IPsec on dialup

Hello

I have a network problem which requires a bond secured between places and I think that IPSec will do the job, but I would like some form of guidelines people who know better than I

Problem

PC1 to Site A will send UDP data packets to PC2 to Site B via a dial-up link, occasionally will reply PC2 PC1 again via UDP. PC1 and PC2 are the only systems that pass data over the link.

I intend to have an equipped 2801 analogy modem card (WIC-02:00-V2) at each site and set up the routing of dial-on-demand, IPSec and Firewall but not not to use a VPN.

Is this OK configuration or I missed something?

Thank you

If you need a secured link ecrypted IPSec is the way to go.

I have a feeling that you consider IPSec and VPN as separate things. Usually when configure us IPSec we do to create a VPN connection. So for most terms are fairly interchangeable.

It depends on what set of features of IOS is installed on your router. If it is advanced security or Advanced Services, it will include the software to IPSec. If this is the basis of the IP or the most characteristic IP sets so it doesn't have the ability to run IPSec.

[edit] something else occurs to me talk. IPSec not really don't care what media he travels as long as it has IP connectivity between the 2 IPSec peers. So in this sense IPSec running on remote access should be fine. But assuming that you are talking about normal dialup connection dial will be around down most of the time. When the application tries to send data, it must bring up the dial link. It will initialize, dial and authenticate until he's ready to pass traffic. Then the routers will have to negotiate the ISAKMP Security Associations, then IPSec Security Associations. So there will be some amount of delay before the application traffic begins to flow. Delay create problems with the application?

  • PIX IPSec configuration

    Hello

    We have configured our PIX as below.

    Here, I would like a clarification on implecation access lists.

    I joined 'infinet1' crypto map and 'acl_out' - list access to the external interface, if any traffic entering under "infinet1" of the lists of access such as 101, 102, 103 etc. will again suffer conditions of access 'acl_out"list or not?

    We have seen that this is not the case!

    the conditions of "acl_out" work correctly with the rest of the traffic which is not under the control of IPSec accesses-lists.

    I need to enforce these conditions "acl_out" IPSec traffic too... How can I do?

    The fact that you have:

    > permitted connection ipsec sysopt

    in your config file means that any IPSec packet is allowed in and ignores all the normal safety rules. You can delete this order, but you will then need to add a bunch of lines to your acl_out ACL to ensure that ISAKMP (UDP 500) and IPSec (IP prot 50) are allowed in each peer IPSec individual, more add incoming versions of all your ACL crypto.

  • integrated macOS Sierra Cisco IPsec VPN does not work anymore (impossible to validate the server certificate)

    Hello

    I just upgraded to macOS Sierra and built-in Cisco IPsec VPN no longer works. When you try to connect, I get a "cannot validate the certificate of the server. "Check your settings and try to reconnect" error message. I use Cisco ASA with self-signed certificates and everything worked fine with previous versions of OS X.

    Please help me, I need my VPN Thx a lot

    I am having the same problem with StrongSwan and help cert signed with the channel to complete certificates included in the pkcs12 file imported to the keychain. It was working properly in El Capitan, but now broken in the Sierra.

  • AC100 - no VPN L2TP/IPSec PSK available

    Android 2.2 (Froyo) devices show for VPN connections the following possibilities: PPTP, L2TP, PSK L2TP/IPSec and L2TP/IPSec CRT (checked on several brands of smartphones).

    The AC100 appears only from any PPTP and L2TP, so not L2TP/IPSec.

    No idea why they are missing, and how to fix this?

    Need for L2TP/IPSec to a VPN with a Sonicwall 3060/Pro.

    Here is a description how to connect: [https://www.fuzeqna.com/sonicwallkb/consumer/kbdetail.asp?kbid=8658]

    Hello

    AFAIK the L2TP/IPSec is only available for android devices routed.

    So maybe it's the reason why the L2TP/IPSec in unavailable for AC100.

    I found here a beautiful Android L2TP/IPSec VPN HowTo
    http://blogs.nopcode.org/brainstorm/2010/08/22/Android-l2tpipsec-VPN-mini-HOWTO/

    Maybe it might help a bit!

