Output of "crypto ipsec to show her.

Hello

In a VPN l2l baseline using ezVPN, the server behind the NAT, client device using 3 G. What would be the reason to have the output of the show crypto ipsec sa, a current peer differs from crypto remote endpoint on the server?

Thanks for your help.

David

Given that it is behind a NAT and NAT device is only the layer 3, and it changes the contents of the IPSec VPN when negotiating because it is encrypted, so you might see counterpart current differs from endpoint remote crypto on the server.

Hello Manu,

Virtually every SA will show you the traffic that is sent over the VPN (which is innitiating the traffic) in this case, we can see that we send on the VPN tunnel traffic from 10.10.x.x subnet other 10.

Interesting CRYPTO ipsec traffic - need some understanding

Hi friends,

I need your help to understand the works of tunnel passing crypto ipsec. It is always said that valuable traffic to the times needs to be mirror config. Now my doubt is if I add a host of 10.10.10.10/32 entry at one end and add an entry for network 10.10.10.0/24 to the other end, it will work? If it's not there? According to the logic that this host 10.10.10.10 has work I am rite? Sometimes back I met this senario where part of the IP'S work and other is... ". After checking the config we experienced that one side has been added to it like 24 and another there are 25.

Ipsec tunnel will exchange their interesting traffic ACL acoss each other what phase 2 is coming? What happens if I add the above said 10.10.10.10 stuff in tunnel work already... It will cause any problem?

Awaiting your response

Thanks & best regards,

Kamal

The simple answer to your question is Yes, a entity 32 on one side of the tunnel should work if the network is defined as a 24 on both sides. This isn't like a list of prefixes or routing protocol dynamic where subnet masks must match. Statements of network in the passage from Phase 2 of the IPSEC tunnel (which defines which traffic runs through the tunnel) are defined through ACL, so as long as the traffic meets the criteria of the ACL, then go above the tunnel. That being said, your tunnel of phase 2 should have never been created in your 24 & 25 example because network statements not matching - it's weird. Maybe your tunnels put in correspondence, but you exclude some of the traffic to be NAT'ed?

As you we, however, portions of the phase 2 of the tunnel (aka security association) must be mirror images. If you use two ASAs then you can simply reverse ACL source and destination. If you make the ASA for say, a netscreen, it may be a little more complex depending on whether you're doing road or political from ipsec on this side there. If you can't get the 32 device work for some reason, you can also create another specific to this traffic safety association.

Capacity of the crypto ipsec Cisco ASA 9.1 stats system failures

I'm trying to find some performance issues on one ASA centralized and some site VPN settings. I already address bits of fragmentation and flow control which seeks to solve performance problems, but I came across something that I can't identify to understand what he said.

I can't seem to find any documentation that explains what triggers the counter for "Capacity of the system failures" on the stats command see the crypto ipsec:

What is the model of the ASA you have and how many vpn sessions you get on average during peak hours?

Lack of capacity occurs when it is short of ability of the material or the use...

What part of a PC is responsible for showing her very small details in the design?

I am currently using photoshop in learning graphic and web design.
I use a PC with a low graphics (about 512 MB) memory and a samsung syncmaster 226BW 22inches.
I noticed that, while following a graphic design tutorial, but eventually, I'll add a layer style that does not appear on my screen or even on my laptop screen and find themselves without effect on the overall design.
This happens often. For example, I could design an icon and then carry on the verification and uncheck an INTERNAL GLOW (or another layer model), I see no difference in the design. I realize that's not good for me as a designer of learning.
Now, I am planning to change my monitor or my PC.
I would be happy to know what needs to be changed. Is it my PC, my monitor or BOTH (judging by my pc and monitor specs).
I'd be happy to get guidance on this issue.
Thank you very much!

These issues have little or nothing to do with the ram. You must find a way to calibrate your monitor, so the colors are more specific to the data in your documents. Realize that monitors also have a life and generally degrade some with age. If your screen is old, even a large calibration could not help a lot.

Hello all I could use help before I cry

I have my main office 5510. I have 4 remote offices with 5505. These 4 Office Connection VPN L2L at my main desk with NO problems and have for a few years.
We have recently added a 5th with yet another office 5505. So I do the same, through the new office main office VPN. But for the life of me, I can't seem to get it to connect. I used the same set up on the NEW Office that I have done all the old office, but for some reason, I can't establish a tunnel / connection.

One thing that warns me initially is the ACL for the encryption field and nat exemption. Is the remote site really to 192. 198. 10.0 / 24 or 192. 168. 10.0 / 24?

