PPTP VPN pix 501 question

I'm relatively new to the security stuff.  I'm a guy of the voice.  I created a Pix 501 for IPSEC VPN and works very well.  Then I tried it setting up PPTP VPN.  I use Windows XP to connect.  It connects fine, but I can't ping to the inside interface on the PIX.  I can do this by using IPSEC.  Any ideas?   Here is my config:

:

6.3 (3) version PIX

interface ethernet0 car

interface ethernet1 100full

ethernet0 nameif outside security0

nameif ethernet1 inside the security100

activate the password * encrypted

passwd * encrypted

You will have to connect to an internal system inside and out run the PIX using pptp.

For ssh access the PIX, you will also need additional configuration, see the section on code PIX pre 7.x, section access ssh to the security apparatus .

    I'm sure it has something to do with NAT or an access list, but I can't understand it at all. I know it's a basic question, but I would really appreaciate help!
    Thank you very much
    Trevor

    "No. - nat' ACL doesn't seem correct, please make sure you want to remove the following text:

    do not allow any No. - nat icmp access list a whole

    No No. - nat ip 172.16.0.0 access list allow 255.255.0.0 any

    No No. - nat access list permit icmp any any echo response

    No No. - nat access list permit icmp any any source-quench

    No No. - nat access list permit all all unreachable icmp

    No No. - nat access list do not allow icmp all once exceed

    No No. - nat access list only allowed icmp no echo

    You must have 1 line as follows:

    access-list no. - nat ip 192.168.5.0 allow 255.255.255.0 172.16.0.0 255.255.0.0

    Please 'clear xlate' after the changes described above.

    In addition, if you have a personal firewall enabled on the host you are trying to connect from the Client VPN, please turn it off and try again. Personal firewall of Windows normally blocks the traffic of different subnets.

    Hope that helps.

  • Help with vpn pix 501

    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?

  • 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.

    (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.

  • PIX 501 question?

    Hello

    I have a PIX 501 and received 1 single public IP address from my ISP and I need to access a server on the private network of outside (Telnet or FTP).

    How to translate the Private IP of the server to the public ip address for the external interface of the firewall and specifying the port ftp or telnet only? is this possible?

    Thank you

    The pleasure is mine.

  • VPN pix 515 questions

    Hello

    We strive to provide access to the remote client to a server on the inside interface. We have read a lot of topics similare, but still does not work. Can someone please take a look at our configuration and let us know what we're doing wrong?

    Our int are as follows:

    outside = 204.222.162.0

    inside = 192.168.1.1 - 254

    DMZ = 204.222.161.0

    Thank you

    Hello

    You must have a static nat translation for the internal server.

    static (Inside, Outside) netmask 255.255.255.255 0 0

    Then create an access list to allow access to the host (public IP) with port...

    ex:

    out_to_in list access permit tcp any host 1.1.1.1 eq telnet

    Apply the ACL to the external interface.

  • VPN PPTP and PPPOE CLIENT ON PIX 501

    Hello

    Can I create a PPTP VPN and a client connection on a PIX 501 with a client to my ISP PPPOE connection. The PPPOE ip is dynamic and the VPN will be a static IP address. They gave me a username and password for VPN and PPPOE. Him also gave me an ip address for the VPN server.

  • 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.

  • 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.

  • A PIX 501 can connect to a VPN service?

    Can a PIX 501 6.3 (4) establish a VPN to a supplier like www.privateinternetaccess.com?  They claim to support PPTP and L2TP/IPSEC.  If so, how the PIX should be configured?

    Thank you.

    No, none of the networking gear (Inc. ASA) can be configured as PPTP and L2TP over IPSec client client.

    Both are PC or MAC software.

  • 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:

    http://www.Cisco.com/en/us/products/HW/vpndevc/ps2284/products_configuration_example09186a00800949d2.shtml#tshoot

    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
