Split tunneling ACL in easy VPN

Hello

When you look at the following example:

http://www.Cisco.com/en/us/products/SW/iosswrel/ps1839/products_feature_guide09186a0080087d1e.html#1015440

I noticed that the split tunneling ACL defined under the "crypto isakmp client configuration group cisco of" are:

access-list 199 permit ip 192.168.1.0 0.0.0.255 any

access-list 199 permit ip 192.168.3.0 0.0.0.255 any

And the local pool assigned to the customer to fred:

192.168.2.1 192.168.2.10

Is the above mentioned access list not the access list incorrect because there is no mention of 192.168.2.1 to 192.168.2.10?

The statement in the license should say the VPNclient that only traffic 192.168.1.0 AND 192.168.3.0 * should * be encrypted and jumped into the tunnel. Not all traffic since?

If the correct access list would read as follows:

access-list 199 permit ip any 192.168.1.0 0.0.0.255

access-list 199 permit ip any 192.168.3.0 0.0.0.255

Or am I wrong?

Hello

This list (mentioned in the doc) would work fine, but it's better if you use 192.168.2.0 24 in the destination network to be entered specific or specific for all these 10 IPs (.1-->. 10.

Thank you

VPN without split tunnel

Hello everyone

I have setup a VPN connection, which I can connect to. For all customers of connection, I want to give them an IP (from a subnet maybe) and let them use this IP address for all that they do.
Therefore, this:

and not current:

My inside is 192.168.1.0
My VPN IP pool is 192.168.30.5 - 200
My server (DNS, files, Web site) is 192.168.1.222

Here's my setup. I scored what I thought might have something to do with it:

Hello

Change Split Tunnel VPN in full Tunnel VPN, you have really do much in your configuration.

Seems that have already changed you the 'tunnelspecified' 'tunnelall' in configurations of the 'group policy' . You can delete the setup but that defines the ACL of Split Tunnel

attributes of Group Policy HSSvpn
No split-tunnel-network-list value Split-Tunnel-ACL

Seems that you use an internal AAA server to manage authentication rather than on the SAA. I guess if you want to assign a specific IP address for VPN user/username, then it must be done on the side Server?

If you had the "username" on the SAA configurations you can set it up under its framework which "username" IP address gets when he or she connects with the VPN Client.

As naturally as you start using the complete Tunnel and all traffic from the VPN Client starts to get in the tunnel to the ASA you will need a NAT for VPN Client users Internet traffic. You can configure this NAT like this for example:

network of the VPN-POOL object
192.168.30.0 subnet 255.255.255.0

interface of VPN-POOL dynamic NAT (outside, outside) after auto source

Note that this is a manual of NAT / double NAT statement real "nat" IS NOT inserted under the 'object' , but the 'object' is rather created it can be used in the "nat" command. I see that your other dynamic PAT configurations are configured with NAT Auto / object NAT network. You can do this like that too if you wish. Personally I do like that.

But as I said before, it seems that you have already configured the VPN to be full of Tunnel. It is perhaps not as it is? While it is connected with VPN, you should be able to check the secure routes (or something like that) section to see if it says "0.0.0.0" If Yes, then it should be tunneling all traffic.

Hope this helps :)

Restrictions of ASA Anyconnect for Split Tunneling network list

Hello

I have a question. We use Cisco ASA 5520 9.1.1 firmware version with configure SSL VPN Anyconnect(Anyconnect client version 2.5.605).)

We use the big Split Tunneling access-list with 200 ACEs.

If I add more than 200 entries in the list of access and then I connect to the VPN, and after that, we will see that only 200 entries have been added to the routing table.

So my question is... There is a limit for Split Tunneling ACL when you use the Anyconnect client?

Thank you

Hello
```
This is very well document in one of internal bug at Cisco . Unfortunately, as it is internal I will not be able to share the same with you. The only workaround available as of now is to combine your networks and make the list as small as possible covering all the required network you need which is less than or equal to 200
```
Thank you

Split Tunnel problem.

Hello.

All started to play with split-mining.

So far so good.

I can access the server when the Tunnel of splitting is disabled, and my itinerary looks very good. But cannot access the internet.

I can not access the server when the Tunnel of splitting is enabled, my itinerary seems wrong. But can access the internet.

