• Several outbound VPN connections behind PIX-515E

  I will take a PIX-515E off-site for a provision of access internet location. I have several people behind this PIX, who will have to return to the same Office VPN. One person can VPN through the PIX very well, but if someone else tries to VPN they cannot. Once the first person has disconnected for 10 minutes, then the next person can connect. I activated the NAT - T and added fixup protocol esp-ike. What can I do it wrong? Thank you.

  fixup protocol esp-ike - allows PAT to (ESP), one tunnel.

  Please remove this correction.

  If the remote site has NAT - T enabled, then you should be able to use NAT - T and more than 1 user should be able to use behind the PIX VPN client.

  See you soon

• VPN connected to Pix but no Internet access after login

  Hello

  We just changed on our firewall in a Pix 515. The VPN Client (4.6) was set up and remote users can connect ok, and authenticate with IAS in Windows. However, once that they connect to the VPN they can't surf the internet. Our support company say that this is impossible because it can cause the usurpation. Is - this really impossible on the Pix? Is it possible that the remote user can surf the internet through their local connection when it is connected to the VPN?

  Thank you very much for looking.

  PJ.

  Hello

  It is possible to connect via the client VPN Cisco to keep internet usage. You must use what is called the split tunneling. Below you will find a link how to set up the split tunneling:

• Disable the connection on PIX 7.0

  Nice day!

  How clear (reset) specified connection (defined by the source/destination/port port pair) on PIX 7.04 If nat-control is disabled and xlate not use?

  Thank you!

  You may use the shun command. This resets the connection but also will block future connections from the IP source address corresponding, ports and protocol specified in the shun...

  "Step 1 if necessary, to display connection information by entering the following command:

  See the hostname conn #.

  The security apparatus displays information about each connection, such as the following:

  TCP on 64.101.68.161:4300 in 10.86.194.60:23 idle 0:00:00 bytes 1297 flags UIO

  Step 2 to escape the logins from the source IP address, enter the following command:

  HostName (config) # shun src_ip [dst_ip src_port dest_port [Protocol]] [id_vlan vlan]

  If you enter only the IP address of the source, all future connections are rejected; existing connections

  stay active.

  To delete an existing connection, but also connections future blocking the source IP address, enter

  the destination IP address, source and destination ports, and Protocol. By default, the Protocol is 0 intellectual property.

  Step 3 to remove the shun, enter the following command:

  "HostName (config) # no shun src_ip [vlan id_vlan].

  I hope this helps... Please note if it is!

• How to force a clear connection on PIX 7.0

  Hi all

  In an earlier version of IOS PIX, yu could use clear xlate in cases where you have wanted to force a session to close.

  Now with PIX 7.0, nat is no longer necessary. But what is the alternative to clear the active connections (all or specific) indicated by the command 'sh conn detail "?

  Kind regards.

  'clear the local host' will delete all connections and xlates to an existing host, see http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_sw/v_70/70cmdref/c.htm#wp1378915 for more details.

• Connections by PIX 515 Citrix

  I have a site that is complaining that their Citrix connection is to have abandoned several times per day. This seems to be specific to the site. I read of some limited on some firewall at a specified time SSL connections.

  The PIX will limit connections to a specified time (active or inactive)? If so, how would it change? It is editable by IP address?

  The PIX will limit connections based on a timeout value. Time-out values are global and cannot be applied to an individual IP address. Time-out values can be changed with the command "timeout" in the PIX. You can view the current timeout values by issuing the command 'show timeout '. Here is a link for more information on the timeout command.

• 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.

• Half of the connections open on PIX

  How is possible to limit the number of half open connections on PIX? Are these embryonic connections on static instruction?

  M

  Hello

  That is right. By default, the emb_limit is set to zero, which allows unlimited half-open connections. It has a relatively low value and which should limit these types of connections...

• DMZ and PIX failover

  Hello

  I'm pretty happy with the tipping of inside and outside interfaces - i.e. the backup PIX inherits the IP address and MAC address of the main unit. However, what about the DMZ interface? Which also inherits the IP address and MAC of the primary unit?

  In a design of failover DMZ with only a couple of servers on the DMZ, you connect two PIX DMZ interfaces into a common switch (same VLAN of course!) and then plug servers?

  Pretty basic questions, I don't know, but I cannot find an answer to this on cco.

  Best regards, Steve

  Hi Steve,.

  Yes... DMZ interfaces inherited also the IP and MAC address of the primary PIX.

  In this scenario, even if you have a server you need to plug the 2 PIX on a switch and then the server on the same VLAN... This will ensure the physical accessibility of the server at the same time PIX. In case you have only a single connection, you must change the cable manually, when a PIX fails, which is a big headache...

  I hope this helps...

• Backup AAA for PIX

  I have a PIX with the following configuration:

  GANYMEDE + Protocol Ganymede + AAA-server

  AAA-server GANYMEDE + (inside) host 192.168.1.1 77777 timeout 5

  RADIUS Protocol RADIUS AAA server

  AAA-RADIUS (inside) host 192.168.1.1 Server 77777 timeout 10

  AAA-server local LOCAL Protocol

  AAA authentication GANYMEDE serial console +.

