Adding networks to the tunnel VPN ACL

Hello. On a remote location, I have to add additional networks access to our networks to the central location and I was wondering is it as simple as the addition of these networks to ACL on both sides of the tunnel to allow access or is there something more to do? I just want to be sure because it is so simple.

VPN is the site to site.

Thanks in advance for any help.

Add traffic to your acl crypto of interesting traffic and your nat exemption acl.

How to allow access to a local area network behind the cisco vpn client

Hi, my question is about how to allow access to a local area network behind the cisco vpn client

With the help of:
- Cisco 5500 Series Adaptive Security Appliance (ASA) that is running version 8.2 software
- Cisco VPN Client version 5.0 software
Cisco VPN client allows to inject a local routes in the routing table Cisco ASA?

Thank you.

Hi Vladimir,.

Unfortunately this is not a supported feature if you connect through the VPN Client. With VPN Client, that the VPN Client can access the VPN Client LAN host/local machine, not host from the local network to business as customer VPN is not designed for access from the local company network, but to the local corporate network.

If you want to access from your local business to your LAN network, you need to configure LAN-to-LAN tunnel.

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:

Default route inside the tunnel VPN Site to site

We want to carry the default traffic within the site to site VPN tunnel, our goal is to route all traffic including default branch road and HO HO help branch for surfing the internet.

I have due to difficulties

1. cannot configure dynamic NAT for the router in the branch on the ASA HO, I know configuration for 8.2, but know not about 8.4

This is the configuration for the 8.2, if someone can translate to 8.4, which would be a great help

NAT (outside) 1 192.168.230.0

2. I do not know how to write the default route on the branch office router to send all traffic within the VPN tunnel

Hello

As I understand it then you want to route ALL traffic from the Remote Site to the Central Site and manage Internet traffic there.

I suppose you could define "interesting traffic" in configuring VPN L2L ACL / access-list in the following way

Branch router

extended IP access list

allow an ip

ASA central

ip access list allow one

The idea behind the type of ACL for the VPN L2L above configurations is that, for example, the branch office router has a rule that sets connection coming from the local LAN for 'any' destination address must be sent to the VPN L2L connection. So, it would be in such a way that all the traffic will be sent to the Central Site via VPN L2L.

I must say however, that the VPN router configurations side are not more familiar to me because I manage especially with ASA Firewall (and to some extent still PIX and FWSMs)

I guess that on the ASA Central you will PAT translation to "outside" so that the host can access the Internet?

You would probably do something like this

object-group network to REMOTE-SITE-PAT-SOURCE

network-object

interface of REMOTE-SITE-PAT-SOURCE dynamic NAT (outside, outside) after auto source

If you don't want to use the 'outside' IP address, then you will have to create a 'network of object' for address IP of PAT and use it in the line of NAT configuration above instead of "interface".

Alternate configuration might be

network of the REMOTE-SITE-PAT object

subnet

dynamic NAT interface (outdoors, outdoor)

You also need to enable

permit same-security-traffic intra-interface

To allow traffic to enter and exit the same interface on the ASA

All these answers are naturally suggestion on what you have to do. I don't know what kind of configurations you have right now.

Hope this helps in some way

Limit the bandwidth in the tunnel VPN on Cisco ASA

Hello

I have a site VPN tunnel to create with the local desktop client. I fear that the traffic in the tunnel in impacting the Internet bandwidth for the entire office. Is it possible to limit bandwidth on the speed VPN tunnel. I have attached a configuration that shows the configuration of the ASA at the local office.

Any help would be much appreciate. I watched QoS mapping but it's hard to make sense.

Thank you very much

Kind regards

Michael.

The ASA supported QoS features are:
Police, LLQ and Traffic Shaping

To avoid the individual flows hogging the bandwidth of the network, you can limit the maximum bandwidth used by flow (with the police)
The police is a way of ensuring that no traffic exceeds the rate (in bits per second) that you configure,
so make that person not traffic or the class can return to any of the resource.
When traffic is higher than the maximum rate, the ASA removes the excess traffic. Policy defines also the largest single burst of allowed traffic.

Example of font options:
class policing_map_name hostname(config-pmap) #.
Police hostname(config-pmap-c) # {exit | entry} to compliance rates [conform burst]
[action in line [drop | send]] [action exceed [drop | send]]

That is to say

HostName (config) # class - police-class card
HostName(config-CMAP) # match any
HostName(config-CMAP) # QoS_policy policy-map
class police_class hostname(config-pmap) #.
HostName(config-pmap-c) # exit police 56000 10500

The configuration depends on the "this" base that you want to limit the connection.

