Site to Site VPN IPsec IPv6 on issue of routers-Tunnel
Hi, I am experiencing a problem can any one address the question below and let me know the solution. I have two routers and try to build "Site to Site VPN IPsec IPv6". I followed orders from Cisco and community document but when I apply my profile of ipsec for tunnel interfaces, that the tunnel is down.

Ali,
VTI tunnels are meant to be broken when there is no active negotiated spinnakers.
The tunnel will go towards up/face upwards when there is a means of transport of packages - i.e. the SPIs are present.
You can control the order spinnakers 'show peer's crypto ipsec '.
For debugging:

Site-to-Site VPN IPSEC falls intermittently
Site-to-Site VPN IPSEC falls intermittently
I am currently having a problem with a VPN from Site to Site traffic not only not intermittently. When the problem occurs, I can't Ping the remote site to the AC Site. But I can solve the problem by Pinging from HQ at the Remote Site. My network is currently configured as follows
-------HQ------
7.0 (4) version of pix 515 with card Ethernet 4 ports.
Outside of the interface connected to the Broadband DSL link.
Outside2 Interface connected to the second link DSL broadband
-Distance-
I have 4 Remote Sites. 2 sites connect you to each connection to wide band at HQ to spread the load to HQ
6.3 (5) pix 501 version
# The problem #.
All VPN establishes successfully to the HQ Pix
Intermittently, a remote site will report that they cannot connect to servers/services in the HQ. When I do a show crypto ipsec's and see the crypto isakmp his headquarters there is no entry for the remote site. However when I do the same on the remote site there is an entry for the HQ. With debugging on the remote site pix I try to ping from a pc to the HQ server and I get the following (see below). If I do a "ipsec Isakmp security association claire crypto ' and ' clear crypto ipsec his ' on the pix of remote site, then I can successfully ping all servers in headquarters.
This problem seems to have taken place only when I upgraded the pix of a 501 to 515 and added another 2 remote sites and a second broadband, as described above. I'm afraid that there is a problem with software version 7 Pix. Any advice would be greatly appreciated.

Cisco ASA Site to Site VPN IPSEC and NAT question
Hi people,
I have a question about the two Site to Site VPN IPSEC and NAT. basically what I want to achieve is to do the following:
ASA2 is at HQ and ASA1 is a remote site. I have no problem setting a static static is a Site to IPSEC VPN between sites. Guests residing in 10.1.0.0/16 are able to communicate with hosts in 192.168.1.0/24, but what I want is to configure the NAT with IPSEC VPN for this host to 10.1.0.0/16 will communicate with hosts in 192.168.1.0/24 with translated addresses
Just an example:
N2 host (10.1.0.1/16) contacted N1 192.168.1.5 with destination host say 10.23.1.5 No 192.168.1.5 (notice the last byte is the same in the present case,.5)
The translation still for the rest of the communication (host pings ip destination host 10.23.1.6 N3 N2 not 192.168.1.6 new last byte is the same)
It sounds a bit confusing to me, but I've seen this type of configuration before when I worked for the supplier of managed services where we have given our customers (Ipsec Site to Site VPN with NAT, don't know how it was setup)
Basically we contact the customer via site-to-site VPN hosts but their real address were hidden and we used as translated address more high 10.23.1.0/24 instead of (real) 192.168.1.0/24, last byte must be the same.
Grateful if someone can shed some light on this subject.
Hello
OK so went with the old format of NAT configuration
It seems to me that you could do the following:
- Configure the ASA1 with static NAT strategy
- access-list L2LVPN-POLICYNAT allowed ip 192.168.1.0 255.255.255.0 10.1.0.0 255.255.0.0
- public static 10.23.1.0 (inside, outside) access-list L2LVPN-POLICYNAT
- Because the above is a static NAT of the policy, this means that the translation will be made only when the destination network is 10.1.0.0/16
- If you have for example a PAT basic configuration to inside-> external traffic, the above NAT configuration and the custom of the actual configuration of PAT interfere with eachother
- ASA2 side, you can normally configure NAT0 / NAT Exemption for the 10.1.0.0/16 network
- Note of the INTERIOR-SHEEP access-list SHEEP L2LVPN
- the permitted INSIDE SHEEP 10.1.0.0 ip access list 255.255.0.0 10.23.1.0 255.255.255.0
- NAT (inside) 0-list of access to the INTERIOR-SHEEP
- You will need to consider that your access-list defining the VPN encrypted L2L traffic must reflect the new NAT network
- ASA1: allowed to access-list L2LVPN-ENCRYPTIONDOMAIN ip 10.23.1.0 255.255.255.0 10.1.0.0 255.255.0.0
- ASA2: list L2LVPN-ENCRYPTIONDOMAIN allowed ip 10.1.0.0 access 255.255.0.0 10.23.1.0 255.255.255.0
I could test this configuration to work tomorrow but I would like to know if it works.

