Port Fowarding PIX 501
Is it possible to forward port 80 to internal ip on a PIX 501?
I have a PIX 501, which made PAT / internal DHCP for my network. I want to forward all queries [80] http to an internal web server.
Thank you
Sepyh...
You can use port forwarding to get there.
Here is an example configuration:

Hope this helps,

I would like to access my PC location xyz. How can I open port 22 access to my pc. I use pix 501.
Can anyone provide commands to open the port so that I can access my pc.
Thank you
totally agree because only 3 commands are needed.
list of allowed inbound tcp access any eq 22
public static tcp (indoor, outdoor) interface 22 22 netmask 255.255.255.255 0 0
clear xlate
However, all of these commands are missing in the config you have posted.

I try to get my PIX 501 to forward traffic on port 1412 with TCP and UDP to use Direct Connect, and the problem I have is I can connect to a DC hub, but cannot establish connections with users.
I added the following to the default configuration from the factory with a partial success:
outside access list permit tcp any host 192.168.100.20 eq 1412
access-list outside permit udp any host 192.168.100.20 eq 1412
public static tcp (indoor, outdoor) interface 1412 192.168.100.20 1412 netmask 255.255.255.255 0 0
public static tcp (indoor, outdoor) interface 1412 192.168.100.20 1412 netmask 255.255.255.255 0 0
In the debug log set to the access list I rule this type of errors:
Deny tcp src outside other.users.ip.addr/3099 dst within the my.public.ip.addr/1412 by access-group "access_outside_in".
TCP request discarded outside my.public.ip.addr/45961 other.users.ip.addr/2362
I'm quite lost as to why it does not work when I think it should. I tried several ways, opening of port ranges and no chance for a transfer of the port sucsessful.
You can change you, outside the ACL to the following:
outside access list permit tcp any host eq 1412
access-list outside permit udp any host eq 1412
outside access-group in external interface
Save again with: write mem and also issue: clear xlate
I would like to know if it works.

Hey guys,.
The switch integrated on a PIX 501 will freely forward traffic between devices plugged into it, as long as they are on the same subnet? I assume that the answer is Yes. If so, is it possible to isolate one device other network traffic using the PIX only? I can t think in a certain way, but I'm not a guru PIX, so I figured that I d ask Mr. thanks a lot for any information that you may be able to provide.
Do you hear them VLAN private?
If so, then 'NO', it is not possible.
There is no options at all to things like private VLAN on a PIX 501.
Connect a Switch which suports as suppoorts this kind of features and a port of the switch to the pix.

PIX 501 in the firewall of the Web server
Hello
At the suggestion of a colleague, we bought a firewall PIX 501 to protect our new Win2003 web server and a UNIX/Oracle DB server.
I've never worked with before firewalls.
Our servers are located in a cage at the ISP and belong to us. There are only two servers providing web site. I have read the documentation in the Getting Started book and it does not answer my question.
We have 2 web sites with different IP numbers on our web server. Let's say 140.5.5.4 and 140.5.5.5. I understand that I have will redefine the numbers with the firewall (192,...) but I do not understand how the routers at the ISP will be able to route requests for two websites to the firewall when it has one IP number, say 140.5.5.1?
Any help is appreciated.
Thank you, Jerry
Jerry,
what you are referring is called port forwarding. Whether you a PIX with a public IP address 12.1.1.1 and your web servers are respectively and 12.1.1.2 12.1.1.3. Port forwarding is really a 2 step process:
* a static translation of the public IP address of the PIX (12.1.1.1) at the address of the web server (12.1.1.2)...
static (inside, outside) tcp 12.1.1.1 12.1.1.2 www www netmask 255.255.255.255 0 0
* an intermediate statement basically "all web requests should be allowed in the pix outside of the interface"...
driving permit tcp host 12.1.1.1 eq www everything
Here is a link that will help you to clarify this point:
www.Cisco.com/warp/Customer/707/28.html
This should help you get started. Regarding the basic configuration, it takes config examples on the Cisco site, if you have access CCO.
Let me know if it helps.

