• Adding a pix 501 VPN 2

  Hello.. I am beginner in this kind of things cisco...

  I'm trying to set up multiple VPN on a Cisco PIX 501 firewall with routers Linksys BEFVP41...

  Since not very familiar with the CLI, I use the PDM utility and it was very easy for the first... Unfortunately, I get this error when I try to add the second VPN using the VPN Wizard:

  Outside_map map (ERR) crypto set peer 200.20.10.3

  WARNING: This encryption card is incomplete

  Hi garcia

  for each vpn/peer, you need to a separate instance of crypto card, the card will have the same name, but different sequence... numbers one map encryption can be attributed to an interface, but you can have several instance of cards inside a main...

  for configuration, you can go through the URL below... It has all the details on IPSEC config:

• NAT Traversal on site to site VPN pix

  I don't think it's possible to implement NAT traversal between a site to IPSEC VPN using ESP tunnels?

  Our ISP to the remote end will provide only a public IP address and which is attributed to their router...

  Sites are using pre-shared keys and IKE

  for example...

  LAN-PIX1-ISPROUTER-INTERNET-ISPPATROUTER-PIX2-LAN

  I have attached the card encryption for more info

  Thanks in advance...

  I guess that NAT - T is most commonly used in a customer VPN environment, but I'm sure that its not limited to this type of connection.

  I just set up a VPN this morning with the help of a customer on a router running 12.2.15T and tested connection with NAT - T works very well by using IP addresses.

  NAT - T enabled by a NAT detection process, and there is that to protect the ESP of a change should work in both environments.

  I'll have a go in my lab, see if I can implement and check it.

  However by going to the original post, you say that only one address is available from the ISP, it is on the router for pix link?

  Where are the limits of NAT, I expect to be in the PIX, but it must be a public IP address on you interfaces also. You can then use the external address as endpoints IPSec, don't need NAT - T in any case.

• Cisco VPN Client Authentication - PIX 515E-UR

  Hi all

  I need your expert help on the following issues I have:

  1. I would like to create more than 1 client VPN on my PIX-515E groups. This is so that I can give a different part of the internal network access to different type of VPN connection. For example, I want a group to have no XAUTH, while the other group must use RADIUS XAUTH. Is it possible for me to do this? I see the PIX automatically enable RADIUS on both groups of VPN clients.

  2. the RADIUS server is a Microsoft ISA with IAS server and it is located on the PIX inside interface. The VPN endpoint is external interface of the PIX. Is there a problem with this Setup? Do I need to have the RADIUS server that is located on the external interface?

  3 can. what command I use to debug RADIUS authentication?

  Thanks in advance for your help.

  Hi vincent,.

  (1) you can use the vpngroup *-authentication server ipaddress to specify the IP address of the Radius Server on a particular group... If you do not specify this, the authentication of the user is made locally... also check for vpngroup * order of user authentication

  (2) there should be no problem with the installation of your... should work fine... If the RADIUS is outdoors, it is subject to many attacks... so have it inside...

  (3) use the "RADIUS session debug" or "debug aaa authentication..."

  I hope this helps... all the best... the rate of responses if found useful

• Client VPN on PIX needs to access DMZ

  VPN clients 3.5 ending PIX 6.X cannot access hosts on a PIX DMZ interface. Journal reports of error that there is no 'translation group available outside' for the subnet of the VPN Client (from the vpngroup pool).

  I should add the VPN client subnet to a nat (outside) device?

  Can I add it to the nat inside?

  Can I just add static to the DMZ hosts within the subnet interface because VPN clients can access the inside hosts?

  (I have the subnets in the nat 0 sheep ACL)

  Thanks and greetings

  JT

  You'll need to add is nat 0. You say in your () you have an acl sheep, for the perimeter network or the inside interface? You use the same access list to the sheep inside and dmz? You should separate if you use separate access list. Is your pool of client on a different subnet than your home network and dmz? It must be something like this:

  Customer IP local pool 192.168.1.1 - 192.168.1.254

  IP, add inside 10.10.10.1 255.255.255.0

  Add 10.10.20.1 dmz IP 255.255.255.0

  access-list sheep by 10.10.10.0 ip 255.255.255.0 192.168.1.0 255.255.255.0

  nonatdmz list of access by IP 10.10.20.0 255.255.255.0 192.168.1.0 255.255.255.0

  NAT (inside) 0 access-list sheep

  NAT (dmz) 0-list of access nonatdmz

  If this is correct then clear x, wr mem, reload. I hope this helps.

