Several Interfaces of VPN - Pix 6.3 (5)

• 3 interfaces and routing PIX

  Hi all

  I have a PIX 515E configured with 3 interfaces, exterior, Interior and a Tunnel interface to my VPN clients. VPN clients not only access within the network, I have to move them to other networks through the external interface. As you cannot route the IPSEC packets from the same interface its entry, which is why I used a separate interface for VPN clients. Default gateway is set to the external interface. Now the problem is that when the vpn users try to connect to Internet, Tunnel interface is getting traffic but does not send back as default route traffic is defined on the external interface.

  Tunnel interface is 192.168.32.253 and if I connect from a pc with the ip address of 192.168.32.50, its works perfectly fine and also routing traffic to other networks through outside as PIX knows where to forward packets. Can someone please help me solve this problem of routing in PIX.

  the Interior is 192.168.33.254 security 0

  the outside is 192.168.34.254 security 100

  The tunnel is 192.168.32.253 security 90

  NAT (inside) - 0 110 access list

  access-list 110 permit ip 192.168.33.0 255.255.255.0 any

  Thanks in advance.

  Unless you know that networks, clients must connect to it may not be a solution, given that it looks like you need the default routes two, one for traffic encrypted clients and the other for traffic not encrypted Internet. You may be able to create a NAT pool in the router that provides Internet access to the Tunnel interface so that all incoming client traffic is coordinated in this router to an address from a pool. That would make all remote clients look like they came from a subnet, so you wouldn't need a default route on the interface of Tunnel in the PIX. You will probably need to do this router's Internet interface an interface 'ip nat inside' because I don't think that IOS supports dynamic NAT pools with 'ip nat outside source. It sounds backwards, but I think it would work. You'll probably also want to use an access list or with the pool route map, NAT to only apply to the traffic to the Tunnel from PIX interface (i.e. VPN traffic), as I'm assuming that the same router provides Internet connectivity for the interfaces from the outside and the Tunnel to the PIX.

  Good luck!

• 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:

• Public interface on VPN 3000

  Hello

  It is as sure to fix the public interface on a VPN 3000 Concentrator on the internet? Or should there be a firewall in front.

  I understand that the public interface is "hardcoded" and only open ports you'd pass firewall anyway, but I just wanted to check with experts to ensure that :-)

  Peter

  Hi Peter,.

  I don't think there are major problems involving the public interface of VPN 3030 Internet. It is means in reality for public access... it is a little hardened to allow only specific protocols... If you have an ID, you can monitor the traffic on this interface and shun unnecessary connections if necessary... you also have filters on the public interface, which allows you to restrict the traffic...

  set the vpn behind a firewall increases the complexity of your network. You may as well have this behind, but it will be a little complicated.

  I hope this helps... all the best

• Interface GUI language PIX

  Guys,

  Is the graphic interface of the PIX with a multilingual browser configuration? What languages are supported? In particular is a Japanese GUI available? And if cannot, therefore, a user/administrator choose which language he wants when connecting?

  Hi Vito,

  I've never heard of PDM to be multilingual.

• Redirect pat interface on a PIX PPTP

  Is it possible to redirect traffic PPTP from the external interface of a PIX, which has a unique IP address or are you really to have an any translated IP peripheral PPTP termination.

  Example, I have a PIX with a unique public IP I have to redirect ports 23 25 53 110 to an in-house 2 k server. I would be able to redirect traffic to this server pptp also or will I have problems with the gre and need a new ip address?

  Patrick Laidlaw

  GRE will cause you problems. PPTP uses GRE (Protocol IP 47) at the time and TCP 1723 port. You will be able to redirect TCP/1723, but not the GRE traffic.

  To do this, you will need a separate IP address.

• PIX & lt; -> user policies VPN PIX and the Windows domain controller

  I've set up a star using IPsec VPN PIX network, all IP traffic is allowed to pass through.

