• PIX 515E (7.0.1) - problem with the VPN connection between inside and outside

  Hello

  I ve creates a VLAN on the pix.

  In this VLAN, users are allowed to connect only to the Internet. Everything is fine, but when trying to connect with his VPN Client to their company, it has problems... (Outside traffic flow, but no traffic came back.)

  Is the only solution for this problem to create a Pool of Nat with public ip addresses, one to one mapping, or is there another solution with a public IP address (NAT on PAT) possible for this problem?

  Thanks for your replies.

  D.

  The problem is that the esp is an IP Protocol, so PAT will not work in this scenario. When the return traffic returns to pix he doesn't know how to get to the inside host. The only way to do this is by adding a static nat (1 to 1 mapping) and create a rule to allow esp. Is what type of vpn client? Microsoft vpn? Cisco vpn? If cisco VPN, perhaps, they can use NAT - T on the vpn that overcomes the question PAT by encapsulating ipsec within UDP packets. You need to talk to the admin VPN and itself it allow.

  I want to create an ipsec vpn, my question is that I can combine several subnets of headquarters in a subnet because I want ot get rid of several ACL entries

  Hello

  Well, if we look at the site of the Directorate. He has only the single network and even with the destination network that overlap, it shouldn't be a problem. If a host on the network of agencies needs to connect to another host to local subnets will connect directly to him and the traffic flow through the router.

  I don't know if there should be no problem on the PIX side or the other.

  But to be honest, it's a very small amount of networks, and I don't see a particular reason, that I would not configure each network specifically, even if it should procude a few lines more to the ACL. Personally, I prefer to be as specific as possible in configurations to avoid any problems.

• Subnet VPN IPSec problem

  Hello

  I am configuring site to site connection using the pre-shared key VPN. The VPN connection is getting up and running, but I'm having problems on information routing between subnets.

  Our subnet is 192.168.1.0 and we cannot use that subnet for VPN. Because of this, we use 10.240.86.33 for are created the IPSec traffic and destination network (PC) is on 164.2.107.56.

  Hello

  It is the router that ends the VPN tunnel? (I don't see the VPN configuration).

  Since you can't use your real address LAN, you need to NAT before you send the traffic through the tunnel.

  First, you apply the NAT rule to translate 192.168.1.0/24 to 10.240.86.33 when you go to 164.2.107.56

  NAT 192.168.1.0 ip access list allow 0.0.0.255 host 164.2.107.56

  NAT route map

  corresponds to the IP NAT

  IP pool local VPNPool 10.240.86.33 10.240.86.33

  IP nat inside source overload map route NAT pool VPNPool

  Next, you create the ACL list for interesting traffic to address coordinated at the address of the site to another

  VPN ip host 10.240.86.33 access list permit 164.2.107.56

  We will see the results.

• Impossible to access all subnets when connected by VPN

  I'm a total newbie when it comes to cisco and routing, so forgive me if this has been answered before.

  We have a cisco 2821 router which supports VPN connections. Our local network is a 22 (255.255.252.0) xxx.xxx.0.0 xxx.xxx.1.0 xxx.xxx.2.0 xxx.xxx.3.0 subnets. I can connect by VPN, and I can access my xxx.xxx.1.0 subnet with no problems. However, I can't access the subnets xxx.xxx.2.0 and xxx.xxx.3.0.

  I don't know even where to start. I have seen similar topics but I need "dumbed down" for me. Preference of the solutions that I can apply through the SDM. I'm terrible with the CLS.

  Thanks for any help provided! :-)

  It's here

  access-list 199 permit ip 10.1.0.0 0.0.1.255 10.1.255.0 0.0.0.255

  your customers receive the address pool of 10.1.255.0 0.0.0.255

  to allow access to any other network in your local network from the vpn client

  access-list 199 permit ip 10.1.255.0 0.0.0.255

  You must add the same lines that you add in the 199 ACL ACL 104 but with the action to refuse since you are using nat

  104 refuse 10.1.0.0 ip access-list 0.0.1.255 10.1.255.0 0.0.0.255

  Notice that you use a deny and that is to tell the router to do no. NAT traffic.

