Remote VPN using Site 2 Site VPN

Hi all

I have 2 ASA 5505 firewall, VPN of Site 2 Site working between two firewalls. I have attached the visio diagram for my senario. I configured remote IPsec VPN in the firewall of the ASA-01, a capable user of connted to ASA-01 network via remote modem via VPN. As I set it up 2 a VPN between two ASA site, is possible only through remote VPN, a user can connect to ASA - 02.

Thank you

3 things. You must allow traffic to enter/exit the same interface to ASA - 01

permit same-security-traffic intra-interface

You must then add the new traffic lights to the existing acl for the lan to lan vpn. If ASA-02 network 192.168.2.0/24 and vpn client network 192.168.10.0/24 it would look like this.

ASA-01

access-list extended xxx permit ip 192.168.10.0 255.255.255.0 192.168.2.0 255.255.255.0

ASA-02

xxx list extended access permit ip 192.168.2.0 255.255.255.0 192.168.10.0 255.255.255.0

and also the nat 0 ASA-02

nat0 list extended access permit ip 192.168.2.0 255.255.255.0 192.168.10.0 255.255.255.0

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.

Concerning

Remote VPN users cannot access tunnel from site to site

Cisco ASA5505.

I have a tunnel of site-to-site set up from our office to our Amazon AWS VPC. I'm not a network engineer and have spent way too much time just to get to this point.

It works very well since within the office, but users remote VPN can not access the tunnel from site to site. All other remote access looks very good.

The current configuration is here: https://gist.github.com/pmac72/f483ea8c7c8c8c254626

Any help or advice would be greatly appreciated. It is probably super simple for someone who knows what they're doing to see the question.

Hi Paul.

Looking at your configuration:

Remote access:

internal RA_GROUP group policy
RA_GROUP group policy attributes
value of server DNS 8.8.8.8 8.8.4.4
Protocol-tunnel-VPN IPSec
value of Split-tunnel-network-list Split_Tunnel_List

permit same-security-traffic intra-interface

type tunnel-group RA_GROUP remote access
attributes global-tunnel-group RA_GROUP
address RA_VPN_POOL pool
Group Policy - by default-RA_GROUP
IPSec-attributes tunnel-group RA_GROUP
pre-shared key *.

local pool RA_VPN_POOL 10.0.0.10 - 255.255.255.0 IP 10.0.0.50 mask

Site to site:
```
  
```
card crypto outside_map 1 match address acl-amzn

card crypto outside_map 1 set pfs

peer set card crypto outside_map 1 AWS_TUNNEL_1_IP AWS_TUNNEL_2_IP

card crypto outside_map 1 set of transformation transformation-amzn

I recommend you to use a local IP address pool with a different IP address that deals with the inside interface uses, now you are missing NAT are removed from the IP local pool to the destination of the site to site:

NAT_EXEMPT list of ip 10.0.0.0 access allow 255.255.255.0 172.17.0.0 255.255.0.0

NAT (outside) 0-list of access NAT_EXEMPT

Now, there's a dynamically a NAT exempt allowing traffic to go out and are not translated.

I would like to know how it works!

Please don't forget to rate and score as correct the helpful post!

David Castro,

You try to run a Site to site VPN and remote VPN from the same IP remotely

We currently have a site to site VPN configuration between our offices call center and a 3rd party that allows them to access our training to their employees to use environment while being trained on our systems. This tunnel is running between our ASA and their ASA without problem; However, when we have managers come out to the call center, they are unable to use remote VPN to access our office.

Apparently the same IP peer remote that we use for our site to the other tunnel is the same IP that our managers use to access the internet when they are on-site with the customer. When I look at the logs it shows the VPN attempt and then I get treatment Information Exchange has failed. So from what I can understand when our managers are trying to connect to our firewall from the same IP address as the counterpart of site to site it automatically tries to create a tunnel, according to the information of the site to the other tunnel. If our managers are anywhere else, they can connect through remote VPN with no problems.

My question is if anyone knows of a way to make the firewall allow VPN site to site and remote connections with the same remote IP address.

Hi John,.

Basically, in older versions, when you hit a static encryption card and you does not match this static encryption completely map the connection continues until the dynamic encryption card. For this reason, you can connect your IPSec clients before. A bug has been opened on this vulnerability.