  At the Center, there is a Windows 2003 Small Business Server.

  On remote sites, there is only Windows XP clients used by employees working remotely in the central office.

  Initially, I had a problem of authentication on the server, but I found a document suggesting the Kerberos setting to go to TCP instead of UDP and it solved this issue.

  Now, there is one problem remaining, I can authenticate and access the server resources such as file shares, I can connect to the server Exchange etc. But the client computers do not receive from the server group policies. The error message I am getting in Event Viewer Windows is Userenv id: 1054 - Microsoft suggestion is to check if the DNS works and works DNS, I can locate the DC etc. without problem.

  I tried to make LDAP queries on the server, and again, it works without problem.

  The NetBIOS resolution works very well.

  Basically, everything seems to work expect to get group strategies.

  Does anyone have any suggestions where I should look planned for the solution to this problem?

  Kind regards

• Ping inside the interface on a Pix 501 from outside the network

  All the

  I have a Pix 501 firewall at a remote site with an IPSEC tunnel established at HQ. We have an analysis tool which remote sites for us let proactively pings know when a site crashes. I want to set up this ping the inside interface of the Pix tool as I can with 871 routers; However I can't configure the Pix to allow ICMP inside interface. I know by default that the Pix does not allow ICMP to the opposite interface and I was wondering if someone could help me with a configuration that will allow this? I enclose my configuration of the pix!

  Hello

  By raising the ordering tool, it seems that the 'management-access' command was introduced in version 6.3

• A VPN client can go same interface on the Pix 515

  A user in a Pix VPN and get an address x.x.x.x via an ippool on the Pix. Once this is done, they will need access to information on the public network. Is it possible since they come out of the same interface?

  I can open ports and route subnets on our core routers, but that doesn't seem to work.

  Thank you

  Dwane

  Hi elodie

  You can do this by entering the following command

  permit same-security-traffic intra-interface

• PIX 515 with several interfaces see each other

  Hello

  I realize that this question has been asked in different ways, but I have yet to see my way. My problem is we have a pix515e with 6 interfaces, all interfaces can go out to the outside world very well, but they can not cross to the other. We do not have any router behind them, we 10.0.0.1 and 10.0.1.1, etc. as interface id how to see the other side of the other I need 2 interface see interface servers and even inside. Also how can I get ip addresses translate. for example we have a mail server on the inside interface with 10.0.0.60 translated in X.X.X.60 on the external interface if the outside world can see. Computers of the interface 2 see this machine as X.X.X.X.60 not the fact that it is on the interface right next to her, and therefore can not find. Inside machines translated at 10.0.0.60 address please help. and I hope that this can be done without routers behind the pix.

• NAT Traversal on site to site VPN pix

  I don't think it's possible to implement NAT traversal between a site to IPSEC VPN using ESP tunnels?

  Our ISP to the remote end will provide only a public IP address and which is attributed to their router...

  Sites are using pre-shared keys and IKE

  for example...

  LAN-PIX1-ISPROUTER-INTERNET-ISPPATROUTER-PIX2-LAN

  I have attached the card encryption for more info

  Thanks in advance...

  I guess that NAT - T is most commonly used in a customer VPN environment, but I'm sure that its not limited to this type of connection.

  I just set up a VPN this morning with the help of a customer on a router running 12.2.15T and tested connection with NAT - T works very well by using IP addresses.

  NAT - T enabled by a NAT detection process, and there is that to protect the ESP of a change should work in both environments.

  I'll have a go in my lab, see if I can implement and check it.

  However by going to the original post, you say that only one address is available from the ISP, it is on the router for pix link?

  Where are the limits of NAT, I expect to be in the PIX, but it must be a public IP address on you interfaces also. You can then use the external address as endpoints IPSec, don't need NAT - T in any case.

• SonicWall VPN PIX - does not, could someone help?

