• Vpn client access to the DMZ host

  I'm having a problem where my customers who establish a VPN with Pix 515 cannot access hosts on the DMZ. VPN clients can access hosts inside network without any problems. I discovered that when I make a route to trace from a client computer that has established a VPN connection to a host on the DMZ, he tries to go through the default gateway of computers instead of the client from cisco. Any ideas?

  More information:

  When a client connects with the PIX over the VPN, it is given the internal DNS servers and the DNS Server internal, we have a host entry that says "www.whatever.com" 2.2.2.2 (this is the DMZ host). Customers within the network can access this host with problems, it's just the customers who establish a VPN connection. But the VPN Clients can access "www.whatever.com" using the public ip address. The problem is that if remove us the entry from the host on the DNS server so that the name of "www.whatever.com" decides the public ip address customers inside will not be able to access the DMZ host. The names and IP numbers are not real just using those as an example.

  Any help would be apperciated. Thank you

  You'll currently have something like this in your config file:

  sheep allowed ip access-list

  NAT (inside) 0 access-list sheep

  This tells the PIX not to NAT any traffic from inside interface, which is to go to a VPN client. You need the same thing but for the DMZ interface, then add the following:

  sheep allowed ip access-list

  NAT 0 access-list sheep (dmz)

• to access computers on adhoc network__

  How do I enter two vista computers on an ad hoc WEP network?

  Hello Gavin986,

  ·         You configure the Ad - hoc network on both computers for the first time?

  If you try to connect to computers that already host Ad - hoc network, here's what you need to do:

  1) go to start and click on connect to.

  Connect 2) to a network window appears. This window displays all the available connections, which are remote access, VPN and wireless connections, but your emphasis is on an ad-hoc wireless connection. Scroll through the list and select the ad hoc wireless network and click Connect.

  Note: Also try to temporarily disable encryptions (WEP) and then try to sign in if you are not able to connect. You can enable encryption on host computers after you connect computers with success...

  (3) once you are connected, you will see the message to save the network. You can then check on save this network and close the window.

  If you have not set the Ad - hoc network on the host computers, here's what you need to do:

  1 open the connect to a network by clicking the Start button, then click on connect to.

  2. click on set up a connection or network.

  3. click on set up a network of ad-hoc (computer to computer), click Next, and then follow the steps in the wizard.

  You can refer the articles below which will give you more information on this:

  Also, note that the Ad hoc networks are created temporarily, once you disconnect from the computer.

• Is access to the DMZ on VPN best practices?

  Hello

  We have aDMZ which hosts comments wireless society and also installed on the same network of network security cameras. We must be able to access these security cameras remotely (from office) and one way to do that would be to include a network DMZ on your remote access VPN access. I don't know if this is a good/best practices since the same DMZ network also called Wireless on it.

  I think that since the security/DVR cameras is something private, they should be moved inside the network instead of on the DMZ.

  Could you please comment and suggest?

  Thank you.

  Yes! Move the inside security cameras and create another guest lan, do not use the demilitarized zone for the guests!

  DMZ must expose several services outside.

• My wired network cannot access computers connected wirelessly

  Very strange problem of networking:

  Everything is Windows 7 and the network is defined as a working network.

  My laptop (wireless) can see and access my desktop (wired), but my desktop computer, although it can see my laptop, cannot access.
  If I connect the laptop cable, the Office can then access. I do not change anything, just plug in the cable.

  If also connected to my netbook with unusual results. The netbook runs Windows 7 starter and is wireless
  He can see the desktop and the laptop and access, but does not appear in its own computer network list in the Explorer.
  It is visible in the desktop browser, but are not accessible from it. It does not appear on the Explorer of the laptop at all.
  If I have the cables up to the netbook, the Office can then access it, but the netbook can then access the laptop if it is wireless.

  Just to clarify - netbook on wireless - I can access the laptop (wireless or wired)
  NetBook on cable (wireless or disable as well) I can still see the laptop, but cannot access it.

  When I first put this network - a couple of years - all spoken at all. I think I lost it after an upgrade of windows, but don't know when because I rarely access the laptop from the desktop, usually the opposite.
  Anyone got clues? Or how can I delete all networks and start again because I have a different network (same working group) on each PC name, but I can't change the names - windows seems to decide what to call them.

  Hello

  Thanks for the reply.

  I would appreciate if you can help me with the following information.

  1. what happens when you try to access wireless computers? You receive an error message/code?

  2. don't you try to access folders to disable firewall/antivirus?

