external access through ipsec site-to-site tunnel

Hi all

I configured n/b site VPN ipsec Cisco ASA5510 router (site1) and router sonicwall (site2).  I can access two LAN subnets.

But what I need is, routing traffic from site2 to a public ip specific to ipsec tunnel and then to internet through router cisco.

I updated the IPSec in sonicwall, so that traffic to this ip address will be routed to ipsec and all other traffic will go through the default gateway (sonicwall).

Then, I watched the packets on ASA5510 router Cisco ASDM and found that the packets intended for that particular ip address reached router cisco.

But still I can't access that intellectual property of site2. I think there must be some rules to allow that IP. And also I do not know it is possible to

access to the internet through the ipsec tunnel. ? I searched a lot and could not find useful advice. And I don't want all internet traffic to ipsec.

Thank you

Hans

It is what some similar to the only difference in the example below, it is the clients vpn access must be provided for users, but in your EAC, internet access is for some ip of an asite at the tunnel site

  • Disable external access

    I have several office pools and want to enable external access through my server security for some users, but not others.  Is there a way to do this?  I want to do it at the user level, but the level of the pool would be nice as well.  Now, everyone can access internal and external...

    Yes you can do it with "restricted rights." There is an article about it in the called Administrator's guide "restrict view Desktop Access. 116 page here http://pubs.vmware.com/view-50/topic/com.vmware.ICbase/PDF/view-50-administration.pdf

    You basically 'tag' your server connection (for example 'external' and 'Internal'). By default, the pools are available for all tags, but you can restrict this and say to specific pools that you want to restrict access to the "Internal" only. In this way they are not available for users accessing the view of remote sites.

  • Client needs to access the devices on the existing site to site tunnels

    Hello and thanks in advance.

    We use ASA5510 in respect to the vpn appliance and currently have 90 + vpn tunnels (site to site tunnels) ipsec connected to this ASA.

    Recently, we configure a tunnel for one of our customers (site in tunnel).

    Now, this client must have access at least 10 existing tunnels a site that I have.

    They must be able to access the devices on this segment.

    How should I proceed with this application?

    Can I update all existing tunnels site at 10 to add this range of ip addresses of places (clients)?

    Yes, you need to add this new subnet as interesting traffic on all 10 tunnels (on card crypto ACL) If you need two-way communication.

    Kind regards

  • Tunnel of IPSec site to Site - port-based ACL

    I saw crypto that ACLs will be created but still allowing all (IP).

    What happens if I want to allow hosts on siteA to only access servers in siteB web. In this scenario, I only want to allow port 80 to reach hosts on the siteA. Is this possible? is based on the port ACL allow site to site tunnels?

  • Troubleshooting IPSec Site to Site VPN between ASA and 1841

    Hi all

    in the past I've implemented several VPN connections between the devices of the SAA. So I thought a site link between an ASA site and 1841 would be easier... But it seems I was mistaken.

    I configured a VPN Site to Site, as it has been described in the Document ID: SDM 110198: IPsec Site to Site VPN between ASA/PIX and an example of IOS Router Configuration (I have not used SDM but CCP).

    I have run the wizards on the ASA with ASDM and the current IOS version 15.1 1841, with CCP.

    It seems to Phase 1 and 2 are coming although my ASA in ADSM reports (monitoring > VPN > VPN statistics > Sessions) a tunnel established with some of the Tx traffic but 0 Rx traffic),

    On the ASA:

    It seems that the routing on the 1841 is working properly as I can tear down the tunnel and relaunch in scathing a host on the network of 1841, but not vice versa.

    Joerg,

    ASA receives not all VPN packages because IOS does not send anything.

    Try to send packets to the 1841 LAN to LAN of the ASA and see is the "sh cry ips its" on the 1841 increments the encrypted packets (there not)

    The problem seems so on the side of the router.

    I think that is a routing problem, but you only have one default gateway (no other channels on the router).

    The ACL 100 is set to encrypt the traffic between the two subnets.

    It seems that the ACL 101 is also bypassing NAT for VPN traffic.

    Follow these steps:

    Try running traffic of LAN router inside IP (source of ping 192.168.37.x 172.20.2.254) and see if the packages are not through the translation and obtaining encrypted.