  • IPsec site to Site VPN on Wi - Fi router

    Hello!

    Can someone tell me if there is a router Netgear Wi - Fi that can form IPsec Site to Site VPN connection between 2 Wi - Fi routers via the WAN connection?

    I know that this feature exists on the Netgear firewall, but can you have the same function on any Wi - Fi router?

    See you soon!

    I suspect that.

  • IPsec over HTTPS

    Is there a way to create an IPSec connection on port 443 (for example if the UDP Port 500 is blocked by outside firewallrules). I noticed some other routers are able, or if it will support on Netgear UTM in futured upgrades?

    Thank you...

    Never. 500 is integrated with IPSec.

    You can use SSL VPN to 443.

    You see what routers supporting VPN IPSec on 443?

  • Cisco IPsec VPN

    Has anyone this configured with the models in the phone and/or imported their own models? Is this even work?

    It happened to be that I was testing with IKE authentication XAuth disable the tunnel group so I didn't have to type a user name and password each time. I decided to activate just to make more apples to apples for my group of main tunnel and put back it in the model. I also took some anti-replay when I was scouring the template that I downloaded here. I also tested it works with RSA authentication, where you put your PIN with the password and then when you want to connect simply add your id to token at the end.

  • Model IPSEC not no projection in web registration

    Nice day

    I have an edition of Windows 2003 R2 Server Standard with a turnover of the company and is an AD DC. My question is... the model of IPEC is not in the drop-down list of web registration.

    The IPSEC model has all the permissions in the Security tab for full control Domain Admins.

    Reason, I need the model IPSEC is that I am creating a site to site ASA VPN using the IKEv2 certificate authentication so I need a certificate of identity.

    Thank you

    Hi Dana,

    I suggest you to ask your question at the following link.

  • IM stops working after a minute or two - troubleshooting explains internet connection problems found (the IPsec negotiation failure prevents the connection)

    Need to patch to get IPsec to start working in Internet instant Mesasenger - I fought this for about 3 months. I can't do a Messenger call for more than a minute before having to re - connect - it's driving me crazy - fix your product - Paul * address email is removed from the privacy *.  Settings information (network security) Diagnostics that can block connections:

    filter name: Messaging microsoft instant - name for the provider context: windows Instant Messenger - provider name: Microsoft Corp.Provider - description: Microsoft Windows Firewall: IPsec provider

    Hi paulrhea,
     
    -What version of the operating system are you using?
    -You are able to go online with no problems?
    -Have you been able to use the Messenger without any problem before?
     
    If you use Windows 7 or Windows Vista, follow the suggestion given here.
     
    Try to disable the firewall for the moment and check if it helps fix the problem.
     

    If the problem is resolved, you may need to contact the manufacturer of the program for the settings that can be changed or if there are other updates for this program.

    Note: Firewall can keep the computer worm, pirates etc. Therefore, be sure to turn on the firewall once you are finished with the test.

    If it is Windows Firewall, see the article below:

  • My computer does not connect to the Internet. Event ID 7003, "the TCP/IP protocol driver service depends on the non-existent service below: IPSec."

    Hello!
    I am working on a Dell Inspiron 1300 laptop for a friend. She has Windows HP Home Edition, SP3 installed.
    He said that Saturday night he started to act funny and wouldn't connect to the Internet. There were a few popups then begins, and he did not know if they were connected to not go on the Internet.
    He had the rootkit.zeroaccess infection. I used Combofix to remove it. It won't always get on the Internet, either via a wi - fi or ethernet connection.
    Looking at the event viewer, I see event ID 7003, "the TCP/IP protocol driver service depends on the non-existent service below: IPSec."
    Then, event 7001, "(NLA) network location awareness service depends on the service protocol driver TCP/IP which could not start due to the following error: the dependency service does not exist or has been marked for deletion.".

    I copied ipsec.sys from another XP Home machine which worked and stuck in the Windows\System32\drivers directory and it still does not work.

