tunnel VPN ZFW problem

Recently I tried to build a tunnel VPN of LAN LAN 2 connecting an Asa to a current zone based firewall 2911. It's a standard IPSec psk tunnel nothing complicated. I got the tunnel to establish, but I could only get traffic to encap on the side of the SAA and decap on the side of 2911. I couldn't return circulation. I followed this doc classic here for IPSec in the last example.

http://www.Cisco.com/en/us/prod/collateral/vpndevc/ps5708/ps5710/ps1018/...

And I don't know that the SAA is right I have built a ton of those but I am new to zfw. I don't see anything about a NAT rule exempt. But as all used real IPs instead of NAT I wasn't sure and I have found no info. I do free NAT? If If you are using a roadmap on the end you NAT overload line config as in the past?

I also have a pair of area to "self" and I didn't know if I need something there to be able to do a ping from inside the 2911 interface when the tunnel is at the top of the remote end. Thank you

Is the pair area yourself, outside of itself?

And you say that you do not use only NAT, have real addresses (public routable addresses?), so why you have to make an exception for NAT you have not?

With tunnel VPN ASA5505 problem

The business needs is for a VLAN again on site to go directly back to an internet service to site B.

Site A and B are connected by a service of WES MB 100.

A site is a site of campus with about 25 switches. Him become VLAN on the site is for the engineer access only, so they can access their companys remote access service. This VLAN must stay back so there is very little potential of a trade-off on the live network.

The solution that I just put in place is to place an ASA5505 as the dhcp server for him VLAN become to Site A. All clients on that VLAN become get a 192.168.100.x address. The external interface on the ASA5505 to Site A is put on the live network to allow a site VPN tunnel to be put in place between the ASA5505 and the Internet - an another ASA5505 firewall

The Site A ASA5505 was put in place with inside and outside interfaces with the same level of security. 192.168.100.x subnet is exempt from NAT. Traffic is configured to transmit via the interfaces with the same level of security and the tunnel of L2L is coming.

But I can not all connectivity to the internet from any host on the 192.168.100.x VLAN.

This is made more complex because the external interfaces on both of the ASA are the corporate network...

The default route to the Site B ASA5505 is 87.xx.xx.1, the ISP router.

The Site B ASA5505 connects directly to the ISP router.

Can you help me to know where I have gone wrong?

Dan

There are some parts of the configuration that you have published to that surprise me, such as the assignment of the default route on the inside interface. But these things are not at the heart of your problem. I agree that the core of your problem is probably the sheep access list. If I understand your needs, what you need is 192.168.100.0 is not translated by going to meets B, and is translated by going to the Internet. But your translation says access list never 192.168.100.0 since your access list as another destination:

access-list no. - nat extended ip 192.168.100.0 allow 255.255.255.0 any

My suggestion is to rewrite this access list and change the destination of the 'all' to be addresses behind B (LAN to B).

Tunnel VPN BEFVP41-BEFVP41 after a certain time blocks

I have 2 networks in different countries with routers BEFVP41 put in place to establish a VPN tunnel. Setup in country A has a static Internet IP address, in country B a dynamic IP address. For the remote security gateway a DynDNS-FULL domain name is inserted. (I tried "Any", but for some reason any that does not work.) However this is not a problem at this point). Installation works perfectly in the sense that a VPN connection is established and works as it should.

However the annoying problem is that after some time, usually during the night, the VPN tunnel seems to block even if it remainsl upward. I can not all data through more. I can get running again by resetting the modem and router b (I couldn't try if that would also be the case if the modem and the router could be reinitialized, because these are unmanned at the moment)

In the situation of blocking internet connection is OK on both sides. A connection between the networks outside the VPN tunnel works without problem. The VPN can be disconnected and reconnected, but he remains blocked.

Both routers are the latest firmware 1.02.06, build 003.

Thanks in advance for any help to solve this annoying problem.

You have to try to adjust the MTU, change it to 1350...

Tunnel VPN remote Internet and VPN remote VPN from Site to Site traffic?

Hello

We try to remote traffic from our users VPN tunnel through our ASA 5510 as well as to allow the only access for remote user VPN traffic to the other end of the all our VPN site-to-site connected to the same ASA. Basically, we who want to VPN in the network in order to access all of our networks business. We try to get away with this without using split Tunneling.

