Site to Site VPN FIPS 140-2

Need advice/suggestions on conform to the standard FIPS-140, I configured IPSEC VPN tunnels between routers C2811 and passing traffic unclassified by using encryption, 3DES and SHA MD5 and password shared and mode of transport. Thanks for any help

Hi Steve,.

This link will provide you with information about the complicant FIPS algorithms for encryption for theIPSec vpn tunnel:

http://csrc.nist.gov/groups/STM/CMVp/documents/140-1/140sp/140sp1038.PDF

(See section 3.3, IPsec and encryption requirements in the above link)

Following algorithms are not FIPS compatible.

THE
MD-5 for the signature
MD-5 HMAC

Let me know if it gives you the required information.

See you soon,.

  • Unable to pass traffic between ASA Site to Site VPN Tunnel

    Hello

    I have problems passing traffic between two ASA firewall. The VPN tunnel is up with a dynamic IP and static IP address. I have attached a diagram of the VPN connection. I'm not sure where the problem lies and what to check next. I think I have all the roads and in the access lists are needed.

    I've also attached the ASA5505 config and the ASA5510.

    This is the first time that I've set up a VPN connection any guidance would be greatly appreciated.

    Thank you

    Hello

    Regarding your opinion of configuration Remote Site ASA that you have not added the internal networks of the Central Site VPN L2L configurations at all so the traffic does not pass through the VPN.

     access-list outside_1_cryptomap extended permit ip 10.1.1.0 255.255.255.128 10.182.226.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 10.182.226.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 10.182.0.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 192.168.170.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 192.168.172.0 255.255.*.* access-list exempt extended permit ip 10.1.1.0 255.255.255.128 140.15.0.0 255.255.*.*

    Take a look at ACL configurations above. The 'exempt' ACL is used in configurations NAT0 and tells the ASA what traffic of exempting from NAT. "outside_1_cryptomap" ACL is used to tell the traffic between the subnets should be using the L2L VPN connection.

    So in short on the Remote Site ASA these ACLs should be identical. Make additions to the LIST of VPN L2L, then try again.

    I would also like to point out that to ensure that the Central ASAs L2L VPN ACL Site contains the same networks. The ACL on the Central Site will, of course, its internal subnets as the source and the site LAN remote destination.

    THW out of ' crypto ipsec to show his " shows you that only the SA between binding Site Central network and the Remote Site LAN was established. Others have not formed as the configuration is lacking at LEAST on the Remote Site ASA. Can also be the Central Site.

  • Site to Site VPN problem ASA 5505

    Hello

    I have a strange problem with a site to site VPN. I configured it completely and I added 3 of my internal networks to be encrypted and access the remote network across the tunnel.

    For some reason, I can access the remote network of only two of the three internal networkls that I've specified.

    Here is a copy of my config - if anyone has any info I would be happy of course.

    Thank you

    can you confirm if we have the exact reflection of crypto acl at the other end

    I feel may be you have a 24 10.239.192.0 255.255.255.0 on the other end in the remote network

    can you please confirm that

    also a reason, why you use 10.239.192.0 255.255.255.128 and 10.239.192.128 255.255.255.128 instead of 10.239.192.0 255.255.255.0

  • 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!

    Michael

    I suspect that.

    Thank you very much for the reply.

    See you soon!

  • 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.

  • Site to Site VPN on AZURE

    I have a VPN site-to-site existing on Azure and Azure a new subnet created on the local network that must be able to reach.

    I added the new subnet within azure for the VPN and add a static route on the RRAS server win 2012 for routing.

    On the initial installation of a RRAS-Site VPN site (I didn't configure it) I think the interesting traffic specified must be sent through the VPN Tunnel, but I knew how to specify the new subnet via RRAS, I don't want to delete and re-create the VPN Site to Site.

    Y at - there anyone who can help please.

    Thank you

  • IPSec Site to Site VPN Solution needed?

    Hi all

    I need a solution to provide full connectivity to one of my clients. I created two IPSEC Site to Site VPN, one between the INFO and RITA and second between NIDA and RITA. I can access RITA machine that is 172.16.36.101 at the INFO and 10.0.0.5 to NIDA.