    Any ideas are greatly appreciated!

  • Implementation of IPSec Port Forwarding on a Windows 2012 with a LRT224 Server

    Hi all I hope someone can help me validate my troubleshooting. I'm deploying a Server Windows 2012 that will server as a server vpn for customers. In place is a LRT224 with 4 VLANS set up. I have enabled port forwarding for IPSec (UDP/500), L2TP (UDP/1701) and L2TP (UDP/4500) to go on the server.

    In my Initial test, I put the LRT224 on the same network as the client of my test and realized the Test Client (10 Windows) to try to connect to the WAN of the LRT224 interface. I get this message:

    Thinking it could be the configuration of the server, I then put the client system on the same vlan on the LRT224 server. When I tried to connect to it directly by using the IP address of the server as a destination, he succeeded.  It is leading me to believe that it is the LRT224.

    I confirmed that VPN passthrough is enabled.

    The firmware version is by: v1.0.5.03 (February 22, 2016 10:12:17)

    Currently, the firewall is disabled (I would activate once I'm working)

    If anyone has ideas or notice a fault in my tests, I would really appreciate the feedback.

    If additional information would be useful, please let me know what you want and I can work for it.

    Thanks to all in advance.

    It does normally not as I KNOW because the VPN in an outside in the process. You should test the VPN connection outside the server's IP subnet.

    You have the server configuration that the DNS server in the router to DHCP with DNS Proxy is disabled?

    Are you doing load balancing Internet connection?

  • iPsec gateway to gateway on LRT224, main mode?

    Hi, I just got my new Linksys LRT224

    I'm new to Linksys, but have used Netgear, D-Link and routers VPN Redfox.

    About 20 minutes after conversion unboxing of the LRT224 I have an iPsec tunnel of aggressive mode between my Netgear SRX5308 and the LRT224 work, very impressive I think, well not my performance but the ease of LRT224. Very nice interface easy to understand and quick Web. However, I noticed two things so far, 1 I can open only my SRX to the LRT224 tunnel and not vice versa. 2nd I can't get aggressive mode working on LRT224? I do something wrong or does the LRT224 not support the main mode?

    Someone else who tried the main mode?

    (there is no check box to select the main mode, but by selecting the name of domain + IP FQDN on local and remote in aggressive mode is not checked)

    I normally set up routers like this:

    SRX5308 Linksys *.

    IKE:
    General
    Name of the policy = srx5308
    Direction = Both
    Change Mode = hand

    Local:
    FULL DOMAIN NAME
    XXXX.dyndns.org

    Distance:
    FULL DOMAIN NAME
    yyyy.dyndns.org

    IKE SA settings:
    Encryption algorithm = 3DES
    = SHA-1 authentication algorithm
    = Pre-shared key authentication method
    Pre-shared key = MySharedSecret
    The Diffie-Hellman (DH) Group = group 2 (1024 bits)
    HIS life (s) = 28800

    VPN strategy:
    Name of the policy = srx5308
    Remote endpoint point = yyyy.dyndns.org

    Selection of traffic:

    Beach = local IP address
    Start IP 192.168.2.100 =
    End IP = 192.168.2.200

    Beach = remote IP address
    Start IP 192.168.1.100 =
    End IP = 192.168.1.200

    Auto policy settings:
    Life expectancy = 28800 seconds
    Encryption algorithm = 3DES
    = SHA-1 integrity algorithm
    PFS = on
    Key PFS = DH group 2 (1024 bits)
    Selected IKE Policy = srx5308
    ****************************************************************

    Are looking for the forum and also my friend google, but so far have not found anything, so I'll keep looking.

    Hi Ea > Br

    You can try it. Set the parameter to LRT224.

    As below:

    Configuration of the remote control groups:
    Remote security gateway type = IP + authentication with domain name

    Remote IP Type group = IP by DNS resolved:

    XXXX.dyndns.org

    Domain name = xxxx.dyndns.org

    The VPN tunnel will be working on the main mode, and you can open tunnel of LRT224 too.
