• Configuration of the DMZ at R1213

  Hello

  I put implement R12 Configuration in a DMZ. We already have an existing instance of R12. Following Doc ID 380490.1 to implement the same, have chosen to proceed with option 2.4 that is to say, "with the help of Reverse Proxies only in the DMZ.

  I also talk about Doc ID 726953.1 that is specific to above the application method. Finishing with the configuration.

  My confusion is, how to start?

  Will I first clone web layer first, and then run adclonectx.pl?

  what I need to clone level apps.

  Help, please.

  Hello

  In this scenario, there is no cloning of any level.

  You just create a new directory in the $INST_TOP on the server exist for the web virtually outer layer.

• Configuration of the DMZ for MS access

  I set up a DMZ for a Web server. I'll probably put an RODC in there later, but for now I want to open ports to the domain controller.

  I'm a bit new to DMZ and I'm a bit confused.

  I put in place services for different ports and then configure the rules of lan/dmz coming out of the demilitarized zone to the domain controller, but I get no connection.

  I have the DMZ a 10.0.0.1 / 255.255.240.0
  The value 10.0.0.5 Web server / 255.255.255.240.0
  Gateway is 10.0.0.1

  DNS server on the primary domain controller 192.168.10.1

  I opened the ports following services:

  Kerberos 88 (TCP, UDP)
  Time 123 (UDP)
  135 Kerberos authentication (TCP)
  LDAP 389
  LDAP 445
  MS DS 3268 (TCP)
  1025-4999 RPC Ports (TCP)

  In the rules of the DMZ Lan, for those leaving, should I simply specify the machine side of DMZ DMZ users or do I need to specify the side Lan Lan users too?

  Then I need to duplicate these ports in the Incoming, correct?

  Any help in pointing to the relevant documentation would be great.

  No, you should not need to configure static routes, unless you have something weird going. You can check the network path by adding rules incoming/outgoing ICMP LAN DMZ (ICMP-TYPE-8, to be precise) and ping back and forth between the DC and the Web server (ensuring any intermediate software firewall is disabled). If you can test in both directions, then you know with certainty that none of the static routes are needed.

• Configuration of the DMZ and USER-BASE10

  Hello

  I've been using System DMZ1 variables... 3 and USER-ADDRS1... 5 to identify the different networks. However, I was wondering, what is the difference between the DMZ and USER-BASE10? It is in the name, or they are used in different ways by some aspects of the software?

  Kind regards

  Matt

  There is no difference. They are purely just names. The sensorApp just treats them as variables that can be used to specify filters.

• Configuration of the DMZ

  Hello

  We are now entering the last stage of our program of virtualization by looking at our internal and external DMZ virtualization.  I understand that although you can run VirtualCenter on a Windows domain server no it is not the recommended practice.   I'm looking for so some guidance on best practices for vSphere guests in two areas.

  • Should we run a stand-alone VC in a single box that manages the hosts and guests in each area.
    
  • We should use our internal VC with open appropriate firewall rules to manage the hosts and presenters.  (This is my favorite, but do not know if security would allow)
    

  Someone at - it links to best practices for the Organization in a DMZ and happy to share their experiences?

  Thank you very much

• Port number of the DMZ URL mask

  Hello
  
  I just finished the configuration of the DMZ node to irecruitment for a client module. I followed Doc Id 380490.1 for installation. The external URL for the customer is of the form http:// < hostname >: < port >/OA_HTML/IrcVisitor.jsp. Now, because of security concerns the customer wants to hide the port number of the URL and post it on the internet for the registration of external candidates. How do I remove the port number of the URL and post the URL as /OA_HTML/IrcVisitor.jsp or http:// < hostname > < hostname > http:// / IrcVisitor.jsp.

• Implementation EBS in the DMZ configuration

  Hello

  I have a few questions about implementing EBS in the DMZ:

  1 - when to choose the web option external only (Figure 4 in document 380490.1) to be in the DMZ, this external web communicate with internal DB directly or through the inner layer of Middle?

  2. when choosing this option (external web), if the middle tier internal was down, this affects the external web features?   Maybe this question is related to the first as well

  3. in Option external Web, I do all the changes made in the application by developers at the internal intermediate again in the external web?

