  Thank you.

  No problem for version 6.3 (5) don't forget but version 7.0.

  Release notes:

  PIX 520 requirements: 16 MB (Some PIX 520 units possibly an upgrade of memory because the older models had 2 MB, although newer units have 16 MB)

• 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).

• statements of nat on my PIX 520

  I have the following two statements on the config of my PIX 520:

  NAT (inside) - 0 100 access list

  NAT (inside) 1 0.0.0.0 0.0.0.0 0 0

  I understand that my predecessor built our Access-list 100 as tunnels for our VPN to our customers. But I don't know what is the purpose of the 2nd NAT.

  Pls help...

  Education of a nat 0 specifies addresses that will not be translated.

  The nat statement 1 by 0 all indicates that any address will lead to a global address. (with the exception of nat 0)

  Access-list 100 should be your networking source and destination for the vpn.

• 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...

  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.

• 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.

• 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...

  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.

• 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 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.

• Misfortunes of brush model: how to make the corners at the height?

  As you can see, theres a HUGE gab between the tile of angle and line tiles - you know the reason for this?

  

  Your linear tile is broad of five symbols. Maybe Illustrator puts white anywhere that does not have the design of the scale of five. Have your tried a brush that has only one of these forms? Look at the results with these two brushes built in haste: (top five circles by link, at the bottom, a circle by link)
