ASA SITE VPN 55XX survey?

Hi all

I was wondering if I have a Cisco ASA firewall and there several site to site VPN using pre-shared keys. If I want to add an another VPN Firewall. Do I have to add all the crypto ISAKMP stuff yet or what. Or I can just all ready config VPN in the firewall. I mean besides the new card Crypto, ACLs and the NAT 0 statement that other statements do I need to enter this new site to the other tunnel in the buld order? I don't want to end up ordering more than is necessary.

No, you don't need to add new isakmp crypto policies if you already have a configured strategies match. You can also reuse the crypto ipsec transform-set political if it is the same on the other site of the LAN-to-LAN tunnel (as long as it matches at both ends).

You're right, the only statements, you need to add would be the ACL for NAT entry 0 and new sequence card crypto (with crypto ACL, all processing and input of game peer).

Hope that helps.

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),

On the ASA:

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.

VPN site to site & outdoor on ASA 5520 VPN client

Hi, I'm jonathan rivero.

I have an ASA 5520 Version 8.0 (2), I configured the site-to-site VPN and works very well, in the other device, I configured the VPN Client for remote users and works very well, but I try to cofigure 2 VPNs on ASA 5520 on the same outside interface and I have the line "outside_map interface card crypto outdoors (for VPN client). , but when I set up the "crypto map VPNL2L outside interface, it replaces the command', and so I can have only a single connection.

the executed show.

"" I thing both the force of the SAA with the new road outside, why is that? ".

without the road ASA pushes traffic inward, by default.

In any case, this must have been a learning experience.

Hopefully, this has been no help.

Please rate, all the helful post.

Thank you

Unable to pass traffic between ASA Site to Site VPN Tunnel

Hello

I have problems passing traffic between two ASA firewall. The VPN tunnel is up with a dynamic IP and static IP address. I have attached a diagram of the VPN connection. I'm not sure where the problem lies and what to check next. I think I have all the roads and in the access lists are needed.

I've also attached the ASA5505 config and the ASA5510.

This is the first time that I've set up a VPN connection any guidance would be greatly appreciated.

Thank you

Adam

Hello

Regarding your opinion of configuration Remote Site ASA that you have not added the internal networks of the Central Site VPN L2L configurations at all so the traffic does not pass through the VPN.

Take a look at ACL configurations above. The 'exempt' ACL is used in configurations NAT0 and tells the ASA what traffic of exempting from NAT. "outside_1_cryptomap" ACL is used to tell the traffic between the subnets should be using the L2L VPN connection.

So in short on the Remote Site ASA these ACLs should be identical. Make additions to the LIST of VPN L2L, then try again.

I would also like to point out that to ensure that the Central ASAs L2L VPN ACL Site contains the same networks. The ACL on the Central Site will, of course, its internal subnets as the source and the site LAN remote destination.

THW out of ' crypto ipsec to show his " shows you that only the SA between binding Site Central network and the Remote Site LAN was established. Others have not formed as the configuration is lacking at LEAST on the Remote Site ASA. Can also be the Central Site.

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

Site to Site VPN working without Crypto Card (ASA 8.2 (1))

Hi all

Find a strange situation on our firewall to ASA5540:

We have a few Site to Site VPN and also activate on the ASA VPN cleint, all are working properly. But finding that a VPN from Site to Site is running without crypto map configuration. Is this possible?

I tried to erase isa his and claire ipsec his then VPN came once again. Tested too, it's the ping requests to a remote site through the VPN.

I saw there are config tunnel-group for VPN but saw no card crypto and ACL.

How is the firewall knows what traffic should be encrypted for this VPN tunnel without crypto card?

This is the bug?

Thanks in advance,

It can be an easy vpn configuration.

Could you post output config operation remove any sensitive information. This could help us answer your question more specifically.

Order of operations NAT on Site to Site VPN Cisco ASA

Hello

I have a question about the order of operations NAT on Site to Site VPN Cisco ASA 8.2.x. I have a scenario where the internal IP address of the range 10.17.128.x are NATTED IP public 31.10.10.x. below is the config:

Tunnel normally passes traffic to dmz - 31.10.11.10, 31.10.11.11 servers.

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

Also, if you could tell me the order of operations to NAT via VPN Site to Site, it would be useful.

Thank you

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

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

ASA 5505 VPN Site to site with several networks

Hello

I have a Cisco ASA 5505 configuration problem and hope you can help me.

Our company created a second facility, which must be connected using VPN to our headquarters.

I used the ASDM "Wizard of Site to site VPN" to create a connection, which works very well with our main network.