CSCuc75090 Details of bug

The crypto IPSec Security Association are created by dynamic crypto map to static peers

Symptom:

When a static VPN peer adds all traffic to the ACL crypto, a surveillance society is based even if the pair IP is not allowed in the acl to the main façade encryption. Are these SA finally put in correspondence and commissioning the dynamic crypto map instance.

Conditions:

It was a planned design since the first day that allowed customers to fall through in the case of static crypto map did not provide a necessary cryptographic services.

The SA must be made from a peer configured statically and a dynamic crypto map instance must be configured on the receiving end.

Workaround solution:

N/A

Some possible workarounds are:

Configure a static nat device when you try to use the remote VPN if the firewall remotely will be hit with a different public IP address. It would be a good solution, but it will depend on how many ip addresses public you have available, if you really want one of these ip addresses for that access.

Also, I thought you could use AnyConnect instead of the IPSec VPN client. I don't know how many users need to connect from your PC to the remote site, but the ASA has 2 licenses SSL available that you could use. Because Anyconnect uses the SSL protocol, it won't have a problem on your environment.

Below some information:

http://www.Cisco.com/c/en/us/TD/docs/security/ASA/asa84/configuration/guide/asa_84_cli_config/vpn_anyconnect.html

Hope this helps,

Luis.

Breeze remote VPN VPN site-to-site

Excuse me, but I am a novice with this and in over my head.

I'm trying to add features to remote VPN to a small office ASA5505 that works well for external access to the ' net and has a tunnel from site to site in an office in another city.

After the various guides, I have added (or tried to add) the necessary configuration, but when I try to add cryptographic declarations for the remote vpn, VPN site-to-site goes down. The internal network is on 10.1.10.0/24 and remote users must be on the 192.168.30.0/24 subnet

I would appreciate anyone pointing out some stupid mistake that I made. Here is the configuration of private information and outside addresses "cleaned."

Thanks in advance for your suggestions!

Remote VPN site to site vpn on ASA?

Hello

I would like to know if it is possible to have this configuration with an ASA5510:

(1) - remote access VPN (access by the external interface)

(2) - site to site VPN (same access interface)

The goal: users of vpn (1) can access the server remote vpn (2) and vice versa.

Is it possible? and what is the best practice to do?

Thank you very much!

J.

Yes, you can do it.

Same-security-traffic command traffic to enter and leave the interface even when used with the

keyword intra-interface, that allows the VPN support has spoke-to-spoke.

Here are a few examples.

Tunnel remote VPN Site to Site

Hello

I am facing a problem with my remote VPN users, I describe my network here. I have a site to another tunnel for my USA, tht IP 169.X.X.X. office client, we are able to connect this tunnel. now I configured remote vpn for users of my home, my office inside the IP is 192.168.2.X and once I connect to home, in the office through vpn cisco client, then, my ip is 192.168.3.X I put the IP in ASA pool, now 192.168.3.X and 192.168.2.X communicates correctly , but I need to access my Tunnel IP 169.1.X.X also from 192.168.3.X (Home).

203.92.X.X is my static public Ip address that is allowed in the client side for the tunnel.

If something confussing please let me know.

Thank you

Nitin

Nitin,

It is not possible to have a NATing on 192.168.3.0/24 to public ip address because it has default route (which you can reach L2L remote host) on the SAA pointing to the external interface. This default route will be redirect/road traffic on the external interface only vpn client so NATing will reach us.

Please note that the configuration is incomplete, I added that relevant changes, you should bring to the allow clients of RA through the LAN-to-LAN tunnel, of course, the LAN-to-LAN settings should match to the other side of the tunnel that is mirror of ACL, NAT and so on.

Routing of a VPN from Site to site to remote VPN users

Hello

We have a site and remote vpn site configured in the same interface in ASA 5520 (software version 8.3). When the remote vpn users try to connect to the computers located at the far end of the site to site VPN, their request has failed. I tried No.-Nat between remote vpn IP private to the private IP address of remote site, also said the same split tunneling. I can't find even the tracert, ping has also expired.

Is there any solution to make this live thing.

Shankar.

There are a few things that need to be added to make it work:

(1) on the SAA where remote vpn users connect to, you must add "permit same-security-traffic intra-interface"

(2) you mention that you have added the LAN of remote site-to-site in the list of split tunnel, so that's good.

