs based on their current location. Sometimes not possible to know their WAN ip address.

    Thanks in advance.

    Have you considered allowing the IPSEC IP Protocol, TCP port, intellectual property all UDP ports and then by blocking all other traffic?

  • AnyConnect: How to route ALL traffic over VPN

    In the past, when I use a built-in Windows VPN (PPTP), I could choose everything would go through the VPN, or if only the things that did not resolve been there. I copy/paste the VPN connection and rename them so we called something_all and the other something_std. I choose which one I needed and start this one.

    Now I use Secure Mobility Cisco AnyConnect Client (on my Windows 7 machine), I don't seem to have this option. I seem to be locked in a mode where only the URLS that fail to solve find themselves through the VPN. It works for the private areas, my employer. This means having access to machines which are not turned to the audience.

    My problem is that, sometimes, I want everything to go through it. For example, if I'm in Europe and that someone (in America) tells me that I need to visit a site and solve a problem, what I find is that despite type in American URL, I get redirected to the European site, because it is a public site. I want to switch the VPN in the mode 'road everything', or even better, to have a list that I manage areas I want to go through it (even if the all or nothing is all that I really need).

    Is this possible? I saw the option called something like 'allow access to the local network', but this doesn't seem to be something useful.

    The ultimate test is that if I go to one of these sites, what - is - my - ip - address, it does not say I'm in Europe, but on the contrary says: I'm in America (or as much as the goal of the VPN is, I have several choices of my employer).

    If instead of "tunnelspecified", we use the keyword "tunnelall" the value with 'split-tunnel-policy', which will push the route 0.0.0.0/0 for the session of your client.

    It is indeed the wildcard character that you are asking about.

  • RV180 VPN route all internet traffic via IPSec VPN

    Hello

    I install my RV180 to VPN to our headquarters Fortigate 60 C. It works really well

    My only problem is that I don't know how to move internet traffic on our remote site by Headquarters. We want to use this technique so that all sites have the same web content filtering provided by our main Fortigate unit. I see clearly that all traffic destined to our internal network will go trough the VPN tunnel, but internet traffic will go through our modem at the remote site.

    My way of fortigate thinking said that I need a static route to transfer all traffic through the VPN tunnel. I've read elsewhere that I need to set up some sort of ACL.

    Anyone else has any ideas on this / has anyone successfully implemented somehting similar?

    Hi Jared,

    I don't think that RV180 takes complete care of tunneling. Complete tunneling allows you to all your traffic to VPN. RV180 made only split tunneling.

    Thank you

  • Send all traffic through the vpn tunnel

    Does anyone know how to send all traffic through the tunnel vpn on both sides?  I have a server EZVpn on one side and one EZVpn client on the other.  I'm not natting on each side.  I use the value default 'tunnelall' for the attributes of group policy.  On the client side all traffic, even if not intended for the subnet of the side server, seems to pass through the tunnel.  But if I ping the side server, the same rules don't seem to apply.  Traffic destined for rates aside customer through the tunnel, but the traffic that is not pumped on the external interface in the clear.  That's not cool.

    Hello

    Clinet traffic to server through tunnel, that's right, right?

    Traffic from server to client through tunnel, but the rest of the traffic is not, no?

    This works as expected because in ezvpn, politics of "tunnel all ' is for traffic is coming from the client., do not leave the server.

    Side server, customer traffic will pass through tunnel, the rest used.

  • Help with a VPN tunnel between ASA 5510 and Juniper SSG20

    Hello

    We have a customer wanting to configure a VPN Site to Site tunnel between a new purchased 5510 of ASA located in his direction with its Juniper SSG20 Office, located in the main office. We contacted HP and they send us a Cisco professional to do the job.

    After 2 days from 16:00 to 22:00 and error and countless hours of research online and nunerous calls, we are still unable to get traffic from the network of agencies to enter the tunnel.

    Main branch
    1.1.1.2                                 1.1.1.1
    -----                                               -----------
    192.168.8.0/24 | ASA|-----------------------------------| Juniper |    192.168.1.0/24
    -----                                               -----------
    192.168.8.254 192.168.1.254

    According to Cisco professionals, the tunnel is now in place but no traffic through. We are unable to ping anything on the network on the other side (192.168.1.0/24). We receive timeout ping all the time. The Cisco professional told us it's a routing or NAT problem and he's working on a solution!

    Through research, I came across a post on Experts-Exchange (here) [the 1st comment on the original post] which States "...". that both sides of the VPN must have a different class of LAN for the VPN to work... " Would that be our problem?

    It has become a critical issue to the point that he had to replace the Cisco ASA with a temporary Juniper SSG5 on another subnet (192.168.7.0/24) to get the tunnel upward and through traffic until the ASA VPN issue is resolved and I didn't need to say that the client is killing us!

    Help is very appreciated.

    Thank you

    1. Yes, ping package from the interface of the ASA is considered valuable traffic to the LAN of Juniper.

    SAA, need you traffic from the interface source ASA's private, because interesting to determine by crypto ACL MYLIST traffic between 192.168.8.0/24 and 192.168.1.0/24.

    You will also need to add the following configuration to be able to get the ping of the interface of the ASA:

    management-private access

    To initiate the ping of the private interface ASA:

    ping 192.168.1.254 private

    2. the default time before the next generation of new key is normally 28800 seconds, and if there is no interesting traffic flowing between 2 subnets, he'll tear the VPN tunnel down. As soon as there is interesting traffic, the VPN tunnel will be built automatically into the next generation of new key. However, if there is traffic before generating a new key, the new tunnel will be established, and VPN tunnel will remain standing and continue encrypt and decrypt traffic.

    Currently, your configuration has been defined with ITS lifetime of 3600 seconds GOLD / 4608000 kilobytes of traffic before the next generate a new key (it will be either 3600 seconds, or 4608000 kilobytes period expires first). You can certainly change it by default to 28800 seconds without configuring kilobytes. SA life is negotiated between the ASA and Juniper, and whatever is the lowest value will be used.

    Hope that helps.

  • 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.

  • Internet through a RA IPSec VPN Tunnel traffic

    Armed with an ASA 5505 Security Plus, I configure IPSec VPN for RA the VPN IP address pool is in the 192.168.2.0/28 network.

    The Lan is 192.168.1.0/24 with inside interface a.254.

    The VPN works great. What I would do is to route all internet through the firewall traffic when users are connected to the VPN. I put this gateway 192.168.1.254 tunnel, but I'm having no luck to get it works.

    Any ideas?

    Thanks in advance!

    You are just going to route internet traffic to the remote vpn client to the ASA and backward on the Internet?

    If the above statement is correct, you need not configure the tunnel default gateway.

    But you need to configure NAT for the ip pool, so they can go to the internet, as well as the 'same-security-movement' command as follows:

    NAT (outside) 1 192.168.2.0 255.255.255.0

    permit same-security-traffic intra-interface

    In addition, assuming that you have not have split configured tunnel.

  • VPN, Internet and a Split Tunnels traffic

    Please attached photo because I hope that explains what I really want to do, but here's the break down.

    When a VPN Client connects to remote access to 1-ASA5510 I want all Internet traffic to send to 2 - ASA5510 instead of back to the default route. When it comes out 2-ASA5510, it passes through the content filter. 2 - ASA5510 has Split Tunnel put in place and we are trying to do away with Tunnel from SPlit.

    I hope this is clear enough.

    Any ideas would be helpful

    Dan

    Dan,

    Difficult but doable! First of all, there is a nice feature in the ASA that allows configuration of remote proxy based on VPN profile by: -.

    Group Policy <> attributes

    use a MSIE-proxy-server method

    Internet Explorer-proxy server value x.x.x.x

    activate Internet Explorer-proxy local-bypass

    Well Yes you guessed it - works only on Microsoft Internet Explorer.