  I hope that helps... Let me know

• VPN connection problem: keep connection

  I'm having a problem with the maintenance of VPN connection. I connect okay but the line VPN disconnects after about 2 minutes each time.  I use XP Professional V2002, Service Pack 3.  I have disabled the WIndows firewall, as I have F-Secure software suite with its active firewall.  I connect laptop wireless via a Belkin router.  I had no problem for months up until August when suddenly this problem appeared.  I have disabled firewall F-secure, but that did not help. I also disabled the firewall on the router, but again without success.  Can you please help?

• ASA 5505 ASDM VPN connection problem

  Hello

  We are running a version of firewall ASA 5505 8.4 (4) 1. The ASDM version is 6.4 (9).

  The problem is when the creation of remote access VPN connection, it works fine for about 2-3 days.

  After that, the VPN client cannot connect more and gives the error code 789.

  In this case, the VPN clients are clients of Windows 7 from different remote networks with the same problem scenario.

  Windows 8.1 clients cannot connect at all and show the same error code...

  All connections go through the keys defaultragroup and preshare match on both sides.

  When the user to connect attemps I receive the following text in the log of the ASDM:

  6 April 10, 2015 10:52:39 group = DefaultL2LGroup, IP = 5.240.31.116, P1 retransmit msg sent to the WSF MM
   
  5 April 10, 2015 10:52:39 group = DefaultL2LGroup, IP = 5.240.31.116, in double Phase 1 detected package.  Retransmit the last packet.
   
  5 April 10, 2015 10:53:03 IP = 5.240.31.116, encrypted packet received with any HIS correspondent, drop
   
  When I implemented the remote login through ASDM I followed the instructions according to the following link:
  http://www.databasemart.com/HOWTO/Cisco_VPN_Remote_Access_Setup_ASA5500...
   
  The steps were a little different, but almost the same, given that these instructions show an old version
   
  I'm interested in trying the steps according to this link but not sure this will help me solve the problem id:

• I'm having a problem when I try to establish a VPN connection

  I have a problem when I try to establish a VPN connection between a remote computer and my desktop computer that we use as a file server in our network of workplaces. It has a static IP address. The VPN connection was working until the person on the other side you have forgotten the password. We decided to set up a new connection with the new user name and password. The remote computer could not establish a VPN connection with the server, but when the person on the other side tried to open the files, she received a message indicating there is no permission to do so. I can't understand how to give the person permission to open folders. Can anyone help?

• Coming out of the IPSec VPN connection behind Pix535 problem: narrowed down for NAT-Associates

  Hello world

  Previously, I've seen a similar thread and posted my troubles with the outbound VPN connections inside that thread:

  https://supportforums.Cisco.com/message/3688980#3688980

  I had the great help but unfortunatedly my problem is a little different and connection problem.  Here, I summarize once again our configurations:

  hostname pix535 8.0 (4)

  all PC here use IP private such as 10.1.0.0/16 by dynamic NAT, we cannot initiate an OUTBOUND IPSec VPN (for example QuickVPN) at our offices, but the reverse (inbound) is very well (we have IPsec working long server /PP2P). I did a few tests of new yesterday which showed that if the PC a static NAT (mapped to a real public IP), outgoing connection VPN is fine; If the same PC has no static NAT (he hides behind the dynamic NAT firewall), outgoing VPN is a no-go (same IP to the same PC), so roughly, I have narrowed down our connection problem VPN is related to NAT, here are a few commands for NAT of our PIX:

  We had this problem of connection VPN IPsec from the years (I first thought it is restriction access problem, but it does not work or if I disable all access lists, experience of yesterday for the same restriction of the access-list shows longer than PC is not the cause). All suggestions and tips are greatly appreciated.

