DMZ

I set up a DMZ on an ASA 5500. I can access the web server from the internet and cannot be accessed from the inside network.

The DMZ is to use a network of 10 and static nat to a registered IP address. Inside network uses a network of 10 different. I can't access the web server with 10 net address or registered address. Inside users should not simply be able to enter the address of the web site and be able to get on the server?

I am doing the config using the ASDM program.

Any suggestions?

Thanx, Seth

I understand...

You will not be able to hit http://www.xxxxxx.com if it is resolved to an external ip address of the inside of the firewall. You should use dns doctoring (if your home users use an external dns server) or use destination NAT. Destination nat statement which I wrote above will allow internal users to use the public.ip from the inside of the firewall and the firewall will translate this the private address of the DMZ.

If www.xxxxx.com decides to 1.2.3.4 and the ip address of the server in the DMZ is 10.2.1.1 then you must...

static (dmz, inside) 1.2.3.4 10.2.1.1 netmask 255.255.255.255

  • 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.

  • Why would I need to DMZ router to scan?

    If you feel you have tried everything to get the scanner to communicate with the computer and nothing will do, a service representative can tell you to DMZ the printer.  Often I have heard the term used loosely, and it can be very confusing if taken the wrong way.  That's why I deliberately formulated my question as I did.  First of all, you don't want the router DMZ.  You want to DMZ IP address of the printer in the router to open ports which also insist on remaining blocked.

    I considered all the reasons, we'd lose communication with their scanner.  The reasons are plentiful and can leave a user struggling for hours trying to get their scanner to communicate with their computer.  After that a standard troubleshooting is complete, they turn to their router.  Of course, this message only relates to people who have their printers attached to their computer with an Ethernet cable or wireless.  Before I define exactly what means DMZ, first of all I want to look at why you want to do.

    Printers to communicate through several different ports.  Often routers are configured with an internal firewall to protect users of computers from outside attacks.  In this way, the only information that the computer receives comes from what the router allows through.  People might DMZ their computer for games purposes, but it would be a very bad idea.  People are misled by "reliable companies," which suggests this in order to access their personal files.  Essentially, the goal was really to contain the amount of traffic actually pass through the router at the same time so this is a feature of security and service.

    A printer has been designed to communicate through a series of ports, but sometimes these ports are blocked.  Maybe the router is due for an update, or a firmware update was conducted which could cause the printer to lose communication.  Often, people can still print which is what it makes it even more confusing.  Ports of printing are simple and well known in the world of routers.  However, scanners to operate on a level more complex.  Information is received by a port and another goes out.

    Some companies may even install a proxy server in order to reduce bandwidth and record or monitor traffic which is an example of a blocked port.  In addition, as an extra level of protection, routers differ in the configuration so that it is difficult to gain access to a network for malicious purposes.  Depending on the router and other sources of firewall, like on the computer (antivirus software and Windows Firewall), these ports may deny access to a device of 'unknown' otherwise on what seems to be a random basis.  Of course, it is not random, but the timing is always impeccable none-the-less.

    DMZ printer (also known as the port forwarding in some cases) would mean completely open all the ports of this device.  It stands for demilitarized Zone.  Open ports in this subnet to the router allows access without any additional security.  That's why doing it on the IP address of the computer is a bad idea because that which allows people outside access to your computer network.  With ports closed here, they are allowed access by the user as a download in an email that contains a virus.

    On a printer, there is no way to access the files, install viruses or damage to the printer.  Especially if it's just a home network, the risk of attack is null.  It's not as if they could tap into your network as long as it is password protected initially.  The pirates have honestly no reason to print on your printer, in order to open the ports for access to the printer is perfectly acceptable and safe.  Now, if you were totally to the DMZ the router, then Yes, but a advanced user would know the term, just so the application, expresses or misunderstood is still virtually impossible to do the entire router.  Instead, just follow these steps so that you know that there is nothing blocking the scanner to work.

    Because routers differ from a product, a non-technical person would better communicate with their provider internet router service or undertaking for them through the steps on how to do.  Directly into the router just looks like a bad idea if you have never done it before.  Sometimes the router companies will help you for free if you are in warranty, if not the biggest complaint I hear is that they want you to pay xx.xx amount to do what your internet service provider must be able to do it for free.  If you find that you are unable to find someone to do it for free, you can always search the router manual and find information in the title of port forwarding.  However, that information is not openly scattered on the world wide web because of the risk factor to plug the wrong numbers and completely block the communication with the printer.