  PS

  If he did not, only can recommend the upgrade your client and pix because that is exactly how it should look, and if its does not work you are facing an additional feature you want.

• 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.

• 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).

• Remote administration of a PIX running as a VPN client

  Hello

  I have a setup where a PIX501 works as a VPN client upward against my central VPN3000 concentrator (LAN-2-LAN with NAT - T mode).

  External interface of the pix is behind a firewall managed by ISP to the remote end, and get it via DHCP IP address.

  So far so good. This configuration works hotel.

  The problem is that I can't ssh/telnet to the external interface of the PIX due to this configuration.

  Would it not possible to ssh/telnet to the remote pix _inside_ interface?

  I guess stuff NAT Bennett, but I can't make it work.

  Any ideas?

  (: O) Mikkle

  This is possible by commands:

  management-access inside

  It works very well as I have used both inside interface is included in all the crypto config

• 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

• 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.

• site2site distance-VPN and access-PIX - no way?

  I have,

  I have a problem wrt site2site & VPN remote access on a PIX:

  My setup is as follows: PIX (6.3) puts an end to two a site2-site VPN and also should the remote access service clients using the client VPN Cisco (4.0.x).

  The problem is with remote access VPN clients, obtain an IP address on their VPN interface, but customers cannot reach anything. (Please note that the site2site VPN runs without problem)

  To be precise (see config-excerpts below):

  The customer, who has 212.138.109.20 as its IP address gets an IP 10.0.100.1 on his card-VPN which comes from the "vpnpool of the pool.

  configured on the PIX. This customer relationships to reach servers on interface 'inside' of the PIX as 10.0.1.28.

  However, the client cannot achieve * nothing *-a server on the inside or anything like that (e.g. Internet) outside!

  Using Ethereal traces, I discovered that the packets arrive inside interface coming 10.0.100.1 (IP address of the)

  VPN - client). I also see the response from the server (10.0.1.28) to 10.0.100.1. However for some reason any package does not thanks to

  the PIX to the customer. PIX-newspapers also show packets to and from the VPN client to the inside interface - and * no. * drops. So to my knowledge the packets from server to the VPN client really should be done through the PIX.

  I have attached the following as separate files:

  (o) the parts of the PIX config

  (o) packets showing PIX-log between the VPN client and the server (s) on the interface inside

  (o) ethereal-trace done inside the watch interface also packets between VPN client and server (s)

  I have really scratched my head for a while on this one, tested a lot of things, but I really don't know what could be a problem with my

  config.

  After all, it really should be possible to run site2site - and on the same PIX VPN remote access, shouldn't it?

  Thank you very much in advance for your help,.

  I think that your problem is in your ACL and your crypto card:

  access-list 101 permit ip 10.0.1.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 101 permit ip 10.0.0.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 101 permit ip 10.0.3.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 101 permit ip 10.0.1.0 255.255.255.0 10.0.100.0 255.255.255.0

  correspondence address 1 card crypto loc2rem 101

  This means that this map correspond to these addresses. But your dynamic map is one that must match 10.0.100.0, 10.0.1.0 traffic because your pool local ip is 10.0.100.x. I think what is happening is that the return traffic from the lan to vpn clients trying to get out of the static tunnel, which probably does not exist (for the netblocks - you probably have a security association for each pair of netblocks, but not for vpn clients) and so do not.

  I would recommend adding these lines:

  access-list 105 allow ip 10.0.1.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 105 allow ip 10.0.0.0 255.255.255.0 10.0.2.0 255.255.255.0

  access-list 105 permit 10.0.3.0 ip 255.255.255.0 10.0.2.0 255.255.255.0

  no correspondence address 1 card crypto loc2rem 101

  correspondence address 1 card crypto loc2rem 105

  Then reapply:
