PIX and Anti-Spoofing

Similar Questions

• Question realted anti-spoofing feature on PIX

  (1) is there an anti-spoofing feature on PIX firewall?

  (2) if it is respected, how are they implemented? It is being implemented by default? And how do you control the anti-spoofing rules?

  (3) if it is respected, is they are implemented at layer 1 or 2, or only at the level of the layer 3 (IE RPF of the CBAC and access-list)?

  Hi, I would like to give one of these:

  (1) the only spoofing that PIX offer short configuration to block addresses RFC 1812, inside addresses, access networks bogon lists, etc. is to configure path reverse unicast. Have a look here:

  http://www.Cisco.com/univercd/CC/TD/doc/product/iaabu/PIX/pix_sw/v_63/cmdref/GL.htm#1053009

  (2) RPF is not implemented by default. You must configure this if wanted.

  (3) layer 3 only.

  I hope this helps.

• PIX and ASA static, dynamic and RA VPN does not

  Hello

  I am facing a very interesting problem between a PIX 515 and an ASA 5510.

  The PIX is in HQ and has several dynamic VPN connections (around 130) and IPsec vpn remote works very well. I had to add a PIX to ASA L2L VPN static and it does not work as it is supposed to be. The ASA 5510, at the remote end, connects and rest for a small period of time, however, all other VPN connections stop working.

  The most interesting thing is that ASA is associated with the dynamic map and not the static map that I created (check by sh crypto ipsec his counterpart x.x.x.x). However, if I make any changes in the ACL 'ACL-Remote' it affects the tunnel between the PIX and ASA.

  Someone saw something like that?

  Here is more detailed information:

  HQ - IOS 8.0 (3) - PIX 515

  ASA 5510 - IOS 7.2 (3) - remote provider

  Several Huawei and Cisco routers dynamically connected via ADSL

  Several users remote access IPsec

  A VPN site-to site static between PIX and ASA - does not.

  Here is the config on the PIX:

  Crypto ipsec transform-set ESP-3DES-ESP-SHA-HMAC-IPSec esp-3des esp-sha-hmac

  Dyn - VPN game 100 Dynamics-card crypto transform-set ESP-3DES-ESP-SHA-HMAC-IPSec

  Crypto dynamic-map Dyn - VPN 100 the value reverse-road

  The problem is that the ASA has a crypto acl defined between host and network, while the remote end has to the network.

  Make sure that the acl is reversed.

• PIX and NAT - T

  Hi all

  I have a small question. I have a couple of users who use routers to connect by VPN to our pix that authenticates by a RAY for L2TP connections. I enabled the NAT - T on our PIX and they may not always connect. Is there anything I might have missed. I checked most of the posts in this forum do not see anything else, I should have activated.

  Can anyone help?

  Thanks in advance.

  A tunnel of Lan-to-Lan of a router in a PIX does not NAT - T, unless there is NAT devices between two end points. If this is the case, you must ensure that both the software both from the end of rehbeh points devices support this capability. An example of a router to tunnel PIX IPSec configuration is available at http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080094498.shtml

• VPN between a PIX and a VPN 3000

  I'm trying to set up a VPN between PIX and a VPN 3000. All configurations are complete, but the tunnel has not been established. On the PIX, to 'see the crypto engine' and ' show isakmp his ' orders, I do not see the tunnel. Of "show ipsec his ' command, I can see the mistakes"#send"continues to increase when I try to connect to the remote network. Here is the copy - paste command:

  Obviously, the PIX identifies protected traffic but failed to establish the tunnel. I was wondering what could be the reason for these kind of mistakes? That means them growing '#send errors?

  Thank you very much!