  Hi all

  I'm trying to set up an a 506th PIX VPN tunnel (firmware 6.3 (2)), a firewall SonicWall Pro. It does not at the moment. Phase 1 is ok but the phase 2 is not, the VPN tunnel has not been established, and the security association is removed after a minute or two. I enclose below the PIX config and an attempt to create VPN tunnel debugging output (slightly modified and cut for reasons of confidentiality). The PIX already has other two VPN configured which work perfectly.

  I would be very grateful to anyone who could help me answer the following questions about this VPN configuration:

  1. to debug output, which means the next?

  ISAKMP (0): retransmission of the phase 2 (0/0)... mess_id 0xafc08a94

  crypto_isakmp_process_block:src:remotevpnpeer, dest:vpnpix1 - dpt:500 e0 spt:500

  ISAKMP: error msg not encrypted

  2. in the config, I don't know if the 3 static controls are necessary and how it might interact... What do you think?

  3. in what order things happen in the PIX when traffic is from the local network to remote network by VPN? What is NAT then treatment then setting up VPN to access list? or or treatment, then NAT and VPN to access list? or another possibility?

  4. How can I get it work?

  Thank you very much in advance for any help provided,

  This, however, should not stop the tunnel of Phase 2 of the course of construction, they would stop flowing above the tunnel, traffic, so you still have a problem somewhere. What I'm guessing, is that the Sonicwall (SW) has a different encryption-defined list access, it must be the EXACT OPPOSITE of what is configured on the PIX. In other words, the SW should be encrypting the traffic of "remotevpnLAN-24" "intranet/8", make sure that the subnet mask ar ETHE same too. "

  To answer your questions:

  1. it simply means that the PIX has not received a response and is to retransmit the last ISAKMP packet. The process_block simply means that the PIX has dropped a package that was to be encrypted because the IPSec tunnel has not been built. If you get the tunnel built, these messages will disappear.

  2. the 3 first static does not appear to be linked to the tunnel IPSec, if they are simply to access a server inside, then they will not affect this VPN tunnel. The last of them should be deleted, as I already said.

  3. for traffic initiated from inside the PIX, the order is incoming ACL, then NAT, IPSec processing. That's why your OUTGOING ACL must allow traffic first, then your NAT 0 statement refuses to be NAT had, then the encryption function is the traffic and the number.

  4 do what I said above :-)

  If you still have no luck, re - run debugs, but initiate traffic behind the Sonicwall, in this way the Sonicwall will try and debug of build that the tunnel and you will get more information on the PIX. Mainly, we'll see what traffic model the SonicWall is configured to encrypt (you don't see if the PIX initiates the tunnel).

• Allows you to control access VPN PIX

  I have a situation. I want to use Cisco PIX to create 2 VPN tunnels: called "admingroup"(subnet 192.168.10.X) for full access and another called "vendorgroup"(subnet 192.168.11.X) for limited access (only www access to 192.168.1.100). "" "" Admin and the seller will use Cisco for XP vpn clients. But for some reason, the admin and vendor access even. I think I may need to remove the command "sysopt", currently I use admingroup to PIX of remote connection,

  1. can I remove "sysopt" remote control while I vpn in PIX?

  2. why the admin and the seller have equal access?

  Here are the PIX config in a short version:

• Problems with VPN PIX 525 Lan-to-Lan Cisco 2610XM

  Hello world

  I have a VPN with PIX 525 versi problems? n 7.2 (1) and Cisco 2610XM Version 12.3 (18). When start the PIX, all tunnels works well, but 6-7 days, some of the tunnels do not work properly. Traffic passes the tunnel with some networks, but not with all networks. Sometimes the tunnel descends and it is imposible to go upward.

  Attach them files are the "debug crypto isakmp" in both devices.

  Thank you and sorry for my bad English

  If your configuration of the tunnel on router 7500 series, the tunnel interface are not supported for politicians to service in the tunnel interfaces on 7500

• 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:

  --------------------------------------------------------------------------

  Thank you!

  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.
