PIX 501 - VPN - based
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.

Customer Cisco PIX 501 VPN connects but no connection to the local network
Hi all:
I am able to make a VPN connection to a PIX 501. The remote client is assigned an IP (192.168.2.1) also, but not able to access all the machines in the local network connected to the PIX.
I have attached the PIX configuration.
Advice will be greatly appreciated.

I can ping the remote client, on an inside ip behind the same pix
When I get the 'route add failure' above, but I cannot ping the computer name.
I activated traversal of NAT using the PDM, but when I connect with this option, I get the error that the "remote endpoint is NOT behind a NAT device this end is behind a NAT device" and ping fails.
Behind the pix are a few computers with no central server, so I'm failed a WINS server for remote clients.
I created the vpn with the wizard.
The configuration file is attached.
Any suggestion would be appreciated.
Kind regards
Hugh
Hugh, sure you can classify based on the whole conversation, but you don't have to do but be certainly provide assessments.
To sum up the shrinking global problems, the main objective was to ensure configuration VPN RA on the PIX501 has been corrected.
1. we have enabled NAT - T on the firewall - even if it wasn't the question, but need it either it should you RA other places - travseral NAT VPN sensitizes the firewall on the other ends NAT devices - here is some good information on NAT - T for reference in the future
http://www.Microsoft.com/technet/community/columns/cableguy/cg0802.mspx
2. we fixed the VPN-POOL/28 network as well as the access list and acl to be coherent crypto sheep.
Here is a link for future reference with many PIX configuration scenarios
http://www.Cisco.com/en/us/products/HW/vpndevc/ps2030/prod_configuration_examples_list.html
Finally, your only question remaining, we can say is purely isolated with the customer software vpn and MAC machine.
You could maybe try a different version of the client in the MAC, or also look at the release notes for the open caveats to avoid cisco cleint managing versions and MAC versions if there are problems.

Hi, I just got my PIX configured based on the clear capability statement, I got one of you this morning. Now, I'm trying to set up the VPN, I looked at the Cisco site (http://cisco.com/en/US/products/hw/vpndevc/ps2030/prod_configuration_examples_list.html#anchor14) but could not understand that we need to follow. Could you please send me the instruction or the link to configure vpn? Also, I don't have the vpn client to test my vpn, how what to do? As you can understand my question, I am new to cisco gear... Thank you.
Hello
I'm guessing that you need one of these two virtual private networks.
-Remote access VPN: where remote allows the Cisco VPN client users to access the resources of the company
-Site to site VPN: where two systems with IPSEC support establish a VPN tunnel, allowing the internal LAN from different termination points (offices) communicate.
You can find these two examples on the url you gave.
If the remote access, I'd watch
http://Cisco.com/en/us/products/ps6120/products_configuration_example09186a0080702992.shtml
And then also look at how to set up the split tunneling, then the home user can access the resources of the business AND Internet.
For the site to site VPN, it depends if your device is a PIX / ASA or a router.
It will be useful,

PIX 501 &; VPN Client unable to ping or encrypt traffic?
I'm new and I work on my CCNA. I have a Setup pix behind a dsl with NAT router that I can not turn off. I create a pin hole for IPSec traffic to port 500 to my pix off if. I can connect correctly the Client VPN software. I think I establish an IKE and IPSec tunnel very well. I used the wizard to configure the VPN. I have a pool dhcp which issues an IP address correctly, and user group with set password. There is no site-to-site VPN, the network is a network of peers without any DNS or WINS server on the local network. I'm lost, frustrated and tired of 45 minutes of driving on this site whenever I want to try to set up a new configuration. It is essentially a off the pix of the box. There not here all configurations at all really. Here is my config.

PAT on IPSEC VPN (Pix 501)
Hello
I work to connect a PIX 501 VPN for a 3rd party hub 3015. The hub requires all traffic to come from a single source IP address. This IP address is assigned to me as z.z.z.z. I have successfully built the VPN and tested by mapping staticly internal IP with the IP address assigned, but cannot get the orders right to do with PAT in order to have more than one computer on the subnet 10.x.x.0. This Pix is also a backup for internet routing and NAT work currently as well for this.
I can redirect traffic to my subnet to the remote subnet via the VPN, but I can't seem to get the right stuff PAT to the VPN using the assigned IP address. If anyone can give me some advice that would be great.
lines of current config interesting configuration with static mapping:

