• processing order of encryption and ACLs

  Hi people,

  I am preparing to a test lab and have the following scenario:

  R6---172.16.50/24---PIX---172.16.10/24--R1

  R6 I have two interfaces:

  lo0 6.6.6.6/24

  FA0/1 172.16.50.50/24

  R1 two int:

  lo0 1.1.1.1/24

  E0 172.16.10.1/24

  I want to protect all traffic between the 6.6.6.0 and network 1.1.1.0 with IPSec. I use ESP to protect traffic.

  Another condition is that I want to put an ACL to e0 allowing IPSec traffic.

  I created an ACL named ACL_E0_IN that is applied on e0 for inbound traffic.

  R1 #sh of access lists

  Expand the IP ACL_E0_IN access list

  esp permits 172.16.50.50 host 172.16.10.1 (15 matches)

  permit udp host 172.16.50.50 host 172.16.10.1 eq isakmp (116 matches)

  refuse the log host 1.1.1.1 icmp host 6.6.6.6 (5 matches)

  Ping of R6 R1 does not work:

  R6 #p 1.1.1.1 source lo 0

  Type to abort escape sequence.

  Send 5, echoes ICMP 100 bytes of 1.1.1.1, time-out is 2 seconds:

  Packet sent with the address source 6.6.6.6

  .....

  Success rate is 0% (0/5)

  R6 #.

  On the R1, I get the following message:

  * 8 Mar 03:58:37.917: % s-6-IPACCESSLOGDP: ACL_E0_IN denied icmp 6.6.6.6 - list

  > 1.1.1.1 (8/0), 4 packs

  This scenario works ONLY when I allow ICMP of R6 and ESP traffic.

  I wonder why the decrypted packets are denied by the ACL. I expect that the ACL is processed BEFORE the packet is decrypted. When I look at the meter on the hit of the ACL, it seems that the ACL is checked twice.

  Someone at - it an idea on the exact order of encryption and the treatment of the ACL?

  Thank you

  Michael

  Attached you will find the configs of the R1 and R6

  Michael

  I recently saw an explanation of encryption and ACLs that indicates there has recently been a change in behavior. In most versions of IOS, the behavior is as you describe, the package is evaluated by the ACL twice. The explanation is that the package is evaluated first in his State encrypted to check that it was something that must be dealt with. After the package has been decrypted, the IOS necessary to assess the package decrypted to see if things like the quality of Service necessary to apply. So basically the decrypted packet passed through the interface again and the ACL again. In recent versions of the code (12.3 (4) T, if memory serves) a change has been made and the package will now go through the ACL only once.

• Satellite 5100 501 and installation of Vista

  Hello!

  Is it possible to run Vista Business on 5100-501? No problem with drivers?

• ASA 5520 IPSEC L2L and ACL

  Just a quick question.  I have two ASA with a vpn site-to-site tunnel built between them.  One is the Central Administration

  site and the other is a remote site.   On the remote site, I have the following IP as local hosts:

  192.168.1.5

  192.168.1.6

  192.168.1.55

  Those workstations attempt to access networks according to destination

  10.1.1.0 24

  10.1.2.0 24

  10.1.3.0 24

  In my interesting traffic on the remote end, I set myself to use

  IP 192.168.1.0 255.255.255.0---> 10.1.0.0 255.255.0.0

  On the side of the Central Headquarters, my interesting traffic looks like

  IP 10.1.0.0 255.255.0.0---> 192.168.1.0 255.255.255.0

  So now I'm encrypting IP traffic between 10.1.0.0 24 16 to 192.168.1.0.   This part works very well.    But now I want to put an ACL

  the tunnel to allow ONLY 3 hosts on the 192.168.1.x on some ports for 3 subnets.   This is done by group policy for a tunnel from Lan Lan 2.  If I apply a group policy and define a filter of IPV4.  This will accomplish what I'm shooting?

  I am doing this on the ASDM, so keep this in mind when you try to explain to me how to solve this problem.

  Thanks in advance,

  I should stay in bed...

• 1.2 of the ISE and ACL with several ports

  When you create a DACL for my groups I used the syntax "permit tcp any 192.168.20.0 0.0.0.255 eq 22 443" for one of my acl within the DACL and the validated syntax checking. When I pushed my groups too, it worked but I have heard that this type of port several ACL in ISE is not supported. Does anyone know if this is accurate?

  You can implement several DACL to control access and the sound works perfectly with ISE

• PIX IPSec and ACL issues

  Hello

  On a PIX 515E v.6.3.5.

