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:

permit Test access extended list ip 192.168.2.0 255.255.255.0 192.168.1.2 host
Trying to deny a range ip extended access list

Group Policy internal Test
Test group policy attributes
value of VPN-Filter Test

tunnel-group Test_tunnel type ipsec-l2l
attributes global-tunnel-group Test_tunnel
Group Policy - by default-Test

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.

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.

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.

Port of filter IPsec site to site VPN

Hello guys!

I have configured a VPN Site to Site, as follows: (for the access list)

Local: 192.168.0.0/24

Distance: 10.0.0.0/24

So, I have this configuration:

VPN-Test line 1 permit access list extended ip 192.168.0.0 255.255.255.0 10.0.0.0 255.255.255.0

But I would like to leave just tcp/80 on my remote to connect to my Local. (because now 10.0.0.0/24 accesses all in my 192.168.0.0/24)

How can I do? (I tried to change the list of access VPN-Test under ASDM, Configuration, ACL Manager, but no way)

I should create a rule in the external interface, such as:

Source: 10.0.0.0/24

DST: 192.168.0.0/24

Protocol: tcp/80

How can I do?

Thank you

Diego

By default, the external ACL is not evaluated for VPN traffic. Instead, you configure a new ACL that is applied as a "vpn-filter' to the group policy for your connection.
```
 access-list VPN-FILTER-XXX permit tcp any any eq 80 ! group-policy GP-VPN-XXX attributes vpn-filter value VPN-FILTER-XXX ! tunnel-group a.b.c.d type general-attributes default-group-policy GP-VPN-XXX 
```
In the ACL, you need not specify the networks, as the tunnel cannot carry anything other what is specified in the crypto-ACL. But of course you can enter them if you want to:
```
 access-list VPN-FILTER-XXX permit tcp 10.0.0.0 255.255.255.0 192.168.0.0 255.255.255.0 eq 80
```

First shot at the site to site VPN fails

This is my first attempt at establishing a VPN site-to site on ASA 5505 s. Fortunately, I'm able to do on the bench and not on the real sites. As soon as I can verify connectivity, I'll move them to the physical sites.

The two ASAs are running 8.3 (1). I tried with ASDM and I tried via CLI. I don't seem to be able to do anyway.

An ASA is configured with the address of WAN 10.1.52.1/24, address LAN 192.168.52.1. Another ASA is set up 10.1.200.1/24 WAN, LAN 192.168.200.1. Because they are on the bench (lab / whatever) there is a single cable connects the two WAN ports. I have a single workstation on each LAN to test connectivity. I CAN'T successfully ping the WAN ASA (10.1.52.1) from the workstation on 192.168.200.1 and vice versa. I'm NOT able to ping the workstation on 192.168.200.1 or of the ASA 10.1.200.1 (192.168.52.1) LAN and vice versa.

Here are the configs for the two and some recording of debug output:

Match your configuration with my setup and make changes. Filters VPN are not allowed because you are not filtering anything. Remove the filter VPN at both ends, and then try to ping through the VPN. Also if you ping forms inside the interface inside the interface of the other device, and then make sure that access management is enabled on both interfaces, it will not respond to ping requests.

How to check if access to administration are enabled or not is by running the command:

See the human race

If you get anything enter command 'inside man' and then run ping.

Let me know if it helps.

Site to site VPN ASA2ASA funny crypto ACL behavior

Hello

I use a VPN site-to site between two ASAs. It works but it should not work, in my opinion, there is a bug. The thing is that when I set the traffic is encrypted in an ACL, this traffic is denied and the tunnel doen't work. If I remove the ACL entries, I'm really interested in encryption, it works...

Thus, for example.

I affermirai a tunnel between the two ASAs and specify

access allowed extended VPN ip host 172.16.0.60 list 172.20.24.60

colt_map card crypto 20 matches the VPN address

When I have it, there is no traffic allowed between 172.16.0.60 and 172.20.24.60. And when I do:

VPN access list extended deny ip host 172.16.0.60 172.20.24.60

access allowed extended VPN ip host 172.16.0.59 list 172.20.24.59

Can I get a communication between 172.16.0.60 172.20.24.60 of the host, but not between 172.16.0.59 the host 172.20.24.59.

It seems very weird to me. I was wondering if anyone had this behaviour before or she could explain it?

Thanks in advance.

Yes.

