Number of VPN clients behind a PIX 501, restriction?

• 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.

• Cisco VPN Client behind PIX 515E,-> VPN concentrator

  I'm trying to configure a client as follows:

  The user is running Cisco VPN Client 4.0. They are behind a 6.1 PIX 515E (4), and I need to connect to a VPN concentrator located outside of our network. We use PAT for address translation. As far as I know, to allow ipsec through Firewall 1 tunnel, I need to upgrade the pix to 6.3 and activate "fixup protocol esp-ike.

  Is there another way to do this? I am also curious to know how much more easy/better this will work if we were dealing with pptp.

  You don't necessarily need to fixup protocol esp-ike active. The remote Hub there encapsulation NAT - T enabled so that clients behind the NAT can run?

• VPN client behind ok asa pix but no asa

  Hi all

  I was faced with a newly installed asa5505 couple. We can use the vpnclient in devices, but not behind another asa. Behind the asa same we can vpn for previous installations of pix. But when we go to other asa installs, we get the regular creation of translation failed for protocol 50.

  We have activated, isakmp, nat-traversal, udp 4500 and udp 10000. If the fault is at the other end, even if the error shows in this end?

  Anyone who is willing to help me with this?

  see you soon / Peter

  You do not allow protocol 50 - ESP through the firewall. The remote end VPN are trying to create a VPN in mode 'Hand' is not "Aggressive" mode as VPN clients.

  Add the below and test again: -.

  permit for outside_access_in to access extensive list of 6 esp a whole line

• Several VPN clients behind PIX

  Multiple users in our company have establish a VPN client connection to a VPN Internet gateway. The connection must go through our PIX. I already active correction for esp - ike Protocol and this allows a user to get out. When following users try to configure a VPN connection to the VPN gateway on the internet, the following syslog error appears:

  3 PIX-305006%: failed to create translation portmap for udp src inside:192.168.0.102/500 dst outside:1x5.x17.x54.x10/500

  It seems to me that the PIX only supports an outbound VPN client connection at the time. Is this true?

  When I perform a clear xlate, first user disconnects, but new users is able to establish a VPN connection.

  Kind regards

  Tom

  That's right, Tom - in the release notes for 6.3 (1), the PAT for ESP section says "PIX Firewall version 6.3 provides protocol PAT IP 50 capacity to support unique outbound IPSec user."

  If you have enough public IP addresses and the remote VPN gateway supports PPTP, then a means to achieve multiple outbound VPN connections would be to set up a separate pool of the NAT for users who require outbound access and assign internal IP addresses of those users to use these addresses.

  Having had just a quick look around, if PPTP is an option, then the PPTP PAT 6.3 support can help.

• Number of VPN client

  Hello

  Im trying to set up my friends firewall to accept connections vpn client software to remote sites. I applied a configuration to a previous case, I did, but this time, when the client tries to connect, it comes to the point of "Securing communications channel" and goes no further. Ive attached the configuration of the pix and some debug and show the result of the command.

  Also, if I wanted to limit the remote client using only the port to a single server, how I would approach this? In my case, I don't want to give the customer access to a single server on the DMZ with the port 25.

  Thank you.

  To limit access to only specific server and client vpn port, follow these steps:

  1 allow customer traffic ipsec should be handled by an acl applied to the external interface by running this command in global configuration mode:

  No ipsec sysopt connection permit

  2. add these statements to acl 2, which is applied to the external interface:

  access-list 2 permit tcp 172.16.1.0 255.255.255.0 host x eq 25

  Notes:

  ACL 2 has an explicit deny ip everything no matter which line which should be removed and added back after all the acl changes are made, otherwise he would block want you want to allow.

  You may need to enable vpn clients to connect to your dns or wins servers too, unless they will respond to your e-mail address in server ip instead of the host name.

  Which version of the client vpn do you use and what OS it runs? You may need to add an isakmp policy which has a duration of less than 86400 seconds to get the client to connect.