  Sending error mean simply the PIX is grateful to encrypt this traffic, but there is no built tunnel and so it must drop the package.

  you will need to look at why the tunnel is not under construction however, "sending error" are just a byproduct of some other configuration issue. On the PIX, it looks like you would have something like:

  Crypto ip 10.70.24.128 access list allow 255.255.255.128 10.96.0.0 255.224.0.0

  On the 3000 under the L2L section and the Local and remote network, you need the exact opposite of the latter, then it would be:

  / Local network mask = 10.96.0.0/0.31.255.255

  / Remote network mask = 10.70.24.128/0.0.0.127

  If you have something else the tunnel will fail to come. Otherwise, we see that the Cryptography debugs the PIX and the trunk of the 3000 when the tunnel is built.

• PIX and non - IP traffic

  I need to install a PIX 501 in a network. The internal interface is connected to my local network and that the external interface is connected to e0 interface of the router.

  The LAN have LLC,(2) and IP traffic. Is possible to LLC,(2) traffic through the firewall without tunnel? Can I connected another interface on the router in the local network only to traffic ll2?

  Thank you

  The PIX only manages the IP traffic, so unless tyou can encapsulate your traffic IP LLC, the PIX won't touch it. I guess you can bypass the PIX and connect a LLC,(2) interface that is only on the router in your home network, depends on how secure you want to be. Make sure that you do not configure an IP address on the router interface, otherwise you will run the risk of someone circumvent security of PIX.

• Version 7.0 of the PIX and ASA 5500

  Hi all

  Is ASA 5500 series identical a PIX 515 or 525 or 535 with version 7.0... I still see some areas where it confused between version 7.0 of the PIX and ASA 5500 series... If not, what are the benefits of ASA 5500 on the PIX 7.0?

  ASA is not the same as PIX, ASA is different hardware architecture. Although both can run the same code. One of the benefits of the SAA is that you can have an IPS module in it to make the prevention of intrusions.

  Search for comprarison on CCO.

  I looked on the internet and that it points to a routing error when packets are being encrypted and decrypted, but you can't do a ping on the binding. However when I test the connection I did not enter any of the static routes that networks are connected directly on each side of the pix and the router. any help would be a preciated as I think there's maybe something is blocking the ping to reach the internal network at the end of pix with a configured access list.

  is ping failure of the only thing between the site to site VPN? and assuming that all other traffic works fine since it decrypts and encrypts the packets.

  If it's just ping, then activate pls what follows on the PIX:

  If it is version 6.3 and below: fixup protocol icmp

  If it is version 7.0 and higher: select "inspect icmp" under your political map of the world.

  Config complete hand and on the other could help determine if it's a configuration problem or another problem.

• Stop Internet connection malware and Anti-Malware software

  Hello! I have a 2015 MacBook Pro that I use to the work of the College, as you can imagine, I have a lot of important information about this. That being said, I probably should be more careful by browsing the internet, but I have unfortunately seem to have fallen for a 'Java update' Malware thing and have successfully infected my laptop by malicious software.

  After reading a few recommendations online, I downloaded MalwareBytes Anti-Malware free and he ran. It is is immediately detected the dangerous Malware and gave me the ability to clean my computer from harmful programs. After he cleaned my computer, it restarted and opened upward.

  Not only does the Malware not go far, but it got worse: as soon as the screen is turned on, a bunch of windows appeared, with statements such as: "accountsd wants to use the"login"keychain." & "com.apple.iCloud.Helper.xpc wants to use the"login"keychain". These windows do not disappear when you press Cancel, and I'm afraid to put a password in while my laptop is still affected by the Malware.

  Second, none of my browsers will connect to internet. Google Chrome is no longer loads all pages and now often needs to be force-leave out. Finally, MalwareBytes Anti-Malware won't open and it immediately passes "Application not responding" when opening.

  Can someone please help me with a solution to this problem? It would be greatly appreciated.

  If you have voluntarily or involuntarily exposed your computer to potentially dangerous software, you should consider a backup of your system and a reinstallation of the operating system as no single or multiple scan of your computer can completely provide an accurate assessment of what has been allowed to infiltrate your computer.
