VPN question on encryption
Hi all
I am currently studying my CCNA to the University and we are doing a group project and must implement a vpn encrypted tunnel. It's a lab environment that is the reason why ports fast ethernet are used for the wan between sites link. Our tunnel works as we only eigrp ajacency when the tunnel is enabled, but is not encrypt the traffic. I pasted the config for both routers below in the hope that someone will spot the problem etc. of the missing parameter. Thanks in advance:

Hello
1. cryptographic maps on tunnel interfaces are not supported. You can remove that?
2. your crypto ACL should be allowed free will host 192.168.100.29 host 192.168.200.30 [since you want to protect free WILL - so select you the points end tunnel source and destination]
See you soon,.

Question about encryption for a VPN established between two of our sites
We have two routers Cisco 2951, one at our main location and one at a branch. An engineer for a local company came and worked all the parameters, including the VPN between the two men.
For an upcoming exam, the firm wanted to know what kind of security/encryption has been implemented between the two routers. The engineer is no longer available, so I've went over our configuration files for each of the routers and will have questions about what to tell them (I'll be the first to admit that some of this stuff is over my head).
I enclose the portions of the configs with "crypto" information he put in place. If you see something wrong, or need something extra, let me know.
Thanks in advance!
That's what you use:
Phase 1: 3DES, SHA1, PSK, Group2 DH (1024 bits), life time 86400 s
Phase2: 3DES, SHA1
Which is today considered legacy crypto, but probably nothing to worry. The crypto-config has always considered that there is "room for improvement"...

I am ASA 5505 that I am of is running correctly by using the AnyConnect client. The question is, can I connect to the fine external interface, but cannot ping or attach them to any host on the inside. When I connect, it accepts the user name and password, and I can run the ASDM or SSH to the firewall very well, but not further. In the control, after I log in, I get an IP address inside, of the order of 10.7.30.x as expected.

Hello
Please, add this line in your configuration and let me know if it works:
access extensive list ip 10.7.30.0 inside_nat0_outbound allow 255.255.255.0 10.7.30.0 255.255.255.0
I ask you to add that it is because you have not specified any exceptions for the return shipping. Once you add to it, will allow you to go through the tunnel VPN, packets back. When this command is not there, you will be able to access everything on the SAA but nothing behind it.
Let me know if it helps.
Thank you

Try to find what happened. I had the remote end raise the tunnel, as they can ping resources on my side. I am unable to ping 10.90.238.148 through this tunnel. I used to be able to until the interface of K_Inc has been added. The network behind this interface is 10/8.
I asked a question earlier in another post and advises him to play opposite road of Cryptography. And who did it. I was able to ping 10.90.238.148 of 192.168.141.10, with the config below.
I am at a loss to why I can't all of a sudden. A bit of history, given routes have not changed. By adding the command set opposite road to cryptography, I find myself with a static entry for the 10.90.238.0 network is what fixed it initially so I don't think it's a problem of route. The remote end had an overlap with the 192.168.141.0/24 that is why my side is natted on the 10.40.27.0. None of the nats have changed so if adding the reverse route worked for a day, it should still work. Any thoughts?

What version are you running to ASA?
My guess is that your two static NAT is configured above policy nat you have configured for the VPN? If this is the case, move your above these static NAT NAT policy and you should see the traffic start to flow properly.

Hi, I use the windows Server 2003 and. When I access my server at home I connect the VPN but I not have access to the shared private folder when I try to open the system crashes but the other file I can open without blocking. Please help me solve this problem...

3 questions about encryption on the Z5
Hi, I have three questions to ask other Xperia users.
If I decide to encrypt my phone (Z5):
(1) what will be the star of the performance? It will be noticeable?
(2) I know it is not compatible with the smart lock, but it will make it also impossible to unlock the phone by using the fingerprint reader, knowing that this feature uses a proprietary API in its current form of "Lollipop"? (Good thing Marshmallow natively supports it)
(3) again, it will be possible to use and update my phone with Flashtool?
Thank you
Hey, I have improved my Z5P yesterday to 6.0 using flashtool, so I can help
(1) not for me / I have no comparison
(2) totally compatible. Fingerprints don't worked with LL, as well as with mm. Fingerprint req. a code pin or password then, no reason
(3) totally, Yes. BUT: I have my sdcard BA. Well, and not have suffered in some way the cryptokey erased (something like that), so I had to restore a backup that I did the day before. The files are always there, they just cannot be opened. Memory as before interior work, without loss of data.
Cheers.