I think it's my access list the problem (also tried to overthrow).

split_test list extended access allowed host 4.4.4.4 ip 10.10.253.0 255.255.255.0

attributes of the strategy of group test_policy

Split-tunnel-policy tunnelspecified

value of Split-tunnel-network-list split_test

I read that I can't filter on the ports during the shared use of tunnelling, is this correct?

I have attached a quick drawing of the installation.

Best regards, Søren.

Hello

Then you can use the following version of above indicate changes in configurations

attributes of the strategy of group test_policy

No split-tunnel-network-list split_test value

No list of extended split_test access not allowed host 4.4.4.4 ip 10.10.253.0 255.255.255.0

host of access TUNNEL of SPLIT standard allowed 4.4.4.4 list

attributes of the strategy of group test_policy

no value of split-tunnel-network-list SPLIT-TUNNEL

The above configuration would be basically set up the VPN Client connection so that connections for ONLY the IP 4.4.4.4 the VPN connection will be provided by the user.

As I understand it, the traffic of users to the destination server would only be encrypted between the Client and the ASA. From there it would be just like any traffic between hosts on the external network. Except of course your ASA has a separate VPN L2L connection on the site where the Server 4.4.4.4.

Even if the above Split Tunnel ACL configuration is correct, you will still need to manage the NAT for VPN Client users. To determine the NAT configuration correct, I need to know the version of the software of your ASA and the current dynamic PAT rule for internal users, for example if the VPN users are supposed to use the same public IP address for their IP NAT address.

Also, you will at least have to add this configuration on the SAA

permit same-security-traffic intra-interface

This will allow connections to VPN users enter through the 'outside' of the interface and head to this same ' outside ' interface. It is not possible without the above configured command even if all other configurations were correct.

access list of split tunneling

Hello

I have some problems on ASA 5520 split tunneling configuration.

Here's the scenario:

Number of remote users connects ipsec with ASA 5520 (in central) using ubuntu vpnc-client.

Split tunneling is used, in order to allow remote users to surf the Internet using their ISP.

The goal is to remove the possibility for ssh/telnet servers within the local enterprise network for remote users.

Here is a part of the config:

internal REMOTE_gp group strategy
attributes of Group Policy REMOTE_gp
VPN-idle-timeout no
Protocol-tunnel-VPN IPSec
Group-lock no
Split-tunnel-policy tunnelspecified
value of Split-tunnel-network-list REMOTE_split

tunnel-group type REMOTE access remotely

tunnel-group REMOTE General attributes

authentication-server-group RADIUSGR

Group Policy - by default-REMOTE_gp

pre-shared-key *.

ISAKMP keepalive retry threshold 15 10

RADIUS protocol AAA-server RADIUSGR

REMOTE_split list extended access deny tcp 192.168.0.0 255.255.255.0 ssh telnet rank everything

permit access ip 192.168.0.0 scope list REMOTE_split 255.255.255.0 192.168.100.0 255.255.255.0

ip subnet ##192.168.100.0/24 - where from Radius Server to allocate ip addresses to remote users.

INSIDE_LAN_in list extended access deny tcp 192.168.0.0 255.255.255.0 eq ssh 192.168.100.0 255.255.255.0

permit access ip 192.168.0.0 scope list INSIDE_LAN_in 255.255.255.0 any

It has nat enabled on the interface, but there is a special instruction in nat0 ACL for 192.168.100.0 subnet

permit access ip 192.168.0.0 scope list INSIDE_LAN_nat0_outbound 255.255.255.0 192.168.100.0 255.255.255.0

The problem is that the remote users can easily ssh and telnet servers in network INSIDE_LAN. Everything I put in INSIDE_LAN_in ACL, remote users still have full access to this network. Restrictions in the REMOTE_split ACL do not work either.

You must configure vpn-filter rather to block telnet and ssh access as follows:

Remote filter access list deny tcp 192.168.100.0 255.255.255.0 192.168.0.0 255.255.255.0 eq 22

Remote filter access list deny tcp 192.168.100.0 255.255.255.0 192.168.0.0 255.255.255.0 eq 23

distance-filter 192.168.100.0 ip access list allow 255.255.255.0 192.168.0.0 255.255.255.0

attributes of Group Policy REMOTE_gp

VPN-value filter-remote control

Split tunnel acl has the following statement and it should be extended to standard ACLs instead of:

REMOTE_split list of permitted access 192.168.0.0 255.255.255.0

Hope that helps.