My PIX 501 switch stopped working or has failed. The PIX is 10 months old. This is the second time I've seen that happen. The first time I sent it fixed by repair out of warranty, but they couldn't fix it. They said it was a chip owner they could not get from Cisco.
In any case, the unit has power. I am able to connect through the console and the WAN via SSH port. It is fully operational with the exception of the portion of the switch of the device.
Has anyone seen this kind of problem before? I've never seen a switch or a hub spoil. It's the second PIX to go wrong in the same local area network installed. PCs and servers all continue networking function wise, so connected to another switch.
Is that what I can do about this problem?
Thank you
Vince
Vince,
It depends on what type contract you have. You can open a TAC case and they will let you know the track.
Let me know if you have any questions.
Please mark this topic as resolved, so that others can benefit from.
Kind regards

Place a FIOS for VPN router behind PIX 501
I have a Verizon FIOS internet connection and one of their routers wide wireless broadband, and this is a configuration of base completely... their router DHCP and firewalls, and the connection has a dynamic address. I would put the PIX 501 behind the Verizon router as one of its clients and make the VPN PIX of other PIX 501 at other locations, such as my entire network has access to remote networks.
Is this possible, and if yes, any who could some suggest configurations (how to address internal and external, static routes ports that may be required somewhere, etc.)?
Thanks for any help.
When installing my FiOS, I had already asked that it be installed on the Ethernet cable. Don't know they need to do something for you to spend the coax to Ethernet.
The best way to test it would be to find the Media Converter (follow the coaxial cable between your FiOS router to the demarc and there should be a box with a coaxial port, some phone Sockets and an Ethernet port). If you unplug the coaxial cable and plug a laptop computer on the Ethernet port, see if your laptop takes a public IP address. If Yes, then you just have to run to your PIX501 Ethernet cable and you should be ready.
Just to note that Verizon, according to your region, reserved DHCP assignments. This means that you may need to call Verizon and ask them to release the previous assignment of DHCP-MAC addresses. I had this happen recently. They must release the assignment then your PIX will pull a new IP address and they will book your new IP - MAC address assignment. They do this to speed up the connection to a cold start time on the router.
Basically, they are filtering by MAC address, but rather through a sticky ARP where they clear the entry, and then the next device that connects records his MAC address and then only that device is permitted to connect to this leg of the cable. So there is a bit of work you have to do, but the most difficult part would be sitting on hold waiting for a tech, if you call to Verizon.

default configuration of the pix 501 past recovery/restoration
You need to reset the PIX 501 (lost password). I tried the password recovery instructions and accesses the monitor command by using the connection of the console, but cannot get the file to be transferred using tftp (ping command also expires).
1. in case ordering interface be set to 0 or 1 (I used 1)
2. the order of the address I was using 192.168.1.1
3. order the server, I was using the IP address of the tftp server
4. entry door? (Which is the PIX or the computer)?
5. in addition to the blue console cable that if all other cables should be connected and which ports.
Thank you
I'm guessing you already have this document:
I would like to use the default value inside of the interface of the 1. Connect a standard ethernet cable to one of the Interior ports on the PIX and the other to your PC that has the server tftp on it of the interface software. Make sure that you see a link on both ends light. If not, take this cable or save it if you think it is a crossover cable. If you set the PIX address to: 192.168.1.1, then I would set my tftp server address: 192.168.1.2 or something in the same subnet. In this way we will not care what is the gateway address. No need to let pesky routers get in the way, when we're down!
Since you asked the question 5 above, I'll explain. You should have a console cable connected, it seems do you since you can get to the monitor > prompt. You'll also need an ethernet cable plugged in a PC running a server tftp with the IP address: 192.168.1.2 3Com made a server tftp really good F * R * E * E.
http://support.3Com.com/software/utilities_for_windows_32_bit.htm
Select the last file in the list. Make sure you get that file recovery of password for the Cisco link above for the PIX OS version you are running. Configure the tftp server to point to the directory containing the PIX password recovery file and you are ready. Good luck, Derrick

