ISAKMP PIX

I have enabled debugging for isakmp crypto on my 515 and message every 20 seconds.

crypto_isakmp_process_block:src:207.47.138.190, dest: 'my address' spt:4500 dpt:4500

ISAKMP (0): processing NOTIFY payload Protocol 40500 1

SPI 0, message ID = 1302825637

to return to the State is IKMP_NO_ERR_NO_TRANS

The output interpreter says the following...

INFO: This device has registered the message of the IKMP_NO_ERR_NO_TRANS newspaper.

This message indicates that ISAKMP had no error and there is no need of retransmission.

The purpose of this message is purely informational.

The problem is, I have no reference to 207.47.138.190 in my config. What does this mean really? Certain someone tries to establish a VPN with my PIX?

Thank you

Bruno

The 207.47.138.190 is the address that tries to open the ISAKMP negotiating with you. You have a dynamic encryption card configured? This could explain why you don't have any reference to this specific address in config.

Error message from Debug ISAKMP tunnel on PIX

I configured a Linksys VPN router and a PIX as site to site.

When I run the cry of debugging on the PIX commands, I always get the following message is displayed:

«ISAKMP (0): Config Mode Request retransmission...» »

I searched the site of Cisco and the Web and can not find something definitive as to what is causing my error.

When I do a ' sh isa his ' on the PIX, I get the following:

State = OAK_CONF_ADDR, but I can't reference that is.

What are these debugging output tell me?

When the configuration of IPSec with other than Cisco devices, always cut xauth (add the No.-xauth command)

Connectivity random Cisco Pix 501

Hello. I'm having some trouble with my CISCO PIX 501 Setup.

A few months I started having random disconnects on my network (from inside to outside). The machines can ping the DC or the Pix, but impossible to surf the internet. The only way to make them go outside is a reboot of Pix.

My configuration is:

Do you have any advice? I don't get what's wrong with my setup.

My DC is 192.168.100.2 and the network mask is 255.255.255.0

The network configuration is configured to set the IP of the gateway to 192.168.100.1 (i.e. the PIX 501).

I have about 50 + peers on the internal network.

Any help is apprecciate.

PIX PIX VPN - error log

I created a VPN between our PIX and PIX customers but receives the following error message when I try to activate tunnnel. I checked the ACL on both ends. Any ideas?

ISADB: Reaper checking HIS 0x80da9618, id_conn = 0IPSEC (sa_initiate): ACL = deny;

No its created

IPSec (sa_initiate): ACL = deny; No its created

IPSec (sa_initiate): ACL = deny; No its created

IPSec (sa_initiate): ACL = deny; No its created

I've seen a few times. Usually remove the interface of the card encryption and re - apply solves it, sometimes it is necessary to remove the card encryption and the "enable isakmp outside" and put them both back in.

This message is also sometimes to do with something wrong in the configuration, in order to double-check your ACL and your transformation games, etc.

Win2K NAT would be from 1650 to a PIX 515 - does not

Hello

:

I have a working VPN config on my 515 (6.2.2) and can tunnel from one host with a valid external IP without any problem. But, with a NAT would be customer, nothing seems to work.

I use RADIUS to authenticate after using a password for the group. Here is the sequence of events.

(1) client machine as a 10.0.0.1 address, NAT had a public address to come into the port of 'outside '.

(2) the client connects, the user enters GANYMEDE password and is connected.

(3) the user tries to browse any service and can not.

(4) if the user switches DNS to an external server, the portion of the split tunnel internet works fine but inside is still broken.

(5) clients with static IP addresses that are publicly routable connect and can perform all internal and external activities of split tunnel.

Excerpts from config. I'm doing something wrong?

You do not have something wrong. The problem is that NAT (NAT actually PAT, port) and IPSec is not working very well, and many features PAT can PAT IPSec traffic to all (PIX included until version 6.3).