Easy VPN between two ASA 9.5 - Split tunnel does not

Hi guys,.

We have set up a site to site vpn using easy configuration vpn between ver 9.5 race (1) two ASA. The tunnels are up and ping is reached between sites. I also configured split tunnel for internet traffic under the overall strategy of the ASA easy vpn server. But for some unknown reason all the customer same internet traffic is sent to the primary site. I have configured NAT to relieve on the side of server and client-side. Please advise if no limitation so that the installation program.

Thank you and best regards,

I have the same question and open a support case.

It's a bug in the software 9.5.1. See the bug: CSCuw22886

Cisco easy VPN access Internet without Split Tunnel

Hey guys

IM wondering if anyone has a config that can help me get access to internet via an easy vpn tunnel on a cisco 877 router.

Basically, we are traveling to be users able to use the internet through vpn, rather than using split tunneling. The reason for this is that we have several sites that are attached by lists of external IP access for some services.

We hope that mobile users to interact with these sites through the central router and use external IP of access routers secure sites.

I hope that makes sense. I know that we can use a proxy but we also use other services of bases no proxy on these sites, it would be rather routed direct access.

Thank you

Luke

Hi Luke,.

Please use the installation of the client VPN (complete tunnel) link below.

What is is it possible to use the acl extended for split tunneling on ASA?

I'm setting up VPN IPSEC RA on SAA and I would like to know if it is possible to use the ACL extended as part of the split tunneling?

Thank you!

Yes, you can use the extended ACL. See this example:http://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-nex...

Disable Split Tunneling - SAs are not when I change crypto ACL

Hello!

When I change my ACL Crypto I receive an error message in phase I: "PROPOSAL_NOT_CHOSEN NOTIFIER' of IKE. I do this to disable the ST and get all the hollow tunnel traffic. Please see the config below:

I changed the ACL 115 to so I can disable split tunneling, and it looks like this:

access-list 115 permit ip 10.10.10.0 0.0.0.255 any

access-list 115 deny ip any one

What is a failure? I have donthink the crypto ACL must be the same?

OK, you use a card dynamic encryption on your head just as I suggested, so that's fine. What you have done, which is causing your problem (and usually causes more problems than it's worth), is to assign an access list to the dynamic encryption card. It is not necessary, because with a dynamic encryption the router head card accept any model of traffic the remote router sends.

In your case since you changed the remote router to be 'all', it is no longer maps to the 115 ACL on the head and now is failing.

Way easier around it is simply to remove the 'match 115' address card dynamic encryption on the head. This will not affect any of your other tunnels and allow the remote router to establish a tunnel.

The exact commands you would use are as follows:

> crypto dynamic-map PERSONAL 10

> no address for correspondence 115

Hello

First of all - thanks to all who post here. I often browse the forums and search for help here and its very useful, so a big pat on the back for all who contribute. My first post, so here goes...

I've got my ASA 5505 v8.2 configured to allow the AnyConnect. This works. Client can connect and access remote systems via VPN. What causes me a massive headache, is the customer loses internet connectivity. I played a bit with my config a bit so what I am about to post that I know for sure is incorrect, but any help is greatly appreciated.

Notes

1. the router was set up for a VPN site to site standard that is no longer functional, but as you can see all the settings are always in the router.

2. the router also a DMZ configuration has to allow access to the internet with the help of the DMZ to some customers

Thanks for any help!

In your group strategy, you specified the ACLs that should be used for split Tunneling, but you forgot to change the policy, so the ASA always uses tunnel-all. Here's what you'll need:

Split tunneling VPN site-to-site

Dear all,

I have two ASA 5510 with VPN site-to-site, I can send all Internet traffic to the central site (HQ),

How to set the split tunneling to access Campus LAN (192.168.2.0/24) of LAN2.

Thank you in advance.

Best regards

Zoltan

You can have 'decline' instruction on your ACL crypto and he will deviate the traffic is encrypted to the site-to-site VPN tunnel.