Hello
I am considering the implementation of a vpn pptp on win2k server behind a pix 501 firewall (+ nat) with only 1 static IP address. I will also have to have at least 2-3 Terminal Server client connected simultaneously.
The Terminal Server service will pass through vpn tunnel.
Can this be achieved? A local Tech told me that I need at least 2 IP addresses.
Thank you
Mike
For Terminal Server services, you can do it with just an IP address that is assigned to the external interface of the PIX, just create a static mapped port to port 3389 thru peripheral inward.
For PPTP, you must however an IP address separate, different from that assigned to the PIX outside the int. This is because PPTP uses two TCP/1723 and GRE protocols. You can create a static mapped ports for TCP/1723 through the PPTP server, but you can't do it for the GRE. This is because GRE is not a TCP/UDP protocol, it is located just above IP and has therefore no port number to map through. You need an IP address unique address and card. You config should look like this:
list of allowed inbound tcp access any host 200.1.1.1 eq 1723
list of allowed incoming access will any host 200.1.1.1
Access-group interface incoming outside
public static 200.1.1.1 (indoor, outdoor) 10.1.1.1 netmask 255.255.255.255
where 200.1.1.1 is your second (different from the PIX off int) routable IP address 10.1.1.1 is your PPTP server inside
If you only want to use an IP address, why don't the PIX not set itself up as a PPTP server and put an end to your connections on this. The PPTP client end simply on the PIX outside IP address, and you will not need all the others.
See http://www.cisco.com/en/US/products/hw/vpndevc/ps2030/products_configuration_example09186a0080143a5d.shtml for more details.

Hello
I went through the ongoing discussion. The pix configuration should be fine for now according to suggestions. The problems seems to be on the server. If it is a new installation of windows, then there is an option not to accept requests that are not local network.
If you want to check if pix allows connections and then when you telnet to port 25 of the outside, just run the xlates control.
SH xlate and it should show you a translation for the inside host. More than a quick test if pix allows traffic is to check 'sho-outdoor access list' and see if the counters are increasing.
Hopefully this should help you.

Hello
I have a pix 501.
It gets the IP address of the ISP using PPPOE.
If I have an e-mail inside server can I still have the email NAT for this device.
I did before NAT on mail servers where I have a breakdown of the intellectual property of PSI.
In this scenario, I have 1 IP (he doesn't) outside.
Can I allow other services too although I have 1 IP address
John
The config is OK, but it might be better to replace the fixed IP address in the access list and the staic by a dynamic.
1. you have configured:
outside_access_in list of access permit tcp any host XX. XX.XXX.XXX eq ftp
Access-group outside_access_in in interface outside
static (inside, outside) tcp XX. XX.XXX.XXX ftp ftpserver ftp netmask 255.255.255.255 0 0
2 - I would like to replace this with:
outside_access_in tcp allowed access list any interface outside eq ftp
Access-group outside_access_in in interface outside
public static tcp (indoor, outdoor) interface ftp ftpserver ftp netmask 255.255.255.255 0 0
The advantage of this configuration is that if the IP address changes NAT and access list won't automticly too.
3 - you need a CLEAR XLATE after have changed you the NAT settings.
clear xlate
Note that this will reset all connections.
4. - use a dyndns or no - ip client so that when you connect on the Internet you just have to know the DNS name, and if the IP address changes the client will update the DynDNS server.
See:http://www.no-ip.com/downloads.php
5. - are you sure that your ISP Internet service provider allows ftp, smtp, and http? Many providers to block the ports for non-commercial DSL connections!

Pix 501 for Small Business SERVER 2003 configuration problems
I am new to cisco equipment. My company recently purchased a firewall of Pix 501 unlimited number of users, it is connected to an internet connection by cable with a dynamic ip address. Internet works fine and so the dhcp server.
I have a Windows 2003 Small Business Server on our network. I need to configure the firewall to forward ports on the SBS server for remote web workplace.
Also about a week ago I lost connectivity to the GUI of PDM via my web browser. Telnet and console work perfectly well.
I enclose my config file.
Any help will be appreciated. Thank you
Ed
FIRT off, you do not have a group-access instruction set for one of your ACL. This means that you have blocked all inbound traffic. You also have your incorrect static instructions. You can start by cleaning your config and enter the correct commands, you should be able to stick to your firewall config mode:
No list will host 192.168.1.1 acl-enabled access 192.168.1.1
no access list acl_outside not allowed tcp any any eq www
no access list acl_inside not allowed tcp any any eq www
no access list no incoming icmp permitted any one
No list of permitted no inbound tcp access any host 24.50.241.113 eq https
No list to access acl - permit gre 192.168.1.1 host 192.168.1.1

