Several VPN

Hello

My network is this way:

ASA1 (7.2.2)

INTERNET = (6.3.5) PIX

ASA2 (7.2.2)

I'd like to ASA1 accesses ASA2 and PIX network

So I would ASA2 can access network of PIX via ASA1 and ASA1 network

And finally, I would like that PIX can access ASA2 network via ASA1 and ASA1 network

Is it possible to do?

Thank you

Yes, it is possible to pin the traffic on the external interfaces of the SAA for traffic in tunnels is the pix.

You must enable permit same-security-traffic intra-interface. You must also add traffic to your ACL crypto and nat exemption (only if running off nat). Here is a good doc with an example... Here are the PIX, but the config in the pix of the 7 version is pretty much the same.

Several VPN strategies to even peer. Is is possible?

I am trying to create several strategies of VPN for the peer even on a TZ 105. The peer is an another SonicWall. Whenever I have create the second strategy the peer starts sending invalid ID back messages in IKE1 negotiations.

The two policies are using sources different subnets and subnets of different destination. A source subnet is connected to the X 0 port and the other to port X 2. The basic idea is for devices on the subnet connected to the X 0 port to reach a limited number of private behind the SonicWall remote subnets. Devices connect to port X 2 should tunnel all public internet traffic over the VPN and access the internet through the SonicWall remote. There are complicated reasons behind this desired configuration.

I am new to SonicWall, so I don't know if it is still possible to what I'm trying to do. If this is the case, I am clearly something wrong. I'll fill in more details if necessary.

No you can't do that. You must create 1 policy that contains all the networks you want to allow to browse this VPN.

Several VPN site to site on the same ASA

I need to set up an IPSEC tunnel to allow a provider to the remote site printing to a printer on my network. I intend to use an ASA 5520 to do this. The architecture is fairly simple:

[Remote]-[Remote FW] --[FW Local]-[Local routing]-[printer]

The downside is that there is finally more than a seller who needs to do. Each will have a different destination but mena there will be more than a VPN to ASA at my end. It seems that the ASA 5520 can be supported more than a VPN site to site, but I need to assign an IP address for different endpoint in each tunnel?

I searched and found no a design guide for the VPN site - to-many. If so, I'd appreciate a pointer.

