Cisco ASA l2l VPN disorder
Hello Experts from Cisco,
I run in trouble with one of my l2l ipec vpn between an asa 5510 and 5520 cisco running version 8.2.2.
Our existing l2l VPN are connected fine and work very well. Currently SITE a (10.10.0.0/16) connects to the SITE B (10.20.0.0/16). SITE A connects to SITE C (10.100.8.0/21). These are OK.
What is a failure is when I try to connect SITE B to SITE C. The tunnel coming up and phase 1 and 2 complete successfully. However, even if in the course of execution: ' entry packet - trace within the icmp 10.20.8.2 8 0 detailed 10.100.8.1 ' I get the following:
Phase: 10
Type: VPN
Subtype: encrypt
Result: DECLINE
Config:
Additional information:
Direct flow from returns search rule:
ID = 0xad1c4500, priority = 70, domain = encrypt, deny = false
hits = 609, user_data = 0 x 0, cs_id = 0xad1c2e10, reverse, flags = 0 x 0 = 0 protocol
SRC ip = 10.20.0.0, mask is 255.255.0.0, port = 0
DST ip = 10.100.8.0, mask is 255.255.248.0, port = 0, dscp = 0 x 0
I noticed that when the tunnel came, the road to 10.100.8.0/21 was added in the routing table and cyrpto what ACL has not been applied on the SAA remote. I added the route manually but cannot get the cryto ACL to apply.

clear crypto ipsec its SITE_B_Public peer
Try again and attach the same outputs.
Let me know.
Thank you.

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.
See the crypto Isakamp SA
See the crypto Ipsec SA

Cisco ASA 5505 VPN Site to Site
Hi all
First post on the forums. I have worked with Cisco ASA 5505 for a few months and I recently bought a 2nd ASA to implement tunnel VPN Site to Site. It seems so simple in the number of videos watched on the internet. But when I did he surprise it did work for me... I've removed the tunnels, a number of times and tried to recreate. I use the VPN Wizard in the SMA to create the tunnel. Both the asa 5505 of are and have the same firmware even etc..
I'd appreciate any help that can be directed to this problem please. Slowly losing my mind
Please see details below:

