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).

IPSec tunnel do not come between two ASA - 5540 s.

I've included the appropriate configuration of the two ASA lines - 5540 s that I'm trying to set up a tunnel of 2 lan lan between. The first few lines show the messages that are generated when I try to ping another host on each side.

Did I miss something that will prevent the tunnel to come?

SBS 2008 office1 Serv2008 Office 2 need to share assets between them via a site to site VPN tunnel

Hi all.

I really need help on this one.

The office 1 installer running SBS2008 Office 2 running Server 2008.

Each firm has its own FQDN Office 1 CompanyABC 2 A_B_C of the company office.

Each firm has its own internal IP address pool Office 1 192.168.69.xxx and office 192.168.20.xxx 2.

Site to site VPN tunnel between 2 office routers Netgear SRX5308 1 and 2 Netgear FVS318G Office established and working.

Each firm has its own DNS server and acts as a domain controller

How to configure the 2 networks to see each other and be able to use assets on every network (files, printers)?

Is it so simple that the addition of another pool internal IP for each DNS server?

Thanks in advance for your help.

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.

Using the same set processing on several site to site VPN tunnels

Hi all. I have a rather strange situation about site-to-site VPN tunnel.

On the one hand, I have a PIX 501 and on the other end an ASA5505 and a tunnel set up between them.

The problem is that on the side of the PIX, I can't establish a tunnel, but when the traffic starts on the side of the ASA the tunnel established as usual.

I checked the configurations on both ends and keys, passwords, mirror that LCD seems OK. The only thing that comes to my attention, it's that I have the same set of transformation used for 2 different tunnel on the side of PIX.

Can I use the same set of transformation on several tunnels or should I set a different transformation for each tunnel? Could be the source of the problem?

Use it on PIX

card crypto set pfs group2

Or on ASA, use:

card crypto set pfs Group1

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...

Thank you

GRE tunnels will not come on VPN IPsec/GRE

Hi all

We have 400 + remote sites that connect to our central location (and a backup site) using Cisco routers with vpn IPSec/GRE tunnels. We use a basic model for the creation of tunnels, so there is very little chance of a bad configuration on each router. Remote sites use Cisco 831 s, central sites use Cisco 2821 s. There is a site where the tunnels WILL refuse just to come.

Routers are able to ping their public IP addresses, so it is not a routing problem, but gre endpoints cannot ping. There is no NATing involved, two routers directly accessing the Internet. The assorded display orders seem to indicate that the SAs are properly built, but newspapers, it seems that last part just don't is finished, and the GRE tunnels come not only upward.

The attached log file, it seems that both its IPSEC & ISAKMP are created @ 00:25:14, then QM_PHASE2 end @ 00:25:15.

I don't have the remote router log file, and is very long, so I joined her. Before that I captured the log file, I enabled debugging ipsec & isakmp and immediately authorized the SAs.

Site to site VPN upward but not pass traffic (ASA 5505 8.3.1 and 9.2.3 version)

Hello

I'll put up a tunnel vpn site-to-site between two locations. Both have cisco ASA 5505 running a different version, I'll explain in more detail below. so far, I was able to get the tunnel to come but I can't seem to pass traffic, I work at this for days now and have not been able to understand why he will not pass traffic. Needless to say that the customer's PO would be on the fact that their VPN is not upward and they had to do by hand. I'll put the configs below, if possible can someone help me as soon as POSSIBLE, I really want to get this site up and running so that we do not lose the customer.

An IP address of 0.0.0.0 = site
Site B IP = 1.1.1.1

A Version of the site = 8.3.1
Version of the site B = 9.2.3

disconnecting from site-to-site vpn tunnel

Dear Cisco

I use the Cisco ASA 5505 5 builed VPN site to site.

B, C, D, E of the site all site-to-site VPN A with only IPSEC IKEv2 configurartion site.

Reading the Site an ASDM. Monitoring VPN can always read all four sites are connected. But I found that Site D and E during connection reset periodically with a few hours.

(1) I would like to know the connection during the reset time is normal or not?

(2) any installation or configuration can refine the site to site VPN. Make VPN tunnel more stable?

(3) any menthod can monitor VPN site-to-site is health or not?

Thank you very much for your help

Alan.

A. in general, the time is set to 86400 for expiration. It can also be defined by the amount of traffic

(B) Yes. Try turning on KeepAlive IKE

C. check the logs is as far as I know of

This is a good doc on VPN

http://www.Cisco.com/en/us/products/ps6120/products_tech_note09186a00807e0aca.shtml

Site-to-Site VPN Ping does not

I configured a vpn site-to site between two firewalls ASA 5505. Establishes the tunnel, but the icmp traffic does not pass. In fact, ping worked twice, but only at random. I need to work on a regular basis. I have attached the configurations as well as an output of the packet - trace both of the ASA and the IPSec and its ISAKMP. Thanks for any help you can provide.