    After I uninstalled the printer, temporarily disabled the startup and anti-virus programs, reinstalled the printer software and find I'm still able to analyze, the next thing I look at is the router.  A technical agent on the phone, I didn't have the right to access the 3rd party software and hardware, that I have been trained, so I sent an email, which included all the ports, the printer uses and at the request of a reminder.  You can just go down the list of ports and follow the instructions on how to open each one individually, or you could just DMZ IP address which opens all ports on the printer.  Seems easier to DMZ it or what is even easier to do just told someone else to do not understand the definition themselves.

    As I said, it can be confusing and frustrating, especially if it is beyond your level of troubleshooting, but everyone who has managed to do, so always the spokesperson saying they could analyze now.  9 times out of 10 it worked.  And at that time, he remained effectively resolved.  With regard to the other 10%, they had other issues inside the computer as well.

    So, if you are already in this situation, contact your router or your ISP company for how to do this.  Here is the list of ports that I would include in my email, which would also suggest updating the firmware on the router first, and then going on with port forwarding.  This is all from my understanding and experience, I learned this. It's rather simple information that I hope will help you understand why someone would tell you to do.

    Incoming (UDP) ports are ports of destination on the computer while outgoing ports (TCP) are ports of destination on the HP printer.

    • Incoming (UDP) ports: 137, 138, 161, 427

    • Outgoing (TCP) ports: 137, 139, 427, 9100, 9220, 9500

    The ports are used for the following functions:

    Print

    • UDP ports: 427, 137, 161

  • LRT214 - routing of DMZ

    Hello

    for some reason I can't connect from the DMZ network to the internet.

    Installation program:

    Internal network: 192.168.0.0/255.255.255.0

    DMZ: 192.168.100.0/255.255.255.0

    WAN: connected to the cable-modem (DHCP)

    Even with the firewall disabled.

    So, for me, it seems that the unit is not "Routing" of the demilitarized zone.

    At the moment I activated the firewall again and added two rules to give them access DMZ:

    1 REFUSE all traffic to DMZ (any) to 192.168.0.0 - 192.168.0.255 (to deny access to the local network to DMZ)

    2 ALLOW all traffic to DMZ (any) to EVERYTHING (in order to select "WAN" here, would be great!)

    I had this problem before in the local network.

    But I could solve this problem when I switched the "operating mode" 'router' for 'bridge '.

    [Just a little note: after Linkysys support told me that the device if default!]

    BTW... so far, I found no clue about the difference between these two modes.

    Thanks a lot for your support

    Who was I had the suspicion on the VLan to.

    But I think that it is not completely right... you have a DMZ with a privat-ip-area, but these DMZ servers do not have access to internet (NAT number of DMZ in WAN) possible.

    To be honest, I find the DMZ - of the implementation of the very strange LRT214.

    No one expects such an implementation! And IMHO, this does not meet the definition of DMZ (see wikipedia).

  • LRT224 DMZ ACL

    Hello

    I have a bit of a strange situation that I can't actually know. It's probably something I'm on, that I'm usually on enterprise-class

    My current situation:

    1. WAN1 with an external static IP address.
    2. LAN1 switches in pool addressing of class a.
    3. DMZ connected to the addressing of class B pool (/ 29 subnet)

    Port forwarding pushes some ports to our Exchange/Intranet site on class A.

    Port translation pushes a TCP port that is customized to a specific machine in class B.

    Class B cannot access class A, the opposite is not true. This is normal.

    Class can access the internet, a specific class B machine cannot. This is false.

    How I configure my ACL:

    DENY all traffic to DMZ port. subnet class B source, destination one subnet of class.

    ALLOW all traffic on the DMZ, source ANY, internet destination port.

    ALLOW all traffic on port WAN1, subnet of class B source, destination ANY,

    ALLOW TCP port custom port WAN1, source ANY, a specific destination IP address in the class B (DMZ).

    ALLOW all traffic on the LAN, ANY source, ANY destination port.

    DENY all traffic on the DMZ port, source ANY, a class of destination subnet.

    Furthermore, and I noticed in fact just that, why it's split between WAN and WAN1? Could be the problem?

    As I know the DMZ does not work the way you use. Isn't the range of private IP addresses to public IP addresses for your servers to use instead of a range of IP addresses. The DMZ LRT is different from other standard model of the DMZ.

  • E4200 v1, DMZ and PS3 game system

    I had a question regarding the use of the DMZ on the router for use with the Playstation 3 game system.  More like a probe for your reactions.  The pro, con and all the rest.  Last week (I think), I posted about problems streaming movies and TV shows through services such as Netflix, VUDU, etc..  I thought using the DMZ feature on my router to expose all the ports for the PS3.  I know I should set address static IP for the PS3 (not let automatically obtain an IP address, that is not a problem), but I wonder if someone has done this, what the results were, what the potential pitfalls are, etc.  I never heard talk of a PS3 being hacked with the exception of the Playstation Network being hacked last year, but which is a service for the PS3 to connect to, does not part of the PS3 itself.

