Question STATIC pix
I have a static mapping for my mail server (public to private IP address) and I was curious about the behavior of a static mapping. I got just as much as to process the incoming packets. But what happened in outgoing traffic from the server? The pix to see a package of outgoing e-mail and insert this public static address as the IP source address?
Yes, he does. It uses the static statement as it would NAT, except that it always uses this external IP address assigned instead of pulling an IP from the NAT Pool address.

I have installed a pix 515 at home on my broadband for the test connection. I was wondering if it is possible to use the static command to map an internal on the dhcp address assigned by ISP. I have reverse DNS client installation to map the dhcp WAN attributed to a public dns server address.
Example:
outside interface0
Interface1 inside
IP address outside dhcp setroute
inside the 172.16.0.1 IP address
IP route 0.0.0.0 0.0.0.0 dhcp
Thank you
Assuming you have something like:
> nat (inside) 1 0 0
> global (1 external interface)
for your outgoing traffic, you can proceed as follows for incoming traffic:
> static (inside, outside) tcp interface 80 172.16.0.2 80 netmask 255.255.255.255
It maps all TCP port 80 package intended for the PIX outside interface to the internal server at 172.16.0.2 on port 80. The keyword "interface" means interfaces external IP address. You can add as many of these port mappings as you want. The ports must be the same either, you can map port 80 to port 345 if you wish.

Hi all
We just bought a PIX 515E and try to use it, but got a number of questions. Here's the NVA of show:
PIX-151st #show version
Cisco PIX Firewall Version 6.3 (1)
Cisco PIX Device Manager Version 3.0 (1)
Updated Thursday 19 March 03 11:49 by Manu
PIX-515E up to 5 hours and 15 minutes
Material: PIX-515E, 64 MB RAM, Pentium II 433 MHz processor
Flash E28F128J3 @ 0 x 300, 16 MB
BIOS Flash AM29F400B @ 0xfffd8000, 32 KB
0: ethernet0: the address is 000f.2457.4b12, irq 10
1: ethernet1: the address is 000f.2457.4b13, irq 11

Failover: enabled
VPN - A: enabled
VPN-3DES-AES: enabled
Maximum Interfaces: 6
Cut - through Proxy: enabled
Guardians: enabled
URL filtering: enabled
Internal hosts: unlimited
Flow: IKE peers unlimited: unlimited
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:
PIX-515E # config t
WARNING *.
Configuration of replication is NOT performed the unit from standby to Active unit.
Configurations are no longer synchronized.
PIX-515e (config) #.
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

Question of PIX network diagram...
This is a lame question, so I apologize in advance.
On network diagrams, when using the provided Cisco PIX stencil, is there a way 'just' to face the stencil. I mean, the arrow must face in the outbound direction, with the vertical line closer to "external"?
again, I apologize for what is lame...
Yes, the vertical line or I would say that the wall - as the form should be placed on the external interface.
for example
www-(|)<) ---="" inside="">)>

A question of pix port forwarding
I don't have a single public ip address. It has been used by the external interface. How can I allow outside access to the internal host
Web server?
According to Jack Ko's post, you can also use the keyword: interface on your static, that is, if you only have a single public IP address and this IP is used for the PIX outside interface:
public static tcp (indoor, outdoor) interface 80 80 netmask 255.255.255.255 0 0
-or-
To access SMTP:
access list 100 permit tcp any eq smtp host
Access-group 100 in external interface
public static tcp (indoor, outdoor) interface smtp smtp netmask 255.255.255.255 0 0
Yet once, save with: write mem and also issue: clear xlate
Hope this helps,

I have a client with a 515 cisco pix. Is it possible to have 2 separate configs on the pix and power quickly select what config you want to begin? My client had problems lately with his main ISPS who happens be the fastest connection between the 2 and when it comes down there do intellectual property changes on the pix to perform the failover manually.
Ok..