  There are three lists ACL that can come into play when setting up an IPSec VPN on a PIX? (I hear a sound of 'It depends')

  1 Nat (0) ACL - NOT NAT traffic, it is part of the IPSec VPN

  2 crypto ACL - ACL that distinguishes if the traffic is destined for the IPSec tunnel.

  3 ACL - ACL to allow | deny traffic after ACL #1 and #2.

  #3 "Allow packet IPSec to bypass the blocking of access list" If the "ipsec sysopt connection permit" command is configured and ONLY for the #3 ACL? In other words the sysopt does not participate on ACL #1 or 2 above?

  The mirroring of the ACL, which is suggested (required) to both sides of the tunnel IPSec applies to what ACL?

  Thank you

  It depends on

  (1) is not always used, because with a site to site VPN sometimes you need to NAT your addressing internal

  (2) always necessary

  (3) if the "ipsec sysopt connection permit" is set up any ACLs on the interface where the VPN is finished is bypassed. If it is not enabled then once packets are decrypted they are then checked against the acl.

  Mirrored ACLs is required.

• L2L pix 501 and remote access VPN

  Hi, I'm working on an old 501 PIX w / Software 6.3 (5), he already have access to remote VPN configuration and works very well, but now he needs a L2L implemented. One thing I try to do all the work remotely via VPN or ssh to the machine. I don't know what's on the other end, but they swear that it is set up and maybe my problem is when I start putting in orders for the other VPN it breaks the remote VPN access. One thing that I have to do is NAT a host on the inside to appear as another host on the end. I use these commands and I think it works cannot be said.

  access-list 101 permit ip remote_network 255.255.255.0 local_server host

  public static 10.1.0.203 (inside, outside) - access list 101

  then

  access-list 102 permit ip host 10.1.0.203 192.168.50.83
  access-list 102 permit ip host 10.1.0.203 192.168.50.86
  access-list 102 permit ip host 10.1.0.203 192.168.50.50
  access-list 102 permit ip host 10.1.0.203 192.168.50.85

  and use it to match against

  Crypto ipsec transform-set esp-SHA-ESP-3DES-3des esp-sha-hmac
  EMDs-map 10 ipsec-isakmp crypto map
  correspondence address card crypto emds-map 10 102
  card crypto emds-map 10 peers set remote_vpn_server
  card crypto emds-card 10 set of transformation-ESP-3DES-SHA

  then

  ISAKMP key magic_key address remote_vpn_server netmask 255.255.255.255
  ISAKMP identity hostname
  part of pre authentication ISAKMP policy 10
  ISAKMP policy 10 3des encryption
  ISAKMP policy 10 sha hash
  10 1 ISAKMP policy group
  ISAKMP life duration strategy 10 86400

  and that is where it usually breaks the VPN, I don't know if the other VPN works due to not being not able to get to this server to try to ping, I don't really like to try this stuff remotely but I don't have a lot of choice at the moment.

  Any thoughts?

  Thank you

  Jarrid Graham

  Yes, just use the number of different sequence with 1 name of the crypto map. Please also ensure that your dynamic crypto map, which is your vpn client has the sequence down the crypto map (more), because you want to make sure that the static crypto map (for lan-to-lan tunnel has higher sequence number (lower number)).

  The political isakmp sequence number does not match, it is processed from top to bottom (number less than the high number) and also long 1 set of isakmp policy corresponds to the remote peer, it will be negotiated properly.

  Hope that answers your question and please note useful post. Thank you.

• Problems with PIX 501 and Server MS Cert

  Hi all

  I have two problems with my PIX 501:

  1. registration works well. The pix has a certificate and use it with SSL and VPN connections. But after a refill, the pix certificate is lost and it has regenerated again self-signed certificate!

  Yes, I wrote mem and ca records all!

  2. at the request of ca CRL , I get the following debugging:

  Crypto CA thread wakes!

  CRYPTO_PKI: Cannot be named County ava

  CRYPTO_PKI: transaction GetCRL completed

  Crypto CA thread sleeps!

  CI thread wakes!

  And the CRL is empty.

  Does anyone have any idea?

  Bert Koelewijn

  Not sure about 1, but 2 is usually caused by the COP (Point of Distribution of CRL, basically the situation where the PIX can download the Revocation list from) listed in cert CA is in a format the PIX does not, generally an LDAP URL.

  Check the following prayer:

  Open the administration tool of CA (Certification Authority) then

  (1) right click on the name of CA and choose 'properties '.

  2) click on the tab "Policy Module".

