• VPN inside a PIX (General Questions)

  Hello

  I'm trying to implement a scenario of communication between a customer inside a pix that talks to a server on the outside. The customer must have an ipsec inside connection. I have the following config and a few questions I´d be very happy to get an answer for...

  Backup on the interface outside the security0 Server

  Client safety within 100 interface

  The client IP address is 200.200.212.194

  backup server address is 200.200.202.201

  I want to implement a VPN client connection to the inside interface, and therfore have implemented the following configuration.

  external IP 200.200.202.200 255.255.255.0

  IP address inside 200.200.212.193 255.255.255.192

  access-list 100 permit host 200.200.202.201 ip 10.3.3.0 255.255.255.0

  IP local pool privada 10.3.3.1 - 10.3.3.254

  Crypto ipsec transform-set esp-3des esp-sha-hmac RIGHT

  Crypto-map dynamic dynmap 10 transform-set RIGHT

  map mymap 10-isakmp ipsec crypto dynamic dynmap

  client configuration address map mymap crypto initiate

  client configuration address map mymap crypto answer

  mymap map crypto inside interface

  ISAKMP allows inside

  ISAKMP policy 10 sha hash

  ISAKMP life duration strategy 10 86400

  vpngroup address private pool PRIVADAGROUP

  PRIVADAGROUP vpngroup password *.

  vpngroup split tunnel 100 PRIVADAGROUP

  I have a few questions about this configuration maybe some kind soul able to respond.

  1. the VPN clients receive an address (10.3.3.1) for example through the IKE negotiation. When I ping my server from the client with the active VPN tunnel I assume the real package that passes through the wire has 10.3.3.1 a source address and a destination of 200.200.212.193 (endpoint the VPN and inside interface). Within IPSEC, the package is my real ip with a source 200.200.212.194 address (address of the real client) and a destination address of 200.200.202.201 (address of the backup server that I am trying to ping). If all this makes sense and is correct could you confirm the following point.

  2 when the PIX deencrypts the package and removes the IPSEC header I find myself with my IP packet of origin with a source 200.200.212.194 address (address of the real client) and a destination address of 200.200.202.201 (address of the backup server that I am trying to ping). I don't know if I need then the following configuration to allow the package to be transferred to the backup without NAT server:

  access-list allowed sheep host ip 200.200.212.194 255.255.255.0 200.200.202.0 255.255.255.0

  NAT (inside) 0 access-list sheep

  I was previously using the following configuration and it seemed to work but the more I think the less sense it seems to do as I´d wait for the SENATE to run on the dencypted package. I must be missing something or confused, or both.

  IP 10.3.3.0 allow Access-list sheep 255.255.255.0 200.200.202.0 255.255.255.0

  NAT (inside) 0 access-list sheep

  3. as a last and probably least I m pretty sure I don't have to line "isakmp key * address 0.0.0.0 netmask 0.0.0.0" when connecting with a VPN client software only. Somone can confirm that for me.

  I'm actually trying to get this to work remotely with someone else doing the actual work and we don't speak the same language.

  Any help to store my confused brain would be appreciated.

  1. No, it's the other way around. The real package that passes through the wire has the address IP of the PC (200.200.212.194) as a source. Within the IPSec packet is allocated 10.3.3.1 as source IP address. When the PIX decrypts the packet, the outer header is removed, and the package has a source of 10.3.3.1 as it is sent to your server on the outside. The external server will respond to 10.3.3.1 so it must be routed to the PIX for her to work.

  Think of this as the normal instance with the PC to the outside through the Internet. A package from of and sent to 10.3.3.1 would never do to the original PC. The encrypted IPSec packet always contains the VPN endpoints real IP source and destination addresses. The decrypted original deck contains allocated as source IP and the actual destination as destination (usually also a private address) computer.

  2. This should make more sense now that you know the answer to 1.

  3. you don't need that if you have a "vpngroup password xxxx" command. This command «isakmp key...» "If there is no specific vpngroup key, or someone connects with a different groupname.