  Let me know what you find.

• How to configure to allow users in my web server behind a PIX 501

  I have 1 web server, 4 web hosting sites. IP addresses are like:

  the area of the web server itself: 192.168.111.11

  1 web site on this box has IP 192.168.111.101

  2nd ............................................ 192.168.111.102

  3rd ............................................. 192.168.111.103

  4th ............................................. 192.168.111.104

  My OUTSIDE interface (say) 205.200.20.5

  My INSIDE interface has 192.168.111.1

  I want to leave the outside web traffic in my web server box that hosts 4 sites. I only let people with HTTP and HTTPS.

  How should I do and for purposes of flexibility, say also tomorrow I want to host my site on a different web server #3 but always with the same IP address, can I selectively route certain web traffic to the boxes in different web server?

  Also, I want to open another port, say, 8080 for administrative purposes. Can I route HTTP or HTTPS, addressed to some port # to the Web server also?

  You will need to create static port mapped, but if you have only the external IP address a people can connect to, they will need to connect to a specific port in the URL to differentiate which internal web server, they really want to go.

  For example:

  > static (inside, outside) tcp 205.200.20.5 80 192.168.111.101 80 netmask 255.255.255.255

  > static (inside, outside) tcp 205.200.20.5 81 192.168.111.102 80 netmask 255.255.255.255

  > static (inside, outside) tcp 205.200.20.5 82 192.168.111.103 80 netmask 255.255.255.255

  > static (inside, outside) tcp 205.200.20.5 80 83 192.168.111.104 netmask 255.255.255.255

  maps of connections to 205.200.20.5 on port 80 through to port 80 on 192.168.111.101. Connections inbound to port 81 will be mapped through to port 80 on 192.168.111.102. Connections incoming on port 82 will be mapped through to port 80 on 192.168.111.103 and so on.

  You cannot map just all incoming traffic on port 80 to 4 different internal web servers, cause how the PIX will know which send traffic to.

  To allow access, as well as the static shown bove, you must:

  > list of allowed inbound tcp access any host 205.200.20.5 eq 80

  > list of allowed inbound tcp access any host 205.200.20.5 eq 81

  > list of allowed inbound tcp access any host 205.200.20.5 eq 82

  > list of allowed inbound tcp access any host 205.200.20.5 eq 83

  > list of allowed inbound tcp access any host 205.200.20.5 eq 443

  > interface entering outside acess group

  HTTPS is also going to be a problem, to do the same on HTTP, you need to use different ports to differentiate what specific internal web server that you want to that they go (and allow these ports in your "incoming" ACL above).

  To port 8080, just follow these steps:

  > static (inside, outside) 205.200.20.5 tcp 8080 192.168.111.10x 8080 netmask 255.255.255.255

  > list of allowed inbound tcp access any host 205.200.20.5 port 8080

  As you can probably guess, this won't work very well if you have only one external IP address, because users will not know to specify a specific port number so that they get through an internal host specific. You may have a single external address for each web server internal to this work in reality.

• PIX 501 - VPN - based

  Hello

  I am considering the implementation of a vpn pptp on win2k server behind a pix 501 firewall (+ nat) with only 1 static IP address. I will also have to have at least 2-3 Terminal Server client connected simultaneously.

  The Terminal Server service will pass through vpn tunnel.

  Can this be achieved? A local Tech told me that I need at least 2 IP addresses.

  Thank you

  Mike

  For Terminal Server services, you can do it with just an IP address that is assigned to the external interface of the PIX, just create a static mapped port to port 3389 thru peripheral inward.