    I don't think that any policy based routing would work for you - bad luck.

    But you can try another feature - traffic through the tunnel, which is normally used in the topllogy of EasyVPN: -.

    Configuration of the ASA at the bottom, I probably would test this with the IP address of the 2651 router!

  • Site to site VPN, I need all internet traffic to exit the site.

    I have 2 sites connected via a pair of SRX5308

    A = 192.168.1.0/24

    IP WAN = 1.1.1.1

    B = 192.168.2.0/24

    IP WAN = 2.2.2.2

    Now what I need to do, is to have all traffic from B to go to the site one even traffic destined to the internet. That is, I need internet traffic out of our network with the IP 1.1.1.1, even if it is from the network B.

    On my I have set up a route 1.1.1.1 of the ISP, then a value by default 0/0 to 192.168.1.1 it ASA knows how to get to the peer VPN is a more specific route, but sends everything above the tunnel, at the remote end which then hairpin of ASA routes internet outside its own WAN port traffic.

    I can understand though not how to so the same thing on the pair of SRX5308 they either don't raise the tunnel or internet route to the local site address B.

    Anyone have any ideas?

    I need to do this because we are logging and monitoring of internet traffic to A site via tapping from upstream to various IDS solutions and will not (cannot) reproduce this to all our remote sites.

    Thank you

    Dave.

    After some more thought and testing I came up with a workable solution to my own problem. I'll share it here in case it can help others.

    (1) use the wizard at both ends to implement a normal VPN that connects the two segments of network 192.168.1.0 and 192.168.2.0

    (2) go to site VPN - VPN policy remote router192.168.2.1 and click Edit

    (a) disable Netbios

    (b) select "None" from the drop-down list the remote IP address.

    (c) to apply the change

    3) go to the VPN-> VPN policy on the head end site (192.168.1.1) and click Edit

    (a) disable Netbios

    (b) select "None" from the drop-down list the local IP address

    (c) to apply the change

    Now all the traffic wil go down the VPN tunnel and exit to the internet on the site of head end. Hope this helps others with the same question.

  • Windows - Internet access, no split Tunnel L2TP VPN Clients does not

    Greetings!

    I have four ASA 5505 that I configured with 4 site to site VPN tunnels (works perfectly) to connect to our company facilities 4. The ASA is also configured with remote access L2TP/IPsec so that a specific group of users of portable computers can connect to and access to all facilities. It also works very well except for one important exception - my split tunnel setting doesn't seem to work, because I can't connect to the Internet outside the VPN resources.

    I accept the inherent risk of allowing tunnels to split from a security point of view since I take the necessary steps to secure the systems used for remote access. I would appreciate any feedback on how to get the job of split tunnel.

    I should also mention that my test clients are a combination of Windows XP, Windows 7, and Windows Mobile. Other that in specifying the preshared key and forcing L2TP/IPsec on the client side, the VPN settings on clients are the default settings with the help of MS-CHAP/MS-CHAPv2.

    You must configure * intercept-dhcp enable * in your group strategy:

  • problem of traffic flow with tunnel created the network with a tunnel to a VPN concentrator

    Hi, I worked with Cisco and the seller for 2 weeks on this.II am hoping that what we are witnessing will ring a Bell with someone.

    Some basic information:

    I work at a seller who needs from one site to the other tunnel.  There are currently 1 site to another with the seller using a Juniper SSG, which works without incident in my system.  I'm transitioning to routers Cisco 2811 and put in place a new tunnel with the seller for the 2800 uses a different public ip address in my address range.  So my network has 2 tunnels with the provider that uses a Cisco VPN concentrator.  The hosts behind the tunnel use 20x.x.x.x public IP addresses.

    My Cisco router will create a tunnel, but I can't not to hosts on the network of the provider through the Cisco 2811, but I can't get through the tunnel of Juniper.  The seller sees my packages and provider host meets them and sends them to the tunnel.  They never reach the external interface on my Cisco router.