ASA ASA from Site to Site VPN IPSec Tunnel
Any help would be greatly appreciated...
I have two devices Cisco ASA with a Site for the configuration of the tunnel VPN IPSec Site as follows: -.
Site #1 - Cisco ASA running version 8.2 (1) with an internal range of 10.0.0.x/24
Site #2 - Cisco ASA running version 8.2 (1) with an internal range of 10.1.1.x/24
Site #1 is simple and has a dynamic NAT rule which translates all of the inside and the outside (public IP) of the SAA.
Internet access works very well in all workstations of this site. A static route is configured to redirect all traffic to a public router upstream.
Site #2 is slightly more complicated; the Cisco ASA is configured with 10.1.1.254/24 as its interior IP address and 10.1.2.254/24 as its external IP address. A dynamic NAT rule is configured to translate everything inside as the 10.1.2.254 (outside) address of the ASA. A default static route is then configured to redirect all traffic to a Draytek device on 10.1.2.253. This device then performs its own private Public NAT. Again the Internet works fine all hosts inside the Cisco ASA (10.1.1.x)
The IPSec tunnel is created with the networks local and remote endpoint as above (10.0.0.x/24) and (10.1.1.x/24). The Draytek at the Site #2 device is configured with a form of DMZ that allows essentially ALL traffic toward the front directly on the external interface of the ASA (10.1.2.254). The Phase 1 and Phase 2 negotiation of the tunnel ends correctly, and the tunnel is formed without any problem. However, all traffic passing on networks ICMP does not end and the Syslog reports the following-
Site #1-

The ACL is configured to allow segments of LAN out to any destination. At this point, I left scratching my head, as my original theory was to blame the Draytek, but after reading the documentation given to the DMZ host configuration, it appears this parameter is configured all traffic is simply forwarded to the IP address (in this case, the Cisco ASA interface outside).
Anyone can shed light on a possible cause of this problem?
Thank you
Nick
did you bypass the vpn traffic between 10.0.0 and 10.1.1 to be NAT - ed on the two ASA?
Please provide the following information
-set up the tunnel
-show the isa cry his
-show the ipsec cry his
-ping of the site 1 site 2 via tunnel
-capture "crypto ipsec to show his" once again
-ping from site 2 to 1 by the tunnel of the site
-capture "crypto ipsec to show his" once again
-two ASA configuration.

backup of MTU 1500
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.

Design site to Site VPN w/NAT traversal issue
Hi, I have a number of site to site VPN that end on a PIX. I intend to migrate these VPN to a router that sits on a demilitarized zone connected to the PIX. Before doing that I'm going to set up a private network new virtual to end on the router but I also need than VPNS that end on the PIX to be not affected.
If I configure NAT traversal on the PIX, affected my other VPN?
Thanks in advance
DOM
Hi Dom,
Why do you want to configure NAT-Traversal on PIX, if you wish to terminate your VPN router (which is on the DMZ).
Do you do any NAT on PIX thru the router?
If you want to configure NAT-Traversal, it must be configured on the end (on the router in your case) devices.
Example:
When a user with Cisco client or Cisco router behind NAT wants to connect to another device (such as PIX, ASA, or router) NAT - T must be configured on the machine (which will be the PIX or ASA)
Hope that helps.

Site to site VPN - need help to set up several tunnels
I currently have tunnels VPN site-to-site of two remote sites with 1720s to connect to an ASA5510 on my site TOWN_HALL. (see attached diagram)
It works well, but I want to add connectivity between the 1720-A LAN (172.20.3.0/24) and LAN 1720 - B (172.22.3.0/24). What is the best way to do it? The years 1720 can be configured with direct VPN L2L tunnels or that will affect the existing tunnels is the ASA5510? If so, I'm guessing that each 1720 will have to go through the ASA first.
Thank you.