Hi Mike,.

I see the following in your configuration:

map mymap 10-isakmp ipsec crypto dynamic dynmap

Sequence number of Th for the peer 2.2.2.2 is 20 so we first hit the dynamic map that could cause this problem.

To avoid this, I suggest you do the following:

No map mymap 10-isakmp ipsec crypto dynamic dynmap

map mymap 65535-isakmp ipsec crypto dynamic dynmap

To validate this fact, if you look at the SA on ASA1 ipsec, you will find that it was negotiated with dymap (card crypto seq 10) and not 20!

Site to Site VPN configuration does not

Hello

I just tried to set up a test site to site VPN. Diagram of arrangement is attached. Router R2 is supposed to act as the 'Internet' to allow connectivity between the two networks.

My VPN on ASA1 and ASA2 configs are below:

ASA1

Note to outside_cryptomap_1 to access list VPN traffic to encrypt

I can ping with the ASA2 ASA1, but when I try to test the VPN trying from one PC to another, I get nothing.

I tried a few commands show and they came out absolutely empty... as I have not configured:

SH in detail its crypto isakmp

There are no SAs IKEv1

There are no SAs IKEv2

SH crypto ipsec his

There is no ipsec security associations

Anyone have any ideas?

Hi martin,

Your configs are quite right. I tried your script, its works really well. Here's the configs & outputs.

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

Adam

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.
```

```
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.

ASA 5505 and ASA 5510 Site to Site VPN Tunnel cannot be established

Hi all experts

We are now plan to form an IPSec VPN tunnel from site to site between ASA 5505 (ASA Version 8.4) and ASA 5510 (ASA Version 8.0) but failed, would you please show me how to establish? A reference guide?

I got error syslog 713902 and 713903, how to fix?

I got the following, when I type "sh crypto isakmp his."

Type: user role: initiator

Generate a new key: no State: MM_WAIT_MSG2

Hugo

Hello

This State is reached when the policies of the phase 1 do not correspond to the two ends.

Please confirm that you have the same settings of phase 1 on both sides with the following commands:

See the isakmp crypto race

See the race ikev1 crypto

Also make sure that port UDP 500 and 4500 are open for communication between your device and the remote peer.

Finally, make sure you have a route suitable for the remote VPN endpoint device.

Hope that helps.

Kind regards

Dinesh Moudgil

Site to Site VPN tunnel between two ASA

I use the Site Wizard to Site on an ASA 5520, and ASA 5505 of the ADSM. Both are using 8.4 (5). When you create configurations. You follow the wizard configurations with manual what ACL s to allow the traffic of every subnet connected to talk to each other? Or they are automatically generated in the configuration file? Have not been to school yet to understand how to create the CLI VPN tunnels and what to look for.

Thank you

Carlos

Hello

First, I would like to say that I don't personally use ASDM for the configuration.

But you should be able to configure all the necessary elements for a connection VPN L2L base through the wizard.

I guess that typical problems to do so could relate to the lack of configuration NAT exempt or might not choose the setting "Bypass Interface Access List" that would mean you would allow traffic from the remote site in the 'external' ACL of ASA local interface. Like all other traffic coming from behind the 'outer' interface

If you share format CLI configurations and say what networks must be able to connect via VPN L2L then I could give the required CLI format configurations.

Site to site VPN tunnel - cannot ping the second interface of the firewall peer inside2

I have two ASA 5505 firewall each with a basic license: FWa and FWb. currently there is a VPN tunnel between them work. I added a second (inside2) interface to the firewall, FWb, but I can't ping firewall FWa, so that I can ping the inside interface of FWa.

I can ping the FWb inside interface 192.168.20.1 from the FWa inside 172.16.1.1 interface, but I can not ping to the 10.52.100.10 of the FWa FWb inside2 interface. I can not ping the gateway host FWa 10.52.100.1.

I show the essential configuration of two firewalls as well as the debug icmp output on the two firewalls that I ping the internal interfaces and of FWa FWb inside2.

Thank you

Hi odelaporte2,

Is very probably the "access management" command is not applied in the second inside, only inside primary (see the race management) which will confirm.

This command can be applied to an interface at a time, for example, if the law is now applied to the inside, it can not be applied to the inside2 at the same time.

It may be useful