Command to check the tunnel VPN S2S awhile in the cisco router

Dear all,

Please share the command check S2S tunnel of time that is configured on the router.

There are commands that define the lifetimes of (his) IPSec Security Associations, ISAKMP.

For example:

crypto ISAKMP policy 1
BA 3des
preshared authentication
Group 2
life 3600

life 3599 seconds crypto ipsec security association

... and you can determine the remaining lifetime for these SAs with the following commands:

SH detail session crypto

SH in detail its crypto isakmp

SH crypto ipsec his

The delta between the lifetime (s) configured and remaining life will tell you how much time has passed since the last regeneration, but that is as close you are likely to have to determine when the tunnel came first.

You could use other means as States of syslog for you say when a Tunnel is a transitioning upwards or downwards.

Best regards

How to restrict the tunnel VPN Site to site traffic thrue

Hello

I have a tunnel from site to site, where Site 1 is the local site and main site. and 2 the site is the remote site.

How to limit the traffic of site 2, so that they can only reach a few IPS on the lokal site.

But since the lokal site all IP addresses must be able to reach all of the IP addresses to site 2 (remotely).

an access list to the 'inside' interface does not work, since all the acl is bypassed for the interfaces for IPSEC traffic.

Then, I tried to make a political group where I only allow traffic to servers specifik, but site 2 can still reach everything on the lokal site.

Am I missing here?

Best regards

Erik

Hi Erik,

Unfortunately, the only options that we have are VPN filters that are two-way and disabling the sysopt feature.

If you have a core switch/router we can block traffic on this device by using the access list or null routes.

See you soon,.

problem of traffic flow with tunnel created the network with a tunnel to a VPN concentrator

Hi, I worked with Cisco and the seller for 2 weeks on this.II am hoping that what we are witnessing will ring a Bell with someone.

Some basic information:

I work at a seller who needs from one site to the other tunnel. There are currently 1 site to another with the seller using a Juniper SSG, which works without incident in my system. I'm transitioning to routers Cisco 2811 and put in place a new tunnel with the seller for the 2800 uses a different public ip address in my address range. So my network has 2 tunnels with the provider that uses a Cisco VPN concentrator. The hosts behind the tunnel use 20x.x.x.x public IP addresses.

My Cisco router will create a tunnel, but I can't not to hosts on the network of the provider through the Cisco 2811, but I can't get through the tunnel of Juniper. The seller sees my packages and provider host meets them and sends them to the tunnel. They never reach the external interface on my Cisco router.

I'm from the external interface so that my endpoint and the peers are the same IP address. (note, I tried to do a static NAT and have an address of tunnel and my different host to the same result.) Cisco has confirmed that I do have 2 addresses different and this configuration was a success with the creation of another successful tunnels toa different network.)

I tested this configuration on a network of transit area before moving the router to the production network and my Cisco 2811 has managed to create the tunnel and ping the inside host. Once we moved the router at camp, we can no longer ping on the host behind the seller tunnel. The seller assured me that the tunnel setting is exactly the same, and he sees his host to send traffic to the tunnel. The seller seems well versed with the VPN concentrator and manages connections for many customers successfully.

The seller has a second VPN concentrator on a separate network and I can connect to this VPN concentrator with success of the Cisco 2811 who is having problems with the hub, which has also a tunnel with Gin.

Here is what we have done so far:

(1) confirm the config with the help of Cisco 2811. The tunnel is up. SH cyrpto ipa wristwatch tunnel upward.
(2) turn on Nat - T side of the tunnel VPN landscapers
(3) confirm that the traffic flows properly a tunnel on another network (which would indicate that the Cisco config is ok)
(4) successfully, tunnel and reach a different configuration hosting
(5) to confirm all the settings of tunnel with the seller
(6) the seller confirmed that his side host has no way and that it points to the default gateway
(7) to rebuild the tunnel from scratch
8) confirm with our ISP that no way divert traffic elsewhere. My gateway lSP sees my directly connected external address.
(9) confirm that the ACL matches with the seller
(10) I can't get the Juniper because he is in production and in constant use

Is there a known issue with the help of a VPN concentrator to connect to 2 tunnels on the same 28 network range?