The problem is that PAT depends on using the port number TCP or UDP source as a way to differentiate between sessions, because they are all PAT would be from the same source IP address. However IPSec (ESP at least), tracks right on top of IP, in other words, it is NOT a TCP or UDP protocol, and therefore has no associated port number. It breaks most of the PAT devices.

The reason for which you can build your tunnel initially, it is that it is all done by ISAKMP, which is a UDP protocol, which can be PAT would be fine. Once the tunnel is built however, all encrypted data are sent by packs of ESP, which as I said, is not a TCP or UDP protocol.

Trnalsations NAT static work cause they do not rely on the use of the port number, they just change the address of the source that works very well with ESP.

There is not much you can do about it. If you were closing the VPN into a VPN3000 concentrator, it has a feature called IPSec through NAT, which encapsulates all ESP packets in a UDP packet, which can then be PAT would be properly. The PIX, unfortunately, doesn't have this feature. The only solution is to get a NAT device that manages properly the IPSEc. Surprisingly, some of the less expensive devices on the market handle it, but you should check with each manufacturer to be sure.

EZVPN - PIX to PIX

This is perhaps a silly question, but I am at a loss to see what the problem is.

I have a 515 on my site and am trying to install a few small 501 office across the country.

Each office can connect and establish a tunnel when I configure use EZ and I a setting up split-tunnel to pass to the Internet or to me every time.

If for some reason, I have to restart my PIX or my T1 goes down, they lose the tunnel (of course), but they lose also any Internet connection they have. The only way to get them reconnected to the world must go and uncheck the box "use the EZVPN."

At the end of the day, I don't want to then lose all connectivity when / if I get off.

What I forget?

Thanks in advance.

VPN to Pix problem

It seems that I have problems similar to many others in the connection of remote clients to a PIX 515E.

Currently, I have tried both the client VPN Cisco 3.6 and 4.03 without success. Users are authenticated very well and the customer, you can see that their assigned an address etc but they are unable to access the internal network. The crypto ipsec his watch HS no encrypted traffic has affected the Pix as its...

within the State of the customer etc., it shows that packets are encrypted so I'm at a bit of a loss.

I have also a problem with pptp connections - this seems to differ between the BONES on the client but Win2K machines can connect and get checked etc but again failed to connect within the networks. These could be linked?

My current config is: (change of address, etc.)

If you do not see decrypts side Pix while my thoughts are (for IPSEC) ESP and GRE (for PPTP) do not get to your Pix (blocks perhaps of ISP or other devices).

If you do a "capture" of the packets on the external interface you see all traffic ESP or GRE? Where the customer? If this isn't the case, dialup is ESP or permitted GRE?

SonicWall VPN PIX - does not, could someone help?

Hi all

I'm trying to set up an a 506th PIX VPN tunnel (firmware 6.3 (2)), a firewall SonicWall Pro. It does not at the moment. Phase 1 is ok but the phase 2 is not, the VPN tunnel has not been established, and the security association is removed after a minute or two. I enclose below the PIX config and an attempt to create VPN tunnel debugging output (slightly modified and cut for reasons of confidentiality). The PIX already has other two VPN configured which work perfectly.

I would be very grateful to anyone who could help me answer the following questions about this VPN configuration:

1. to debug output, which means the next?

ISAKMP (0): retransmission of the phase 2 (0/0)... mess_id 0xafc08a94

crypto_isakmp_process_block:src:remotevpnpeer, dest:vpnpix1 - dpt:500 e0 spt:500

ISAKMP: error msg not encrypted

2. in the config, I don't know if the 3 static controls are necessary and how it might interact... What do you think?

3. in what order things happen in the PIX when traffic is from the local network to remote network by VPN? What is NAT then treatment then setting up VPN to access list? or or treatment, then NAT and VPN to access list? or another possibility?

4. How can I get it work?

Thank you very much in advance for any help provided,

A.G.

This indicates the PIX not NAT IPSec traffic. NAT happens BEFORE IPSec in the PIX, so if you the traffic IPSec nat it will never match your crypto access list and will not be encrypted.