106 extended access-list allow ip 192.168.90.0 255.255.255.0 192.198.10.0 255.255.255.0

```
Other than that, the configuration, to me, seems good, assuming you have the same ISAKMP and IPSEC configuration on the side of 5510.

sheep allowed 10 route map

corresponds to the IP 110

The parts of the configuration you posted seem better than earlier versions of the config. The initial problem was that traffic was not in the VPN tunnel. That works now?

Here are the things I see in your config

I don't understand the relationship of these 2 static routes by default. It identifies completely the next hop and a mask the bytes of Middleweight of the next hop. Sort of, it seems that they might be the same. But if they were the same, I don't understand why they both make their appearance in the config. Can provide you details?

IP route 0.0.0.0 0.0.0.0 62.X.X... 121

IP route 0.0.0.0 0.0.0.0 62.172.32.121

This static route implies that there is another network (10.2.0/24) connected through the LAN. But there is no other reference to it and especially not for this translation. So I wonder how it works?

IP route 10.2.0.0 255.255.255.0 192.168.20.2

In this pair of static routes, the second route is a specific subnet more and would be included in the first and routes for the next of the same break. So I wonder why they are there are. There is not necessarily a problem, but is perhaps something that could be cleaned up.

IP route 172.17.0.0 255.255.0.0 Tunnel20

IP route 172.17.2.0 255.255.255.0 Tunnel20

And these 2 static routes are similar. The second is a more precise indication and would be included in the first. And it is referred to the same next hop. So why have the other?

IP route 172.18.0.0 255.255.0.0 Tunnel20

IP route 172.18.0.0 Tunnel20 255.255.255.252

How to troubleshoot an IPSec tunnel GRE?

Hello

My topology includes two firewalls connected through the Internet "" (router) and behind each firewall, there is a router.

The routers I configured a GRE tunnel that is successful, then I configured an IPsec tunnel on the firewall.

I does not change the mode to transport mode in the transform-set configuration.

Everything works; If I connect a PC to the router, it can ping another PC on the other router. However if I change mode of transport mode that they cannot.

I was wondering how can I ensure that the IPSec tunnel WILL really works? How can I fix it or package tracking?

Thank you.

I was wondering how can I ensure that the IPSec tunnel WILL really works? How can I fix it or package tracking?

To verify that the VPN tunnel works well, check the output of
ISAKMP crypto to show his
Crypto ipsec to show his

Here are the commands of debug
Debug condition crypto x.x.x.x, where x.x.x.x IP = peer peer
Debug crypto isakmp 200
Debug crypto ipsec 200

You will see ACTIVE int the first output and program non-zero and decaps on the output of the latter.

For the GRE tunnel.
check the condition of the tunnel via "int ip see the brief.

In addition, you can configure keepalive via the command:

Router # configure terminal
Router (config) #interface tunnel0
Router(Config-if) 5 4 #keepalive

and then run "debug keepalive tunnel" to see packets hello tunnel going and coming from the router.

If this type of network is called free WILL on the right of IPSEC?

Need to understand which shows that data transmitted by tunnel LIKING which is not encrypted right?

To verify ipsec ASA which is encrypted data that we do sh right its isakmp crypto?

When we apply crypto map on the physical interface ASA here?

Thank you

Mahesh

If your GRE tunnel protection applied to this topic, so I think that the transmitted data is encrypted. GRE over ipsec simply means the application of the protection of tunnel to tunnel will otherwise it's just a simple GRE tunnel.

Side that Show crypto isakmp his, you can also check if the traffic from one site to another is using GRE or not by issuing crypto ipsec to show its, it will tell you the number of Protocol and it should say 47. And if you use the protection tunnel command to set the ipsec tunnel, you will not need to define cryptographic cards more.

2 IPSec VPN + DMVPN

Hello.

Could you please tell me, how to create the second IPSec VPN on my router if crypto card is already set to the interface, and there is no other. This interface is also the NHRP\DMVPN interface. Router is a hub.

Hey, Nikolay.

For new dmvpn cloud you don't don't have set up a crmap to the interface. You can create a new tunnel interface and link a different transfer for her.

If you want to add an IPsec-l2l connection or a new EasyVPN you can look at this example:

Crypto ipsec transform-set esp-3des esp-md5-hmac trset1
transport mode
output

Crypto ipsec transform-set trset2 aes - esp esp-sha-hmac