Following structure:

Headquarters:

Cisco ASA 5505, firmware 9.1, ASDM version 7.1

Outside: Fixed IP

Inside: IP address of the interface is 192.168.0.1/24 (data network)

Now I have a second network 192.168.1.0/24 (VoIP network), PBX address is 192.168.1.10.

The two networks should be accessible through the VPN.

New installation:

Cisco ASA 5505, firmware 9.1, ASDM version 7.1

Outside: Fixed IP

Inside: IP address of the interface is 192.168.2.1/24

I have already created a connection until a PC of the new plant reaches the data network. For example, a ping from 192.168.2.100 to 192.168.0.100 is possible.

Now, I want to add some VoIP phones to the new facility, which can reach the PBX on 192.168.1.10.

In the link, I have already added the two networks as remote network:
```
object-group network Testgroup network-object 192.168.0.0 255.255.255.0 network-object 192.168.1.0 255.255.255.0 access-list outside_cryptomap extended permit ip object-group Testgroup object Remote-Network 
```
My problem now is, I don't know what to define as 'Bridge' on my PBX.

I can't use 192.168.0.1 because it's a different subnet. Also, I can not put a second IP 192.168.1.1 to the interface of the ASA.

You have any ideas, how can I accomplish this, so that the two subnets are accessed through the VPN and all devices have a defined gateway?

Could a "Easy VPN Remote" in "Network Mode" you help me?

What is the difference between 'Site-to-site' and 'extended network '?

Kind regards

Daniel condition, look for the solution GmbH

You can optionally configure a new LAN VIRTUAL (VLAN PBX) on the SAA and connect this interface to the voice network.

If you do not have a spare on the ASA port, then Yes, you have a router to route traffic from the PBX to the ASA via the data network.

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.

Site to Site VPN ASA 5510

OK my forehead is painful to all keyboard strokes that I know that it must be something simple, but I am brand new to the SAA. I had a site to site VPN configuration via routers 1751 that worked very well, but we're looking to add some more remote field offices, and I felt that it would be easier to maintain several sites is on the ASA 5510. I have the VPN configured on the SAA and he said that the tunnel is up. I can telnet to the ASA and ping the remote gateway on the even side of VPN and it pings fine. If I try to ping on a local computer, I get a "Request timed out". If I makes no changes apart from go to the computer room and replace the network cable the 1751 and then through the 1751 I can now ping the remote door way to my computer. The remote router works obviously very well, my statement of route on my router for vpn push through the ASA (same ip address) IP traffic that has been used by the 1751 works obviously. It seems so just like ASA is not being pushed in the ethernet0/0 VPN traffic or at least it is not encrypted. I also noticed that the ACL for NAT seems to increase in number of access either it seems, there is really just one small thing missing to make the ASA except and encrypt incoming traffic on ethernet0/0:

My network is not configured with a DMZ is something like that, the ASA ethernet0/0 and my local network on the same subnet:

Router (Cisco 2811)

Layer switch 2 (ProCurve)

ASA5510 LAN computers

I'm trying to except both sides of the VPN in and out on Ethernet0/0 traffic I saw there was a framework for this "permit communication between VPN peers connected to the same interface' and I've activated this option.

In short, I need to understand why the VPN tunnel shows that upward and I can ping the remote of the SAA, but peripheral gateway on my network can not ping to the remote gateway through the int Ethernet0/0 on the SAA.

From the console of the ASA, I get this:

ASA5510 # ping 192.52.128.1

I haven't added anything to the config except what seemed necessary to get the job of VPN tunnel. It should be fairly clean.

Thanks in advance for any help... I really hope that it is something really simple as a recruit ASA just forgot

Strange, but good news. Thanks for the update. I'm glad everything is working.

Cisco ASA 5510 VPN Site to Site with Sonicwall

I am trying to configure a tunnel between a Cisco ASA 5510 VPN (Version 8.2 (2)) and TZ200 Sonicwall. I rose tunnel and go and I am able to ping the internal IP address of Cisco ASA of the Sonicwall LAN but nothing work. When I try to ping a host behind the Cisco ASA of the Sonicwall LAN I get the following message "rules asymmetrical NAT matched for flows forward and backward; Connection for tcp src outside:10.20.10.x/xxxx dst inside:10.20.2.x/xxxx refused due to failure of reverse path of NAT"on the SAA

Googling the error above shows the problems with version 8.3 or later that resembled the nat commands have been changed SAA, train is still on 8.2 but I another common question does not add an exemption of NAT I have double-triple checked that I did add an exception rule of NAT of the hosts on the network from cisco for the guests of the Sonicwall network. Looks like I hit a road block so any help would be appreciated. Thank you

Here are a few excertps of the config file (10.20.2.0 behind the cisco) and 10.20.10.0 behind the sonicwall

Hello Manjitriat,

Okay, detected IPSEC parody is normal, that means you are trying to send unencrypted on a line of encrypted packets.

