• Is there one GUI, other than Assistant Deputy Ministers, and the CSM for test site vpn to ipsec tunnels on an asa5505/asa5510?

  Is there a GUI, other than the Assistant Deputy Ministers and the Security Manager cisco IPSec of Cisco ASA5505/5510 test site to vpn tunnels. I usually go through the steps listed in here in the link below in the terminal window, but it sucks when you have several tunnels to keep abreast of.

  http://www.nwdump.com/troubleshooting-IPSec-VPN-on-ASA/

  I would have preferred one that works with Freebsd or LInux, as the cisco security manager CSM v4.1 is limited to only current running on windows server 2008 ent.

  Thank you

  Jason

  No, for troubleshooting the best way is to use the CLI that will give you debug output on where it is lacking.

  For configuration, outside the CLI, ASDM and CSM, unfortunately there is no other tool that works on Linux/Freebsd because it is more specific orders of the ASA and only limited to the CLI, ASDM, or CSM.

  If this correct what should I configure other side that I want to finish in front of it. Is my address name vpn1 crypto card must match on the other side or not?

  any suggestion is good...

  Thank you...

  What I mean with the routing is a routing protocol or static routes the SAA can choose between interfaces to establish the tunnel.

  If the ASA has the card encryption applied to two interfaces, then one should be used as primary and the other as backup.

  How will be the ASA choose which is better? Via the routing.

  If you use a routing protocol, the ASA will be known which interface to send packets every time, but if using static routes, you need to change the metric and configuring IP SLA.

• Split-DNS for Site to Site VPN

  I'm running into a problem with Server7 unified presence and CUPC on a remote site.  The two sites are connected through a 515E, PIX Firewall (remote) and 525 (principal).  Both executed PIXOS 8.0.4.  The VPN S2S works very well, except there is a problem with the unified Personal Communicator and the presence of the CUPS server to the main site.  Normally, guests at the remote site use a DNS server for their ISP files and hosts for destinations within the main site.  The hosts file does not presence or TFTP etc., to work with the CUPC on remote site.  By temporarily chaning to the DNS server of our DNS servers on the main site, CUPC works perfectly, however, in this scenario, all THE DNS related traffic goes through the VPN, consume too much bandwidth.  I have configured Split DNS on remote access before configs, and they work very well (including CUPC).  Only DNS traffic I want to go through the VPN is DNS queries for hosts within the protected networks (internal resources).  Any ideas on how to achieve this?

  Unfortunately, the same function of split dns is not applicable to the site-to-site vpn. With access remote vpn, configuration is pushed from the server to the client, where the split dns function can be pushed to the client. While in the site to site vpn, there is no configuration that is pushed from one side to the other.

  My recommendation would be to install and configure the local DNS server by replicating the DNS server of your main site, so DNS queries are not sent through the VPN tunnel but is resolved locally. However, this requires a different direction for the local DNS server and DNS of the main site replication.

  Hope that helps.

• Keep Site to Site VPN Tunnel active for monitoring

  Hi all

  I have a configured site-to-site VPN tunnel only happen when the traffic generated from the remote peer. is it possible to keep the still active tunnel once after the tunnel is established.

  My requirement is to monitor VPN to see availability, so need to ping one of the natd(8) ip on the remote end, but it will come only when the traffic generated end peer.  currently the timers of default on SA is configured

  Help, please...

• 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.

  Hello

  Peer VPN you do not accept the LAN between these two peers of vpn segment.

  On your ASA

  inside_outbound_nat0_acl list of allowed ip extended access all <> 255.255.255.0

  and

  Router:

  access-list 100 permit ip 192.168.244.0 0.0.0.255 172.16.0.0 0.0.3.255

  access-list 100 permit ip 192.168.244.0 0.0.0.255 10.0.0.0 0.255.255.255

  Please make the same statement subnet explicitly between two vpn peers and finally please add this route on SAA.

  Same question on this ACL so, statement of not identical subnet between two peers of vpn, please make sure it identical at both ends.

  outside_cryptomap_2 list extended access allowed object-group ip <> <> 255.255.255.0

  Route outside 192.168.244.0 255.255.255.0 ASA_EXTERNAL_GW

  Let me know the result.

• 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 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

• 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.

  Trounleshoot VPN of the 1841 report shows a message like "the following sources are forwarded through the interface card crypto.      (172.20.2.0 1) go to "Configure-> routing" and correct the routing table.

