VPN site to Site with restrictions (vpn-filter)

VPN site to site, I installed and it works fine and two site can meet but I question after the vpn enforcement - run under Group Policy

restrict users in the local site for dial-up networking with specific tcp ports, the vpn does not not like after order question «sh l2l vpn-sessiondb»

This works but users can't access something in the remote site

Note > after rising online in ACL at the end with this

US_SITE ip access list allow a whole

new to works well again

example of a line of Access-List

US_SITE list extended access permit tcp host 10.68.22.50 host 192.168.10.23 HTTP_HTTPS object-group
US_SITE list extended access permit tcp host 10.68.22.50 host 192.168.10.24 HTTP_HTTPS object-group

local network: 10.68.22.50

remote network: 192.168.10.24

is that correct or not?

attributes of the strategy group x.x.x.x
value of VPN-filer US_SITE

tunnel-group General y.y.y.y
x.x.x.x by default-group-policy

Note: allowed sysopt active vpn connection

The syntax on ACL that is used as a vpn-filter is different from what is normally expected. These VPN filters is not a direction, it should be noted the traffic we want to allow incoming and outgoing of the VPN in an ACL. The syntax for this is:

access-list X permit/deny REMOTE-DEFINITION LOCAL-DEFINITION

Example: You want to allow local users to access the RDP on the remote site:

access-list VPN-ACL permit tcp host 192.168.10.24 eq 3389 10.68.22.0 255.255.255.0

Disadvantage: This is all really confusing, and you can't afford things like Ping in one direction.

Site to Site VPN filter

I've set up a site to site VPN and I can't seem to get the VPN filter works. I've followed this document:

http://www.Cisco.com/image/gif/paws/99103/PIX-ASA-VPN-filter.PDF

I created an ACL and created an ACE with only traffic I want to allow. Then, I went to the site to site group policy and apply this filter. However, I can still ping remote network from a customer who should not be allowed. Remote network is 192.168.2.0/24.Here is my partial config:

Hello

First of all I would like to clarify that the group name used for one site to the other tunnel tunnel must be the ip address of the host "at least for the tunnels l2l static" it's tunnel-g were you must apply this "Test" group policy, configuring the filter seems perfect, but you must make sure that you apply the strategy of Group accordingly. Now, once you apply group policy to the correct you have to bounce the tunnel tunnel-g otherwise the new filter will not take effect, you can use the command "erase the crypto ipsec his counterpart x.x.x.x" generate some traffic and bring up the tunnel is again he should have the filter.

If you apply correctly and bounce the tunnel it will work.

You can check if the filter is applied with the command "show vpn-sessiondb detail l2l" and find the name of the ACL

Best regards, please rate.

the traffic in a vpn site-to-site tunnel restrictions

Hello

I have install a VPN site-to site between an ASA 5550 7.2 (3) and the external network of the contractor. I have set up the VPN using the wizard and it worked fine. The wizard has created the cryptomap acl see below

outside_2_cryptomap list extended access allowed object-group ip 10.0.0.0 LOCAL_IPS 255.255.255.0

where LOCAL_IPS is a group of objects containing our local subnets to be dug and 10.0.0.0/24 is the network of the remote end.

I'm trying to restrict the traffic tunnel at about 6 tcp ports, so I changed the acl (using the GUI as well from the CLI) to the following:-

outside_2_cryptomap list extended access permitted tcp object-group LOCAL_IPS 10.0.0.0 255.255.255.0 PERMITTED_TRAFFIC object-group

where PERMITTED_TRAFFIC is a group of TCP services containing the ports we'd like to tunnel.

As soon as I apply this acl (applied at the other end also) the tunnel down and or end it can re - open.

My question is - how do you restrict what traffic (tcp ports) that you want to send in the tunnel on the SAA?

Thank you

Andy

Two things are here according to you needs.

First you encrypt all the traffic on the network 192.168.204.0/24... do you intend to send all traffic on that subnet via the VPN? If this isn't the case, specify the remote subnet instead of using all the crypto ACL.

object network LAN subnet 192.168.204.0 255.255.255.0access-list outside_cryptomap_1 extended permit ip object LAN any

Second, you have not an exempt statement NAT so that encrypted traffic should not be translated. This statement would look like the following:
the object of the LAN network
192.168.204.0 subnet 255.255.255.0

being REMOTE-LAN network
255.255.255.0 subnet 192.168.100.0

VPN site to Site with an ASA behind Port Forwarding device

Hi, I want to configure a VPN from Site to site with an ASA with a public static IP adress and other ASA located behind a device with a public IP address that can forward ports to the ASA.