: endHello
There are some clear problems I see on a quick glance. These are not related to the actual VPN configuration but rather the NAT configurations.
All your configuration of NAT CLI format above are configured as manual NAT / double NAT in Section 1. This means that the appliance NAT configurations have been added to the same section of the NAT configurations and scheduling of the NAT inside this Section rules is the cause of the problem for the L2L VPN connection for some.
Here are a few suggestions on what to change
ASA1
Minimal changes
the object of the LAN network
192.168.10.0 subnet 255.255.255.0
being REMOTE-LAN network
255.255.255.0 subnet 192.168.100.0
NAT (inside, outside) 1 static source LAN LAN to static destination REMOTE - LAN LAN
no nat source (indoor, outdoor) public static NETWORK_OBJ_192.168.10.0_24 NETWORK_OBJ_192.168.10.0_24 NETWORK_OBJ_192.168.100.0_24 NETWORK_OBJ_192.168.100.0_24 non-proxy-arp-search of route static destination
That means foregoing is first of all create 'object' that contain the local LAN and remote LANs. Then, it creates a NAT0 rule and adds to the top rules NAT. (number 1). It is essentially of at least one of the problems preventing the VPN operation or traffic that cross.
Finally, we remove the old rule that generated the ASDM. It would do the same thing if it has been moved to the top, but I generally find the creation of the 'object' with descriptive names easier on the eyes in the long term.
Other suggestions
These changes are not necessary with regard to the VPN L2L. Here are some suggestions how to clean a part of NAT configurations.
PAT-SOURCE network object-group
source networks internal PAT Description
object-network 192.168.10.0 255.255.255.0
object-network 192.168.20.0 255.255.255.0
object-network 192.168.40.0 255.255.255.0
NAT interface (it is, outside) the after-service automatic PAT-SOURCE dynamic source
No source (indoor, outdoor) nat Dynamics one interface
no nat (wireless, outdoors) source Dynamics one interface
no nat (servers, outside) no matter what source dynamic interface
The above configuration creates a "object-group" that lists all internal networks that you have dynamic PAT configured so far. It then uses the ' object-group ' in a command unique 'nat' to manage the dynamic PAT for all internal networks (with the exception of printers who had nothing at first). Then we remove the old PAT dynamic configurations.
Contains the command "nat" "car after" because it moving this "nat" configuration to the bottom of the NAT rules. For this reason its less likely to cause problems in the future.
network of the SERVERS object
subnet 192.168.20.0 255.255.255.0
network of the VPN-POOL object
192.168.50.0 subnet 255.255.255.0
NAT (servers, external) 2 static static source of destination of SERVERS SERVERS VPN-VPN-POOL
no nat (servers, external) static source NETWORK_OBJ_192.168.20.0_24 NETWORK_OBJ_192.168.20.0_24 NETWORK_OBJ_192.168.50.0_24 NETWORK_OBJ_192.168.50.0_24 non-proxy-arp-search of route static destination
The above configuration is supposed to create a NAT0 configuration for traffic between the network and the pool of Client VPN server. To my knowledge the old configuration that remove us is not used because the traffic would have matched PAT rule dynamic server yet rather than this rule which is later in the NAT configurations and would not be addressed.
no nat source (indoor, outdoor) public static NETWORK_OBJ_192.168.10.0_24 NETWORK_OBJ_192.168.10.0_24 NETWORK_OBJ_192.168.1.0_24 NETWORK_OBJ_192.168.1.0_24 non-proxy-arp-search of route static destination
It seems to me that network 192.168.1.0/24 is not configured from anywhere in your network. Therefore, the above 'nat' configuration seems useless, can be deleted. If I missed something and its use in then of course do not remove it.
ASA2
Minimal changes
the object of the LAN network
255.255.255.0 subnet 192.168.100.0
being REMOTE-LAN network
192.168.10.0 subnet 255.255.255.0
NAT (inside, outside) 1 static source LAN LAN to static destination REMOTE - LAN LAN
no nat source (indoor, outdoor) public static NETWORK_OBJ_192.168.100.0_24 NETWORK_OBJ_192.168.100.0_24 NETWORK_OBJ_192.168.10.0_24 NETWORK_OBJ_192.168.10.0_24 non-proxy-arp-search of route static destination
That means foregoing is first of all create 'object' that contain the local LAN and remote LANs. Then, it creates a NAT0 rule and adds to the top rules NAT. (number 1). It is essentially of at least one of the problems preventing the VPN operation or traffic that cross.
Finally, we remove the old rule that generated the ASDM.
Other suggestions
PAT-SOURCE network object-group
object-network 192.168.100.0 255.255.255.0
NAT interface (it is, outside) the after-service automatic PAT-SOURCE dynamic source
No source (indoor, outdoor) nat Dynamics one interface
The above configuration is supposed to do the same thing with the other ASA. Although given that this network contains only a single subnet it cleans the "nat" configurations exist that much. But the order of the "nat" configurations is changed to avoid further problems with the NAT order.
no nat source (indoor, outdoor) public static NETWORK_OBJ_192.168.100.0_24 NETWORK_OBJ_192.168.100.0_24 NETWORK_OBJ_192.168.1.0_24 NETWORK_OBJ_192.168.1.0_24 non-proxy-arp-search of route static destination
It seems to me that network 192.168.1.0/24 is not configured from anywhere in your network. Therefore, the above 'nat' configuration seems useless, can be deleted. If I missed something and its use in then of course do not remove it.
I suggest trying the changes related to VPN L2L first NAT0 configurations and test traffic. So who gets the work of connectivity, then you could consider changing other NAT configurations. There are other things that could be changed also in what concerns THAT static NAT servers but that probably better left for another time.
Hope this makes any sense and has helped

Hi Javi,
Please after the release of "see broadcasting DfltGrpPolicy of any political group." See if you have the "vpn-idle-timoeout" command configured in that. If so, please change to "vpn-idle-timeout no" and see if that stops at these popping up error messages.