    I'm from the external interface so that my endpoint and the peers are the same IP address.  (note, I tried to do a static NAT and have an address of tunnel and my different host to the same result.)  Cisco has confirmed that I do have 2 addresses different and this configuration was a success with the creation of another successful tunnels toa different network.)

    I tested this configuration on a network of transit area before moving the router to the production network and my Cisco 2811 has managed to create the tunnel and ping the inside host.  Once we moved the router at camp, we can no longer ping on the host behind the seller tunnel.   The seller assured me that the tunnel setting is exactly the same, and he sees his host to send traffic to the tunnel.  The seller seems well versed with the VPN concentrator and manages connections for many customers successfully.

    The seller has a second VPN concentrator on a separate network and I can connect to this VPN concentrator with success of the Cisco 2811 who is having problems with the hub, which has also a tunnel with Gin.

    Here is what we have done so far:

    (1) confirm the config with the help of Cisco 2811.  The tunnel is up.  SH cyrpto ipa wristwatch tunnel upward.
    (2) turn on Nat - T side of the tunnel VPN landscapers
    (3) confirm that the traffic flows properly a tunnel on another network (which would indicate that the Cisco config is ok)
    (4) successfully, tunnel and reach a different configuration hosting
    (5) to confirm all the settings of tunnel with the seller
    (6) the seller confirmed that his side host has no way and that it points to the default gateway
    (7) to rebuild the tunnel from scratch
    8) confirm with our ISP that no way divert traffic elsewhere.  My gateway lSP sees my directly connected external address.
    (9) confirm that the ACL matches with the seller
    (10) I can't get the Juniper because he is in production and in constant use

    Is there a known issue with the help of a VPN concentrator to connect to 2 tunnels on the same 28 network range?

    Options or ideas are welcome.  I had countless sessions with Cisco webex, but do not have access to the hub of the seller.  I can forward suggestions.

    Here's a code

    OK - so I have messed around the lab for 20 minutes and came up with the below (ip are IP test:-)

    (4) ip nat pool crypto-nat 10.1.1.1 10.1.1.1 prefix length 30 <> it comes to the new address of NAT

    !
    (1) ip nat inside source list 102 interface FastEthernet0/0 overload <> it comes to the interface by default NAT

    !
    IP nat inside source map route overload of crypto-nat of crypto-nat pool <> it is the policy of the NAT function

    !

    (6) access-list 101 permit ip 172.16.1.0 0.0.0.255 172.16.2.0 0.0.0.255 <> defines the IP source and destination traffic

    !

    (2) access-list 102 deny ip 172.16.1.0 0.0.0.255 172.16.2.0 0.0.0.255 <> does not NAT the normal communication

    (3) access-list 102 deny ip 10.1.1.1 host 172.16.2.0 0.0.0.255 <> does not re - NAT NAT

    (1) access-list 102 permit ip 172.16.1.0 0.0.0.255 any <> allows everyone else to use the IP Address of the interface for NAT

    !

    (5) crypto-nat route-map permit 5 <> condition for the specific required NAT
    corresponds to the IP 101 <> game of traffic source and destination IP must be NAT'td

    (7) access list 103 permit ip 10.1.1.1 host 172.16.2.0 0.0.0.255 <> crypto acl

    Then, how the works above, when a package with the what IP 172.16.1.0/24 source wants to leave the router to connect to google, say the source will change to IP interface (1).  When 172.16.1.0/24 wants to talk to172.16.2.0/24, it does not get translated (2).  When the remote end traffic equaled the following clause of NAT - the already NAT'td IP will not be affected again (3) when a host 172.16.1.0/24 wants to communicate with 172.16.2.20/24 we need a NAT NAT specific pool is required (4).  We must define a method of specific traffic to apply the NAT with a roadmap (5) which applies only when the specific traffic (6), then simply define the interesting traffic to the VPN to initiate and enable comms (7) corresponding