  3) click on the button "configure."

  4) click on the tab "X.509 extensions".

  > From there, it can display the list of the "CRL Distribution Points".

  Turn off everything that isn't HTTP.

  You need to reinstall the CERT in the PIX, I think, but then it should be able to download the CRL through HTTP instead of LDAP.

  your external ACL must mention the public IP address of your server:

• PIX 501 and THE, 3DES, AES

  For a version newly produced PIX 501,

  (1) are DES, 3DES and AES activation keys all pre-installed?

  (2) how I can find on which of them is pre-installed on my PIX 501?

  (3) when I create a server VPN (on the PIX 501), I see that all three OF THEM, 3DES and AES are available in the drop-down list of the PDM configuration screen. Does that mean my PIX 501 have all three of them (FROM THE, 3DES and AES)? -If the answer is no, assume that only is preinstalled on PIX 501, then why/how can appear in the drop-down list the 3DES and AES?

• Update from 11.2.0.4 to 12.1.0.2 and ACL

  Hello;

  Oracle Linux 6.7

  Oracle 11.2.0.4

  During the manual upgrade of Oracle 11.2.0.4 Oracle 12.1.0.2, I stumbled on ORA-01830 which was corrected by dropping the ACL, I had created.

  I looked at MOS 1958876.1 and the query, it provides "extract/backup xml stored ACL.

  My simple question is someone have a better query for that they are willing to share?

  Best regards

  mseberg

  Lesson

  Do not use "extract/backup xml stored ACL. Drop the ACL and recreate

  So if the ACL has been abandoned, I will need the following to recreate:

  ACL - DBA_NETWORK_ACL_PRIVILEGES

  Description

  main - DBA_NETWORK_ACL_PRIVILEGES

  IS_GRANT - DBA_NETWORK_ACL_PRIVILEGES

  privilege - DBA_NETWORK_ACL_PRIVILEGES

  Home - DBA_NETWORK_ACLS

  lower_port - DBA_NETWORK_ACLS

  upper_port - DBA_NETWORK_ACLS

  Description may not correspond to the former, but that's all.

  Hi "Hunk09"

  Sorry for apparently asking obvious questions, but I can not assume anything.

  (1) is your SMTP Server / SMTP relay really on your database server where the APEX is installed?

  (2) it listens on port 25?

  (3) you seem to have APEX 4.1 installed previously. Have you had this same problem with APEX 4.1?

  (4) your e-mail settings for instance in APEX Instance Administration level also specify localhost on port 25?

• After hard frustrations drive and the computer.

  Well, I'll start by saying that I searched google for answers and I'm getting a bunch of mixed responses and comments. So im here in the hope of figuring this out.

  I have a Dell Inspiron 531 and it came with Vista (chills just ran down my back! haha). Well recently I went to the front and did install a clean windows 10 on it. It seems that his works really well with it too... except for a number of things.

  I tried to install a 2nd hard drive but it does not recognize the hard drive in the Disk Manager, and he will not find it in BIOS boot. The hard drive is not an SSD, it's a 1 to that was in my old computer (which was running windows 7 on it). I don't want windows 7 or something like that on it as an OS to boot from the 2nd. All storage. But it does not detect on my computer.

  So here's some info that might help you...

  I checked the cables to the hard drive, but also put the SATA cable into different SATA ports on the motherboard and using different SATA data cables. The hard drive in my other old computer still works. So it seems the HD is not the problem.

  I noticed the BIOS is 1.0.7 and currently available is 1.0.13 and I have to use one day of BACK or something like that. But some places online say that I shouldn't update the BIOS because I can damage the computer. Some say that I have windows XP?

  The computer is still a clean install and it looks like windows 10 installed all the drivers for everything.

  Should I update the BIOS? Do you think the windows 7 OS on 2nd hard drive it keeps popping up?

  IM also decided to do a clean reinstall of windows 10 but this time, following the order of update on the dell site ("install the drivers in the order of: applications, drivers, firmware and BIOS"). I would like to know what you think of this idea... or maybe to install BIOS first then the rest.

  I also installed an AMD Radeon R5 220 in the computer. It takes a little more time to start. Is this normal? I wanted to have two screens, so I just skipped that in and it seems to work fine except for the departure to the top. It takes more time to start before the dell logo appears. Then it's a quick start from that.

  Sorry for the late reply. I dealt with the work.

  I understand later.

  In the BIOS if you will to...   Advanced > Integrated Peripherals > Configuration Serial - ATA, then assign the controller SATA SATA 1 + 2

  And that's all!
