• Customer Pix unit inside and dmz networks

  Are there problems that prohibit a client to the unit to start connections to hosts on pix dmz networks and pix inside at the same time?

  You can provide a link that describes the side PIX of the two networks not only inside network access configuration?

  Oops, yes sorry, brain fade from me, do not take into account my first email. Your configuration would look like this:

• 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

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

  I hope this helps!

• PIX, VPN, PAT and static

  I want to activate an incoming and outgoing VPN on a PIX configured with PAT. I enabled ESP and UDP/500 on the appropriate access to the lists, but must provide a static for inbound traffic. I already use a static for incoming SMTP traffic, and I don't see how to do the same thing for udp/500, but how do I ESP traffic?

  Any suggestions gratefully received.

  If you are referring to a static port, you can create one for ESP since static port can only be created for TCP/UDP and ESP is located just above the intellectual property, it is NOT a TCP/UDP protocol. You will need to create a one-to-one static for this internal VPN server and have your clients to connect to this address. This will chew global IP address to another one, sorry.

• A Site VPN PIX501 and CISCO router

  Hello Experts,

  I have an at home test lab, I set up a site to site vpn using a router Cisco PIX501 and CISCO2691, for configurations, I have just a few links on the internet, because my background on VPN configuration is not too good, for the configuration of routers, I followed this link:

• PIX DMZ outward

  I have an intranet with 3 PIX 515 6.3 Firewall, exterior, Interior and DMZ interface.

  I want to access DMZ w/o NAT inside and outside, but want NAT to inside.

  the addresses are

  domestic 192.168.10.XX

  DMZ 197.28.10.xx

  outdoor 197.28.8.XX

  Need help.

  Have Web, FTP, and DNS on DMZ servers that must be available for outside and inside.

  Can you ping the web and ftp servers of either inside or outside? How does the PIX itself? Otherwise, I look at the routing configuration (i.e. the default gateway) on each one and check that you have all the IP addresses configured doubles. Check also for any software firewall on servers.

  Looks like you're closer...

  I guess what I really wonder is if someone can convert the version of site to site of this VPN ASA 8.2 config so I can compare it to what I have. I need to have this, so I can just fall into place and work.

  Also, it does appear that political isakmp 40 are used, correct?

  On your ASA in Setup mode, simply type vpnsetup steps for remote access ipsec or vpnsetup site - not and it lists what it takes or you can download the PIX of the ASA migration tool.

• Cisco VPN Client and Windows XP VPN Client IPSec to ASA

  I configured ASA for IPSec VPN via Cisco VPN Client and XP VPN client communications. I can connect successfully with Cisco VPN Client, but I get an error when connecting with the XP client. Debugging said "misconfigured groups and transport/tunneling mode" I know, they use different methods of transport and tunneling, and I think that I have configured both. Take a look at the config.

  PS a funny thing - when I connect with client VPN in Windows Server 2003, I have no error. The only difference is that client XP is behind an ADSL router and client server is directly connected to the Internet on one of its public IP of interfaces. NAT in the case of XP can cause problems?

  Hello

  For the Cisco VPN client, you would need a tunnel-group name configured on the ASA with a pre-shared key.

  Please see configuration below:

  http://www.Cisco.com/en/us/products/ps6120/products_configuration_example09186a00805734ae.shtml

  or

  http://tinyurl.com/5t67hd

  Please see the section of tunnel-group config of the SAA.

  There is a tunnel-group called "rtptacvpn" and a pre-shared key associated with it. This group name is used by the VPN Client Group name.

  So, you would need a specific tunnel-group name configured with a pre-shared key and use it on the Cisco VPN Client.

  Secondly, because you are behind a router ADSL, I'm sure that's configured for NAT. can you please activate NAT - T on your ASA.

  "crypto isakmp nat-traversal.

  Thirdly, change the transformation of the value

  raccess 1 set transform-set vpnclienttrans crypto dyn1 dynamic-map

  Let me know the result.

  Thank you

• NAT VPN tunnel and still access Internet traffic

  Hello

  Thank you in advance for any help you can provide.

  I have a server with the IP 192.168.1.9 that needs to access a subnet remote from 192.168.50.0/24, through the Internet.  However, before the server can access the remote subnet, the server IP must be NAT'ed to 10.1.0.1 because the VPN gateway remote (which is not under my control) allows access to other customers who have the same subnet address that we do on our local network.

  We have a 2801 Cisco (running c2801-advsecurityk9 - mz.124 - 15.T9.bin) set up to make the NAT.  It is the only gateway on our network.