Routing with Cisco ASA 5520 VPN
I have installed IPsec vpn remote users in the Cisco ASA 5520 using RADIUS in my main network. Works very well. I have a site to my Cisco ASA5520 tunnels going to other sites, some of the tunnels have Cisco ASA and some have SonicWalls. I wish that my users VPN remote IPSec to be able to navigate in these tunnels is a site to access remote subnets attached to these tunnels. Do I need to use a combination of routing and the ACL? Or can I just use ACL only? Or just use routing only?
Thank you
Carlos
Hello
The key to set up here is the two ACL of VPN L2L end points that determine the 'interesting' traffic to connect VPN L2L. You will also need to confirm that the connection of the VPN Client is configured so that traffic to the remote sites have sent to the connection of the VPN client. There are also other things that you should check on your ASA plant
Here most of the things you usually have to confirm
- Set up 'permit same-security-traffic intra-interface' if it is already present in your configuration
- This setting will allow connections to form between the hosts that are connected to the same interface on the ASA. In this case, applies because the VPN client users are connected to the interface 'outside' of the ASA and also remote sites are connected to the ASA to "external". If the traffic between the remote VPN Client and VPN L2L sites will be to enter and exit the same interface
- You will need to check how the customer if configured VPN connection. Split or full Tunnel tunnel
- If the connection of the VPN Client is configured as Split Tunnel then you need to add all the networks from the remote to the Split Tunnel, so that the connections between the VPN Client is transmitted to the ASA and from there connections VPN L2L
- If the connection of the VPN Client is configured as full Tunnel, then there no problem that all traffic is transferred to the Client VPN connection all its assets
- Define the VPN pool in the ACL of VPN L2L
- You should make sure that the pool network VPN Client is defined in the ACL that define 'interesting' traffic to connect VPN L2L. So, you need to add the pool VPN VPN L2L configurations on the sites of Central America and remote control
- Configure NAT0 / NAT exempt for remote VPN Client to L2L VPN Site traffic at both ends of the VPN L2L
- You must ensure that the NAT0 / exempt NAT rules exist for the VPN Client for Remote Site traffic. This will have to be configured on the SAA "outside" interface. Format of configuration varies naturally a bit on the ASA Central his software level.
These should be the most common things to set up and confirm for traffic to flow between the VPN Client and Remote Sites
Hope this helps please rate if yes or ask more if necessary.

Cisco ASA 5505 VPN passthrough
Hello
@home i'f installed a Cisco asa 5505 because the provider has the modem cable in transparent mode. So I have the public IP address to my firewall.
Also for the training because we have in the work of the asa. So I have no feeling with her.
but sometimes I have to build a VPN session to a server at work. But I do not get a connection to the server. If I remove the ASA 5505, then the connection to the server of work is great. But if to ASA 5505 is back in its place. It does not log VPN to the outside world.
Could someone point me in the right direction?
It is possible to create a connection out to the Cisco ASA5505 VPN.
Thanks in advance
Greetings
Palermo
Hi Palermo,
You do not have to mention the type of VPN connection, you use.
If the PPTP protocol then you need to inspect the traffic for the SAA allow again from 'outside '. Try the following:
! class-map inspection_default match default-inspection-traffic ! policy-map global_policy class inspection_default inspect pptp ! service-policy global_policy global !
see you soon,
SEB.

Cisco ASA - l2l IPSEC tunnel two dynamic hosts
Hello
I have two firewall Cisco ASA an i want to made a l2l between two ipsec tunnel, the problem is that both parties have a dynamic IP, on both sides I have configured dyndns, can I did an ipsec tunnel using dyndns name such as address peer?
Hello
ASA supports only the RFC compliant method for updates used with dynamic DNS, not updates HTTP, such as dyndns.org and others use.
i.e. https://tools.cisco.com/bugsearch/bug/CSCsk25102/?reffering_site=dumpcrOn ASA, it is not possible to configure the tunnel between two dynamic peers.
You will need to have a static end to configure static to dynamic IP.For routers, you can follow this link.
I hope this helps.Kind regards

We have a partner that we set up a VPN L2L with. Their internal host IP infringes on our internal IP range. Unfortunately, they are not offer NAT on their side. Is it possible on the SAA to configure a NAT device for my internal hosts will say 1.1.1.1 and ASA changes the internal address of the remote end overlapping?
If this is the scenario
192.168.5.0 ASA1 <---> <-- internet="" --="">ASA2<-->
ASA1 (NAT will be applied)
ASA2 (without nat will be applied)
You want to do something like that on ASA1
Change your source host or network to be 192.168.7.0 when communicating with the remote network. Change the remote network to come as long as 192.168.8.0 coming to your network on the SAA.

Complete the VPN configuration using acl_match_VPN as the ACL match. Your inside host will have to use the 192.168.7.0 network when you talk to the remote end.
I hope this helps.

ASA L2L VPN UP with incoming traffic
Hello
I need help with this one, I have two identical VPN tunnel with two different customers who need access to one of our internal server, one of them (customer) works well, but the other (CustomerB) I can only see traffic from the remote peer (ok, RX but no TX).

Hello
It seems that the ASA is not Encrypting traffic to the second peer (However there is no problem of routing).
I saw this 7.x code behaviors not on code 8.x
However you can do a test?
You can change the order of cryptographic cards?
card crypto outside_map 1 match address outside_cryptomap
peer set card crypto outside_map 1 160.160.143.4
map outside_map 1 set of transformation-ESP-3DES-MD5 crypto
card crypto outside_map 3 match address outside_1_cryptomap
card crypto outside_map 3 set pfs
peer set card crypto outside_map 3 200.200.200.200
card crypto outside_map 3 game of transformation-ESP-3DES-SHA
I just want to see if by setting the peer nonworking time to be the first, it works...
I know it should work the way you have it, I just want to see if this is the same behavior I've seen.
Thank you.
Federico.