  I have not found an error on the 1841 config so if one of the guys reading this thread has an idea I appreciate highly suspicion!

  It's the running of the 1841 configuration

  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.

• 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.

• Site to Site VPN filter

  I've set up a site to site VPN and I can't seem to get the VPN filter works. I've followed this document:

  http://www.Cisco.com/image/gif/paws/99103/PIX-ASA-VPN-filter.PDF

  I created an ACL and created an ACE with only traffic I want to allow. Then, I went to the site to site group policy and apply this filter. However, I can still ping remote network from a customer who should not be allowed. Remote network is 192.168.2.0/24.Here is my partial config:

  permit Test access extended list ip 192.168.2.0 255.255.255.0 192.168.1.2 host
  Trying to deny a range ip extended access list

  Group Policy internal Test
  Test group policy attributes
  value of VPN-Filter Test

  tunnel-group Test_tunnel type ipsec-l2l
  attributes global-tunnel-group Test_tunnel
  Group Policy - by default-Test

  Hello

  First of all I would like to clarify that the group name used for one site to the other tunnel tunnel must be the ip address of the host "at least for the tunnels l2l static" it's tunnel-g were you must apply this "Test" group policy, configuring the filter seems perfect, but you must make sure that you apply the strategy of Group accordingly. Now, once you apply group policy to the correct you have to bounce the tunnel tunnel-g otherwise the new filter will not take effect, you can use the command "erase the crypto ipsec his counterpart x.x.x.x" generate some traffic and bring up the tunnel is again he should have the filter.

  If you apply correctly and bounce the tunnel it will work.

  You can check if the filter is applied with the command "show vpn-sessiondb detail l2l" and find the name of the ACL

  Best regards, please rate.

• Site to Site VPN Possible behind routers NAT on both ends?

  Nice day

  After extensive research I have not found an answer so I turn to the community.

  I'm trying to help a friend facility a VPN but it's a scenario that I have not dealt and hope that someone has.

  Here's the basic scheme;

  Site 1 - 172.16.23.0/24

  Site 2 - 172.16.24.0/24

  (Site of ASA 1 - router 172.16.23.5) - Linksys w / static public IP - Internet - Linksys router w / static public IP-(ASA Site 2 - 172.16.24.5)

  Is this possible scenario with port forwarding?  The warnings, I need to watch out for?

  I read that I'll need a route to my ASA, say Site 1 ASA, who said... Route 172.16.24.0 255.255.255.0 1.1.1.1 (point to ASA local public IP).

  I also read I'll need one additional lane in my (site 1) linksys router that says... Route 172.16.24.0 255.255.255.0 172.16.23.5 (point to the local interface of the ASA)

  Thanks for all comments and suggestions.

  A

  Hi Adam,.

  You are right with a port forwarding, you can create an IPSEC tunnel, even if NAT is present on both ends.

  Also, NAT - T is a feature enabled by default on the ASA that automatically detects if the camera is behind a NAT and pass the IPSEC UDP 4500 port. Here is the syntax of the command:

  ASA (config) # crypto isakmp nat-traversal 20

  How NAT - T works

  So, here is a document for your reference build the VPN tunnel:

  http://www.Cisco.com/c/en/us/support/docs/security/ASA-5500-x-series-next-generation-firewalls/119141-configure-ASA-00.html

  About routing, all traffic will go out of the ASA using intellectual property where the card encryption is applied, routing on linkysys devices just take care that this IP is routed Internet and that there is connection between the 2 ASAs.

  It may be useful

• Site to Site VPN tunnel is not come between 2 routers

  Dear all,

  I have 2 routers for branch which is configured for VPN site-to-site, but the tunnel does not come!

  I ran debug and I enclose herwith output for your kind review and recommendation. I also enclose here the 2 routers configs branch.

  Any idea on why the Site to site VPN is not coming?

  Kind regards

  Haitham

  You guessed it!

  Just because you have re-used the same card encryption for LAN to LAN and vpn-client traffic.

  This from the DOC CD

  No.-xauth

  (Optional) Use this keyword if the router to router IP Security (IPSec) is on the same card encryption as a virtual private network (VPN) - client - to-Cisco-IOS IPSec. This keyword prevents the router causing the peer for the information of extended authentication (Xauth) (username and password).