• Access to the DMZ to remote sites via VPN S2S

  We have an ASA 5520 and two remote site ASA 5505 that connect to each other through tunnels VPN S2S. They are doing tunneling split, while local traffic passes over the tunnel. We are local LAN (10.0.0.0/16) and our network to the DMZ (10.3.0.0/24) on the main site. The DMZ hosts our external sharepoint, but we access it internally

  The problem is site A (10.1.0.0/24) and B (10.2.0.0/24) have no idea of it, and when you try to go to the site, it fails. You can access it via the external site address, but that's the only way. Normally the external address is blocked when you're an intern.

  That I'm stuck on is even when we had all sent traffic from Site A to our Senior Center, would find it yet. I do a separate vpn purely tunnel that traffic to DMZ?

  Yes. So if you do this in ASDM under Edit Site profile connection Site, it will look like this.

  Local network: 10.0.0/16, 10.3.0.0/24

  Distance: 10.1.0.0/24

• Cannot access computers running Windows XP Pro on wireless network.

  3 machines on the wireless network. 1 running Windows 7; 2 running Windows XP Pro.  Previously, I had full access in all directions. No problems.   Now I can't access Pro X machines. Neither the machine, Windows 7, or a XP Pro on the other machine. I can see XP machines in Windows Explorer with the complete display of all shared folders, but when I try to access a file, I get an error message. "\\Tiger\Documents and setting are not available. You might not have permission to use this network resource. Contact the administrator of this server to find the you have permissions to access. Not enough server storage is available to process this command. "(This is the message I get when I try to access one of the XP machines on the Windows 7 machine The message on a XP machine when I try to access the other XP is the same, except that the last sentence is "the network path is not found."  I CAN have full access to the Windows 7 machine is XP Pro machines. I checked the properties of sharing on both XP machines, and they seem to be the same when everything worked correctly. I have installed any new program - except the regular updates of Windows and the frequent update of the antivirus of Trend Micro. Any solution?

  Thanks Steven Winograd. I don't know how to frame a search that would have led me to the Article 177078, or that it applies to my problem, once I found it. I may have a new technique, but I CAN follow a recipe from Cookbook to change the IRPStackSize. Increase the value of 15 to 18 solves the problem without a further hiccup. Thanks again.

• Cannot access the Web server in the DMZ from the inside using IP global

  Hi all

  I hope it's a very simple question.

  I'm running a PIX 515 firewall v6.3. I set up a Web server in my DMZ and use static NAT for re-branded it overall static IP address. Access from the outside of the demilitarized zone works remarkably well. I can access inside the interface Web site using the internal IP, but I can't access it from inside interface using the global IP are entrusted to him.

  Is there a particular reason why this would not be allowed? My feeling was that the request would be forwarded via the external interface (as it is a global IP address) and then be bounced back by my sense of the ISP the request would come to the new external interface (as the static NAT is applied to the external interface).

  However if I try and access the global IP from my inside interface, then the browser can not find the server.

  can someone explain why this is so? Any information would be appreciated.

  see you soon,

  Wayne

  Code v6 pix or less don't let you have traffic "back" or return flow via the same interface on which it was sent. Having also your bounce back off of an external server traffic is never a good idea, because you won't be able to distinguish which and rogue attacks by spoofing someone outside your network.

  Since you are using pix 6.3 code, you may be able to outside the NAT. Add this static to your config:

  static (dmz, upside down) 203.169.113.110 10.1.1.27 netmask 255.255.255.255 0 0

  You may need to run a clear xlate after adding the new static statement. Note that the interfaces: it's demilitarized zone, inside inside, dmz.

  I would like to know if it works.

• To access the servers in the DMZ

  People:

  I have a PIX 515E and I need to access a SQL Server that is inside the network... I don't know if I should activate NAT on the demilitarized zone to be able to 'see' the servers inside...

  I tried a

  > static (dmz, inside) 192.168.2.0 192.168.2.0 netmask 255.255.255.0

  to activate servers on the DMZ for access within the network without translation... but I can't create a static to a low security to a high security interface...

  I wonder if anyone has the same configuration problem?

  should I try to activate NAT on the DMZ also?

  It's my current setup!

  Thank you very much!

  Did you apply an access list to allow traffic from the dmz to the inside interface?