• VPN on PIX Newbie question

  Hello

  I need to create a site to site VPN, I have in mind a PIX 515e. Behind it is a network of win2k with a domain controller for authentication. Users of the remote site must be attached to authenticate to this DC via a VPN.

  The two sites to connect to the internet by modem cable and the remote site will have up to 10 users behind the PIX/VPN.

  Here are my questions:

  What kind of material PIX the remote site needs? A 501/506, or something else.

  Do I need a VPN concentrator, etc. to the head of line?

  How the hell i make it work?

  Sounds simple right? I appreciate a lot of help because I am a little confused. Thanks in advance.

• Configuring PIX Cisco Question - very limited info. Sorry!

  People,

  Have been put to me a quetsion on a Cisco PIX (I don't know what model it is) who I know very very limited. The person asked me the question, is to help someone else! I apologize in advance for the lack of information here, but Im hoping that someone who has expertise in PIX experts will be able to diagnose the problem, or ask the question to the bottom of the chain to address this problem. The question they asked me: -.

  "Can't get NAT works correctly between the demilitarized zone and other ports.

  I know that it is very skectchy, but because I'm not a firewall or security Im not sure what I want or what questions I need to ask. I have however a copy of the config, if someone can help, we'd really appreciate it.

  Config is attached.

  I think that the above is not a problem.

  However, here it is a question;

  static (dmz1, external) 20.20.20.252 switch1 netmask 255.255.255.255 0 0

  static (dmz1, external) 20.20.20.22 switch1 netmask 255.255.255.255 0 0

  I think it should be;

  static (dmz1, external) 20.20.20.252 switch1 netmask 255.255.255.255 0 0

  (dmz1, external) 20.20.20.22 static nlbweb1 netmask 255.255.255.255 0 0

  Let us know if this can help,

• Wiring question: PXI-2501 1 wire 48 x 1

  Dear friends,

  I need wiring help.   I have a setup of the PXI-2501 for 1 wire 48 x 1 with a block of connection TB-2065.   I have an analog signal entering the block I want to switch between 5 different LEDs.   The incoming analog signal has two sons (positive & GND), and my Bank of LEDS has 6 wires (5 separate positive & a shared GND).   I have reviewed the documentation section 'NI Switches Help' 'topology, NI PXI-2501/2503 1fil 48 × 1 Multiplexer', but he has not quite figured it.   Can I connect my two ground wires and then connect the rest like this?

  analog input

  + 1-> the Terminal 27

  output LED Bank

  + 1-> terminal 67

  + 2-> 66 terminal

  + 3-> terminal 65

  + 4-> terminal 64

  + 5-> terminal 65

  Also, should I be connecting GND wires on the block somewhere instead of themselves?

  Any help would be greatly appreciated...

  Thank you

  Zach Barnett

  Hello Zach,

  Try to move the analog input + 61 terminal connection.  You can a) connect your two ground wires or b) can connect the ground wires to the TB-2605 terminal block.

  The image below shows the resulting configuration if you connect the wires to the Earth to the terminal block:

  

  I hope this helps!

• Simple failover PIX LAN question

  Is - this (PIX 6.3) FO license that is sufficient for LAN-based failover to secondary unit or to be unrestricted? I can not find the exact answer on the Cisco Web.

  Marko

  Yes, Marko, FO license is sufficient for the minor unit. Primary should be allowed without restriction.

• PIX OSPF question load balancing

  I have a pix 515e with two default routes, via OSPF from two routers on the "outside" interface

  Route #2 is currently being preferred spending much more than the #1 router. There are thousands of destinations for traffic. These two routers are still NAT nat rfc1918 IP Internet (the pix doesn't nat)

  Can you get it someone please let me know how the PIX is load balancing? is it by destination IP address? is it something else?