I have two questions that regarding ACL is used in the instructions on the Card Crypto:
1. the two devices VPN should have the same ACE in the ACL? I know that without the second ACE site B below will not see as interesting udp traffic, but the will of the vpn tunnel fails because the ACL is not the same ACE?
That is to say...
Site has
Access-list 110 permit tcp 10.0.1.0 255.255.255.0 10.0.2.0 255.255.255.0
Access-list 110 permit udp 10.0.1.0 255.255.255.0 10.0.2.0 255.255.255.0
Site B
Access-list 110 permit tcp 10.0.2.0 255.255.255.0 10.0.1.0 255.255.255.0
2. once a tunnel is established it will send ANY/ALL traffic destined to the remote network through this tunnel. If the first ACE in the ACL 110 to Site A list is used to bring up the tunnel, only tcp from to 10.0.2.0/24 10.0.1.0/24 traffic will use the tunnel or all traffic from 10.0.1.0/24 intended for the remote network to cross the tunnel?
I guess my thought is this. The ACL is only used to determine valuable traffic and once the tunnel is up it is a free for all. Or the ACL only allows traffic that meets the criteria specified in the ACL list to flow once the tunnel is established?
Thank you
Brian
Brian,
Your statement
'Or the ACL allows only traffic that meets the criteria specified in the ACL list to flow after the tunnel is established'
Is correct, only the traffic that meets the ACL crypto will go through the vpn tunnel and all other traffic will be denied. If you need UDP traffic to travel through the tunnel, you need crypto ACL on both sides and not only on one side, that is, SITE A.
Hope this helps,
Jay

Hello
I created a vpn between two routers in two different sites. The VPN works well, but I noticed something that I can ping from peer1 at peer2 however the tunnel although the ACL of the interesting traffic allows no icmp between two counterparts, it is configured as follows:
access-list 120 allow ip 10.10.10.0 255.255.255.0 192.168.2.0 255.255.255.0
access-list 120 allow ip 1.1.1.1 host 2.2.2.2
No icmp is allowed, but the icmp traffic is encapsulated, encrypted, and through the tunnel, why?
Hello moahmed1981,
When you configure access-list for IPs, so it includes ICMP, TCP, and UDP, therefore, it is expected that you will be able to ping across the tunnel.
If you want to change this, please configure the VPN filter to prevent the ping to the vpn tunnel.
Here's a doc for your reference:-

Any help greatly appreciated
So, you want to have two virtual private networks from Amazon to blocks of different destinations, 10.32.0.0/16, and 10.34.0.0/16, correct?

Hello world
The vendor name is implemented server in our environment.
We implement VPN site-to-site.
Subnet it is interesting traffic 192.168.50.x
Server IP 192.168.50.1 - Switch1 - ASA - Site to site VPN - provider ASA.
Gateway server is on switch1 if this server requires access to the internet I need to know what config I need on ASA on my site?
I want the server to access the internet through the provider network
Concerning
Mahesh
Hello
Your crypto ACL would be:
ip access-list VPN-TO-VENDOR permit ip 192.168.50.0 255.255.255.0 any

VPN question: ISP assigned a private ip address
Hi all
Internet-online-online headquarters VPN 3015 concentrator
Users remote VPN Client connected to the internet using a private ip address provided by the ISP (cable) is to establish a VPN tunnel, but they can not ping our private network.
The only way to get the VPN works is when remote users use a public ip.
It is a question of Cisco VPN Client? Or it has a solution...
Thanks in advance,
Kind regards
Carlos Welhous
Network engineer
Hi Carlos,
If your ISP gave you a private address, they must use NAT - in which case you will have to enable NAT - T on the VPN concentrator.
To configure the NAT - T in the world, go to Configuration | System | Tunnelling protocols. IPSec | Screen of transparent NAT and check on NAT - T IPSec case.

VPN - question of General design for a ut of a router tunnel more
Hello
We have a router that has VPN connections with different partners of our company. VPN remote access were used on computers that are connecting to the different partners of our company.
There has been problems of this kind, that is to say put on both a watchdog and a customer vpn cisco router led to blue-screens on the PC.
The current idea is to put different tunnels from site to site on the router (default gateway of PC clients that connect to the partners). My question is... How our PC to get DHCP addresses on networks of visitors, once the tunnels are up? I guess I'm alittle confused about the address for the PC on our side how will work.
Thanks for your help.
Divide the pool of ip from the internal network, you're going to visit. for example the document below will be exaplain the same configuration in user mode.