  Also, try to be specific with the server you are trying to provide access to the.

  static (inside, dmz) xx.xx.xx.xx xx.xx.xx.xx 255.255.255.255 netmask (where two groups of xx.xx.xx.xx represent your address of sql server)

  Then add the following list of access

  access-list 101 permit tcp any host xx.xx.xx.xx eq sql (again, xx.xx.xx.xx is sql server)

  Access-group 101 in the dmz interface

  (test you can do initially access list permit all traffic instead of just sql, then tighten it to the top when you are sure that the static command works)

  Hope that helps. Allowing less than an interface on a security interface traffic higher security is carried out with controls static and ACL (or ducts), so you seem to be on the right track.

• Several statement list Access NAT (DMZ) 0

  Hello

  IM I have problems with remote VPN. The scenario is as follows:

  I have I have few clients who will connect remotely via VPN. Until today, one of them needed to enter my DMZ. But now I want a different profile (the cause is a new client) to access one of my server in the DMZ.

  So I said all of the VPN, the ACL settings, but when I want to declare the nat 2 access-list newclient (dmz) it does not work. But if I declare the nat 0 access-list newclient (dmz), it works, BUT it removes the previous 0 having my other client nat. Is there a way to create several access list statement 0 - nat (dmz)?. If this is not the case, how could I solve this problem?

  André,

  You can have as a NAT exempt list of access by interface (nat rule 0).  I understand what you are trying to accomplish.  You use the vpnashi and vpnlati access list to control access to devices for different customers through VPN group policies.

  What I do is the following:

  Create an ACL for the VPN client (that you have, with vpnashi and vpnlati)
  Create an ACL for NAT exemption for the interface (inside sheep, sheep-dmz, etc.).

  Create the ACEs within the exempt ACL of NAT that corresponds to your VPN client access-list.

  It is allowed to have multiple statements within a NAT exempt list to access.  This will not have a client VPN access to things, it shouldn't.

  For example:

  access-list sheep-dmz allowed extended host ip 192.168.16.28 192.168.125.0 255.255.255.0

  192.168.125.0 IP Access-list extended dmz sheep 255.255.255.0 allow host 192.168.16.28

  NAT 0 access-list sheep-dmz (dmz)

• VPN access to DMZ host

  I went through the forum messages to allow VPN access to a DMZ host but miss me something and hoping another set of new look will see the question.  Basically, need a VPN profile to allow the service provider to a host in the demilitarized zone.  VPN connects but I can't access the host. Here is the config and Yes its an old Pix 515 running version 7.2 (5) - will get new firewall soon.

  Thank you

  Gary

• PIX no DMZ access to

  I'll set up a DMZ on a PIX 515e and everything seems to work fine except that I can't get internet access from the DMZ servers. The only way I CAN get access is if I add a "permit ip any any" to the dmz access list. I only allow statements in the demilitarized zone access list and not to deny statements. The demilitarized zone should not allow all traffic flows due to its level of security?

  ethernet0 nameif outside security0

  nameif ethernet1 inside the security100

  nameif dmz security50 ethernet2

  I will attach a sanatized my PIX config. I hope it's a simple mistake that I'm missing.

  Thank you

  CB

  Exactly! You need to think about how the traffic goes through the pix - a ACL on a given int impact on all traffic through this int, regardless of the destination. So an inside interface ACL can impact traffic that passes through the DMZ and interfaces external, that this traffic passes through it. A DMZ interface acl will also affect traffic through it inside or outside (or all other interfaces)

• DMZ out OK; inside problems

  I have a Web server on a demilitarized zone which I want to access the inside network.

  Currently, I can access Internet from the DMZ Web server, the Web server of the Internet and the Web server would form inside.

  Access one another inside the machine while ssh would be in the Web server is that I can't do.

  This Web server will snapped a FTP mirror on the inside so I need this access.

  I've searched the forums and found several relevant examples, but the solutions have not worked for me.

  The example that I found was:

  +++

  "For the mail server (or any host on the DMZ) to access the inside to do the following:

  static (inside, dmz) 128.100.0.0 128.100.0.0 255.255.0.0 subnet mask

  fromDMZ list of allowed access host ip 192.168.0.2 128.100.0.0 255.255.0.0

  Access-group fromDMZ in dmz interface

  and for the zone demilitarized for access from the outside to do:

  "NAT (dmz) 1 192.168.0.0 255.255.255.0.

  +++

  If I activate the access on the DMZ interface group, I lose outside connectivity...?

  I currently have no liaison group on this CASE.