    I would also like to delete 100 ACL from the inside interface on the router because it is used for the VPN. You can create an another ACL to apply to the interface.

  • Routing of traffic between two VPN Site-to-Site Tunnels

    Hi people,

    I am trying to establish routing between two vpn Site-to-Site tunnels which are destined for the same outside the interface of my Cisco ASA.

    Please find attached flowchart for the same thing. All used firewalls are Cisco ASA 5520.

    Two VPN tunnels between Point A and Point B, Point B and Point C is too much upward. I activated same command to permit security level interface also intra.

    How can I activate the LAN subnets traffic behind Point to join LAN subnets behind C Point without having to create a tunnel separated between Point A and Point C

    Thank you very much.

    Hello

    Basically, you will need to NAT0 and VPN rules on each site to allow this traffic.

    I think that the configurations should look something like below. Naturally you will already probably a NAT0 configuration and certainly the L2L VPN configuration

    Site has

    access-list NAT0 note NAT0 rule for SiteA SiteC traffic

    access-list allowed NAT0 ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0

    NAT (inside) 0 access-list NAT0

    Note L2L-VPN-CRYPTO-SITEB access-list interesting traffic for SiteA to SiteC

    access-list L2L-VPN-CRYPTO-SITEB permit ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0

    Where

    • NAT0 = is the ACL to be used in the NAT0 rules that will exempt SiteA SiteC NAT traffic
    • NAT = is the line of configuration NAT0
    • L2l-VPN-CRYPTO-SITEB = LCA in configurations VPN L2L that defines the SiteA LAN to LAN SiteC traffic must use the VPN L2L existing SiteB

    Site B

    access list OUTSIDE-NAT0 note NAT0 rule for SiteA SiteC traffic

    OUTSIDE-NAT0 allowed 192.168.1.0 ip access list 255.255.255.0 192.168.3.0 255.255.255.0

    NAT (outside) 0-list of access OUTSIDE-NAT0

    Note L2L-VPN-CRYPTO-SITEA access-list traffic for SiteA to SiteC through a Tunnel between A - B

    access-list L2L-VPN-CRYPTO-SITEA ip 192.168.3.0 allow 255.255.255.0 192.168.1.0 255.255.255.0

    Note L2L-VPN-CRYPTO-SITEC access-list traffic for SiteA to SiteC through a Tunnel between B - C

    access-list L2L-VPN-CRYPTO-SITEC permit ip 192.168.1.0 255.255.255.0 192.168.3.0 255.255.255.0

    Where

    • OUTSIDE-NAT0 = is the ACL to be used in the NAT0 rules that will exempt SiteA SiteC NAT traffic. It is this time tied to the 'outer' interface, as traffic will be coming in and out through this interface to SiteB
    • NAT = is the line of configuration NAT0
    • L2l-VPN-CRYPTO-SITEA (and SITEC) = are the ACL in the configurations of VPN L2L that defines the SiteA LAN to LAN SiteC traffic should use existing VPN L2L connections.

    Site C

    access-list NAT0 note NAT0 rule for SiteC SiteA traffic

    NAT0 192.168.3.0 ip access list allow 255.255.255.0 192.168.1.0 255.255.255.0

    NAT (inside) 0 access-list NAT0

    Note list-access-L2L-VPN-CRYPTO-SITEB SiteC to SiteA interesting traffic

    L2L-VPN-CRYPTO-SITEB 192.168.3.0 ip access list allow 255.255.255.0 192.168.1.0 255.255.255.0

    Where

    • NAT0 = is the ACL to be used in the NAT0 rules that will exempt SiteC to SiteA NAT traffic
    • NAT = is the line of configuration NAT0
    • L2l-VPN-CRYPTO-SITEB = LCA in configurations VPN L2L that defines the SiteC LAN to LAN SiteA traffic must use the VPN L2L existing SiteB

    To my knowledge, the foregoing must manage the selection NAT0 and traffic for VPN L2L connections. Naturally, the Interface/ACL names may be different depending on your current configuration.