In Janan all traffic VPN is not checked against the external ACL because of a single command: sysopt connection permit VPN

You can see if this command is enabled by practice: sh run all the sysopt

If you remove this command: no sysopt permit vpn connection

then, all VPN traffic is checked against the ACL interface (and you can only allow what you need).

A better approach is to let the sysopt connection permit-vpn default and create a vpn-filter ACL that is applied to group policy for tunnel groups you need.

Several subnets in the site to Site VPN

Hi guys,.
I would like to set up a site of tunnel VPN stie with several subnets. I could not find a configuration which is my problem. I hope you can help me with the solution.
You can find my design network attach to this subject.
This is my setup on the ASA:

(1) NAT excemption for network traffic, go to the Site to site VPN.

This configuration is correct to allow both subnets on each side of the VPN tunnel to communicate with each other.

192.168.31.0 subnet cannot communicate with 192.168.10.0
192.168.38.0 subnet cannot communicate with 192.168.15.0

Hello Jay,

I went during the configuration of the two aircraft and noticed a few errors on the configuration of the SAA. Details here:

(1) the access list configured for VPN traffic is named ACL_STSVPN-US, however the address for correspondence configured on the map encryption uses a group of objects name instead:

address for correspondence card crypto 10 CM - STSVPN STSVPN-US

You must change this setting to avoid any problems with the negotiation of traffic:

no matching address card crypto 10 CM-STSVPN STSVPN-US

10 CM-STSVPN crypto card matches the address ACL_STSVPN-US

(2) you also have the same error on the configured vpn filter. However, you could not use the access list ACL_STSVPN-United States for VPN filter since the ASA will filter incoming packets only. In this case the appropriate ACL will be configured for remote network (ROUTER) to local networks (ASA). It will look something like this:

access-list VPN_filter extended permitted ip object-STSVPN-US group LOCAL STSVPN

access-list VPN_filter extended permitted ip object-STSVPN-US group LOCAL STSVPN

Group Policy attributes GrpPolicy-STSVPN-US
VPN-Filter VPN_filter value

Keep in mind that the VPN filter is in the rules that determine whether to allow or deny packets of data tunnelees coming through the device security, based on criteria such as the source, destination, and Protocol address address. If you want to use the IP Protocol, the filter will not make a difference.

(3) group 14 of the PFS is configured on the router crypto map, but not on the SAA. You need to even add it in the card encryption ASA or remove it from the router.

ASA:

card crypto 10 CM-STSVPN set group14 pfs

Router:

crypto CM card. 30 VPN ipsec-isakmp

No group14 set pfs

Hope this help you to raise the tunnel,

Luis.

Site to Site VPN problem ASA 5505

Hello

I have a strange problem with a site to site VPN. I configured it completely and I added 3 of my internal networks to be encrypted and access the remote network across the tunnel.

For some reason, I can access the remote network of only two of the three internal networkls that I've specified.

Here is a copy of my config - if anyone has any info I would be happy of course.

Thank you

Kevin

can you confirm if we have the exact reflection of crypto acl at the other end

I feel may be you have a 24 10.239.192.0 255.255.255.0 on the other end in the remote network

can you please confirm that

also a reason, why you use 10.239.192.0 255.255.255.128 and 10.239.192.128 255.255.255.128 instead of 10.239.192.0 255.255.255.0

But the servers NATTED (10.17.128.x <->31.10.10.x) does not work.

Hello

I think you could have said the original question in a way that could be missleading. In other words, if I understand now.

From what I understand now, you have the DMZ set up the server that are measured with a public IP address on the real servers. And for those that you have configured NAT0.

Then you have other servers that do not have public IP addresses themselves, but they are translated on the SAA.

If this is the case, then the next question would be. The server with the NAT should attend the L2L VPN connection with their real IP or address IP NAT.

Of course if you configure static NAT for the same servers and NAT0 the NAT0 will always win.