(3) on the SAA ending the vpn for remote access, you must also add the following text:

-Crypto ACL for the site to site VPN must include the following:

permit ip access list

(4) on the ASA site to remote site, you must add:

-Crypto ACL for the site to site VPN must include the following:

permit ip access list

-No - Nat: ip access list allow

Remote VPN cannot ping any host on remote site

Hi all!

I tried to deploy remote vpn on my asa 5515-x. And my VPN client properly connected, but I can't ping any host on a remote network.

Here is my configuration:

Hello

I would like to change the current reserve of VPN to something overlapping to the LAN.

You're also missing NAT0 for the VPN Client connection that is your problem more likely.

You can try these changes

You can also change your settings for encryption for anything other than a. You can use AES.

Hope this helps

Cannot access remote VPN site-to-site VPN

Internal network: 192.168.0.0/16

The remote VPN Clients: 192.168.0.100 - 192.168.0.254

Remote (L2L) network: 10.10.10.0/26

Remote VPN Clients are able to access the internal network without problem, but are unable to access the remote 10.10.10.0. Is it possible to debug this? "packet - trace" show no problem...

Hi Ben,

Please create a no. - nat on the external interface, because your customers to vpn-remote and remote-L2L tunnels are located on outside interface (i.e. from the outside). You should treat your outside network identical to your inside network, as you would create a no. - nat for your inside networks.

The ACL you create for the no - nat outside must be in both directions as below.

permit access ip 192.168.0.0 scope list outside_nat0 255.255.255.0 10.10.10.0 255.255.255.192

outside_nat0 to access extended list ip 10.10.10.0 allow 255.255.255.192 192.168.0.0 255.255.255.0

NAT (outside) 0-list of access outside_nat0

permit same-security-traffic intra-interface

Pls let me know, if this is useful.

Thank you

Remote VPN users cannot reach OSPF Inter networks

Hi all

Area0 & Grenier1. Grenier1 ASA has remote VPN configuration where users also use split tunneling. When the VPN plug-in users, accessing all respurces successfully in the area euro1, but unable to reach Area0 resources.

But Area0 PCs can 'ping' on addresses IP VPN component software plug-in. I tried 'debug icmp trace', but not poping up even one message upwards all to initiate the 'ping' of the computer laptop VPN users.

FYI... Grenier1 N/w: 10.251.0.0/16 and 10.251.40.0/24 has been used for VPN DHCP users. Everything works well except for the Area0 accessibility.

Any suggestions... ?

Thank you

ASA Version 9.0 (1) - Ping works both inside and outside, WWW does not work for remote VPN

I am at a loss, I can connect VIA VPN and Ping inside the IPs (192.168.1.2) and outside (4.2.2.2) IPs of the remote VPN client, but can't surf WWW. Inside the network, all users have WWW access and the network is fine. I'm new on the revisions to ver 8.3 and don't see what I'm missing?

Hello

Its propably because you do not have a DNS server configured for VPN users. Try this command:
```
 group-policy DfltGrpPolicy attributes dns-server value 8.8.8.8
```

Reverse road injection for remote VPN Clients

Hello world

you will need to confirm if reverse road injection is used only for Site to site VPN?

Also to say that we have two sites using site-to-site vpn

Site A Site B

Private private IP IP

172.16.x.x 172.20.x.x

Now, as we VPN site to site, we can either activate the NAT - T option which will allow 172.16 IP reach site B as 172.16 only.

Do not change the IP address.

Option 2

IF we don't allow NAT - T and if we allow injection road Revese and we use say Protocol ospf on ASAs in site A and B.

In this case, we allow IPPS so that we can announce the private road 172.16. on the internet right of site B?

Concerning

MAhesh

Hello Mahesh,

"Reverse road injection (RRI) is used to fill in the routing table of an internal router that is running OSPF Open Shortest Path First () protocol or the RIP (Routing Information) protocol for Remote Clients VPN sessions or a local area network LAN."

Source: http://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-next-generation-firewalls/107596-asa-reverseroute.html

As a result, allowed RRI ASA learn routing information for connected peers and advertising via RIP or OSPF.

NAT - T is automatically detected and used when the local or the remote peer is behind NAT.

To answer your question:

If NAT - T is required and enabled, then it will automatically be used peer VPN. Then, with IPP in place, remote network will be added to the routing as static routes table, so they can be advertised by OSPF.

HTH.