  AAA authentication enable console GANYMEDE +.

  order of AAA for authorization GANYMEDE +.

  AAA accounting correspond to aaa_acl inside RADIUS

  Everything works fine when the RADIUS server is available. When he is not available, I can log in with the username "PIX" and "password". The problem is, once I connected, I can't get permission to execute orders. Does anyone know of a command that is similar to the "if-certified" for routers that I can use?

  There is no method of backup for authorization for the PIX. As you know, if the RADIUS server is down, you can connect with "pix" and the password enable, but it doesn't help a permission. The only thing you can do is wait the GANYMEDE server back to the top. I'm sorry.

• PIX 515E failover

  I have a pair of PIX 515E (6.3) running in failover mode. They are currently connected to a single chassis base. We are upgrading our network with the heart, dual 6500's. Is there a way to connect each PIX to a separate kernel (1 PIX - Core1, PIX 2 - Core2) to allow a failure of the base?

  Core 1 and Core 2 will have a L2 link between them. If the current active PIX is connected to Core1 and Core 1 dies, this would not lead to support PIX failover. All LAN traffic would go through Core 2, but since he does not have an active path to the active PIX 1, traffic would drop. My reasoning is correct?

  Is there a way to connect the PIX to two cores running V6.3?

  Hello

  If you use the cable-based failover, you can change the basis of LAN failover.

  Read http://www.cisco.com/en/US/docs/security/pix/pix63/configuration/guide/failover.html#wp1024836

• PAT on IPSEC VPN (Pix 501)

  Hello

  I work to connect a PIX 501 VPN for a 3rd party hub 3015. The hub requires all traffic to come from a single source IP address. This IP address is assigned to me as z.z.z.z. I have successfully built the VPN and tested by mapping staticly internal IP with the IP address assigned, but cannot get the orders right to do with PAT in order to have more than one computer on the subnet 10.x.x.0. This Pix is also a backup for internet routing and NAT work currently as well for this.

  I can redirect traffic to my subnet to the remote subnet via the VPN, but I can't seem to get the right stuff PAT to the VPN using the assigned IP address. If anyone can give me some advice that would be great.

  Thank you!

  Dave

  Dave,

  (1) get rid of static electricity. Use more Global/NAT. The static method will create a permanent

  translation for your guests inside and they will always be this way natted. Use

  NAT of politics, on the contrary, as shown here:

  not static (inside, outside) z.z.z.z 10.x.x.50 netmask 255.255.255.255 0 0

  Global (outside) 2 z.z.z.z netmask 255.255.255.255

  (Inside) NAT 2-list of access 101

  (2) the statement, "nat (inside) access 0 2' list will prevent nat of your valuable traffic."

  Delete this because you need to nat 2 nat/global card. (as a general rule, simply you

  If you terminate VPN clients on your device and do not want inside the traffic which

  is intended for the vpn clients to be natted on the external interface).

  (3) with the instructions of Global/nat 2, all traffic destined for the remote network will be first

  translated into z.z.z.z. Then your card crypto using the ACL 103 will encrypt all traffic which

  sources of z.z.z.z for y.y.y.0 24. This translation wil happen only when traffic is destined for the vpn.

  I hope this helps. I have this work on many tunnels as you describe.

• PIX 501 with Actiontec Q1000 in Bridge mode

  I have an Actiontec Q1000 Qwest racetrack with 8 static IP addresses.  I want to put the Actiontec in bridge mode and connect the PIX.  I have configured the PIX as follows, but there are some things that are unclear to me:

  IP address outside pppoe setroute

  VPDN group chi request dialout pppoe

  VPDN group chi localname xxxxx

  VPDN group chi ppp authentication pap

  VPDN username password xxxxx xxxxx

  Qwest gave me a block of 8 IP, and they either of them specified as a gateway address.

  This IP will get the external interface?

  Can I use setroute with Qwest, or I need to specify a default route instead?

  Can I assign the gateway address to the external interface of the PIX?

  My ultimate goal is to be able to configure the PIX to allow client software Cisco VPN incoming connections.

  Thank you very much for all your comments.

  P.S. I can't just try, because I am in California and I need to set it up and send it to Utah, where I there will have access via SSH.

  The ip address will be given by provide it during the negotiation of PPPoE.

  You should be able to use the road together, I would expect Qwest provide the default route in PPPoE.

  I should get it by the ISP automatically.

  Please evaluate the useful messages.

• Static NAT on PIX 501 help

  I PIXA (192.168.27.0) PIXB (192.168.1.0) with a VPN connection.  I want to PIXB network 10.10.1.0 NAT when it connects to PIXA, so that when I do a ' sh ipsec his ' on PIXA, it shows the remote ident as 10.10.1.0 instead of 192.168.1.0.  I enclose my config PIXB.  Does anyone mind overlooking it and tell me what I'm doing wrong?  Thanks for all the ideas.

  1. remove the "nat (inside) 0 access-list NO - NAT"

  2. change acl 90 "access-list 90 allow ip 10.20.1.0 255.255.255.0 192.168.27.0 255.255.255.0.

  3. edit the ACL on the other end as well.