Please enter the following command

on pix not sure of the syntax, I think it is

What we are trying to do here is basically allowing vpn opening ports
Alternatively you can open udp 500 and esp (or port ip 50) out to in on the two firewalls

Hi all,
Could someone tell me please if on the IPSec VPN (not GRE over IPSec) site to supported routing protocols?
Thank you.
Hello
Well, a Site does not support multicast traffic.
http://www.ietf.org/RFC/rfc2401.txt
4.1 Definition and Scope A Security Association (SA) is a simplex "connection" that affords security services to the traffic carried by it. Security services are afforded to an SA by the use of AH, or ESP, but not both. If both AH and ESP protection is applied to a traffic stream, then two (or more) SAs are created to afford protection to the traffic stream. To secure typical, bi-directional communication between two hosts, or between two security gateways, two Security Associations (one in each direction) are required. A security association is uniquely identified by a triple consisting of a Security Parameter Index (SPI), an IP Destination Address, and a security protocol (AH or ESP) identifier. In principle, the Destination Address may be a unicast address, an IP broadcast address, or a multicast group address. However, IPsec SA management mechanisms currently are defined only for unicast SAs.
The only possible mechanism is to use the GRE over IPSec.
I hope this helps.
Kind regards

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!

Unfamiliar with the VTI, but I think you are missing:
ipv4 ipsec tunnel mode
Profile of tunnel ipsec protection
Also don't think that you need crypto card in the tunnel because it is already on fa0/0. What looks like the access-list 101? Take a look at this doc:

Site to Site VPN - cannot ping remote subnet
Hi all.
I have a site to site VPN IPSEC between a 5510 (HQ) and 5505 (Remote). Everything works on the tunnel. Crypto cards and ACL is symmetrical. I see that the tunnel is in place for the required subnets. However, I can not ping of internal subnets inside 5510 to Remote LAN inside 5505 and vice versa. I have other rays VPN 5510 where I can ping within remote LAN successfully x.x.x.x. Can figure out what I'm missing. I can ping internet points, but cannot ping HQ.
Any suggestions?
I'm also an instant learn the ASAs, so I'm not an expert. I know that I encouraged outside ICMP. My statement SHEEP and crypto are running off of the same group of objects that lists subnets of HQ.
Thanks in advance.
5505 lack the command:
management-access inside

Connectivity between two site to site VPN
I have two remote sites that each connect to our main office using a site to site VPN. Remote offices have 831 routers. The main office has a PIX 515.
A remote office is 192.168.15.X and the other is 192.168.100.X. The main office is on a 10.X.X.X network.
Each remote office can contact the office with no problems. However, they cannot communicate with each other at all and I need this to work. I just want to be able to access the network 192.168.100.X network 192.168.15.X through the VPN tunnel that is already set up between each remote desktop.
I tried to add the other network to the ACL for the tunnel, but that did not work. I feel I'm missing something simple.
For example, the following ACL initially.
Note access-list 103 IPSec rule
access-list 103 allow ip 192.168.15.0 0.0.0.255 10.0.0.0 0.255.255.255
I added this line to this LIST.
access-list 103 allow ip 192.168.15.0 0.0.0.255 192.168.100.0 0.0.0.255
But that did not help.
Thanks in advance.
Hello
What code are you running on the Pix. Talk to talk IPSEC connectivity is supported only in version 7.0 and higher.
Enhanced support has spoke-to-Spoke VPN
Version 7.0 (1) improving support communications a spoke-to-spoke (customer-to-customer) VPN, providing the ability to traffic to enter and exit the same interface. In addition, remote access to splitting tunnel connections can be completed on the external interface of the security apparatus, enabling traffic destined to the Internet for remote user VPN tunnels to leave on the same interface as it happened (after that the firewall rules have been applied).
The same-security-traffic command permits traffic to enter and exit the same interface when it is used with the keyword a spoke-to-spoke VPN using intra-interface. For more information, see the section "Allows Intra-Interface traffic" in the in the command line Configuration Guide Cisco Security Appliance.

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.
Federico.

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:

Hope this info helps!
Note If you help!