Dave,
(1) get rid of static electricity. Use more Global/NAT. The static method will create a permanent
translation for your guests inside and they will always be this way natted. Use
NAT of politics, on the contrary, as shown here:
not static (inside, outside) z.z.z.z 10.x.x.50 netmask 255.255.255.255 0 0
Global (outside) 2 z.z.z.z netmask 255.255.255.255
(Inside) NAT 2-list of access 101
(2) the statement, "nat (inside) access 0 2' list will prevent nat of your valuable traffic."
Delete this because you need to nat 2 nat/global card. (as a general rule, simply you
If you terminate VPN clients on your device and do not want inside the traffic which
is intended for the vpn clients to be natted on the external interface).
(3) with the instructions of Global/nat 2, all traffic destined for the remote network will be first
translated into z.z.z.z. Then your card crypto using the ACL 103 will encrypt all traffic which
sources of z.z.z.z for y.y.y.0 24. This translation wil happen only when traffic is destined for the vpn.
I hope this helps. I have this work on many tunnels as you describe.

I'm setting up a cisco pix 501 vpn tunnel but will have questions. The Firewall works although I am able to get out of the internet, but the VPN does not work. On the primary side, I see that the tunnel is up and the traffic is sent but not received.
Currently I'm sitting at the secondary location but don't know what the problem maybe. Anyone know what I have wrong which could prevent the data to send from this device?

Help!
I'm trying to set up VPN on my PIX 501. I have no experience of the PIX and have no idea where to start!
Any help will be greatly appreciated.
Thank you

Cisco 3640 to the PIX 501 site 2 site VPN performance specifications.
I intend on creating a site-2-site VPN in Star configuration with a Cisco 3640 as the hub and PIX 501 at the remote sites. My question is around the plug that I read.
.
The specifications for a PIX-501-BUN-K9 tell PIX 501 3DES Bundle (chassis, SW, 10 users, 3DES).
.
A question is what really "10 users. Which is the limit of the number of concurrent sessions, I have on the VPN at a given time, or that it means something else?
.
I also read the specs say that the Maximum number of VPN tunnels that can support a PIX 501 is 5. Because I'm not going to make a tunnel between the PIX 501 at the remote site and the 3640 on the central site, I think I would be OK. Is that correct or is the max value talk the maximum number of concurrent sessions on the tunnel tunnels?
.
Thank you.
UDP traffic always creates a session in the PIX so that the return traffic will be allowed in. The UDP timeout is 2 minutes but IIRC. If you go around NAT with a statement of "nat 0" should not create an xlate I think.
The real time is hard to say really, probably around 2 minutes for a UDP-only user, you would probably make a few 'local sho' orders on the PIX to really see for sure however.

L2l IPSec VPN 3000 and PIX 501
Hello
I have a remote site that has a broadband internet connection and uses a PIX 501. We wanted to connect them with our main office using our VPN 3000 via VPN site-to-site.
I followed the following documentation:
However the L2L session does not appear on the hub when I check the active sessions.
The network diagram, as well as the PIX config and the screenshots of the VPN configuration for the IPSec-L2L tunnel is attached.
Any help or advice are appreciated.
I just noticed that the PIX firewall, the phase 1 paramateres are not configured. You must configure the same PASE 1 and phase 2 settings on both ends of the tunnel.
For example, on CVPN 3000, you have configured settings Phase 1 as 3DES, pre-shared key etc... We have the same configuration on the PIX firewall too.
Here is an example of sample config
I hope this helps!

PIX 501 for Cisco 3640 VPN router
-Start ciscomoderator note - the following message has been changed to remove potentially sensitive information. Please refrain from publishing confidential information about the site to reduce the risk to the security of your network. -end of the note ciscomoderator-
Have a 501 PIX and Cisco 3640 router. The 3640 is configured for dynamic map for VPN. The PIX 501 is set to pointing to the 3640 router static map. I can establish a tunnel linking the PIX to the router and telnet to a machine AIX on the inside network to the router. When I try to print on the network of the PIX 501 inside it fails.

Hello
I have Microsoft CA server with the latest support CEP and pix 501 that gets the digital certificate. I also have the client certificate of Cisco, but VPN doesn't work
In the IPSec Log Viewer, I constantly "CM_IKE_ESTABLISH_FAIL."
It worked well prior to Win2k server has been completely updated with the latest patches.
The pix configuration is identical to that of article http://www.cisco.com/warp/public/471/configipsecsmart.html
I reinstall the stand-alone CA and support CEP server but not had any luck.
What could be wrong?
It looks like IKE implementation problem. Make DH group 2 policy ISAKMP.

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.