  Thank you

  Joe

  TAC:

  "the PIX will be per destination load balancing instead of by package

  load balancing. The algorithm will look at the source and destination

  addresses. It is not 1:1 load balancing. Given quite different

  the source address and destination, the packets will reach more or less one

  spindle of 50-50 between the two next-hops. However, in the real world test

  with the same source and destination addresses, it may not reach the same

  load balancing. »

• VPN pix 515 questions

  Hello

  We strive to provide access to the remote client to a server on the inside interface. We have read a lot of topics similare, but still does not work. Can someone please take a look at our configuration and let us know what we're doing wrong?

  Our int are as follows:

  outside = 204.222.162.0

  inside = 192.168.1.1 - 254

  DMZ = 204.222.161.0

  Thank you

  Hello

  You must have a static nat translation for the internal server.

  static (Inside, Outside) netmask 255.255.255.255 0 0

  Then create an access list to allow access to the host (public IP) with port...

  ex:

  out_to_in list access permit tcp any host 1.1.1.1 eq telnet

  Apply the ACL to the external interface.

• R3 wiring question

  I had 2 GTS 450. in my pc. and it went wrong. So I had a 290 R9. but my diet wouldn't run it. so I had a psu 875 w and the new card needs a plau 6 pins and a connector 8 pin. as you can see from this picture it is attached to the 2 450 s. now I plug this one into the 6 pins and other pins in the plug 8. the box says must 150w 8-pole and 6 plug PIN must 75w?

  [IMG] http://i.imgur.com/xxgTOc8.jpg [LINE]

  You have my new card hooked up and it works? but I discovered that when I opened it on it had a card telling me a bios on the card switch. and he say for windows 8 and switch on the side and for windows 7 for more on early again the reverse... I looked at the other card. and it was fixed for windows 8 and higher. that should be the reason why it did not work. same duh the MSI tech didn't tell me to check it out.

• question about shun to pix

  Is it possible to have a user account specific on the sensor to connect and send commands on a PIX of shun, or are you limited to a generic connection with activate password?

  Thank you

  1) go to web configuration GUI on the sensor.

  (2) select the tab "configuration".

  (3) select 'blocking'-> 'logical devices.

  4. Enter username, password and enable password in the appropriate fields.

  5) go to "blocking devices", adds PIX as a blocking device.

  It should work. I do something similar through the IDSMC, but the configuration will be reflected on the individual sensors I described above. (Assume that you are on code sensor 4.x and the user name is valid for the PIX in question).

  I hope this helps.

  Kind regards

• Using VPN Client coming out behind a PIX

  As I understand it, a PIX can operate as a VPN endpoint for IPsec tunnels, or allow IPsec traffic to pass to the other endpoints behind him; My PIX is an end point, but there are a few users who wish to use the VPN Client to connect to outside points beyond the firewall.

  Is it possible to configure a PIX to two pass through IPsec traffic AND be an endpoint?

  On a related note, two customer software VPN hosts can connect to each other?

  Thank you

  Marc

  My pix company does exactly what you posted, there is lan - lan vpn, and we again establish vpn to other companies via a software vpn client.

  concerning the transmission of described video, it should not need additional acl or configuration assuming that there is no acl on the pix. a question must be noticed is that the other end (i.e. the end point of the remote vpn client) needs to nat-traversal since the local pix usually perform nat/pat.

  However, the vpn directly between two clients is not feasible as its name suggests (they are the two client).

• SSH Authentication: PIX-> RADIUS

  Hello. I try to have a [6.3.5] PIX firewall question a RADIUS server for authentication SSH users. The PIX is remote, if I'm afraid of losing access to it. :) My question is what commands can I enter if I am already SSHed in unity, such that the NEXT time I SSH in, PIX will check the RADIUS box for my user name / password challenge? Pleae help... Thank you!!!

  Hey Quentin,

  We can have this command, but it is not mandatory to have access SSH for the PIX.

  This command is used to verify the credentials allow RADIUS.