I have found no documentation for this configuration in the Cisco KB, anyone have a link for me or a brief description of the requirements?

Thank you

Tobias

Hello

ASA (v9.1) VPN from Site to Site with IKEv2 and certificates CEP/NDE MS

Hi all

I am currently a problem with VPN Site to Site with IKEv2 and certifiactes as an authentication method.

Here is the configuration:

We have three locations with an any to any layer 2 connection. I created each ASA (ASA5510 worm 9.1) to establish one VPN of Site connection to the other for the other two places. Setting this up with pre shared keys and certificates that are signed by the CA MS administrator manually work correctly.

But when we try to enroll these certificates through the Protocol, CEP/NDE his does not work.

Here are my steps:

1 configure the CA Turstpoint to apply to the certification authority

2. request that the CA through the SCEP protocol works fine

3. set up a Trustpoint and a pair of keys for the S2S - VPN connection

4. registration form identity certificate CA via the SCEP Protocol with a one time password works fine

5. set the trustpoint created as for the S2S - VPN IKEv2 authentication method.

Now I did it also for the other site of the VPN Tunnel. But when I ping on a host that is on a different location to make appear the Tunnel VPN - the VPN session is not established. In the debugs I see that there are a few problems during authentication of the remote peer.

On the MS that I see that the certifactes of identity for both ASAs are communicated and not revoked or pending state. The certificate based on the model of the "IPSec (Offline).

When the CA-Admin and a certificate me manually based on a copy of the model of "Domaincontroller" connection is successfully established.

So I would like to know which is the correct certificate for IP-Sec peers template to use for the Protocol, CEP and MS Enterprise CA (its server 2008R2 of Microsoft Enterprise)?

Anyone done this before?

ASA requires that the local and Remote certificate contains EKU IP Security Tunnel Endpoint (1.3.6.1.5.5.7.3.6) (aka IP Security Tunnel termination). You can create a Microsoft CA model to add.

If you absolutely must go with the 'bad' cert, there is a command

ignore-ipsec-keyusage

but it is obsolete and not recommended.

Meanwhile at the IETF:

RFC 4809

3.1.6.3 extended Key use
```
Extended Key Usage (EKU) indications are not required.  The presence
or lack of an EKU MUST NOT cause an implementation to fail an IKE
connection.
```

Need help with the configuration of the Site with crossed on Cisco ASA5510 8.2 IPSec VPN Client (1)

Need urgent help in the configuration of the Client VPN IPSec Site with crossed on Cisco ASA5510 - 8.2 (1).

Here is the presentation:

There are two leased lines for Internet access - a route 1.1.1.1 and 2.2.2.2, the latter being the default Standard, old East for backup.

I was able to configure the Client VPN IPSec Site

(1) with access to the outside so that the internal network (172.16.0.0/24) behind the asa

(2) with Split tunnel with simultaneous assess internal LAN and Internet on the outside.

But I was not able to make the tradiotional model Hairpinng to work in this scenario.

I followed every possible suggestions made on this subject in many topics of Discussion but still no luck. Can someone help me here please?

Here is the race-Conf with Normal Client to Site IPSec VPN configured with no access boarding:

Adding dynamic NAT for 192.168.150.0/24 on the external interface works, or works the sysopt connection permit VPN

Please tell what to do here, to pin all of the traffic Internet from VPN Clients.

That is, that I need clients connected via VPN tunnel, when connected to the internet, should have their addresses IP NAT'ted against the address of outside internet2 network 2.2.2.2 interface, as it happens for the customers of Campus (172.16.0.0/16)

I am well aware of all involved in here, so please be elaborative in your answers. Please let me know if you need more information about this configuration to respond to my request.

Thank you & best regards

MAXS

Hello

If possible, I'd like to see that a TCP connection attempt (e.g. http://www.google.com) in the ASDM logging of the VPN Client when you set up the dynamic NAT for the VPN Pool also.

I'll try also the command "packet - trace" on the SAA, while the VPN Client is connected to the ASA.