This, however, should not stop the tunnel of Phase 2 of the course of construction, they would stop flowing above the tunnel, traffic, so you still have a problem somewhere. What I'm guessing, is that the Sonicwall (SW) has a different encryption-defined list access, it must be the EXACT OPPOSITE of what is configured on the PIX. In other words, the SW should be encrypting the traffic of "remotevpnLAN-24" "intranet/8", make sure that the subnet mask ar ETHE same too. "

To answer your questions:

1. it simply means that the PIX has not received a response and is to retransmit the last ISAKMP packet. The process_block simply means that the PIX has dropped a package that was to be encrypted because the IPSec tunnel has not been built. If you get the tunnel built, these messages will disappear.

2. the 3 first static does not appear to be linked to the tunnel IPSec, if they are simply to access a server inside, then they will not affect this VPN tunnel. The last of them should be deleted, as I already said.

3. for traffic initiated from inside the PIX, the order is incoming ACL, then NAT, IPSec processing. That's why your OUTGOING ACL must allow traffic first, then your NAT 0 statement refuses to be NAT had, then the encryption function is the traffic and the number.

4 do what I said above :-)

If you still have no luck, re - run debugs, but initiate traffic behind the Sonicwall, in this way the Sonicwall will try and debug of build that the tunnel and you will get more information on the PIX. Mainly, we'll see what traffic model the SonicWall is configured to encrypt (you don't see if the PIX initiates the tunnel).

PIX-Sonicwall Site-to-Site and Cisco VPN Client

I have a firewall 506th PIX with a VPN site-to site for a firewall Sonicwall 330 Pro which works perfectly. I would like to add the functionality of remote users connecting to the network using the client VPN from Cisco PIX. I'm under the question of having only a single card encryption applied to the external interface. I need the feature to have the tunnel between the site to site VPN can be undertaken on other, so I can't use a dynamic encryption card. Does anyone have suggestions or knowledge on how to achieve this?

Thank you.

You don't need to add another card encryption to the external interface. You simply add customer information to your existing card for example:

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

YOURMAP 10 ipsec-isakmp crypto map

card crypto YOURMAP 10 corresponds to 100 address

card crypto YOURMAP 10 set counterpart x.x.x.x

crypto YOURMAP 10 the transform-set YOURSET value card

set of 10 CUSTOMERS crypto dynamic-map transform-set YOURSET

card crypto YOURMAP 90-isakmp dynamic ipsec CLIENTS

IPSec over TCP on PIX 501F to the catalog

Hello

Is there a way I can configure IPSec over TCP as default configuration in the PIX firewall. I'm under 6.3

The PIX does not support IPsec over TCP. It doesn't support NAT - T, which is IPSec over UDP/4500, which houses also of the Cisco VPN client. Just add the following command on the PIX:

ISAKMP nat-traversal

The PIX and VPN client auto-négociera if necessary IPSec encapsulation. See http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/gl.htm#wp1027312 for more details.

Hello Krishna

If possible and feasible to try and downgrade the IOS 12.3 (9) to a low-level code as 12.3.6. But, make sure that the image is a single k9 and supports VPN. Also upgrade the pix to 6.3.3.

Assuming that the keys are the same, your configs find ok. Him debugs it seems its not able to pass from the phase 1 properly

could contribute to modify the code.

I don't see anywhere in the documentation where it is mentioned, so I don't know where to go from here.

Config Pix: is attached.

Any advice would be great.

Michael

Something else... According to the clearance for the cisco vpn client 3.6 sha is no longer supported:

The VPN Client is always supported DES/MD5; However, support for SHA/DES is no longer available. Because of the latter, the Clients VPN version 3.6 can not connect to any device central-site group that is configured for (or offer) DES/SHA. The VPN Client must either connect to another group or for device central-site administrator must change the configuration of DES/SHA DES/MD5 or another supported configuration. The VPN Client Administrator's Guide lists all the encryption supported configurations *.