  I have configured the Cisco 2801 with the following statements of NAT and the relevant access lists:

  access-list 106 allow host ip 192.168.1.9 192.168.50.0 0.0.0.255

  NAT extended IP access list
  refuse the host ip 192.168.1.9 192.168.50.0 0.0.0.255
  deny ip 192.168.1.0 0.0.0.255 192.168.3.0 0.0.0.255
  ip permit 192.168.1.0 0.0.0.255 any

  route allowed ISP 10 map
  corresponds to the IP NAT

  IP nat EMDVPN 10.1.0.1 pool 10.1.0.1 netmask 255.255.255.0
  IP nat inside source list 106 pool EMDVPN
  IP nat inside source map route ISP interface FastEthernet0/1 overload

  When the server (192.168.1.9) attempts to ping on the subnet of 192.168.50.0/24 devices, the VPN tunnel is established successfully.  However, after that, the server is no longer able to access the Internet because the NAT translation for 192.168.1.9 has changed since the external IP address of the router (FastEthernet0/1) at 10.1.0.1.

  The documentation I've seen on the site of Cisco says that this type of Setup allows only host subnet communication.  Internet access is not possible.  However, maybe I missed something, or one of you experts can help me.  Is it possible to configure the NAT router traffic destined to the VPN tunnel and still access the Internet by using the dynamic NAT on FastEthernet0/1?

  Once again, thank you for any help you can give.

• VPN client and contradictory static NAT entries

  Hello, we have a VPN IPSEC implemented on a router for remote access. It works very well, for the most part. We have also a few PAT static entries to allow access to a web server, etc. from the outside. We deny NATting from the range of IP addresses for the range of VPN client and it works except for entries that also have PAT configurations.

  So, for example, we have web server 10.0.0.1 and a PAT redirection port 10.0.0.1: 80 to the IP WAN port 80. If a VPN client tries to connect to 10.0.0.1: 80, the syn - ack packet back to the customer WAN IP VPN on the router! If the VPN client connects to the RDP server 10.0.0.2:3389, it works very well that this server is not a static entry PAT.

  Is there a way to get around this?

  Thank you!

  There is a way to get around, use the same settings you have for your dynamic nat in your nat staitc entries, something like this:

  Currently, it should show as:

  IP nat inside source static XXXXX XXXX 80 80

  you need to take it

  IP nat inside source static 80 XXXX XXXX 80 map route AAAA

  When your itinerary map YYY refers to something with an acl that you refuse traffic from inside your router for the pool of vpn

  IP Access-list ext nonat

  deny ip 10.0.0.0 0.0.0.255

  Licensing ip 10.0.0.0 0.0.0.255 any

  route allowed AAAA 10 map

  match ip address sheep

  You even need all the static PAT

• Client VPN gets incorrect SPI size Pix

  Try to get a customer VPN connected with a pix515e. PIX is 6.3 (3) running. Customer is 4.0.4 we get same errors of dial-up, cable modems, etc.

  The connection drops just during the negotiation. We thought it might be something MTU, but have you tried each MTU under the Sun, and the error remains the same for all connections regardless of MTU.

  I have attached the config of the pix, the log of the VPN client and the pix debugging messages.

  Thanks for any help someone can provide...

  your proposal of IKE on the PIX is the following:

  part of pre authentication ISAKMP policy 20

  ISAKMP policy 20 aes-256 encryption

  ISAKMP policy 20 chopping sha

  20 5 ISAKMP policy group

  But this (http://www.cisco.com/univercd/cc/td/doc/product/vpn/client/rel4_0/admin_gd/vcach6.htm#1157757) shows that the VPN client does not support this proposal. Change your group to 2, and then try again. 5 Diffie-Hellman group is supported only when you use digital certificates, which you're not.

• The remote VPN Clients and Internet access

  I apologize in advance if this question has already been addressed. I am currently using a PIX Firewall Version 6.1 520 (2) running. I have several remote users that VPN for the PIX. Once the VPN tunnel is started, they are more able to connect to internet from their local computers. Is there a configuation on the PIX that allows remote users to have access to the internet when you are connected to the PIX.

  TIA,

  Jeff Gulick

  The Pix does not allow traffic enter and exit on the same interface. Therefore, a VPN user cannot access the Internet through the tunnel. If you use the Cisco client, enable tunneling split so that all traffic through the tunnel.

  If you use PPTP, you can turn off the option that makes the remote network, the default gateway. However, local routes should be added to these clients when they connect.

  Or you can use an additional interface on the firewall. One that puts an end to VPN tunnels and another providing for Internet connectivity. In this way the traffic is not enter/leave on the same interface.

  Of course, it is preferable if the customer Internet traffic does not go through the tunnel. It wastes your bandwidth and has security problems as well. I suggest you use the client to Cisco and the split tunneling.
