PIX 515E Version 6.1 (4) a fall port scans
Hello
Is it possible to configure the PIX he abandoned scan port behind the firewall host guests? I have a combustion chamber watchguard when I scan a crowd behind him, he will drop all connections from computers that performs the analysis of ports. The PIX it?
Thanks for any help!

You can use the commands 'IP audit' to activate the ID feature in the PIX. Order with examples is here:
http://www.Cisco.com/univercd/CC/TD/doc/product/iaabu/PIX/pix_62/cmdref/GL.htm#1027034
Signatures that will search the PIX are here:
http://www.Cisco.com/univercd/CC/TD/doc/product/iaabu/PIX/pix_62/syslog/pixemsgs.htm#1032267
That said, the PIX will not be able to detect a port scan, and then automatically stops all packets from that host. With a network of system ID the PIX can be used to run packages for more than 300 different types of signatures, but in itself it checks only about 59 signatures (detailed in the link above) and those who are in general only the signatures of a package type.
Detect port scans is best left up to a good device IDS which aims to do and let your firewall to firewall.

This PIX has a failover license only (FO).
Problem is that we cannot ping inner harbor, if we do not switch light, but this is a unique machine. Here's another message once we turn on the switch:

Please help solve this problem. I wonder if we buy the wrong license? Thank you very much.
you have in your possession a PIX failover. That's why says in the "sh run".
This device is intended to be used only as a failover for a live device. It will work as a live PIX, but behave badly. It is cheaper than a PIX with an unrestricted license, as it is not intended to be used as a standalone device. Check with the one that you bought to get the situation sorted.
Good luck

Try to add the "isakmp nat-traversal" command to your PIX. I suspect what happens is that Remote LAN users is translated to a single IP address as they pass through the DSL connection. I also assume that the machine doing the translation has a capacity of IPSec passthrough. Linksys routers would be a good example of this type of NAT device that allows IPSec pull-out.
If that's the case, that a single VPN connection will be able to operate both. The above command will turn PIX detect clients that are located behind a NAT device, and then try to configure the VPN sessions in UDP packets and so to work around the limitation of NAT and IPSec passthrough device.

I am installing a PIX 515e with an ADSL router. I have all the IP addresses for the router etc. I'm trying to connect to a network on the interface internal of the PIX. (Please bare with me as I am new on the firewall!)
I ping the network firewall, but I can not access to the internet. The initial configuration for the PIX documentation implies that by default, it has access form the firewall but no! I'm obviously missing something here, i.e. of Thompson the network to route requests through the firewall interent! ???
Sorry to be so simplistic but I'm learning all the time!
Thanks for any help.
Robin
After you enter the acl to allow ping, can you ping now?
Watch newspaper reveal something?
For DNS and testing, create a static on the PIX for your DNS server. For example "x.x.x.x (indoor, outdoor) static 192.168.0.x netmask 255.255.255.255" where x.x.x.x is a public IP address and 192.168.0.x is your dns server. Then let the outside to your DNS server dns - "access-list 101 permit host udp/tcp host x.x.x.x eq 53 z.z.z.z ' where z.z.z.z is a public dns server (or use one for testing) and x.x.x.x IP NAT'ed to your dns server. See what is happening, look in your journal.
What version of PIX you run.
Let know use.

Hi hiren,.
See the answers below:
#Router inside the IP - 172.16.29.1 (inside property intellectual as it is very critical that cannot be changed)
When you upgrade the PIX router inbetween and your switch, you must put the PIX inside IP like 172.16.29.1 and change the router within the subnet to someother pool. Do the PAT on the PIX, rather than the router.
Outdoor #Router ip - what ip should I use? (I tried with 1.1.1.1 255.255.255.0)
Router outside the property intellectual property will be that given by the ISP... The ISP would have given a public IP address for the WAN link. This cannot be changed.
#PIX outside intellectual property - what ip should I use? (My ISP IP?-j' tried with 208.144.230.197 which is currently outside of my router)
PIX outside IP must be comprehensive. ISP would have given you a LAN subnet. Use it. In this case, inside the interface of the router has an IP address from that subnet even...
#PIX within the intellectual property - what ip should I use? (I tried with 1.1.1.2 255.255.255.0)
PIX inside must be 172.16.29.1, which will be the default gateway for all PCs. If you change this subnet, then the PC should have an IP address on the same subnet that has decided.
Connection ISP #My is directly from the ISP GW to an ethernet cat 5 on my router VLAN
didn't get it... is that on the internet router or switch?
#I would allow www, FTP, web-based like Yahoomail... etc... & Messenger services
If all these must be permitted from inside to outside, you have not open anything... by default, all traffic to the inside outside is allowed (except if you put a list of access denied)...

VPN with ASA 5500 VPN with PIX 515E vs
I wonder what are the differences between the use of an exisitng PIX 515E for VPN remote users as appossed to acquire an ASA 5500 VPN remote users? Information or advice are appreciated to help me lean toward one or the other.
Craig
According to the version of the code that you run on the PIX on the PIX or ASA VPN features must be the same. So if the choice is not based on differences in features, what else would help guide the choice? You can consider if the existing PIX has sufficient resources to add the extra processing VPN load or if you should put that on another box. You might consider that the PIX is an older product range, and his end is near, while the ASA is the product that is the strategic replacement for the PIX. Given a choice I probably prefer to use a technology newer than the old technology. I also believe that the ASA will give you more choice of technology to go forward (a way of better growth) while the PIX provides current capacity but no path of growth.
On the other hand, there is the aspect of consider that using the existing PIX does not need not to buy something new and ASA would be an expense you have to cover in the budget. And for some people the budget constraint is an important consideration.

I got some new PIX 515E security infra-red and I had sex 2 questions about everything I tried. I installed a 5 port switch inside and cannot ping anything from the console. I have a computer on the switch, and he is able to ping other devices on the switch, but not the PIX.
What I find strange is that when I try to ping from the inside interface on the PIX of one inside computers, PIX displays the MAC address of the computer inside in the arp table.
My goal is to upgrade the PIX to ver7.0 but I can't do so until I can solve this problem.
Here are some information among the PIX.

Hi M8,
Your firewall has a license of FO, you must enable this device to be able to see it.
Run the command:
active failover
With this command, the device turns into the 'Active' from a perspective of failover state. It will work after that.
See you soon.