You can do several tunnels VPN site to site. As a general rule, you would have a card encryption applied to the interface in the face of internet. Each crypto map entry has a sequence number. You simply have to create all the necessary configurations (tunnel-group for the remote peer IP, ACL to set interesting traffic, etc.) and increment the entry card crypto.
```
 Example: crypto map outside_map 1 match address s2s-VPN-1 crypto map outside_map 1 set pfs crypto map outside_map 1 set peer 1.2.3.4 crypto map outside_map 1 set transform-set ESP-3DES-SHA tunnel-group 1.2.3.4 type ipsec-l2l tunnel-group 1.2.3.4 ipsec-attributes  ikev1 pre-shared-key SomeSecureKey$ crypto map outside_map 2 match address s2s-VPN-2 crypto map outside_map 2 set pfs crypto map outside_map 2 set peer 4.5.6.7 crypto map outside_map 2 set transform-set ESP-3DES-SHA tunnel-group 4.5.6.7 type ipsec-l2l tunnel-group 4.5.6.7 ipsec-attributes ikev1 pre-shared-key SomeSecureKey2$

Several VPN GET with Multicast clouds

Hi all

It is a recommended approach to use different multicast addresses if you use a key server to manage several groups GET VPN? It is not a provider environment hosted service but just for one customer in need of a logical separation.

I think it would be a good idea to do it, but I'm not very familiar with multicasting on a set, so I would appreciate anyone sharing similar experiences or the potential pitfalls with this config. Is there something I need to watch out for?

Xavier

Xavier,

given that we can separate the information at the level of the GDOI groups you should not need to use multiple addresses.

However consider a scenario in which a GM is part of Group 1, but not in Group 2. He will receive discount at the key for both, but will not be able to understand group2 generate a new key, you will see the log messages that signals a problem once per hour.

It makes sense to separate the addresses mcast especially if this deployment could grow/fork/expand in the future.

ASA 5505 - several VPN subnet

I'm trying to set up a VPN for use with the Cisco VPN Client. I currently have operational VPN, but I cannot allow access to several subnets connected to the ASA. My current stock of VPN DHCP is 10.0.0.0/24. I want to VPN users to talk to one of my other VLAN (172.16.20.0/24). That's what I can't understand. If I change my VPN DHCP pool to something like 172.16.20.100 - 110 can I talk to about everything on this fine subnet. But as soon as I change the DHCP pool to the other subnet so I can't. Any suggestions?

Here is my config:

Several VPN clients behind PIX

Multiple users in our company have establish a VPN client connection to a VPN Internet gateway. The connection must go through our PIX. I already active correction for esp - ike Protocol and this allows a user to get out. When following users try to configure a VPN connection to the VPN gateway on the internet, the following syslog error appears:

3 PIX-305006%: failed to create translation portmap for udp src inside:192.168.0.102/500 dst outside:1x5.x17.x54.x10/500

It seems to me that the PIX only supports an outbound VPN client connection at the time. Is this true?

When I perform a clear xlate, first user disconnects, but new users is able to establish a VPN connection.

Kind regards

Tom

That's right, Tom - in the release notes for 6.3 (1), the PAT for ESP section says "PIX Firewall version 6.3 provides protocol PAT IP 50 capacity to support unique outbound IPSec user."

If you have enough public IP addresses and the remote VPN gateway supports PPTP, then a means to achieve multiple outbound VPN connections would be to set up a separate pool of the NAT for users who require outbound access and assign internal IP addresses of those users to use these addresses.

Having had just a quick look around, if PPTP is an option, then the PPTP PAT 6.3 support can help.

Several VPN Client 1 LAN

Hello

We have 2 users who need to connect to our PIX 515 6.1 (4) using the client software of Cisco VPN Client 4.0.5 (Rel) on the Remote LAN Site.

they all have access to the Internet Via Watchguard Firebox and router Cisco 1712.

, but only one can access our VPN through the Cisco VPN client at the same time. When the 2nd user try to connect, the other connection of users disconnects.

Does anyone have a question?

How to create several site VPN on Cisco 2801

Hello

We use 2801 to our VPN needs. We have already configured a VPN site-to site inside. My current scenario is to create several VPN IE at different sites and a remote client VPN server for our road warriors (they use a cisco VPN client to connect).

Let me know how can I achieve that scenario. Currently we have in VPN profiling in place. can I fill the script using VPN profiles, how it can be used. Kindly advice me at the earliest.

Please find attached the 2801 direct configuration file, which is quite works very well

Thanks in advance.

As much as I know it does no harm to have political isakmp 9 and isakmp 10 with the same parameters in each of them. But it also is not good. Others that extra isakmp policy I don't see anything that seems problematic in the config you have posted.

Troubleshooting IPSec Site to Site VPN between ASA and 1841

Hi all

in the past I've implemented several VPN connections between the devices of the SAA. So I thought a site link between an ASA site and 1841 would be easier... But it seems I was mistaken.

I configured a VPN Site to Site, as it has been described in the Document ID: SDM 110198: IPsec Site to Site VPN between ASA/PIX and an example of IOS Router Configuration (I have not used SDM but CCP).

I have run the wizards on the ASA with ASDM and the current IOS version 15.1 1841, with CCP.

It seems to Phase 1 and 2 are coming although my ASA in ADSM reports (monitoring > VPN > VPN statistics > Sessions) a tunnel established with some of the Tx traffic but 0 Rx traffic),

It seems that the routing on the 1841 is working properly as I can tear down the tunnel and relaunch in scathing a host on the network of 1841, but not vice versa.

Trounleshoot VPN of the 1841 report shows a message like "the following sources are forwarded through the interface card crypto. (172.20.2.0 1) go to "Configure-> routing" and correct the routing table.

I have not found an error on the 1841 config so if one of the guys reading this thread has an idea I appreciate highly suspicion!

It's the running of the 1841 configuration

Joerg,

ASA receives not all VPN packages because IOS does not send anything.

Try to send packets to the 1841 LAN to LAN of the ASA and see is the "sh cry ips its" on the 1841 increments the encrypted packets (there not)

The problem seems so on the side of the router.

I think that is a routing problem, but you only have one default gateway (no other channels on the router).

The ACL 100 is set to encrypt the traffic between the two subnets.

It seems that the ACL 101 is also bypassing NAT for VPN traffic.

Follow these steps:

Try running traffic of LAN router inside IP (source of ping 192.168.37.x 172.20.2.254) and see if the packages are not through the translation and obtaining encrypted.

I would also like to delete 100 ACL from the inside interface on the router because it is used for the VPN. You can create an another ACL to apply to the interface.

Federico.

The VPN Site - to-many with PIX 6.3 (5) Can you do?

Hello

I set up a VPN tunnel between two PIX (for example, A PIX and PIX B) running 6.3 (5). It works very well. I then tried to add another VPN to PIX A tunnel to a new PIX C. It does not work! It seems that I can only assign a card encryption, and therefore a tunnel, in a phyical interface on the PIX. Is this good? I assumed that you can run several VPN tunnels since a single physical interface.

All advice warmly received!

Concerning

Paul

You can use something like this

map VPN-map 10 ipsec-isakmp crypto

VPN - 10 card crypto card matches the address B - VPN

card crypto VPN-map 10 set peer b.b.b.b

card crypto VPN-map 10 the transform-set ESP-AES256-MD5 value

card crypto VPN - ipsec-isakmp 20

VPN - card 20 crypto card matches the address C - VPN

card crypto VPN-card 20 set peer c.c.c.c

card crypto VPN-card 20 the transform-set ESP-AES256-MD5 value

Parallel VPN tunnel

Hi guys,.

We have several VPN site to site tunnels that is currently working. We intend to change the IP addresses for all of our internal subnets and I wonder if we can create VPN tunnels parallel at the same time with the new IP addresses? (I think this is only about the access lists). If it works, then I can go and remove the old tunnels when everything is done. Any help will be greatly appreciated.

Thank you

Lake

You can create parallel tunnels only if the below are different:

1. address of the remote peer

2 source/destination in the ACL encryption

Router VPN site-to-site recommendations

Hello

I have to configure a VPN tunnel between the main and branch offices of a (very) small business. Is there a broadband internet access in both sites through cablemodems ethernet. ISPS assign the two dynamic cablemodems IP addresses public, which means that they are accessible from anywhere.
In fact, it is a very simple task. My question is:

What is best Linksys/Cisco equipment for this configuration of small businesses, as both routers should have in addition to the functionality of server VPN wireless capabilities?

I thought to of the Linksys WRTxxxN, but they don't VPN (they are public devices in any case). Then I thought of the RV042 appreciated, but there is no wireless unfortunately.

I'll highly appreciate recommendations. Remember that routers are for a very small company, so they should be prices accordingly.

Thanks in advance,
Fernando Ronci

Cisco Small Business has several VPN wireless routers, that supports site to site VPN.

WRV210 and WRVS4400N are older models, while R120W and RV220W are of newer models. You can find pricing information on the sites of e-commerce as CEP, newegg, amazon or buy.com.

If you have the double condition of WAN, for example, the increased reliability of internet connectivity, adding a point of access (for example WAP4410N) wireless R042 might be a good choice.