Hi all.
I search the internet to find a way or all first, whether it is possible to do what I want to do, but I can't find anything corresponding to what I'm looking for. Possible that I don't have the right keyword.
We change our old Pix 515e this weekend and for any new ASA 5510.
With this new facility, I want to implement Radius Authentication for the user remote vpn. Change the firewall of the company is an important factor and for the first phase, the user will keep authenticate locally but I need that in phase 2, they will be authenticated through a radius server.
Is there a way to configure both user authentication remote vpn?
For example.
All users will be authenticated locally unless the service member COMPUTER that is authenticated by the radius to the testing server.
I have remote vpn users anywhere in the world if I don't want these users are blocked by the radius authentication test. What I want is that users in Group1 will be authenticated locally on the SAA and users in group2 will be authenticated by the RADIUS. During the test will be done, all users will gradually transfer for radius authentication.
Is it possible
Thank you

Hi Jonathan,.
The best way to go about this would be that you set up another group strategy & corresponding tunnel group named Test and set up Radius Authentication for VPN group using the link below: -.
Ones you have done test and feel confident, you can change the type of authentication for the Production Group. The reverse could be implemented double authentication as RADIUS and if it does not use local but personally I'll put up a group of test and then those I am confident, that I'll change the strategy of Production Group to use the Radius Server to auth.

ASA at the ASA L2L VPN Firewall
Hi experts,
I currently have problems establishing a VPN site-to-site easy. It's my first time at this meeting and I am pulling my hair out for this issue.
Currently, the installation program below is a typical topology (using ASDM):
An ASA IP (1.1.1.2) of the site <-->(ISP) <-->Site B (ASA IP 2.2.2.2)
All ASA IPs are the external interface connecting directly to their respective suppliers. Site has existing VPN tunnels to other networks, but Site B is a new network configuration (one can imagine Site A as a hub and the rest are rays). Site B outside interface opened ports IP 50 ESP, UDP 500 and UDP 4500 on the interface of all sources to connect to the external interface (besides us has allowed all the IP protocol for the external interface for troubleshooting). However, we have issues that phase 1 upward. We have carefully matched and double checked IKEv1 all the settings are correct and the same for the two parties, including the PSK. However Site A can ping IP of the Site B and Site B is not able to ping to the Site A IP.
We also checked with our Internet service providers and they confirmed that they do not block 3 ports we need for the VPN. Is there more ideas or points that we missed?
Oh, activation of debugging are not returned all the papers, but will help generate some 'interesting' traffic such as internal ping subnet of Site A of the Site B?
Hello
Instead of launching the plotter of the interface IP packets use all other inside IP, I see a failure of ifc interface.
Also is it possible for you to take the UDP 500 captures on the external interfaces on the SAA?
This would answer a lot of questions.
Kind regards
Aditya

Cisco ASA - Anyconnect VPN - DAP to restrict access
Hello
I havn't any way proven or description if this is possible with the asa. I'm trying to find a solution were based on the users of Active Directory groups are only in the use of VPN.
I wannt all "AllVPNUsers" users are able to connect and can only access a server in-house.
If a user is in the group "AllDevelopers-VPN" they should be able to access all the servers in a specified subnet
If a user is in the "AllDevOps" group they should not have any restrictions.
is it possible with one asa 5512-X?
Best regards
Daniel
Hi Daniel,.
You can use mapping of LDAP attributes where one ad group can be mapped to a group policy which will give access to specific networks.
Here is a document that you can reference. Please do not hesitate to share if there is no problem.Kind regards

How L2L WCCP vpn tunnel? If there is a Web page on the otherside of the tunnel that I need access on ports 80 and 443, it goes through the process of WCCP. How will I know the traffic through the tunnel for 80 and 443 to ignore the WCCP?
Hello
I have not had to deal with WCCP on the SAA configurations as it, but to my knowledge, this could be done in the ACL that is used in configuring WCCP on the SAA.
I mean a single montage we have has an ACL that simply bypasses the WCCP for some destination addresses.
The ACL was originally for example
WCCP ip access list allow a whole
Then we had to stop it for some destination network and we would add a Deny statement at the top of the ACL
access-list 1 deny ip WCCP line any 10.10.10.0 255.255.255.0

Can you please check see the version attached and explain, if I run with licenses right into place.

SecIT
Hello
You've got license for 250 users anyconnect so unless you are having more users than this number, it shouldn't be a problem. Debugs could help reduce the problem in this case.