    Now, I need to give access to my customer INFORMATION to direct NIDA 10.0.0.5 without established VPN machine to NIDA 10.0.0.5 of 172.16.36.101 access.

    Could you please give me the solution how is that possible?

    Concerning

    Uzair Hussain

    Hi uzair.infotech,

    Looks like you need to set up a grouping between the 3 sites, at the end of that your topology will look like this:

    INFO - RITA - NIDA

    You can check this guide that explains step by step how to configure grouping:

  • Improve SA540 site to site VPN perforamce

    Site has SA540: 50 M / 50 M DSL (country A) (15 users)

    We custom applications and server work on port 80 of services, it comes to legacy applications and need to call the java prompt back.

    We do server on Site A and alos configuration port front of WAN custome application server.

    I find the Site B use direct http services over the Wan just need 5-10 seconds to launch the applaciton

    On the same machine, we use the site to site VPN to connect to the application, that it will take about 15 ~ 20 seconds or more, alos sometimes cannot load success via VPN enforcement, how can I improve it? Or participate in any suggestion that I have to pay?

    Thank you

    Hi yururuhgftdy, your vpn is only as good as the slowest connections. If you want to improve performance, update the connection from the other end.

  • 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:

    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.

    Federico.

  • Remote monitoring Pix on IPSEC site to site VPN

    I have a few 501 s PIX that connect through the VPN site-to site. We use Orion NPM and I can't add monitoring. I was able to add remote routers that connect through site-to-site VPNs. I guess that the rules of the Pix security/NAT prevent that. The configuration of the remote Pix is attached.

    You need on the 2800...

  • Cisco 3640 to the PIX 501 site 2 site VPN performance specifications.

    I intend on creating a site-2-site VPN in Star configuration with a Cisco 3640 as the hub and PIX 501 at the remote sites. My question is around the plug that I read.

    .

    The specifications for a PIX-501-BUN-K9 tell PIX 501 3DES Bundle (chassis, SW, 10 users, 3DES).

    .

    A question is what really "10 users. Which is the limit of the number of concurrent sessions, I have on the VPN at a given time, or that it means something else?

    .

    I also read the specs say that the Maximum number of VPN tunnels that can support a PIX 501 is 5. Because I'm not going to make a tunnel between the PIX 501 at the remote site and the 3640 on the central site, I think I would be OK. Is that correct or is the max value talk the maximum number of concurrent sessions on the tunnel tunnels?

    .

    Thank you.

    UDP traffic always creates a session in the PIX so that the return traffic will be allowed in. The UDP timeout is 2 minutes but IIRC. If you go around NAT with a statement of "nat 0" should not create an xlate I think.

    The real time is hard to say really, probably around 2 minutes for a UDP-only user, you would probably make a few 'local sho' orders on the PIX to really see for sure however.

  • SA520w routing through site-to-site VPN tunnels

    I have several offices that are connected using site-to-site VPN tunnels and all will use the SA520W (firmware 2.1.18). I currently have 3 routers in place, router tunnels created for the router B and c of router. I need assistance with the configuration to allow the guests to router site B get to the router site C. I have attempted to add a static route, but get a destination unreachable host trying to ping. Also, if I connect to the router site has via the Cisco VPN client, I'm not able to get resources on each site, B, or C.

    A - the site 10.10.0.0/24

    Site B - 10.0.0.0/24

    Site of the C - 10.25.0.0/24

    Any help is greatly appreciated.

    So, that's what you have configured correctly?

    RTR_A

    ||

    _____________ || ___________

    ||                                            ||

    RTR_B                                RTR_C

    Since there is no tunnel between B and C there is no way for us past that traffic through RTR_A for two reasons. The most important reason is that subnet 10.25.0.0/24 (rtr_c) is not allowed to pass through the IPSec tunnel (it's okay to IPSec?) of rtr_a ==> rtr_b. You can't just add a statement of road because your addresses are not routable which is the reason why it fails.

    Your only option is to create another tunnel between rtr_b and rtr_c. This may not be the ONLY option, but you should get what you need.

    I hope this helps.