Help the PIX 501 - cannot access startup.html
I'm new to the network and has received a job to configure the PIX 501 firewall.
The fact is:
We use IP table rules as a firewall on a linux machine. My pc is connected to a switch. So I use the yellow network cable to connect the port of the Pix 501 0 to the port in the switch. Then I disconnect my pc of swich cable and plug into the port of the Pix 501 1.
My pc is to use a static ip address before. I try to change to automatically get an IP address, but it will not work. So I changed the setting and use the IP address originally. Pop up message network connection icon says that the local connection is enabled. But when I try to ping 192.168.1.1, request time-out. Also I can't acess the https://192.168.1.1/startup.html.
I have a look at Books Online cisco and shootings of disorder, but most of them talk about the configuration or more advance features. I'm still on the very basic level to try to connect to the firewall.
I hope someone can help me. All ideas and questions are welcome. Thank you.
Your IP address should be fine. You do not want to have the PIX connected to your local network, even if you have the Linux firewall as well as this will cause a conflict. Keep the PIX the LAN for now. Your DNS configuration will have no effect because the url you are trying to reach is based on the IP address and not the domain name if your PC has nothing to look for.
You have to check the cable that you use - if your PIX has only an 'inside' interface, then you must use a crossover cable. If he has four so it's built in switch for a straight cable will be fine. Is what PIX model?
After checking the cable - see if you can console in the firewall - use the blue cable that came with the PIX and set up a connection (hyper terminal) terminal with the help of 9600, 8, no 1. If you can console and then you can stick in a basic configuration you can get.

I'm putting in place an internet service for some members of the service here in Afghanistan. We use the commercial internet (provided by satellite) to a modem that goes into my firewall 501 pix.
Service that we bought gives us Ip 29, and now I just have it set up as such.
Modem gateway: 10.124.48.1
Outside the firewall: 10.124.48.2
Inside the firewall: 192.168.1.1
Global NAT pool: 10.124.48.3 30 (the rest of intellectual property s that are outside the package)
On the inside of the pool of the host: 192.168.1.2 -.33
DNS for inside customers: 192.168.130.30,.50
Everything seems ok, as I use the PDM software to allow all traffic ip from outside to inside (I know it isn't the safest to do thing ~ and the fact that I turned a firewall $ 700 to a router for $40). I can browse the internet, but it is really weird.
I.E.
I can ping msn.com and www.msn.com , and it resolves the twice,
But if I put msn.com in Internet explorer, it says cannot display the page, but if I hit the refresh like five times, it'll happen. If I navigate away from the page and then try to type in msn.com again (in the same window) I hit refresh 5 times, to get the next page.
But if I type in www.msn.com it just generally well upward.
Even when he says that the page cannot be displayed, I have her pinger running in background ~ so I know that I can get for it. Weird huh?
I also have a question about licenses. When I get the pix firewall information, it says inside hosts: 10 but he let's have me 32 s ip for inside hosts. Does this mean that I'm having problems when I have more than 10 users browsing through the firewall? Or is that what I have as many hosts ip s?
Thanks in advance for any assistance.
1.) to refine the 10 limitation of host within the network you couold install another device inside network that PAT - translation of Port addresses that hide all the IP addresses behind his foreign address.
All PC-> [device router/PAT] - [PIX Firewall] - [router]-> Internet
(2.) to buy/pbtain a license longer write a mail to:
mailto:[email protected] / * /
The product update:
PIX-501-SW-10-50 = software upgrade license for 501 10 to 50 users PIX = approximately 340$ US
PIX-501-SW-10-UL = software upgrade license for the 501 user 10-for-unlimited PIX = about 400$ US
3.) World normal political deadlock depends on your company security policy, someone should set one, many companys trust their employees and allow all outgoing traffic. Might be good to block traffic P2P, Multimedia Streaming stuff, but this is not possible with OS 6.3.4 Release. You must wait for PIX OS 7.0, which is not available for PIX 501.