I can currently get internal traffic from the remote user VPN to reach all other vpn site-to-site tunnels without the internet in tunnel. The problem is when I add the following statement to the NAT:

NAT (outside) 1 10.10.19.0 255.255.255.0 * 10.10.19.0 is the address of the remote VPN Client

Internet traffic to the remote VPN starts to get in the tunnel, but I lose the opportunity to reach one of the other tunnels from site to site by the remote VPN tunnel.

I also begin to receive the following errors in the journal of the ASA

3 July 1, 2009 12:34:18 305005 10.10.19.255 137 no group of translation not found for udp src outside:10.10.19.3/137 dst outside:10.10.19.255/137

Any help with how NAT statements must be defined for this work would be appreciated.

Thank you

Tunnel VPN from Site to Site dynamic

I spent the last 2 days, try to set up a dynamic tunnel VPN site to site of a Cisco 5510 to a Cisco SA540. The 540 is a dynamic supplier that can not be changed. There a dyndns account.

I was lucky that the other 10 sites are all static and the ADSM Assistant creates these tunnels without problems.

What I try to do is:

Is it possible to do it VIA ADSM?

If this isn't the case, someone please in detail can help with orders.

Kind regards

PP

Hello Paul,

This is possible thanks to the ASDM, but you do have to use some advanced settings:

Configuration > VPN Site to Site > advanced > Tunnel groups

It change the group called "DefaultL2LGroup" and add the brightness button before the SA540 (Note: all of your sites with dynamic IP addresses will have the same key communicated in advance, if you have IPSec VPN clients, it will be a good idea to use a different key).

Click ok and then apply.

Then go to Configuration > VPN Site to Site > advanced > Crypto Maps and add a new entry dynamic

Make sure that you match the phase 2 are on your SA540 (pictured ESP-AES-128-SHA), select a dynamic strategy and make the last sequence number (65535) then ok, apply.

Then go to Configuration > VPN Site to Site > advanced > IKE policies and make sure you have corresponding policies of the phase 1.

If no corresponding policy is found, add them.

Through CLI:

IKEv1 crypto policy 1

preshared authentication

aes encryption

sha hash

Crypto-map dynamic outside_dyn_map 65535 set transform-set ESP-AES-128-SHA ikev1

ASA 5505 VPN Ping problems

Hi all

First of all, I apologize if this is something that I can google. My knowledge of the administration of the network is all self-taught, so if there is a guide that I missed please point me in the right direction, it is often difficult to Google the terms for troubleshooting when your jargon is not the height.

The main problem is that when ping devices internal when you are connected to the results are very inconsistent.

Ping 192.168.15.102 with 32 bytes of data:

Reply from 192.168.15.102: bytes = 32 time = 112ms TTL = 128

Request timed out.

Request timed out.

Request timed out.

We have implemented an IPSec VPN connection to a remote Cisco ASA 5505. There is no connection problems, connection seems constant, etc. good packages. At this stage, I can only assume I have configuration problems, but I was watching this while if long and pair with my inexperience configuration of these settings I have no idea where to start. My first impressions are that LAN devices I'm ping do not send their response back or the ASA does not know how to route packets back?

Here is a dump of the configuration:

Output of the command: "show config".

Hi Graham,

My first question is do you have a site to site VPN and VPN remote access client.

After checking your configuration, I see you don't have any Site to SIte VPN configuration, so I'm assuming you ara facing issue with the VPN client.

And if I understand you are able to connect VPN client, but you not able to access internal resources properly.

I recommend tey and make the following changes.

First remove the following configuration:

NAT (inside) 0 inside_nat0_outbound_1 list of outdoor access

NAT (inside) 1 192.168.15.192 255.255.255.192

You don't need the 1st one and I do not understand the reason for the second

Second, one is your pool IP subnet (192.168.15.200 - 192.168.15.250) and I don't know why you added this NAT.

If possible change your subnet pool all together because we do not recommend to use th ip POOL that is similar to your local network.

Try the changes described above and let me know in case if you have any problem.