It would be a good thing to also change your transformation the value:

Crypto ipsec transform-set esp - esp-md5-hmac NEWTS

Change the ISAKMP keys

I have a Pix 506 running v6.1 (2) that I need to change the ISAKMP key on. When I entered the new type-error telling me that there is already a key, but I can't find how to clear the existing key. Any suggestion is appreciated. -Pete

The VPN client VPN connection behind other PIX PIX

I have the following problem:

I wanted to establish the VPN connection the client VPN to PIX on GPRS / 3G, but I didn t have a bit of luck with PIX IOS version 6.2 (2).

So I upgraded PIX to 6.3 (4) to use NAT - T and VPN client to version 4.0.5

I have configured PIX with NAT-T(isakmp nat-traversal 20), but I still had a chance, he would not go through the 1st phase. As soon as I took nat-traversal isakmp off he started working, and we can connect to our servers.

Now, I want to connect to the VPN client behind PIX to our customer PIX network. VPN connection implements without problem, but we can not access the servers. If I configure NAT - T on the two PIX, or only on the customer PIX or only on our PIX, no VPN connection at all.

If I have to connect VPN client behind PIX to the customer's network and you try to PING DNS server for example, on our PIX, I have following error:

305006: failed to create of portmap for domestic 50 CBC protocol translation: dst outside:194.x.x.x 10.10.1.x

194.x.x.x is our customer s address IP PIX

I understand that somewhere access list is missing, but I can not understand.

Of course, I can configure VPN site to site, but we have few customers and take us over their servers, so it'd just connect behind PIX VPN and client connection s server, instead of the first dial-in and then establish a VPN connection.

Can you please help me?

Thank you in advan

The following is extracted from ASK THE DISCUSSION FORUM of EXPERTS with Glenn Fullage of Cisco.

I've cut and pasted here for you to read, I think that the problem mentioned below:

Question:

Hi Glenn,.

Following is possible?

I have the vpn client on my PC, my LAN is protected by a pix. I can launch the vpn client to connect to remote pix. Authenticates the vpn client and the remote pix makes my PC with the assigned ip appropriate to its pool of ip address.

The problem that I am facing is that I can not anything across the pix remote ping from my PC which is behind my pix. Can you please guide me what I have to do to make this work, if it is possible?

My PC has a static ip address assigned with the default gateway appropriate pointing to my s pix inside interface.

Thank you very much for any help provided in advance.

Response from Glenn:

First of all, make sure that the VPN connection works correctly when the remote PC is NOT behind a PIX. If that works fine, but then breaks when put behind a PIX, it is probably that the PIX is PAT, which usually breaks IPSec. Add the following command on your PIX VPN client is behind:

fixup protocol esp-ike

See http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/df.htm#wp1067379 for more details.

If it still has issues, you can turn on NAT - T on the remote PIX that ends the VPN, the client and the remote PIX must encapsulate then all IPSec in UDP packets that your PIX will be able to PA correctly. Add the following command on the remote PIX:

ISAKMP nat-traversal

See http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_63/cmdref/gl.htm#wp1027312 for more details.

NAT - T is a standard for the encapsulation of the UDP packets inot IETF IPSec packets.

ESP IPSec (Protocol that use your encrypted data packets) is an IP Protocol, it is located just above IP, rather than being a TCP or UDP protocol. For this reason, it has no TCP/UDP port number.

A lot of features that make the translation of address of Port (PAT) rely on a single to PAT TCP/UDP source port number ' ing. Because all traffic is PAT would be at the same source address, must be certain uniqueness to each of its sessions, and most devices use the port number TCP/UDP source for this. Because IPSec doesn't have one, many features PAT fail to PAT it properly or at all, and the data transfer fails.

NAT - T is enabled on both devices of the range, they will determine during the construction of the tunnel there is a PAT/NAT device between them, and if they detect that there is, they automatically encapsulate every IPSec packets in UDP packets with a port number of 4500. Because there is now a port number, PAT devices are able to PAT it correctly and the traffic goes normally.

Hope that helps.