    Hope this helps

  • IPSec site to site VPN cisco VPN client routing problem and

    Hello

    I'm really stuck with the configuration of ipsec site to site vpn (hub to spoke, multiple rays) with cisco vpn remote client access to this vpn.

    The problem is with remote access - cisco vpn client access - I can communicate with hub lan - but I need also communication of all lans speaks of the cisco vpn client.

    There are on the shelves, there is no material used cisco - routers DLINK.

    Someone told me that it is possible to use NAT to translate remote access IP-lan-HUB customers and thus allow communication - but I'm unable to set up and operate.

    Can someone help me please?

    How the DLINK has been configured for traffic between the site to site VPN subnets? You are able to add multiple remote subnets on DLINK? If you can, then you must add the pool of Client VPN subnet.

    Alternatively, if you cannot add multiple subnet on DLINK router, you can change the pool of Client VPN 192.168.6.0/24, and on the crypto ACL between the site to site VPN, you must edit the 180 existing ACL

    DE:

    access-list 180 allow ip 192.168.7.0 0.0.0.255 192.168.1.0 0.0.0.255

    access-list 180 allow ip 192.168.200.0 0.0.0.255 192.168.1.0 0.0.0.255

    TO:

    access-list 180 allow ip 192.168.6.0 0.0.1.255 192.168.1.0 0.0.0.255

    Also change the ACL 190 split tunnel:

    DE:

    access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.200.0 0.0.0.255

    access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.200.0 0.0.0.255

    TO:

    access-list 190 allow ip 192.168.7.0 0.0.0.255 192.168.6.0 0.0.0.255

    access-list 190 allow ip 192.168.1.0 0.0.0.255 192.168.6.0 0.0.0.255

    Finally, replace the remote subnet 192.168.7.0/255.255.255.0 192.168.6.0/255.255.254.0 DLINK.

    Hope that helps.

  • Failed to configure two AnyConnect & IPSEC site to site VPN

    I have established a VPN IPSEC site-to-site

    When I configure the AnyConnect (make it work) and I lose the tunnel from site to site and vice versa.

    I think that my NAT syatements are incorrect.

    Here is the config NAT when AnyConnect works properly...

    Overall (101 outside interface)
    NAT (inside) 0-list of access sslnonat
    NAT (inside) 101 0.0.0.0 0.0.0.0

    access extensive list ip 192.168.65.0 sslnonat allow 255.255.255.0 192.168.66.0 255.255.255.0

    When the IPSEC tunnel site-to-site work properly, here's the NAT config...

    Overall (101 outside interface)
    NAT (inside) 0-list of access Inside_nat0_outbound
    NAT (inside) 101 0.0.0.0 0.0.0.0

    Access extensive list ip 192.168.65.0 Inside_nat0_outbound allow 255.255.255.0 ServerGroup object-group

    How do I get to the AnyConnect and the IPSEC Site to site both to work properly? I need not reach on the other.

    Network within 192.168.65.0/24

    AnyCOnnect address pool 192.168.66.0/24

    Any help would be appreciated.

    Hello

    Try this:

    Overall (101 outside interface)
    NAT (inside) 0-list of access Inside_nat0_outbound
    NAT (inside) 101 0.0.0.0 0.0.0.0

    Access extensive list ip 192.168.65.0 Inside_nat0_outbound allow 255.255.255.0 ServerGroup object-group
    Access extensive list ip 192.168.65.0 Inside_nat0_outbound allow 255.255.255.0 192.168.66.0 255.255.255.0

    The problem is that when you apply the IPsec NAT configuration, you remove the entry for the AnyConnect pool.
    Try the above and we will see if it works.

  • Impossible to get to the beach for additional IP addresses on IPSec Site to Site VPN

    Hello
    I am trying to set up a free IPSec Site to Site VPN between an ASA 5510 (ASA Version 8.2 (3)) to the AC and a Cisco 877 (12.4 (24) T3) to a branch.

    At the end of the branch, I have the 192.168.244.0/24 subnet.
    At the end of HQ, I have the 172.16.0.0/22 and the 10.0.0.0/8 subnets
    The inside interface of the ASA at Headquarters is 172.16.0.15/22

    When installing VPN Wizard I ticked the box NAT - T, and I included the additional subnet in the list of protected LANs.