Options or ideas are welcome. I had countless sessions with Cisco webex, but do not have access to the hub of the seller. I can forward suggestions.

Here's a code

Tunnel of Split VPN Setup ASA to force inside the tunnel for single address

Hi all

We have an ASA with IPSec VPN facility to addresses Internet of Tunnel from Split. We have an Internet address that must come from the external interface of the ASA. I have added this address to the list of split tunnel and confirmed on the client that is the road to the tunnel, but I'm not able to get to this address via the VPN.

How the ASA to allow this unique Internet address to come via the VPN and route back on the same interface to the Internet and the return traffic to back up in the client VPN tunnel.

I need to get to the address is 213.92.42.118. Here's the config relavent (let me know if I left anything):

Any help is appreciated.

Hi Jeff,

Just had a chance to look through the Setup and I guess that configured nat is incorrect.

access-list extended sheep allowed any ip VPN_Pool 255.255.255.0
NAT 0 access-list sheep (LUXCVGASA01i)
NAT (LUXCVGASA01i) 2 10.0.0.0 255.0.0.0

Global (LUXCVGASA01e) 2 1.1.1.1

The access-list says sheep that ALL traffic goes to the pool of the VPN to go UN-natted. So, when you try to access the public ip address via the tunnel VPN, the traffic the ASA, ASA then performs a search destination NAT and matches the nat command "nat (LUXCVGASA01i) 0 access-list sheep." If the ASA detects a destination NAT translation, it will bypass route search and uses the destination NAT translation to determine the output interface (in this scenario, the output interface is LUXCVGASA01i.

So, to resolve this problem, change the acl sheep from "any to VPN_Pool 255.255.255.0" inside"to the network VPN_Pool 255.255.255.0.

clear xlate and re-initialization of the tunnel, and this should solve the problem.

Let me know if that answers your query.

Kind regards

Hello guys,.

I have Cisco ASA5520 facing the ISP with private IP address. We don't have a router and how to get the IPSec VPN through the internet?

The question statement not the interface pointing to ISP isn't IP address private and inside as well.

Firewall configuration:

Firewall outside interface Gi0 10.0.1.2 > ISP 10.0.1.1 with security-level 0

Firewall inside the interface Ethernet0 192.168.1.1 > LAN switch 192.168.1.2 with security-level 100

I have public IP block 199.9.9.1/28

How can I use the public IP address to create the IPSec VPN tunnel between two sites across the internet?

can I assign a public IP address on the Gig1 inside the interface with the security level of 100 and how to apply inside to carry on this interface?

If I configure > firewall inside of the item in gi1 interface ip address 199.9.9.1/28 with security-level 100. How to make a safe lane VPN through this interface on the internet?

I'm used to the public IP address allocation to the interface outside of the firewall and private inside the interface IP address.

Please help with configuration examples and advise.

Thank you

Eric

Unfortunately, you can only complete the VPN connection on the interface the VPN connection source, in your case the external interface.

3 options:

(1) connect a router in front of the ASA and assign your public ip address to the ASA outside interface.

OR /.

(2) If your ISP can perform static translation of 1 to 1, then you can always finish the VPN on the external interface and ask your provider what is the static ip address assigned to your ASA out of the IP (10.0.1.2) - this will launch the VPN of bidirectionally

OR /.

(3) If your ISP performs PAT (dynamic NAT), then you can only start the tunnel VPN on the side of the ASA and the other end of the tunnel must be configured to allow VPN LAN-to-LAN dynamics.

S2S VPN - cannot get the tunnel upward

I couldn't lift a VPN site-to site because of a configuration error that I can't fix

The topology is Server1 > Hub > ASA - 1 ASA-2<><>

When I launch a ping server 1 Server 2 to try to get out of the tunnel to the top, I get the following error:

No matter which side I am ping, I get the error on both of the ASA. Here is the config for the two ASA, thanks for any help.

You won't have a road to 192.168.200.2 so he was not able to locate the next hop for the traffic of the tunnel.

These static routes adding causes all traffic to be sent to the default gateway of the internet, including VPN and VPN traffic not.
So adding a route for 192.168.200.0 pointing to 80.1.1.X gave the same results.

Hello

To be honest, I can't see anything in the configuration that should be a problem.

Your NAT settings seem to be correct.