You have these guests who were not able to use the VPN L2L

31.10.10.10 10.17.128.20

31.10.10.11 10.17.128.21

31.10.10.12 10.17.128.22

31.10.10.13 10.17.128.23

IF you want them to go to the VPN L2L with their original IP address then you must configure

object-group, LAN

host of the object-Network 10.17.128.20

host of the object-Network 10.17.128.21

host of the object-Network 10.17.128.22

host of the object-Network 10.17.128.23

object-group, REMOTE network

host of the object-Network 102.1.1.10

inside_nat0_outbound list extended access allowed ip-group of objects LOCAL object-group remote

outside_cryptomap_50 list extended access allowed ip-group of objects LOCAL object-group remote

IF you want to use the L2L VPN with the public IP address, then you must configure

object-group, LAN

host of the object-Network 31.10.10.10

host of the object-Network 31.10.10.11

host of the object-Network 31.10.10.12

host of the object-Network 31.10.10.13

object-group, REMOTE network

host of the object-Network 102.1.1.10

outside_cryptomap_50 list extended access allowed ip-group of objects LOCAL object-group remote

EDIT: in this case you naturally do not configure any NAT0 for actual IP addresses we want precisely the IP addresses to be visible to the L2L VPN with the IP NAT address.

Or you can of course use the same "object-group" as currently but change the content in an appropriate manner

Be sure to mark it as answered if it was answered.

Hello

OK, given the above information, I would say that the VPN L2L your part should probably be fine for traffic you are trying with the packet - trace.

It seems that you get no traffic back from the remote end

This could mean one of the following things
- Remote site may not login either in their VPN appliance, firewall or the firewall of the real server (which I doubt since were talking about web service)
- Remote site has not configured routing properly for your source IP address / network. For example, your connection attempt can reach the remote server, but the return traffic could get transferred to the wrong place on the remote site. It is more likely when the remote end manages Internet traffic and VPN traffic on separate devices
- Remote site has not activated the service on the real server (which is still little provided this isn't a service only serve on the server you through this VPN L2L)
- etc.
As I said look it seems so VPN L2L is fine. Its place and running, but you can't get traffic back on the L2L VPN that suggest that the problem is at the remote site.

If you go ask about this since the admins of the remote site, let us know how to do the thing.

If you found this information useful, please note the answer/answers and naturally ask more if necessary

IPsec site to Site VPN on Wi - Fi router

Hello!

Can someone tell me if there is a router Netgear Wi - Fi that can form IPsec Site to Site VPN connection between 2 Wi - Fi routers via the WAN connection?

I know that this feature exists on the Netgear firewall, but can you have the same function on any Wi - Fi router?

See you soon!

Michael

I suspect that.

Thank you very much for the reply.

See you soon!

Site to site VPN, I need all internet traffic to exit the site.

I have 2 sites connected via a pair of SRX5308

A = 192.168.1.0/24

IP WAN = 1.1.1.1

B = 192.168.2.0/24

IP WAN = 2.2.2.2

Now what I need to do, is to have all traffic from B to go to the site one even traffic destined to the internet. That is, I need internet traffic out of our network with the IP 1.1.1.1, even if it is from the network B.

On my I have set up a route 1.1.1.1 of the ISP, then a value by default 0/0 to 192.168.1.1 it ASA knows how to get to the peer VPN is a more specific route, but sends everything above the tunnel, at the remote end which then hairpin of ASA routes internet outside its own WAN port traffic.

I can understand though not how to so the same thing on the pair of SRX5308 they either don't raise the tunnel or internet route to the local site address B.

Anyone have any ideas?

I need to do this because we are logging and monitoring of internet traffic to A site via tapping from upstream to various IDS solutions and will not (cannot) reproduce this to all our remote sites.

Thank you

Dave.

After some more thought and testing I came up with a workable solution to my own problem. I'll share it here in case it can help others.

(1) use the wizard at both ends to implement a normal VPN that connects the two segments of network 192.168.1.0 and 192.168.2.0

(2) go to site VPN - VPN policy remote router192.168.2.1 and click Edit

(a) disable Netbios

(b) select "None" from the drop-down list the remote IP address.

(c) to apply the change

3) go to the VPN-> VPN policy on the head end site (192.168.1.1) and click Edit

(a) disable Netbios

(b) select "None" from the drop-down list the local IP address

(c) to apply the change

Now all the traffic wil go down the VPN tunnel and exit to the internet on the site of head end. Hope this helps others with the same question.

Site to Site VPN on AZURE

I have a VPN site-to-site existing on Azure and Azure a new subnet created on the local network that must be able to reach.

I added the new subnet within azure for the VPN and add a static route on the RRAS server win 2012 for routing.

On the initial installation of a RRAS-Site VPN site (I didn't configure it) I think the interesting traffic specified must be sent through the VPN Tunnel, but I knew how to specify the new subnet via RRAS, I don't want to delete and re-create the VPN Site to Site.

Y at - there anyone who can help please.

Thank you

Philippe

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.
