• 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.

• PIX 520 running 6.2 (1); SSH session limited exceeded; cannot reconnect

  Twice now, one of my PIX 520 s did not allow new ssh or telnet sessions and displays the following message on the syslog server:

  PIX-4-315005% SSH session limit exceeded %. Connection request of #. #. #. # on the _interfacename_ interface

  I think I understand the basics of what is going on, but I am confused about how to get it for free, and why it has suddenly become a problem.

  Both times I went to a physical console (via the nice blue cable) session and used the ssh session disconnect # command. There are 5 numbered 0-4 connections.

  Both times that do not release the firewall to serve ssh again.

  Help! Anyone have any ideas?

  It is a known issue (CSCdy05681 and other I think), must be laid down in the code of 6.2 (2).

• PIX 520 model CO or MAKE

  Gentlemen

  Last night I was reading my release notes for my 16 MG ISA Flash card before installing in my PIX 520. The release notes indicate that I have to check if I have a 520 PIX "CO" or "MAKE". A worm show command does not reveal this? I have a small white sticker on the box that says "PIX 520" with no further details.

  How can I determine if I have one of these models 'CO' or 'DOING '. It is safe to assume that if she does not, I can go ahead with the upgrade?

  Also, I have 2 of these cards to 16 mg. I can put the two or is 16 Cape on Flash... I ask because I want to code ver 6.2.2. In addition to install PDM version 2...

  Thank you

  Kevin

  It usuallt you indicates on the label, but you can tell by the serial number as well.

  A0 PIX are between 18005000-18013334

  B0 PIX are between 18013335-18015503

  C0 PIX are between 18015504-18025676

  D0 and E0 are 18025677 and more

  Note that there may be a 44 in front of these numbers on your serial number label.

  Also note that the installation instructions say the 16Meg card is not compatible with the PIX of C0 (or at least he used to say that), it won't and you can install this card without problem.

  Make sure that you first remove the existing 2Meg card, otherwise the PIX will not work. The card is one without the external connectors on it at the back.

  You can only put one of these cards in, no need for both. You will be able to load 6.2 (2) and PDM with no problems.

• 3DES throughput of PIX 520?

  Hello

  Anyone know what is the PIX 520 3DES throughput? (No VPN accelerator card)

  Thank you

  Hi Oneill,

  As PIX520 EOL, it took me a bit of searching to find it, so I hope this helps you...

  http://www.Cisco.com/warp/public/cc/PD/FW/sqfw500/prodlit/963_pp.htm

  Software and hardware encryption

  Version 5.0 (1), with the addition of the appropriate encryption key, provides encryption based on the software for THE (56-bit) and 3DES (168-bit), as support for the acceleration OF only using the PL2 existing (PrivateLink) map. Users can expect to see a minimum of 10 to 20 Mbps of throughput for 3DES connections and 30 to 40 Mbps of throughput for using encryption based on PIX software. Customers who use the card PL2 can expect to double their throughput OF. NOTE: The PL2 card does NOT support 3DES encryption. In addition, the low number for above mentioned 3DES throughput is for the 515 PIX with a 200 MHz processor, and the high number is for 520 PIX with a 350 MHz processor.

• 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?

• PIX 520

  Can I allow outside users to connect to an IP address on the inside with the help of NAT I need to establish a connection with a DCOM application and apparently it does ' t work with NAT.

  Thank you

  To establish a connection between the external and internal interface interface, you need a static and an ACL. The static method CAN map the IP address of the host to himself, effectively bypassing NAT, but this means that the internal host must have valid Internet a routable IP address.

  For example, assume that your internal host has a 209.1.2.3 Internet address, your config might look like:

  > static (inside, outside) 209.1.2.3 209.1.2.3 netmask 255.255.255.255 0 0

  > list of allowed inbound ip access any host 209.1.2.3

  > interface incoming group-access outside

  Of course, you should make sure that 209.1.2.3 is routed to your PIX.

• Statements of NAT

  We have a new ASA 5510.  We are not sure of the basic configurations.   We want to use the ASA as a firewall and VPN.  For VPN, we go to the configuration for VPN client group policies.  There is a router between the ASA and internal networks.  Here is the basic configuration.  Do you see something wrong?  Is there something else that we need the facility regarding the routing?

  1. the external IP address is 66.102.7.17, netmask 255.255.255.248 gateway 66.102.7.22.   Is that what we would go into the outside interface?

  interface Ethernet0/0
  nameif outside
  security-level 0
  IP 66.102.7.17 255.255.255.0

  2. we want NAT IP address private to each public IP address.  Public IP addresses are 209.145.25.1 - 209.145.25.62, subnet mask 255.255.255.192.   Here are the correct declarations of NAT?

  static (inside, outside) 209.145.25.1 192.168.100.1 netmask 255.255.255.255
  static (inside, outside) 209.145.25.2 192.168.100.2 netmask 255.255.255.255
  static (inside, outside) 209.145.25.3 192.168.100.3 netmask 255.255.255.255
  static (inside, outside) 209.145.25.4 192.168.100.4 netmask 255.255.255.255
  static (inside, outside) 209.145.25.5 192.168.100.5 netmask 255.255.255.255

  3. This is the instruction to the road outside.  Is it correct?  The 66.102.7.22 IP address is the default gateway of 66.102.7.17, which is the external interface of the ASA

  Route outside 0.0.0.0 0.0.0.0 66.102.7.22 1

  3. given that the external of the ASA interface and public IP addresses are on different networks, we need another statement of course?

  Thank you.

  Diane

  Diane,

  Everything is OK with these exceptions:

  1. change the mask

  interface e0/0
  no ip add
  IP 66.102.7.17 255.255.255.248

  2. as public IP addresses are on a different subnet of the IP outside the ASA, you must ensure that the ISP knows how to send
  the ASA traffic intended for these IPs.

  Hoping to help.

• Unable to BREAK/ESC to switch to Monitor Mode on the PIX 520

  Hi all

  I'm moving to PIX704.bin... I tried Copy TFTP FLASH and it fails with a space. So when I try to recharge, I'm never invited to the command BREAK/ESC. Here is the result:

  Reset...

  Cisco Secure PIX Firewall BIOS (3.6)

  Flash = @ 0 x 300 i28F640J5

  Read 1962496 bytes of the image of the flash.

  Is it possible that the BIOS is too old? Any help would be greatly appreciated...

  Glad it helps. On the 520, you use a boot disk not the break sequence. Normally, you would use the tftp command to load the most recent versions of the firewall operating system anyway. You can see the following link 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.

• PIX 520 IP Addressing question.

  My 520 has 2 Ethernet ports. I can ip outside interface (E0) 170.1.111.1 255.255.255.255 and IP inside (E1) 170.1.111.2 255.255.255.0. If this is not the case, how can there be two interfaces on the same subnet. I want to use the 520 as a firewall in an enterprise WAN packet filtering. Inside boxes will have an ip address in the range of 170.1.111.0.

  These are not my real IP addresses *.

  Its called multinetting, if I'm not mistaken, and no, you can not multinet, i.e. having same subnet on different interfaces on the same device.
