• peer cvpn through pix and ending the pix

  Can someone point me to a document or explanation on why ipsec must be open on the first pix to IPSEC to cross because he hails from this network? I can't find a document that explains better that I can or includes the above scenario for the layman.

  The PIX opens only the holes for the return for TCP and UDP based traffic. IPSec ESP is located just above IP and is therefore not based TCP/UDP. For this reason, you must specifically allow Protocol IP 50 (ESP) in the PIX from the outside, because as I said, the PIX will not open a hole to get him back.

  He done the same for the ICMP protocol, it takes of icmp in the PIX, if you want your interior to the users to be able to ping outside guests. Because ICMP is not based of TCP/UDP, the PIX does not open a hole for the return to return to traffic.

  Now, that said everything that, in point 6.3, they added a '' correction '' ESP, so the PIX could inspect the outbound ESP for A a SINGLE TUNNEL, he PAT to the address of the external interface and allow the return of traffic to. It is disabled by default, you can activate it with the following text:

  fixup protocol esp-ike

• Allowing the CPP through a PIX can afford some program only numbers?

  I can allow inbound access to port 111 allowing embryonic incoming connections for the purposes of the CPP. There is a big hole in security.

  Cbac on a router, you can inspect and allow some RPC program numbers. Is it possible to do it in the PIX firewall?

  Thank you very much

  Mark

  Mark,

  No, the PIX has no capability (such as CBAC) to inspect RPC program numbers. We offer limited fixup UDP RPC portmapper and rpcbind exchanges. I hope this helps.

• Fleeing from a host on the PIX 520 but alerts that are still coming to the IDS

  Last week I saw allot of traffic from a particular host that triggers alerts IDS. After investigating the source, I added a statement SHUN to the pix. When I do a 'sho shun stat' of the NTC for this host is quite high (352) and rises. I still get alerts of the IDS on this particular host (Fragment IP and host sweeps). I guess if I was fleeing from an IP address, I don't receive alerts of IDS on that. Can someone explain what I am doing wrong? Thanks in advance.

  Seems obvious, but can't hurt to ask - where the sniff of your sensor interface? Of course, if your sniffing interface is located outside the pix, then junk traffic will always reach the pix - it just won't be through it.

  In addition, are fleeing this host for these alarms? Doing a show 'show shun' that host being blocked FOR the time you see alerts for this particular host?

• Telnet to the PIX from the outside

  I tried the task through several suggestions.

  None of which worked. My last try was using this link.

  http://www.Cisco.com/en/us/customer/products/sw/secursw/ps2120/products_user_guide_chapter09186a0080089bd6.html

  PIX VPN client works fine however I am still unable to telnet to the PIX.

  In addition, the document speaks of configuration on the client.

  Step 3 in the VPN client, create a security policy that specifies the IP address of the remote party identity and IP gateway under the same IP address IP address of the external interface of the PIX firewall. In this example, the IP address of the PIX firewall outside is 168.20.1.5.

  I see there is only one place to put an IP address on the client. There is no place on the client to a gateway address. I tried to change my gateway machine and it still does not work.

  Does anyone have a config to work on how to Telnet to a PIX from the outside?

  The step that you are referencing is for users who use the old client VPN CiscoSecure. Do you really use that? I'm guessing that you are actually using the VPN client 3000, in which case you just have:

  (1) an acl of encryption that allows the traffic of your address has been assigned outside the pix

  (2) a statement of telnet that allows telnet address assigned from outside

  i.e.

  no_nat of ip host 200.1.1.1 access list permit 10.1.1.100

  Telnet 10.1.1.100 255.255.255.255 outside

• Multiple connections to the PIX VPN

  Is it possible to put an end to a simple VPN for the PIX to provide remote access, but at the same time set up an another tunel VPN between the PIX and another firewall to provide access from the internal network to the external?

  Thanks in advance!

  Yes, you can have client and L2L tunnels configured on the pix together. If you talk to redirect traffic so that the customer can speak through the L2L at the remote network as well, here's a link: http://www.cisco.com/warp/public/110/client-pixhub.html

  Here is a link to just the client for the pix configuration:

• How to limit the ICMP on the PIX firewall.

  Guys good day!

  I have a dilemma with regard to limiting ICMP users browsing to other networks such as other demilitarized interns.

  I know that, to allow ICMP to pass through interfaces, you will need to create an ACL such as below:

  access-list DMZACL allow icmp a whole

  Users require this config ping a server on the DMZ, but it is a security risk.

  To minimize, I have a group of objects created in order to identify hosts and networks is allowed to have access to the echo-replies.

  Again, this is a problem since many host who extended pings just to monitor the connectivity server and its application.

  Do you have other ideas guys?

  As to limiting the echo answers on the PIX. As first 5 echo request succeed with 5 echo-replies and the rest would be removed.

  This could be done?

  Thank you

  Chris

  Hello.. I don't think you can do this by using an ACL on the PIX, however, you might be able to stop the ICMP sweeps by activating CODES signatures using the check ip command you... For more information see the link below

  Guidelines of use Cisco Intrusion Detection System (IDS Cisco) provides the following for IP-based systems:

  ? Audit of traffic. The application of signatures will be audited only as part of an active session.

  ? Apply to the verification of an interface.

  ? Supports different auditing policies. Traffic that matches a signature triggers a range of configurable

  actions.

  ? Disables signature verification.

  ? Always turns the shares of a class of signature and allows IDS (information, attack).

  The audit is performed by looking at IP packets to their arrival at an input interface, if a packet triggers

  a signature and the action configured does not have the package, and then the same package may trigger another

  signatures.