For ASA 1:

access-list extended 100 permit ip 10.10.16.192 255.255.255.192 10.10.16.128 255.255.255.192

access-list extended 100 permit ip 10.0.0.0 255.0.0.0 10.10.16.128 255.255.255.192

access-list extended 100 permit ip any 10.10.16.128 255.255.255.192

For ASA 2:

access-list extended 100 permit ip 10.10.16.128 255.255.255.192 all

Hope that helps.

Remote VPN: split tunnel filtering

Hello!

The question is about the split tunnel filtering capabilities without using the vpn-filter.

Suppose, we have ASA configured for remote VPN tunneling with split without VPN filter.
- 10.0.0.0/8 is the private netwrok.
- 10.1.0.0/24 is the private network, defined in the split tunnel
- 172.16.1.0/24 is the VPN SECURE network
When the remote client connects, it receives the routes to the private network (10.1.0.0/24).

What happens if the remote client adds the route to a private network (which is not defined by a tunnel of split) by itself (e.g. 10.2.0.0/24)?

Our test LAB, we can see that the customer does not have access to 10.2.0.0/24.

Where the place in this case filtering?
- By default, all vehicles coming from VPN, bypasses all ACLs configured on interfaces ASA.
- Filter VPN is not configured.
- Nat0 don't traffic 10.0.0.0/8 to 172.16.1.0/24 NAT
- of the sh ip cry his on the VPN server, we can see, this ident is 0.0.0.0/0
  - local ident (addr, mask, prot, port): (0.0.0.0/0.0.0.0/0/0)
  - Remote ident (addr, mask, prot, port): (172.16.1.1/255.255.255.255/0/0)
The ACL of split tunnel is capable for remote client traffic filtering?

I understand that your question is in what regards the IPSec VPN Client, no AnyConnect VPN Client, however, I think that the behavior of the split tunnel is the same.

Here's the answer to your question:

https://supportforums.Cisco.com/docs/doc-1361#Q_How_does_the_AnyConnect_client_enforcemonitor_the_tunnelsplittunnel_policy

A. AnyConnect applies the policy of tunnel in 2 ways:

Monitoring of track 1) and repair (for example if you change the routing table), AnyConnect will restore it to what has been configured.

(2) filtering (on platforms that support filter engines). Filtering ensures that even if you can perform a kind of injection of the route, the filters would block packets.

Easy VPN - acl

Hello

There is an "acl" parameter that is not clear to me, it is configured at customer site:

Crypto ipsec VPN ezvpn client

connect auto

Cisco key band EASYVPN

client mode

peer 10.0.0.1

username cisco password cisco

xauth userid local mode

ACL 101

Everything that I added to the ACL 101 tunnel is always present. I found a description:

Step 6
ACL {name - acl |} ACL-number}
Example:

Device (ezvpn-crypto-config) # acl acl-list1

Specifies several subnets in a VPN tunnel.

"Specifies several subnets in a VPN tunnel". -what it means, source?

I tried to use this setting, and I added the access list:

access-list 123 allow ip 10.10.10.0 0.0.0.255 host 20.0.0.20

access-list 123 allow ip 50.50.50.0 0.0.0.255 host 20.0.0.20

where 10.10.10.0 and 50.50.50.0 are source and 20.0.0.20 is the destination.

When I ping with source 10.10.10.3 (physical int) for 20.0.0.20 - numbers of BA & desc packages grows.

but when I ping with source 50.50.50.50 (int loop) for 20.0.0.20 - I see that it wasn't to push into the tunnel.

Could someone explain how the work parameter and for what is it?

Thank you

Hubert

Hubert,

Ref:

http://www.Cisco.com/en/us/docs/iOS-XML/iOS/sec_conn_esyvpn/configuration/15-2mt/sec-easy-VPN-rem.html

in client mode several subnets are not supported, nor what they sense.

You specify what internal subnets of announcement to the server that are configured behind this device.

In client mode, the server sees only the assigned IP address.

M.

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.

I think that you made a mistake with your ACL name. the ACL applied is "VPN-ACL-SPLIT" which is an empty ACL. You must switch to that of "ACL-VPN-SPLIT" that has the entry "ip 192.168.1.0 allow 0.0.0.255 192.168.1.0 0.0.0.255" inside.