Now, if you see on the plotter of package that traffic will hollow the VPN channel all its fine in your site.

Now the packet tracer must be something like this:

entrance to Packet-trace inside private_ip_lan destination_private_ip_lan 1025 tcp 80

Please provide us with the result of the following instructions after you run the packet tracer.

Route inside 10.1.1.0 255.255.255.0 172.10.1.1 - road join the ASA-SiteA-inside interface

Inside the two ASAs interfaces can communicate with each other through circuits MPLS. We want to create a VPN tunnel between two DMZ networks so that traffic passes through a tunnel through the local network. You can check the config below and indicate if any changes are needed.

1 tunnel VPN to work, not the traffic must match a route on the ASA or simply to match the access-list(interesting traffic) for example after the configuration of the VPN tunnel between 192.168.0.0 and 192.168.87.0 networks when I ping 192.168.87.1 route IP made it reveal the tunnel because it fits to the interesting traffic or packets go to 4,5,6,7 where they correspond to the default?

2. virtue normal Site VPN to Site traffic scenarios run on high security interface (DMZ or inside) and goes to the interface (outside) low security, but in the case above traffic intiates on low security interface (DMZ) and goes to the high safety (inside) interface which usually gets blocked unless there is an access list entry to allow that traffic. We must therefore have an IP address a whole (on the access list applied to UI in DMZ) entered between the two dmz networks

Yes, you need the correct route otherwise it will be just forwarded through the default gateway.

So, on A Site, you should have:

Route inside 192.168.87.0 255.255.255.0 10.1.1.x--> x should be the next jump of the SAA within the interface

On Site B, you should have:

Route inside 192.168.0.0 255.255.255.0 172.10.1.x--> x should be the next jump of the SAA within the interface

Delete "transport mode" of two ASA.

To answer your questions:

1. Yes, it would be necessary to match a route, otherwise it will be routed through the default gateway.

2. Yes, you must have access-list to allow high traffic of low level of security. If you want a full IP access, you can configure IP allowed between 2 LANs.

asa himself through site to site vpn access server

Hello

I have problem with access to the servers through site to site vpn to ASA that makes this vpn site-to-site and Clientless VPN enablerd.

Reason why I need it / what I do:

ASA 5510 enabled Clientless VPN and on this Portal allows users to access internal servers through bookmars URL. We use it when someone wouldn't access IPSec VPN or in an internet café. If this user connects to clientless vpn and click on the bookmark to access for example mail server. But there is problem, asa cannot access this server through VPN site-to-site.

Network:

Here's a quick design of my network.

I don't have server access to the problem in the VLAN 159 of VLAN 10, or 100. But I need to be able to access the server in Vlan 159 of ASA 5510, who owns the IP 192.168.1.4.

I have this subnet ASA owned by FRONT-NAT object in the same place that VLAN 10 to 100 are and vpn Site-to-Site profile.

What I makeover or how can I solve it?

Thank you

Clientless VPN when accessing internal servers, it will use the closest to the source of the connection interface and if you connect to via clientless SSL VPN ASA5510 and need access ASA5505 LAN via the site to site VPN, the interface closest to the ASA5510 to ASA5505 LAN is ASA5510 outside interface, therefore, the vpn of site-to-site crypto ACL must match on ASA5510 outside the ip address of the interface.

Here's what you need on each ASA:

ASA5510:

permit same-security-traffic intra-interface

ip 192.168.159.0 external interface allowed access list 255.255.255.0

ASA5505:

ip 192.168.159.0 access list allow 255.255.255.0 host

In addition, also need to add the same ACL for access-list of exemptions on ASA5505 NAT:

ip 192.168.159.0 access list allow 255.255.255.0 host

Hope that helps.

Problems with site-to-site vpn with of the asa 2

I tried different ways so that this works, but failed. After 8 hours, I literally have a bad headache and have to step away for a minute. I realize I need to ping between the tunnels mentioned, but still can not to. can someone take a look and tell me where I have gone wrong? Im trying to configure a site to site vpn between:

ASA_A

external interface 5.179.17.66

inside the interface 10.1.1.1

ASA B

external interface 5.81.57.19

inside the 10.1.2.1 interface

Frist why do you have two DGs on box -

Route outside 0.0.0.0 0.0.0.0 5.179.121.65 1

Route outside 0.0.0.0 0.0.0.0 5.179.17.65 1

Attach the two end then it should work.

Thank you