Site to site VPN question: passing a public IP with IPSEC
Hi all
I need to create a VPN tunnel site to site using IPSEC between two offices on the Internet. The offices belong to two different companies.
They gave me a series of 16 public IP addresses. One of these IP addresses is used on the ISP router and this is the next hop for my router. Another IP in the range is used on my router? s external interface (which is a Cisco 851) and he is also my site VPN endpoint. So far so good...
Here's my problem: the IP source of encrypted traffic, is a public address from within the IPs public 16 I (not the one on my router interface). The actual application that needs to send the encrypted data is a server in my local network, and it has a private IP address. The other site, expects to receive data, however, the public IP address. I used NAT between the private IP address of the server and its public IP address, but no data goes through the tunnel. Moreover, the tunnel between the two end points established without problem. The problem is that the source of my encrypted data is the public IP address and I don't know how to get through the tunnel. I enclose my router configuration.
Any help is appreciated.
The access list "natted-traffic" should say:
extended traffic natted IP access list
deny ip host 192.168.0.160 BB. ABM ABM BD
deny ip host 192.168.0.160 BB. ABM BB.BE
output
I hope this helps.

SSL VPN recommendation without encryption RC4
Hello
Actually I m using Annyconnect in ASA with SSL RC4 Cipher Suites taken care of, vulnerability it is recommended to use without RC4 encryption.
The question is, there is a document illustrating the best practices or recommendations to do?, I Don t know if it has an impact in this change, or if it is supported in the code.
Concerning
Ricardo
Ricardo,
Recommendations:
http://www.Cisco.com/Web/about/security/intelligence/nextgen_crypto.html#15
The impact is usually double that:
-All clients/browsers will support new encryption algorithms
-What level of computational overhead will be presented.
ASA side it is a cryptographic chip that is quite effective at handling in general crypto.
If your clients support address allowing DHE based ciphers.
I don't think there is a big best practices doc avilable, need a little more on the environment.

L2l - a non-reachable subnet VPN question
Hi people,
I have a strange problem with a new VPN connection and would appreciate any help.
I have a pair of Cisco asa 5540 s configured as a failover pair (code version 8.2 (5)).
Recently, I added 2 new VPN L2L - these two VPNS come from the same interface on my ASA (called Internet service provider) and both are to the same customer, but they end the different firewall on the end of cusomter and different client subnets traffic encryption. There is a basic network diagram attached.
1 - the VPN is for customer subnet 10.2.1.0/24 traffic. Devices in this subnet should have access to 2 subnets on my network - DMZ 211 (192.168.211.0./24) and DMZ 144 (192.168.144.0/24). This VPN working properly.
2 - the VPN is for the subnet 192.168.1.0/24 customer traffic. Devices in this subnet should be able to access the same 2 subnets on my network - DMZ 211 (192.168.211.0./24) and DMZ 144 (192.168.144.0/24). What VPN does not work - the client can access 144 DMZ, but not of DMZ 211.
There is a SAs isakmp and ipsec for two virtual private networks. I noticed that the program/decaps packages counter does not increment when the client sends the test traffic to 211 of the DMZ. This counter will increment when they send traffic test to DMZ144. I also see the traffic sent to 144 DMZ customer subnet 192.168.1.0/24 in packet capture on the interface DMZ 144 of the ASA. I don't see similar traffic capture on the interface DMZ211 (although I can see the traffic sent to DMZ211, if it is from 10.2.1.0/24 - IE when using VPN1)
Exemption of NAT is configured for 192.168.1.0/24 and 10.2.1.0/24.
There is a road to two client subnets via the same next hop.
There is nothing in the unknown newspapers 192.168.1.0/24 traffic has been ignored
I suspect that this may be a problem on the client side, but I would like to be able to prove that. Specifically, I'd like to really be able to capture traffic destined to 211 DMZ on the interface of the firewall after her Internet service provider has been deciphered - I don't know if this can be done however, and I haven'treally has found a good way to prove or disprove that the 192.168.1.0/24 DMZ211 VPN traffic coming to my ASA Internet service provider interface and show what happens to This traffic, after his arrival.
Here is the relevant vpn configuration:

The counters of compensation was a good idea. If the counter is not incremented and ping the remote side is not cause future VPN it certainly confirms that something is not working properly.
It might be interesting to wait the SAs time out and go idle and test it again with the ping to the remote subnet that does not work. Turn on debugging for ISAKMP and see if there is an attempt of negotiation. Especially if you don't get any attempt to open ISAKMP then so it would be a way of showing that there is a problem on the remote site.
Certainly, the ASA has the ability to capture packets. I've used this feature and it can be very useful. I have not tried to make a catch on the external interface for incoming VPN traffic and so not sure if you would be available to capture the encrypted packet or the off encrypted packet. You can configure an access list to identify traffic capture and I guess you could write an access list that included the two addresses as source and destination peer to capture encrypted traffic and the Scriptures that were unencrypted source and destination subnets to capture traffic after encryption.