  For PPTP, you must however an IP address separate, different from that assigned to the PIX outside the int. This is because PPTP uses two TCP/1723 and GRE protocols. You can create a static mapped ports for TCP/1723 through the PPTP server, but you can't do it for the GRE. This is because GRE is not a TCP/UDP protocol, it is located just above IP and has therefore no port number to map through. You need an IP address unique address and card. You config should look like this:

  list of allowed inbound tcp access any host 200.1.1.1 eq 1723

  list of allowed incoming access will any host 200.1.1.1

  Access-group interface incoming outside

  public static 200.1.1.1 (indoor, outdoor) 10.1.1.1 netmask 255.255.255.255

  where 200.1.1.1 is your second (different from the PIX off int) routable IP address 10.1.1.1 is your PPTP server inside

  If you only want to use an IP address, why don't the PIX not set itself up as a PPTP server and put an end to your connections on this. The PPTP client end simply on the PIX outside IP address, and you will not need all the others.

  See http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080143a5d.shtml for more details.

  My internal network connected to the PIX is 192.168.1.1 - 192.168.1.33 and the VPN ip pool is 192.168.2.1 - 192.168.2.5

  "isakmp nat-traversal 20" can do the trick.

• 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

  To remedy the situation even and a list of valid to add this encryption card

  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:

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

• Enable syslog server behind the PIX

  Could someone tell me a config that allows a server syslog (Kiwi syslog) to get behind the PIX syslogs. I have a 2K with the KIWI syslog server behind a PIX 501.

  I have the static command, the access group and the access-list:

  public static 192.104.109.92 (Interior, exterior) 192.168.15.200 netmask 255.255.255.255 0 0

  Access-group local_server in external interface

  local_server list access permit udp any host 192.104.109.92 eq syslog

  Man, I can't understand it.

  Thanks for any help

  You could:

  1. make a capture of port syslog traffic directed to the syslog server.

  2 Terminal monitor - deny traffic showed clearly when I had not set up the firewall to forward the traffic. (Note: attention on busy firewall)

  3 netstat - a on the syslog server

  4. If you allow, you should be able to portscan the server on port of syslog by your firewall.

  5. is your syslog capture created file? It is not created if the service never started.

  6 - is the service running in the system context or perhaps another account that doesn't have the correct rights?

  The answers seem to indicate a service not started that seemed likely. What you describe happened to me when I had the demon also version; I went to service version and the problem has been resolved (once I opened the port.)

  I love the kiwi syslog. I use with Snare and BacklogIIS and receive alerts within 60 seconds to my mailbox when something bad happens. It always fools of my end users out when I call them with the problem solved when they seek always my number report the problem.

• The CBAC & VPN Client

  I use soft Cisco VPN client behind a Cisco CCCB router running. What are the ports must be opened to allow the client VPN working properly?

  I am currently using:

  allow an esp

  allow udp any any eq isakmp

  These are necessary, but you may also need to open UDP 10000 to support NAT - T if IPSec must cross a NAT border along its way.

  You'll also need allow beach access VPN client address to the IP address ranges whatever they are to be used in common. This is because packages through the ACL twice, once encrypted using ESP and ISAKMP, there not yet encrypted.

  So, if the VPN client has a range of pool to say 10.1.1.0/24 and his contact only the acl 10.2.0.0/16 subnet would look like:

  IP access-group extended VPNACCESS

  allow an esp

  allow udp any any eq isakmp

  permit IP 10.1.1.0 0.0.0.255 10.2.0.0 0.0.255.255

• ASA5505 - Maximum VPN Clients

  Hey all, any idea what the maximum number of VPN clients can connect to the ASA5505? It runs to the base image. Thank you, robert.

  The devices allowed for this platform:

  The maximum physical Interfaces: 8

  VLAN: 3, restricted DMZ

  Internal hosts: unlimited

  Failover: disabled

  VPN - A: enabled

  VPN-3DES-AES: enabled

  Peer VPN: 10

  WebVPN peers: 2

  Double ISP: disabled

  Junction ports VLAN: 0

  This platform includes a basic license.

  Yes, apparently your interpretation is correct. If you have a race box you lab this place and see what happens after the grid of th 11' client attempted to connect. Most likely the client wil see an error message.

  Please rate if useful.