The command format is

packet-tracer intput tcp

That should tell what the SAA for this kind of package entering its "input" interface

Still can not see something wrong with the configuration (other than the statement of "nat" missing Dynamics PAT)

VPN site-to-site with pppoe ADSL connection

Dear

I would like to know - is it possible to connect two 5505 ASA in VPN site-to-site with 1 site using the pppoe ADSL connection?

A (static IP) site

Site B (ADSL pppoe, DHCP)

Site has < site="" to="" site="" vpn=""> > Site B

Best regards

Alan.

Configuration of site B should be the same as all the other side than peers with static end.

The different configuration would be on Site A as he will accept a VPN to a dynamic counterpart.

Unfortunately, I have no configuration example to show you on ASDM.

You must ensure that there is no NAT 0 ACL statement because it will take precedence over the static NAT.

You don't need:

Global 172.26.0.1 - 172.26.0.254 10 (outside)

NAT (inside) 10 access-list nattoyr

Because it will be replaced by the static NAT.

In a Word is enough:

nattoyr to access ip 10.0.0.0 scope list allow 255.255.255.0 10.1.252.0 255.255.255.0

Tunnel VPN site to Site with DDNS

I have a hub site that has a static ip address and a remote site with DDNS. I am building a Site to Site tunnel between them, I can do this with the static ip address, but when he changes the tunnel breaks down, so I need a way to the ASA to know when this ip address changes. How can I do this?

Thank you

To my knowledge, DDNS for VPN is supported only on router IOS not on ASA.

If you use ASA on the head of network, you may need to use EasyVPN

http://www.Cisco.com/en/us/partner/products/ps6120/products_configuration_example09186a0080912cfd.shtml

EasyVPN VPN must be started from the remote site.

VPN-filter seems to work in both directions

I have ASA 5520, Version 8.4 (3)

I set up VPN site to site vpn-filter for filtering of communications

I use this example:

http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/products_configuration_example09186a00808c9a87.shtml#configs

VPN connection did not work, so I applied last line to my vpn-filter ACL:

access list acl-L2L-ORANGE extended deny ip any any interval notification log 60

I am very confused, because I heard syslog message:

% 5-ASA-106102: acl-L2L-ORANGE access list denied tcp to the user "" inside/10.1.61.51(60748)-> outside/213.151.208.154(4490)

It seems to me, this vpn filter filter my indoor to outdoor advertising.

Communication which is sent from inside the TUNNEL.

Worse still, my ACL include this line

access list acl-L2L-ORANGE line 1 scope permitted tcp 10.1.61.51 host 213.151.208.154 (hitcnt = 0)

How can it be possible?

Hello

If you want to get rid of the problems and complexity can be used access VPN filter lists you can run the following command

No vpn sysopt connection permit

It would make is that all connections from the remote site VPN L2L would be subject to check rule access-list on the external interface of your ASA in the same way your local network traffic heading for the remote site VPN L2L is checked by your inside of the access list interfaces

But if you go this route, you will need to consider that you will need to open the traffic for possible existing (Client and VPN L2L) VPN connections on your external interface to access list before running the above command.

At least in this way you encounter the problem that you actually more open that you expect with the type of VPN ACL filter. And as I said it is not quite as complicated to manage.

I must say however that I do not use the two ways depending on the environment that I am setting up.

8.2 ASA vpn filter for connections l2l

I have a vpn-filter set to my police L2L. The remote site uses a Cisco 1811 router and the main hub is a Cisco 5580. I already have an acl of vpn-filter in place on an existing L2L connection which works fine. The only question is, when I make changes to the ACLs for add/remove access, I have to reload the whole of the tunnel until the changes take place.

My question is, are at - it a command to reload the access control without destroying the tunnel?

Hi Jeffrey,.

Design whenever there are changes in the attributes of Group Policy (including the vpn-filter, dns ip of victories or vpn-Protocol etc.), you need to reset the respective tunnel while phase 2 is negotiating with the newly added policy. The command to clear a specific tunnel is: -.

his clear crypto ipsec peer

For more details on the command, please see the link below

http://www.Cisco.com/en/us/docs/security/ASA/asa80/command/reference/C3.html#wp2133652

So, to answer your query wasn't there command is not to reset the access control. There had been such a command you would still back the tunnel to trigger negotiations ipsec with the new group policy settings.