  If anyone has the answer please answer ASAP

  When you say can ping any URL, I am assuming that you are pinging of the FULL domain name, IE: it is resolved to an ip address, right?

  If you disable the VPN, can you access the internet?

  You have a proxy server or anything that could block navigation?

  This error message you get on your web browser?

  Also try another web browser, and none works?

• Security problems of Windows 7 connecting to the VPN to a ras server

  We run a domain for most of our users - but not all - due to the merger of companies

  We use vpn connections from Windows at the standard address to access remotely via a no domain Server 2003 running RSA

  Windows name nigel.hunter@domain-name

  VPN username nhunter

  When runnin Windows xp users can get access to the files on the servers

  When you run Windows 7, they can

  have found that the system windows 7 are passing the VPN user name and credentials instead of the credentials of domain

  This does not prevent access

• VPN connection problems...

  I don't know what is happening or what Miss me...

  I set up a vpn connection to my remote offices with a 5505.  My main office, I have a 5510.

  My remote offices, I can PING my main Office Server.  However, when I go to set up a VPN through windows network sharing Center I can't get the connection to connect...

  Am I doing something wrong or what step am I missing?

  Thank you!!

  Can you try to add this:

  permit same-security-traffic inter-interface
  permit same-security-traffic intra-interface

  I'd put it on two unless you have a reason not to.  If there is no love after that we will break down the pppoe and vpn configuration.

• VPN connection: An unexpected error has occurred.

  I am suddenly unable to get my built-in VPN connection works on my iMac with OS X 10.11.5.  I get the VPN connection message: an unexpected error has occurred.  I have been using this VPN configuration to connect to work for several months with success.

  But last week (and I do not know if it had nothing to do with it), I went on vacation and used a free wi - fi setup of Tim Hortons.  I had a LOT of trouble getting the next login page, and I checked all playing with different settings of network without success.  When a change did not work, I put it to its original setting.  Finally, I learned to use Safari to access the free WiFi connection page of Tim.  Then once connected, everything was OK.

  But when I returned a week later and if necessary, to start my VPN connection to access the work, it wouldn't start.  I checked and recheck all my settings preferably of different network, but did not find those who were wrong.  I even deleted and re-entered my VPN service definition without solving the problem.

  Thinking that the problem could be the newly installed ISP of Bell equipment (we went from Rogers while I was away), I used my BlackBerry smartphone (issued by my employer) to create a wi - fi hotspot and accessed to the internet using this connection which completely ignored my home ISP equipment.  But still, I was unable to establish a VPN connection.

  I then tried my iPad VPN connection, and it worked!  Then, I defined a VPN service on the iMac to my wife and the iMac to my daughter and was able to successfully establish a VPN connection to my work very well, using exactly the same VPN configuration.  This led me to the conclusion, it was a problem on my iMac (and not with my new ISP or VPN system of my work that had none of the changes you made), but I still can't find what is "broken".  I run Onyx for my iMac OS X 10.11.5 and repaired permissions and clean the cache and all the rest she is doing to "solve" problems.  But the problem persisted.

  Is there a preference file corrupted somewhere (scan option is no longer on the current version of the Onyx for a reason any)?

  I still have a network setting wrong somewhere I need to go back to the system is correct value?

  Here is the attempt to VPN from the file system.log (with some hidden values in the case where they display my work VPN access):

  I finally found my VPN problem.

  There is a 'racoon' file that is generated when I connect to the VPN to my work site.

  I have created a modified version of this file so that my connection does not expire in 3600 seconds (changed in 24 hours).

  Apparently, there are some slightly different settings (such as certain IP addresses other than VPN IP of my work) in this file under our new ISP Bell from the former FAI Rogers.

  And if I connect to the WiFi Hotspot from my BlackBerry, it does not once again because these settings in the file are different again.  I must return the file generated instead of my modified file.

  Bad luck!