  Here are my relevant configuration lines:

  access-list 100 permit tcp any host 206.xxx.xxx.xxx eq www

  access-list 100 permit tcp any host 206.xxx.xxx.xxx eq ssh

  access-list 100 permit tcp any host 206.xxx.xxx.xxx eq ftp

  When I try to access machine and inside the demilitarized zone, I get the following error on the server logs:

  Incoming TCP connection deny from 10.xxx.xxx.xxx/1152 to 192.168.xxx.xxx/22 SYN flags on DMZ interface.

  static (DMZ, external) 206.xxx.xxx.xxx piggy netmask 255.255.255.255 0 0

  static (inside, DMZ) piggy Notes netmask 255.255.255.255 0 0

  FDPNATICK-2 FDPNATICK-2 static (inside, DMZ) mask of 255.255.0.0 subnet 0 0

  206 ~ is the range outside.

  192.168 ~ inside

  10 ~ is DMZ

  "piggy" is the DMZ server.

  'Notes' are I want to connect to the FTP server.

  TIA

  I think that the solution you found on the net was the right. You have lost connectivity to the outside because the access group you have applied has an invisible specific ip deny everything at the bottom of this one. As soon as you have applied it, it allowed your DMZ inside because you put it in the acl, but you did not reference for your dmz be allowed outside, what is needed now that you have a list of access applied to your dmz interface. Your static and Nat seems good, just make the changes to your dmz acl to allow the incoming connection and the connection outdoors. Take note of this source for your ACLs on dmz will be your dmz hosts and destination will be on the outside.

• ASA 5510 - VPN for DMZ with static rule?

  I have a 5510 ASA with a number of virtual private networks to other sites, allowing the traffic to and from the Interior of the networks.

  I need to establish a VPN rule to another site, but they have very little access to resources on my local network.  Because I am not in control of the SAA on this end permanently, I need to control that access on my 5510.

  (the following is not my real IP, but I use them for this example)

  My network: 10.100.1.x

  My DMZ: 192.168.1.x

  Internal network of other sites: 172.16.1.x

  I wanted to try to create a VPN between the site and the specific address of DMZ on my side and then allow access to internal addresses using static rules.  I decided to use a static rule to enable http access to a specific server (for example):

  static (inside, dmz) 192.168.1.200 tcp 80 10.100.1.200 80

  I need allow traffic here:

  access-list permits DMZ_IN tcp host 172.16.1.10 host 192.168.1.200 eq 80

  Access-group interface dmz DMZ_IN

  And of course, rules of access list which allow traffic that I can apply to the VPN:

  toSite host 192.168.1.200 ip access list permit 172.16.1.10

  And I don't want that traffic THAT NAT had between my DMZ and the other site:

  nonatDMZ of the host 192.168.1.200 ip access list permit 172.16.1.10

  NAT (dmz) 0-list of access nonatDMZ

  NAT (dmz) 1 0.0.0.0 0.0.0.0

  And, of course, the corresponding rules on their ASA must be in place, allowing traffic to 192.168.1.200, not NAT it.

  Everything is in place, but 172.16.1.10 to 192.168.1.200 http traffic never reaches 10.100.1.200.  I know the following:

  1. the VPN is configured correctly.  If I add rules allowing traffic to (and from) 172.16.1.10 and 10.100.1.200 directly, they work.

  2 packet trace shows me that traffic is allowed.

  3. the works of static rule: to access the 192.168.1.200:80 of another host on the same interface, DMZ, which brings me to 10.100.1.200:80

  4. in the process of running a sniffer package on 10.100.1.200 shows 172.16.1.10 traffic does not reach it.

  So I'm banging my head against the wall here.  I'm sure it's something simple I'm missing.  Anything else I need to check?  Should I go about this a different way?

  Thank you.

  What you are trying to reach is not supported. You cannot configure NATing between the inside and the demilitarized zone interfaces while your VPN connection is from the external interface. The static NAT (inside the dmz) that you have configured will only work if the connection is initiated from the inside towards the demilitarized zone and vice versa.

  I think that what you are trying to reach is only allowing access on TCP/80 to10.100.1.200 for the VPN tunnel.

  You must configure your option 1:

  1. the VPN is configured correctly.  If I add rules allowing traffic to (and from) 172.16.1.10 and 10.100.1.200 directly, they work.

  You can configure vpn-filter to limit the traffic to the only TCP/80, and he attributed to group policy that you have assigned to this particular tunnel group then.

  Example:

  web access list - allow permit tcp host 172.16.1.10 host 10.100.1.200 eq 80

  internal group-policy-strategy web

  attribute group web-strategy strategy

  value of VPN-filter web - allows

  global-tunnel-group attributes

  Group Policy - by default-web-policy

  Here is an example configuration for your reference:

  Hope that helps.