5 sites with UC500 to BE6K

We have 5 sites that use all UC500 systems at this time and wish to update but don't know exactly what we need to move forward.

-Main site: UC560 with 101 user 3 remote sites with 1 each, phone calls go to SIP trunk.

2nd - site: UC540 with 12 users

3rd - site: UC540 with 11 users

4th - site: UC540 with 10 users

All of these sites are related to IPSEC site to site VPN and each call passes through the UC560 first and then redirected to other sites.

All the suggestions/help is appreciated.

Thank you.

Yes, you can have a 6K, it supports up to 60 locations and you would centralise control of call for all your sites.

One can explain the value command Anyconnect VPN etc. "vpn-filter"?

Hello

In Anyconnect VPN, there are two commands that I pointed out wild "BOLD". I checked it with "?" behind the command. But I still don't understand it and why it should be used here. I hope someone can explain it to me. Thank you

Internal authority of group-policy

attributes of authority-group policy

VPN-filter Access_List value

clientless ssl VPN tunnel-Protocol

value of group-lock Third_Party

Split-tunnel-policy tunnelspecified

value of Split-tunnel-network-list County_Access

-Here is what I checked:

Enter the name of an existing tunnel group for users to connect with group-lock

Enter the name of an ACL configured to apply to VPN-filter users

Vpn-filter adds an extra layer of security for VPN remote access by adding an access list to all traffic that comes from remote users.

For example, you can restrict to a subnet (which you can do in the tunnel-group) can still say that the HTTP servers, B and C (for which you would use the access list specified by the filter-vpn).

The group-lock prevents users defined to choose policies other group available in the drop-down list.

For example, you can restrict VPN users generally use a group without restriction for IT admins. Or allow only external suppliers to connect to a group designated to them that restricts access to a set of resources in the DMZ.

PIX v6.3 Site-to-Site with policy NAT

Hi guys,.

I need to set up a site to site with nat because we have overlapping subnet at the other end.

They need access to both servers on our network with IP static.

Site A: 192.168.100.0/24

Site b: 192.168.200.128/25

The other site has chosen this network for NAT: 10.200.50.0/28

I need to translate

192.168.100.10 > 10.200.50.2

192.168.100.20 > 10.200.50.3

through the tunnel

That's what I've done so far, will this work? Any problem that may appear with this config?

Crypto ACL:

VPN ip 10.200.50.0 access list allow 255.255.255.240 192.168.200.128 255.255.255.128

Policy_NAT1 list of allowed access host ip of 192.168.100.10 192.168.200.128 255.255.255.128

Policy_NAT2 list of allowed access host ip 192.168.100.20 192.168.200.128 255.255.255.128

NAT (inside) 10 access-list Policy_NAT1 0 0

NAT (inside) 11 access-list Policy_NAT2 0 0

overall 10 10.200.50.2 (outside)

Overall 11 10.200.50.3 (outside)

Thanks in advance!

Hello

Your configuration looks very good.

Although I guess it's a dynamic configuration policy NAT/PAT.

Incase you want to configure static policy NAT, you need to change a bit. I mean if you wanted a NAT configuration allowing to form bidirectional connection. Both from your site to the remote site and the remote site to your side. You can always use the same ACL you have configured, but you would use the "static" configurations.

public static 10.200.50.2 (inside, outside) - Policy_NAT1 access list

public static 10.200.50.3 (inside, outside) - Policy_NAT2 access list

Review with the static NAT to politics and the dynamic policy NAT/PAT which would be if these hosts have static NAT configured at the direction of the 'outside' interface while static NAT would cancel both of these configurations.

If you use the political dynamic NAT and had also a static NAT for the host, then you would have to change from the above static NAT in a policy to override the static NAT.

And with the foregoing in mind possible existing static NAT and new static NAT of policy might have some problems as a whole. In this case the scheduling of NAT rules would determine if static NAT of the policy has been applied already. If you already had the configured static NAT then it would nullify the political new static NAT:. The solution would be to remove the static NAT and enter it again. This would move the static NAT once the static NAT to policy in the order that they appear on the CLI format configuration and, therefore, static political NAT would work for the specified destination and addresses the static NAT for all other destination addresses.

Hope I made any sense

Feel free to ask more if necessary while