  Firewall PIX supports inbound and outbound audit.

  For a complete list signatures of Cisco IDS supported, their wording and whether they are attacking or

  informational messages, see Messages in Log System Cisco PIX Firewall.

  See the User Guide for the Cisco Secure Intrusion Detection System Version 2.2.1 for more information

• Conentrator PIX using NAT on the PIX?

  Hello

  I'm looking for the docs on how to set up an ipsec tunnel hub pix, all the IP behind the pix (inside) should be NAT'ed to a single IP address and have access to the network behind the hub.

  Any help will be appreciated.

  TYIA

  Yes, makes no difference. The policy-NAT'ing for IPsec traffic has priority over the standard PAT for Internet traffic, so traffic above the tunnel will be policy-NAT would rather than 'normal' NAT would be on his way through. ACL encryption will match while the packet is sent, and it will be encrypted and sent via the tunnel.

• To connect outbound PPTP through a PIX

  I have problems getting one of my PIX firewall to allow a connection PPTP to a machine inside the network to a server on the outside. I found and tried some things listed in the document, following the examples of PIX.

  http://www.Cisco.com/warp/public/110/pix_pptp.PDF

  My situation is slightly different in that, although I'm under code of 6.3, but we still use statements led. Can someone tell me what is needed to make this work? I do PAT on the PIX. In addition, there is a statement static for the machine inside which tries to establish a PPTP connection if that help/made a difference.

  Any comments on this would be greatly appreciated.

  Justin Loucks

  Hi Justin,

  Make sure that you open ports tcp 1723 of inside outdoors... you have everything inside the access list? lines anyway don't matter, because the traffic is from the inside to the outside... fixup protocol pptp 1723 is a very large order... He used normally work without this...

  also make sure that if the other end (where the server is hosted), allows traffic from outside inside (conduit or ACL)... Make sure that you open tcp 1723 at the other end...

• Configuration of the PIX 520 with two links to Internet

  Hello.

  I have a pix 520 with four interfaces ethernet firewall, in fact I am with

  just two interfaces,

  Ethernet 0 outdoors

  Ethernet 1 inside

  ethernet2 closed intf2

  ethernet3 closed intf3

  Thus, in the interface to the outside, I have access to the internet, but now I

  access to the internet and I want to configure the two, I mean,.

  a single network inside and two internet access,

  is it posible?

  the perhaps configuration.

  Ethernet 0 (access 1) outdoors

  1 Ethernet (ip 10.1.1.1) inside

  ethernet2 outside2 (access to internet 2)

  ethernet3 inside2? (ip 10.1.1.2)?

  Thanks for the help,

  You can plug it in like that, but there is no way to route traffic by default. PIX does not support this type of connections that you can only configure a default route on the pix. This link should help describe what you can do: http://www.cisco.com/warp/public/110/pixfaq.shtml#Q18

  I hope this helps.

• Comment by instructions in the PIX config file?

  Hello

  Is there a way of declarations of entry comment in a PIX config file? If so, how?

  TIA

  Prefix the line with a: (colon).

  for example. The first line of the following is a comment and is ignored

  : Allow access to the Web server

  acl_outside list access permit tcp any host 1.1.1.1 eq www

  Note: Comment lines are deleted when the configuration file is entered in the PIX.

• Configure the PIX 501 for IDS

  I have a PIX 501 with wired high-speed LAN headquarters inside and outside. Which would be a solid policy IDS to enable and what interfaces it must be applied to? There will be other measures necessary to enable IDS?

  IDS on the PIX itself is very limited, it checks only 59 signatures listed here (http://www.cisco.com/univercd/cc/td/doc/product/iaabu/pix/pix_62/cmdref/gl.htm#xtocid9 under the section of signatures supported IDS). The signatures themselves are pretty basic.

  If you do not want to activate this, then for the signatures of attacks I would fix for drop/alarm/reset action, which is the default anyway.

  You will also need to set the logging to a syslog server and monitoring for any 4000nn messages in syslog, cause it event IDS.

• DES/3DES license needed for the PIX 515 active/active configuration.

  Hello

  I am setting up two PIX active/active.

  My problem is that the PIX without restrictions, the 3DES activated license but the FO - AA that just the license OF.

  I would like to know if it is possible to downgrade the 3DES to just unlimited license OF (I know that the alternative would be to upgrade the FO - AA 3DES but I don't need this license).

  Thank you.

  Javier,

  You can get FREE 3DES/AES license of Cisco for your PIX, go here:

• Cisco 3640 to the PIX 501 site 2 site VPN performance specifications.

  I intend on creating a site-2-site VPN in Star configuration with a Cisco 3640 as the hub and PIX 501 at the remote sites. My question is around the plug that I read.

  .

  The specifications for a PIX-501-BUN-K9 tell PIX 501 3DES Bundle (chassis, SW, 10 users, 3DES).

  .

  A question is what really "10 users. Which is the limit of the number of concurrent sessions, I have on the VPN at a given time, or that it means something else?

  .

  I also read the specs say that the Maximum number of VPN tunnels that can support a PIX 501 is 5. Because I'm not going to make a tunnel between the PIX 501 at the remote site and the 3640 on the central site, I think I would be OK. Is that correct or is the max value talk the maximum number of concurrent sessions on the tunnel tunnels?

  .

  Thank you.

  UDP traffic always creates a session in the PIX so that the return traffic will be allowed in. The UDP timeout is 2 minutes but IIRC. If you go around NAT with a statement of "nat 0" should not create an xlate I think.

  The real time is hard to say really, probably around 2 minutes for a UDP-only user, you would probably make a few 'local sho' orders on the PIX to really see for sure however.