    Anyway, just wanted to get some thoughts on this subject here and there.  I thought that if maybe it's a problem of open port, using DMZ could solve this question Lickety-split.  Constructive comments are always appreciated.  Thank you!

    BTW, as before, I have the latest firmware, the latest updates on the PS3 itself and the latest app updates that I can get to Netflix, VUDU, etc. on the systems themselves.

    The 1st thing you should consider is your modem. What is a simple modem or a modem/router. If it is a modem/router, then you must put the modem in full bridge mode and configure PPPoE on your router. Then what of the DMZ, as all ports will be opened then you will leave your router vulnerable to attacks, try port forwarding instead. Simply enter the ports for PS3 w / address static ip that you set on your PS3.

  • EA4500 - DMZ does not!

    Need help!

    I had a program running one of my computers.

    Need to be accessible outside of here.

    I put the DMZ at 192.162.1.100 (which is the ip address of the runing machine program)

    MY ISP got a static IP address. Used to work with my old WRT54G... don't know what I have to do to access outside of my working group.

    The program on the machine uses port 8600.

    Not lucky to get this thing to work up to now

    You should also check if your modem is a gateway(modem-router). If it's a gateway, it will also block the ports that you try to open on the router and may need to ask your ISP to set the bridge in bridge mode. Also, turn off the anonymous filter request under Security > Firewall tab. I also recommend to disable the DMZ (for security reasons).

    Simple Port Forwarding.

    Both external and internal 8600 Port IDE oucederomsurlesecondport value.

    Set the Protocol at a time and

    Use the IP address of the computer using the software.

  • WRT160N V3 DMZ and Port-Forwarding does not work

    Hi all

    I have a V3 WRT160N and DMZ or Portforwarding do not work.

    I tried on locally

    WAN_PC-> WAN - PORT-> WRT160N V3-> LOCAL - PORT-> LOCAL_PC

    The WAN_PC has a static IP 192.168.1.2, subnet 255.255.255.0

    The WAN PORT has a static IP 192.168.1.1, subnet 255.255.255.0

    ON the WRT160N V3, I set up a DMZ on 192.168.0.100.and off the firewall.

    On the LOCAL_PC (192.168.0.100:8888) is an Apache

    So when I type 192.168.1.1:8888 on the WAN_PC I get NOOO the Apache on 192.168.0.100:8888 Web site?

    WHY??????????????

    Please correct me if I'm wrong. My understanding of your installation, it is that you have a computer connected to the internet port of the router and another computer connected to the router's ethernet port? Is this correct? You don't have a modem for internet connection or something like that? If you can post here a diagram that will be better. Thank you.

    Hope this is the right place for this question.

    I have a WAG200G and a WAG54GS. I would like to connect routers to another, each of them would be on a different subnet, creating a DMZ on 192.168.1. *. Or the other could serve as the "internet" router i.e.

    INTERNET <-->ROUTER1 (192.168.1.1) <--LAN-->ROUTER2 (192.168.0.1)

    |                                                                    |

    DMZSERVER (192.168.1.2) PC1 (192.168.0.2)

    Is this possible? I can't find a "internet connection type" on each router that says 'just use ROUTER1 for your internet connection.

    Thanks in advance

    You can replace one of the ADSL router with a normal linksys router as WRT54GS, WRT320N WRT54G2, WRT160N... And then you can the two router cascading and create two different subnet.

  • RV042 Dual WAN Port DMZ not acquire an IP from ISP

    Hello

    I am trying to replace my router with the more robust RV042 of current load balancing. Installation seems simple enough. However, I am having an issue gets an IP address of the DMZ port in load balancing mode.

    The two WAN is the same ISP and is both DSL, using the same models of DSL Modem. #1 WAN port works perfectly.

    Indeed, when an independent piece of equipment is installed in the #2 DSL modem, this gives an IP address instantly...

    The two DSL lines only require a MAC address to get their IP addresses, and none of the static values are allowed, perhaps to test only.

    The issue of intellectual property has been seen before. I can't find any reference to the iton this site.

    Thank you

    Glad to hear that it works.

    The "save the settings and restart" is not all that rare, although it is not typical for your model.

    The obligation of power off is certainly not normal. He told me that some sort of electric lock has occurred. This could be a unique thing, caused by a discharge of static electricity, or it could indicate a manufacturing defect. If this is the first case he did re - is probably. If it is the latter, then it will need a trade at any given time.

    In any case, it seems that the MAC address index has been at least partially useful.

    Good luck, somone will be here if you need assistance once again.