    I can sucessfully all the subnets 172.16.0.0/22 but not access anything in the 10.0.0.0/8 subnets.
    The Packet Trace ASA tool shows the traffic inside the interface of 172.16.0.0/22 in the direction of 192.168.244.0/24 through the outside interface properly spend, but the 10.0.0.0/8 does not work. He gives no precise information why the 10.0.0.0/8 traffic is dropped.

    [HQ_LAN]---10.0.0.0/8 & 172.16.0.0/22---172.16.0.15(inside_int)-[ASA 5510] - IPSEC-[RTR 877]---192.168.244.0/24---[BRANCH_LAN]

    I suspect it might have something to do with NAT?

    Help, please.

  • I get a message that says: "this connection is not approved" whenever I try to access ANY Web site

    I looked through previous questions and remove any software suspicious (it was not really, just a Bing bar). I deleted firefox and reloaded it. I bought Norton Antivirus and ran a scan - nothing. Date and time on my computer are correct. Explorer works very well. Help! I prefer firefox, but I can't access ANY Web site. I get this message every time.

    I've been down all the instructions on the Firefox support forum, and nothing has worked. The question may not be the Web site certificate, because it happens to EVERY SINGLE website I try to access. Nevertheless, I have add an exception for Facebook according to the instructions. That caused a strange page, not formatted to come. Since, I have read that to make an exception is dangerous because it can cause MORE unwanted malware to infect the computer.

    However, I did figure it out on my own so maybe this will help those who are facing this problem in the future: after reading the past messages from those who have experienced the same thing, I realized that, in all cases, the solution was to remove some kind of unwanted software (malware). I'm very careful NOT to download the software and I noticed that another victim of this says the same thing, so it's sneaky. I even bought new software (Norton) antivirus, performed a scan and the problem has not been found.

    I went to programs "to uninstall programs," sorted by date and anything that looked suspicious that was recently removed. I had something with the word "rocket" in it. It looked like a game. There is also another program that I removed (don't remember the name of it now). Removing those does not solve the problem, so I returned through all programs on my list and removed something that said "toolbar" on this topic, even if it was reliable (I had a bing and google toolbar). That doesn't seem to work either so I sort the programs by date again and I noticed that the software "rocket" was ALWAYS THERE.

    I have a click with the right on it and then click on 'uninstall' button again. It takes unusually LONG for this program uninstall AND nothing appears on the screen. The computer has just sort of is there and does nothing. I left and when I came back (about an hour later) the program had disappeared from the list.

    Firefox now works. I no longer receive this message, but here's the deal: I'm not 100% sure what program was the problem. It was this software of rocket or one of the toolbars. Nevertheless, the answer always seems to be some kind of unwanted malware, so I recommend that any victim of this problem try to uninstall the suspicious programs initially. And this means that ALL suspicious programs are RECENT, regardless of if they resemble games or antivirus or another. If it is new and you do not download it, uninstall it.

  • Web searches are redirected to OpenDNS. Cannot access these Web sites.

    This problem just started. Whenever I try to load a page (in this case Gamefaqs), I get redirected to this search engine called openDNS, saying that the site is not available. It has a link to the site, and whenever I clicked, it redirects me to this thing OpenDNS.

    I tried loading the page with the default browser of chrome on this phone, but also my laptop using firefox and chrome and have not experienced this problem. Yet the problem persists when you try to access the mobile site through firefox.

    I have tried clearing the cache, uninstall and reinstalling, yet the problem isn't resolved. I have done a virus scan, thinking it might be some form of malware that is hijacking my search engine. That all comes back clean.

    I've never heard of OpenDNS, nor have I allowed it to become my search engine. When I go into the settings of search engine, it does not appear, but he manages to keep hijacking of my searches on google and redirect me sites that work normally.

    Please help me.

    Hi SuperRup91, I was able to reproduce this problem on Firefox Mobile on a wi - fi network using OpenDNS. Queries for a single word for non-existent domains + by pressing the arrow go back a page of results of OpenDNS. Typing a search suggestion next to the icon of Google for the word, or by using a query of several given word of Google results. Unless you can change to a different DNS provider, I think you may be stuck with these options.