• VPN connections disappear, RASDIAL makes reappear

  Here is a screenshot of the connect to a network dialog box. Notice that my VPN connection is not displayed. Nothing shows the:

  http://i44.Tinypic.com/2iu3rpg.jpg

  In order to get the dialog box to regain his senses, I drop simply to an elevated command prompt and run

  rasdial [name of the VPN connection]
  You don't need credentials. You don't need it to sucessfully connect; You just push with a stick rasdial:

  The connect to a network dialog box now works:

  http://i40.Tinypic.com/qpqd6h.jpg

  You can see screenshots of Windows Vista. I saw this bug on Windows XP.

  My question is: How can I get Microsoft repaired?

  Hi Jack,

  Well, Gack! If it happens only every several weeks to months, it will be very fun in the not so fun sort of way to track down.

  Here is my point of view.

  First of all, on a side note, I would never, ever use Windows without an antivirus package, if you go on the internet at all, which you seem to do.

  'Common sense' has worked well before the age of the car by possible viruses. Just go for a page (even supposed to known good) can give you an infection. I'm not saying it's likely, all easily possible.

  I highly recommend that you run some virus scans (these forums have several good suggestions) just to be sure, but it doesn't sound like you have a virus to me.

  Well, I'll get off my soap box now. :-)

  Then, restart is a standard "fix." If this solves the problem, then virtually all support guys in the world are going to tell you, "there is difficulty, have a nice day." I won't argue your point well, it is wrong. Just please realize that there are literally billions of combinations possible, hardware and software. There is no way that each of them could possibly work together without problem. I'll just tell you that it is a workaround and you should use if it works.

  Finally, if you want to keep looking for a better solution, I am with you on that. Solutions help all of us.

  So, here's what you can do then.

  When it happens the next time, mark the time.

  Then go into the event viewer and begin to track down any errors at the time, that happened as well as the warnings and all the events that went past just before the problem started. We don't need (or want) the full thing, just the header with the name of event ID, source, journal, and level.

  You should know what happens if anything started, stopped or tried to run or tried to brake.

  Any service which is of what precedes.

  Also, I'm looking more on Technet.

  Since you said that you work, so for now, I'd mark this thread as closed and start again when and if the problem happens again.

  Of course, I hope this helps!

• Once the VPN connection is established, cannot ping or you connect other IP devices

  Try to get a RV016 installed and work so that people can work from home.  You will need to charge customers remote both WIN XP and MAC OS X.

  Have the configured router and works fine with the VPN Linksys client for WIN XP users.  Can connect, ping, mount the shared disks, print to printers to intellectual property, etc.

  Can connect to the router fine with two VPN clients third 3 for Mac: VPN Tracker and IPSecuritas.  However, once the connection is established, cannot ping the VPN LinkSYS router or any other IP address on the LAN Office.  Turn the firewall on or off makes no difference.

  Is there documentation anywhere that describes how the LinksysVPN for Windows Client communicates so these can be replicated in 3rd VPN clients from third parties for the Mac in OS X?

  The connection with IPSecuritas and VPN Tracker is performed using a shared key and a domain name.  It is not a conflict of IP address network between the client and the VPN 192.168.0.0/24 network.

  VPN Tracker and IPSecuritas are able to connect to the routers CISCO easy VPN with no poblem.

  Any ideas on how to get the RV016 to work for non-Windows users?

  We found and fixed the problem, so using VPN Tracker or current IPSecuritas on OS X people have access to the LAN via the RV016 machines. The "remote networks" in the screen BASE in VPN Tracker has been set on the entire subnet: 192.168.0.0/255.255.255.0 the in the RV016 has been set to the IP of 192.168.0.1 to 192.168.0.254 range. Even if the addresses are essentially the same, without specifying the full subnet in the RV016 has allowed the connection to do but prevented the VPN client machine to connect because the RV016 would pass all traffic to the Remote LAN. Change the setting of 'local group' in RV016 settings in the screen "VPN/summary/GroupVPN', 'Local Group Zone' for the subnet 192.168.0.0/24 full solved the problem.