map CRNAME 1 ipsec-isakmp crypto
Description - VPN - 1
defined peer IP_1
Set transform-set trset1
match address ACL_1
output

map CRNAME 2 ipsec-isakmp crypto
Description - VPN - 2
defined peer IP_1
Set transform-set trset2
match address ACL_2
output

interface FastEthernet0/0
Description - outdoors-
card crypto CRNAME
output

For an EasyVPN (or any other dynamic encryption card), you can use this example:

crypto dynamic-map DYNMAP 1
transform-set Set feat
market arriere-route
output

card crypto crmap 3 - isakmp dynamic ipsec DYNMAP

And example for DmVPN clouds to the 1 Router 2:

Crypto ipsec transform-set esp-3des esp-sha-hmac trset_1

output
Crypto ipsec transform-set esp-3des esp-md5-hmac trset_2

I make a connection to the Dominican Republic (10.15.101.1) and tunnel comes however, there are a few problems with IPSEC. When I remove tunnel protection beginning of things work properly and I can receive responses of ping from both ends which means PNDH / config DMVPN is perfect. The problem with IPSEC (phase 2), it's that I want to connect 10.15.101.1 (DR) and branch (10.152.1.202).

When I check crypto ipsec to show his I see duplicate proxy identity i.e. 10.152.1.202 - 10.15.101.1 tunnel (shown above in quotation) 220 and again in tunnel of 230. Very well to make things work it should only appear in the config of Tunnel 230. When I stop 220 tunnel proxy identity goes far from 220 and only the left one is taken from Tunnel 230 (the right one) after he starts to work properly, but when the two tunnels are entered again duplicate would come to the top and the other end (tunnel), which is the 192.168.230.x acquired through 10.15.101.1, I can not ping.

Would it be because of the bug in the IOS? Note that in above config (220 tunnel that points to *) I put ip PNDH card 192.168.220.1 10.16.101.1 which means that I would receive from only in crypto ipsec (for tunnel 220) connection to 10.16.101.1 and not 10.15.101.1.

Hmmmm, phase 1 DMVPN (which uses a point next to speak) does not require not shared ;-)

It's the only multipoint interface problem.

Happy WLL in any case, it has worked.

ASA 5505 9.1 Unable to ping inside the IPSec VPN network

To give some background that the asa has been reloaded and upgranded from 8.2 to 9.1. I am able to connect to vpn, but unable to reach anything inside, including of the asa. I didn't unfortunately not much experience with 8.3 +, but I thought that I had nat made appropriately. Nothing else is currently configured for the asa, as it's just an asa test currently, so I could of just missed something odvious.

Hello

To be honest, I can't see anything in the configuration that should be a problem.

Your NAT settings seem to be correct.

You have the global setting of "sysopt connection permit - vpn" who does not appear in this form in the CLI configuration. This configuration means essentially that the SAA would allow traffic from a VPN connection to work around interface ACL of the interface when the VPN connection is completed (outside)

Your ACL Split Tunnel is also correct.

You might connect with VPN Client and run a continuous ICMP to a host of LAN and provide an output of the following command after a the ICMP has run a few seconds

Crypto ipsec to show his

Should see the counters of VPN.

You can also try adding

management-access inside

This should allowed you to the 'internal' to the ASA IP ICMP and also manage ASA through the VPN connection by using the 'internal' the IP address provided you have enabled it. But for this you need to change the configuration of "nat" in this

NAT (inside, outside) static source inside obj obj-indoor destination static obj - vpn vpn-obj-research route

Hope this helps

QNS vpn IPsec

Hello

I have 2 questions about vpn IPsec

I have an asa, vpn ipsec (l2l) running on a remote site with 192.168.0.0/24 network

1 > I can ping 192.168.0.1 but not 192.168.0.111. I had observed "Recv errors" whenever I have ping to 192.168.0.111.

I had observed recevied errors of "crypto ipsec to show his" exit; but not because the tunnel to reconnect (after timeout) and w/o any changes made to the configuration.

What could be the cause and how can I fix just in case where the returned errors? I can't find much info on "recv errors."

2 > I understand there are 2 acl required for a vpn ipsec typical; 1 for no NAT, 1 correspondence address card crypto

can I implement an acl to allow tcp 3389 only from the remote network on my local network on the asa?

Thank you

cash

Salvation of cash,

There is not a lot we can do here in what concerns this isuse.

You can talk to your service provider and see if they do not modify the packets somehow.

Also ask them to check for any problem on the circuit.

See you soon,.

Nash.