You have the global setting of "sysopt connection permit - vpn" who does not appear in this form in the CLI configuration. This configuration means essentially that the SAA would allow traffic from a VPN connection to work around interface ACL of the interface when the VPN connection is completed (outside)

Your ACL Split Tunnel is also correct.

You might connect with VPN Client and run a continuous ICMP to a host of LAN and provide an output of the following command after a the ICMP has run a few seconds

Crypto ipsec to show his

Should see the counters of VPN.

You can also try adding

management-access inside

This should allowed you to the 'internal' to the ASA IP ICMP and also manage ASA through the VPN connection by using the 'internal' the IP address provided you have enabled it. But for this you need to change the configuration of "nat" in this

NAT (inside, outside) static source inside obj obj-indoor destination static obj - vpn vpn-obj-research route

Hope this helps

Connectivity to the remote VPN site adjacent networks

Star topology with Corporate office which acts as hub (192.168.1.x) and remote sites connected by relay frames, except for another network (172.16.x.x) in the building served by 3560 switch company.

On my remote site vpn (10.0.1.x) I can ping network 172.16.x.x, but not the 192.168.1.x network. What I'm trying to do is to allow the network traffic remote 10.0.1.x (which connects directly via the VPN network 172.16.x.x) to reach the network 192.168.1.x and vice versa.

I'm sure its a combination of NAT/routing issue I forget.

I'm new to PIX / ASA in general and it's the first vpn L2L I install. If someone can point me in the right direction, I would appreciate it.

Thank you.

It looks like this?

10.0.1.x->-> Corp. ASA L2L tunnel - >->-> 192.168.1.x 3560 172.16.x.x

and that you can currently communicate via the tunnel between 10.0 and 172.16? In order to communicate between 10.0 and 192.168.1, you will need to define this interesting traffic and add it to your crypto and nat exemption acl.

Error of tunneling traffic to 2 networks on the same link?

Hi all

Here is my list of current access to bring up my VPN tunnel. Everything works fine with it, but I have several networks from the source router. How to encrypt traffic from the same source router going to the same router by peers. Do I have to create a different ACL or can just add another license to the current ACL statement?

INT_Traffic extended IP access list
IP address 172.16.0.0 allow 0.0.255.255 172.17.0.0 0.0.255.255

Can I change the ACL above to this? Every time I add the second permit States below, I get the error below.

R2 #.

(1) you can not configure the same subnet for the subnet source and destination. Each end of the VPN must be unique. Therefore, you cannot add "ip 172.30.3.0 allow 0.0.0.255 172.30.3.0 0.0.255" to the ACL INT_Traffic.

(2) If you add another row of ACL under INT_Traffic, you also add the same image mirror ACL on the VPN peer device. You can not simply add the ACL on the router, because the other router wouldn't know the newly created ACL, so this will not work.

You can add the following line under INT_Traffic ACL:

IP address 172.16.0.0 allow 0.0.255.255 172.30.4.0 0.0.0.255

But you must also add the image mirror ACL on the device VPN peer as follows:

IP 172.30.4.0 allow 0.0.0.255 172.16.0.0 0.0.255.255

But, Yes, you can add several lines ACL under INT_Traffic if you want to encrypt via the VPN tunnel. Just make sure that the 2 points above.

Hope that helps.

Can not reach the internal network on the VPN

Hello

So I've been setting up an ASA5510 to the best of my knowledge to allow the VPN to our internal network access and its riches. IPSEC is configured correctly.

When connected I get an IP address from the VPN subnet with success, but I can't reach all internal hosts (failed pings). Also, I noticed that my default gateway uses a VPN subnet IP address.

I have followed the guide Wizard and configuration Online but am still in the dark... it's all a bit new to me!

I'll post the config if you need to see.

Any help would be appreciated!

Hi, just a few things I noticed. What group are you testing with? The tunnel of split for the two groups should be a standard ACL, well it doesn't have to be, but it is generally. I suspect that it doesn't because the ACL is defined in the wrong direction. You can therefore remove the first line of the RemoteVPNAccess of the ACL or replace it with a standard ACL. I recommend using a standard ACL.

Also applies similarly to your nat not and inside the ACL, they should be allowing the subnets the to address of the pool. So you can delete the second line of the ACL sheep and ' inside_access_in access-list extended ip 10.10.200.0 allow 255.255.255.0 everything ' inside ACL.

Also any tunnel or use a tunnel of split ACL but not both and also try to remove the filter from vpn, we can get to that after we have connectivity.