Is it a question of Pix?
Hi guys,.
I got a 515E with Pix os 7.0. This work of Pix as a border between my edge router and my network firewall internal.
Some of my clients inside require a SMTP via SSL connection to external SMTP server. I opened all the ports on the pix, but always in vain. Finally I tried to get one of the customer's internal network in order to access all THE ports on the outside. Right when I did, this particular client should be able to access all the services on the Internet. But the same error came out with the number SMTPoverSSL. Im sure it is the problem of the PIX because I had tried out the PIX and connect directly to the router, it works!
Someone out there of experts who can advise me? Thanks in advance.
Kind regards

If you do an inspection policy, try to remove the "inspect esmtp" of your
class inspection_default
Kind regards

Hello
Understand that there are some parameters of time-out on pix. Need to check:
1 TCP timeout 01:00. In my view, that it is idle time-out. PIX send TCP reset after timeout?
2. 03:00 timeout Xlate. Is - this time out inactive?
PIX send TCP reset after timeout?
Yes, according to the information in the original post, the PIX should remove any xlates that has been inactive for 3 hours. Once these are removed, the need of xlates should be re-established a connection to occur.
Does that help?

Question of pix cannot be changed
I placed a series of photos in a collage in photoshop. I've never had this problem before, but none of the pix are editable. He let me use the eraser on them. What have I done wrong?
No. I asked if your image was of 32 bits, and it is not.
I'm pretty confident that your layers are smart objects (you can tell by the icon small mini document at the bottom right of the layer icon in the layers panel). You cannot delete dynamic objects. You must rasterize them and then erase them or create a mask layer for them and paint on which to erase them.
http://help.Adobe.com/en_US/Photoshop/11.0/WSCCBCA4AB-7821-4986-BC03-4D1045EF2A57a.html
If you have text layers (with the "T" icon in the layers panel) in the doc, these also cannot be erased and you will have to do the same for them, rasterize and then delete, or create a mask and black top to 'clear' the paint layer.

Question about the operation of the command "static"...
I have an obligation to protect a single system using maximum connections embryonic tag on the end of the command "static." However, the subnet of class-C all this machine is underway and is already covered by a large static for the whole subnet.
Question: Static commands like routing in the IOS commands, where the itinerary trumps the more generic road? See--->
If I have a static which publishes 10.1.1.0 (class-C), but I put an another static, with * parameters * for 10.1.1.27/32, you take effect?
-Alex
From my understanding of what you're trying to accomplish, I think you would want the opposite--static specific for 10.1.1.27 should be higher in the order than the more general 10.1.1.0 static. In this way, if an xlate must be built for the 10.1.1.27 host, specific static will take it. If the xlate is for something else in the 10.1.1.0 subnet, it will bypass the specific static and hit the more general one. Make sense?

ASA - impossible to configure dynamic IP distance to central public static IP VPN
Hello
I'm trying to set up a VPN between an ASA5505 on remote Central with static IP and an ASA Site connected to a router with a dynamic IP address.
I tried tp follow the example site named Cisco "PIX / ASA 7.x IPsec dynamic to static PIX to PIX with NAT and VPN Client Configuration example" (http://cisco.com/en/US/products/ps6120/products_configuration_example09186a00805733df.shtml), but it does not work.
The problem is that when I generate traffic, the ASA central got the message (Remote_Dynamic_IP is just to remove the real IP):
01 Jul 10:24:24 [IKEv1]: IP = Remote_Dynamic_IP, error during load processing: payload ID: 1
01 Jul 10:24:24 [IKEv1]: IP = Remote_Dynamic_IP, Removing peer to peer table has not, no match!
01 Jul 10:24:24 [IKEv1]: IP = Remote_Dynamic_IP, error: cannot delete PeerTblEntry
01 Jul 10:24:31 [IKEv1]: IP = Remote_Dynamic_IP, error during load processing: payload ID: 1
01 Jul 10:24:31 [IKEv1]: IP = Remote_Dynamic_IP, Removing peer to peer table has not, no match!
01 Jul 10:24:31 [IKEv1]: IP = Remote_Dynamic_IP, error: cannot delete PeerTblEntry
The remote and remote router asa are connected on a network with fixed addresses, i.e.:
dynamic_ip--> router<--static_ip(E.F.G.1)--static_ip(E.F.G.2>--static_ip(E.F.G.1)--static_ip(E.F.G.2>
