• PIX with VPN to Checkpoint with overlapping subnets

  I have a client with a PIX runs code 6.3.

  They need establish an IPSec Tunnel for one of its customers with a Checkpoint firewall.

  Both organizations use 10.1.0.0/16 and I'd like to nat to 10.180.0.0 Home Office 16 and the remote client to 10.181.0.0.

  The document on the site Web of Cisco PIX and VPN concentrators is less useful. I don't think the text describing the image is correct.

  Help with ACL and static NAT is greatly appreciated.

  Frederik

  Apologies, should have asked. Which office has the pix and the control point. I write this as if the two ends were firewall pix so that's fine and we can see if that helps.

  Remote endpoint

  ==========

  NAT 10.1.0.0 ip access list allow 255.255.255.0 host 10.180.1.103

  NAT (inside) 3 access list NAT

  Global (outside) 10.181.0.0 255.255.0.0

  NOTE: You could really just NAT addresses 10.1.x.x from source to a global IP address rather than the whole 10.181.0.0/16 up to you.

  Your card crypto access list must then refer to the addressing of Natted 10.181.x.x rather than the 10.1.0.0 address.

  vpntraffic list access ip 10.181.0.0 255.255.0.0 allow host 10.180.1.103

  Main office

  ===========

  crpyto-access list should read

  vpntraffic list allowed access host 10.180.1.103 ip 10.181.0.0 255.255.0.0

  And you will need a static translation for client access

  public static 10.180.1.103 (Interior, exterior) 10.1.1.103 netmask 255.255.255.255

  Does that help?

• PIX 525 VPN

  What is the process to configure a firewall to Firewall VPN. What is the advantage of this?

  You are able to do this from a PIX firewall to another provider?

  PIX - Pix avoids having to run a VPN Client to access another network. The PIX uses IPSec, which is compatible standards, you can connect to 3rd party so material.

• Access list ID # on a PIX firewall

  Is anyone know what of the identifier access list on a pix firewall?

  Standard IOS = 1-99

  Extended IOS is 100-199.

  SW = PIX?

  There is no "limit" by Word to say in the Pix. These limits are in IOS because they define what 'type' of acl, it's IE APPLETALK, IPX, IP etc etc. Pix IP is therefore not necessary for this type of identification.

  access-list 100000000000000; 1 items

  allow line of the access list 1 100000000000000 ip any a (hitcnt = 0)

• Cisco ACS and Pix Firewall

  I have configured the aaa authentication in the pix firewall to see the ACS RADIUS Server for verification of the user. If the ACS server becomes unavailable, then I could not connet the pix firewall.

  In the router, I have the configuration option

  AAA authentication login default group Ganymede + local

  that tells the router first looking for a radius server and if is not available connect through the local database.

  Is there an option in the Cisco pix firewall to connect using local information if ACS is not available?

  Thanks in advance

  Hello

  PIX back up method to entered the unit in the event of server failure aaa works on 6.3.4 code and above. In the codes plus late 6.3.4 If the RADIUS server fails it is impossible to get in unless password recovery. "However if we have not configured for console aaa authentication than user name: pix and password: cisco" works by default.

  Kind regards

• PIX firewall problem

  I have two servers, one in pix inside and the other in the demilitarized zone. I wanted to set them up so that they can communicate with routers and switches

  Located outside the pix firewall.

  My inner Server works fine, able to go Internet and able to comminicate with all devices located outside the Pix Firewall. Here is reference configuration

  of insideserver.

  outside_acl list extended access allowed host x.223.188.0 255.255.255.0 172.28.32.50 ip

  outside_acl list extended access permit ip host host x.219.212.217 172.28.32.50

  access-list extended sheep permit ip host 172.28.32.50 host x.219.212.217

  access-list extended sheep permit ip host 172.28.32.50 x.223.188.0 255.255.255.0

  inside_acl list extended access permit ip host 172.28.32.50 all

  But my DMZ server does not work. However, I made the same configuration with respect to the server on the inside. Not able to communicate with outside DMZ server

  network.

  outside_acl list extended access allowed host x.223.188.0 255.255.255.0 172.28.92.72 ip

  outside_acl list extended access permit ip host host x.219.212.217 172.28.92.72

  access-list extended sheep permit ip host 172.28.92.72 host x.219.212.217

  access-list extended sheep permit ip host 172.28.92.72 x.223.188.0 255.255.255.0

  dmz_acl list extended access permit ip host 172.28.92.72 all

  If I create a static entry for your DMZ SNMP server.

  static (edn, external) 172.28.92.72 172.28.92.72 netmask 255.255.255.255

  He starts to communicate with external devices, but stops Internet run on this server. same configuration

  works with the server on the inside, but not with dmz server.

  NAT (inside) 0 access-list sheep

  NAT (inside) 3 172.28.32.0 255.255.255.0

  NAT (dmz) 3 172.28.92.0 255.255.255.0

  Global interface 3 (external)

  Your static entry is bypassing your nat (dmz) 3 entry. You can do NAT exemption instead, as you do to your home

  1. remove the static entry (followed by clear xlate)

  Add - nat 0 access-list sheep (dmz)

  I suggest to use two acl different sheep, one for each interface.

  Ex: nonat_inside

  nonat_dmz

• 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

  on each signature. You can view the? NSDB and Signatures? Chapter of this guide at the following

• Place a server behind a PIX firewall production

  Hi all

  We currently have a web server that is connected to the Internet directly (multiple addressable IPs belonging to 5 different ranges of class C, with a soft firewall).

  There are several Web sites, some of them with their own IP addresses, some of them sharing IPs with other sites.

  We intend to put a server behind a PIX firewall and convert addressable IP addresses to private IPs with the static mapping on the PIX.

  We plan use a PIX with two (2) interfaces.

  You think it of feasible or are there things that I'm on?

  Some things I'm not sure about:

  Since there are several C class IPs assigned to the server and therefore 5 gateways defined on a NIC, one for each class, how that is defined on the PIX? 5 separate roads or...?

  We need to use a kind of "virtual interfaces", one for each class C subnet?

  This is an example of a "final product":

  Web request to the 204.xxx.85.10 IP addressable would be directed to the private IP address: 10.xxx.85.10.

  Web request to the 204.xxx.86.10 IP addressable would go to 10.xxx.86.10 etc etc.

  Any help you could provide in this regard will be GREATLY apprechiated!

  Hello

  Please provide a topology (plain text would work). I can't tell from your description, if you have a perimeter router in front of the Pix. In addition, when you write statements of static road on the Pix, you must include an interface as follows

  Route if_name IPAddress netmask gateway_ip

  Once you post this information, I'll take another reading to better understand your situation.

  Thank you

• PIX firewall Security Guide

  Hi guys, I noticed that there is a document on the setting of the Cisco routers on cisco.com

  Is there than a best practices similar document type for Secure PIX firewall? or even a general firewall best practices guides?

  I searched, but did not really find anything. Any help would be great!

  Hi Nathan,

  So far, there is no specific doc, but you can get the idea of documentation PIX / ASA itself. This is probably due to the nature 'trust' of the firewall itself (everybody knows that it was not 100% sure).

  Anyway, there is a document on "Best practices of firewall" at http://www.principlelogic.com.

  Others are:

  http://www.Security.FSU.edu/firewall.cfm

  http://SearchSecurity.TechTarget.com/originalContent/0, 289142, sid14_gci838230, 00.html

  Personally, I think the recommendations are very good and can be applied generally to fix most of the firewall products.

  I hope this helps.