Thank you

Jeet Kumar

VPN-ASA5505 problem

Hi all

I inherited this VPN and get slowly upward. At least users can connect to it now! I had a few problems. Users can connect to the VPN, but cannot ping or access shared files on the server (192.168.2.3), but the VPN users must be able to make full use of the network.

I removed the NAT rule.

#no nat (inside) 1 0.0.0.0 0.0.0.0)

And after removing that, VPN users have been able to navigate and access to internal resources. However, users in the office now had no internet. I went and added the rule of return and returned internet.

Believe it is related to the split tunneling, what can I do to activate full VPN access and still have internet at Headquarters?

Hello

Please add the following to your configuration:

nonat_inside ip access list allow any 192.168.2.0 255.255.255.0

NAT (inside) 0-list of access nonat_inside

You must keep the "nat (inside) 1 0.0.0.0 0.0.0.0 ' so that your users access to the Internet.

"Nat (inside) 0 nonat_inside access-list" allows to bypass the above rule only for traffic destined to the VPN pool.

In addition, it is to you if you want to use split tunneling or not.

More information on tunneling split:

ASA/PIX: Allow the tunneling split for the VPN Clients on the example of Configuration of ASA

Tunnel VPN and NAT

Hello. I'm creating a tunnel VPN IPSec LAN - to - LAN of my ASA5510 to another network but met an obstacle bit. My counterpart on the other side has informed me that he already has a VPN tunnel to another company that has the same IP range as my network(10.100.16.0 /24) and can not create the tunnel.

I was wondering is it possible to use NAT on the VPN tunnel so that traffic that goes from my network over the VPN tunnel gets translated and my counterpart on the other side sees this reflects the range of IP addresses?

Thanks in advance for any help.

Hello

Yes, you can use the same address you already use for internet access.

Just update your list of access crypto to reflect the new address and to ensure that the third party did the same.

Tunnel VPN site to Site with 2 routers Cisco 1921

Hi all

So OK, I'm stumped. I create much s2s vpn tunnels before, but this one I just can't go there. It's just a tunnel VPN Site to Site simple using pre-shared keys. I would appreciate it if someone could take a look at our configs for both routers running and provide a comment. This is the configuration for both routers running. Thank you!

When the GRE tunnel carries your traffic to private ip range, your ACL must contain address of the host of point to point the IPSec tunnel.

Since then, both routers are running EIGRP in the corporate network, let the EIGRP Exchange routes via GRE tunnel, which is a good practice, rather than push the ip ranges private individual through the IPSec tunnel.

Let me know, if that's what you want.

Tunnel VPN RV-042 for Dual WAN Failover backup function

We have customers with dual WAN failover scenarios with site-to-site VPN tunnels.

In the past, the VPN tunnel backup feature has been available in the RV-082.

One of the new RV-042 firmware versions have the function of backup Tunnel VPN available?

The feature is supported on the RV042 V3 hardware.

Bring up the tunnel vpn crypto without interesting traffic map

Is it possible on ASA to bring up the tunnel vpn site to site static crypto map without generating interesting traffic? I want to reverse route injection generate road dynamic until traffic begins to flow.

Roman,

Unless something chnaged recently RRI inserts routes without present SAs, meaning that they are static (in contrast to current default behavior on IOS 12.4 (9) T-I_think leave).

But to answer the question, in more recent versions, you can bring up the tunnel using packet - trace CLI.

M.

Edit: request for improvement that will present the same features of IPP on ASA as on IOS:

Tunnel VPN site to Site - aggressive Mode

I searched the community for answers to this and that you have not found quite what I was looking for (or what seems logical). I have an ASA 5510 to A site with one website VPN tunnel to a SonicWall to site B. Which works very well. I need to create a tunnel for site C to site a using a tunnel of aggressive mode. I'm not quite sure how to do this. Any suggestion would be great!

NOTE: I have included the parts of the running configuration that seem relevant to me. If I missed something please let me know.

Impossible to access them Internert through the split tunneling VPN client.

I divided tunnel configured on a PIX 515. The remote VPN client connects to the PIX very well and can ping hosts on the internal network, but cannot access the Internet. Am I missing something? My config as shown below.

In addition, I don't see the routes on the VPN client via statistics (screenshot below)

All opinions are appreciated.