  4 - What are the things to do mannualy in extrnal web, if it is made other than patching web internally?

  my last Question,

  Is there a solution certified in the DMZ, where I can implement only thin web (HTTP only containing only services not HTTP/OC4J) but not the proxy reverse?

  Thank you d ' attribute

  Without some such configuration is not possible - which is the reason for not using a reverse proxy?

• Out-of-Band management on the servers in the DMZ

  Hi, I have four PC7048s in my DMZ. External, internal making face and 2 separate demilitarized. Everything is good. All workers.

  Since they are demilitarized I want only their route between them and thus in position off http, Https, Telnet, and SSH management so that they cannot be managed remotely from the DMZ subnets.

  I then plugged the OOB interfaces in my internal management switch and VLAN them accordingly. Very well, now I can ping my OOB interfaces on all four. But I can't manage them because I have disabled SSH, HTTPS, HTTP and Telnet

  If I allow them (just SSH and HTTPS) I am now able to manage the switches of the DMZ on the IPs DMZ subnet

  I thought that the point of the OOB was so this does not happen and there is isolation? If I have to spend globally on HTTPS and SSH, then they are not really well isolated (I understand that OOB traffic cannot talk to IN-Band etc. - is the fact that I turn on a global configuration for remote OOB service)

  Am I missing something?

  Thank you

  Your results are correct. To lock the management more far I suggest looking to implement ACLs. With the ACL you can permit/deny access to various management services.

• RV042 impossible to disable the DMZ Host

  All trying to configure my RV042, I "turned on" the DMZ host feature (under Configuration > DMZ Host) by entering the address LAN IP of one of our machines. I think now that I don't want to actually on. According to the help page (and also the manual), he says:

  "Enter the IP address of the network device you want to use as a host DMZ." Otherwise, enter a zero (0.0.0.0) to disable the DMZ host.

  So I try to enter the address 0.0.0.0, and it gives me an error:

  

  What I am doing wrong? The instructions are just incorrect? Is there a way to disable this option?

  If the LAN subnet is 192.168.1.x/24, you might want to try instead of 0.0.0.0 192.168.1.0 to disable DMZ Host.

• second Web server on the DMZ not visible outside

  With the help of a PIX 515e

  I have several Web servers in the DMZ, the first web server and the mail server are set up with the port mapping for the PIX outside IP address of the interface.

  The second and third (inside interface) of the Web servers are configured with static mappings and access lists.

  I can see the first n the mail very good server webserver, but I can not see servers in second or third.

  What have I done wrong?

  I suggest you analysze traffic with the command to 'capture' PIX and sniff traffic on the DMZ and outside traffic.

  Check if packets arrive to the external interface, if it reaches the web server and is at - it a response.

  example of

  IP access-list 120 allow any HOST 207.236.60.35

  capture the access-list 120 vpncap OUTSIDE interface

  See the access-list 120 retail vpncap capture

  or

  https://PIX-IP-address/capture/vpncap [/pcap]

  To remove the capture:

  No vpncap capture

• 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!

  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.

• CSA on servers in the DMZ

  Hello

  I'll install csa agent on servers of DMZ. Since there is no access to the Management Center in the DMZ, access is not permitted from internal dmz, only MC (internal) can access servers. I know that the CSA can record events on the computer, the MC will be able to get back them?

  Except for a hint of polling sending, the MC is not initialize the connection for update of policy officers and events download. Agents are configured with a polling interval (default is 10 minutes), the Agent makes the connection with the MC via port 5401, and if it is not available try 443.

  For your Agents work correctly with the MC, your DMZ must allow your dmz servers to connect to your internal port 5401 or 443 MC (I prefer 443).

  Just add an ACL on your firewall so that the dmz servers can connect to only this server MC. Then you can create a rule to network access control so only the Cisco Security Agent can access the IP address of the MC on port 443.

  In this way even if the attacker has exceeded all the other rules of the csa and used the server dmz as a breakpoint for more attack, they must kill the agent first, before they could get to the MC. And if that wasn't enough, you can create a rule of access control data to the Agent installed on the MC itself, which will send you an email if the root of the https:// is accessible.
