traffic to DMZ for outside

• 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.

• Hide no port. for outside users

  Hello

  I have a cisco ASA 5520 appliance. Now the situation is I have a server in my interior of networks and this server is coordinated with the public ip address and activated port.so 2010 which, apart from the user can access the site to web server via the port of 2010. Like this.. http://Server URL: 2010

  Now I want hidden port ELE for outside user. means they can get access without attributing any port no.like: url http://server

  How is it possible, pls help me...

• Tunnel VPN ASA 5520 (DMZ + INSIDE) destined for OUTSIDE

  I can't find any reference to anywhere else.

  We have an ASA 5520 to our site HQ (inside the network) with several regional subnets on the DMZ interface.

  We need connectivity VPN Site to Site between the INSIDE and a remote control on the OUTSIDE of the site, as well as between the DMZ subnets and even outside the site. The interface from the OUTSIDE of the SAA must be local VPN endpoint for all tunnels.

  I created a S2S VPN between the INSIDE and the OUTSIDE site and it works great.

  When I create a VPN S2S tunnel between a site of DMZ and even outside the site (using the same settings the and remote, but with a cryptomap different because the local subnet (DMZ) is different from the other inside the subnet, the traffic gets the mapping (show crypto isakmp his) to the same cryptomap that was created for the access to the tunnel from the OUTSIDE) , instead of to the new cryptomap, so remote endpoint deletes it, and traffic also causes SPI incorrect of for the remote endpoint, which makes the original INTERIOR outside OF THE VPN tunnel to fall from time to time.

  Is this a bug?

  I also did a local S2S VPN tunnel configuration test of networks as everything INSIDE and the DMZ. With the help of the wizard VPN S2S leads ASA only to create a NAT rule exempted for the subnet on the INSIDE interface. Can I manually create another tax-exempt NAT rule to the side of the DMZ and use this a S2S tunnel to connect sites inside and DMZ to the remote OFF-SITE in a connection profile?

  I'm building a Rube Goldberg?

  Thank you

  George

  Hi George,.

  It seems you have a situation overlapping it, are you sure that subnets inside did not overlap with the networks from the DMZ?  A package tracer could clarify wha that the ASA is actually sending.

  In addition, you can merge the two interfaces on the same card encryption if you wish, just make sure that the NAT is configured correctly.   For example; Source NAT (all, outside) static...

• ASA 5505 DMZ for the guest wireless access

  Hello

  Here is my delima:

  I'm deploying an Apple Airport Extreme BaseStation with Airport Express 7 "repeaters" throughout my network/building. Apple only allows only two wireless networks, public and private. Your selection of only can 192.168.x.x, 172.13.x.x or 10.10.x.x for each subnet. NO tagging VLAN.

  It wasn't my decision... Apple CEO hs fever.

  So Im stuck on how to implement this without VLAN. The comments/public subnet needs to be isolated outside access. While the private subnet requires access to both.

  Any suggestion would be greatly apprecaited.

  What will the Security Plus license allow me to do?

  Security over the license allows the use of circuits for the ASA 5505.  It also increases the maximum number of VLANS configurable at 20.  Allows active failover / standby and increases the number of authorized IPsec VPN tunnels.

  The problem with the basic license is that you can have 3 VLAN configured and the 3rd VLAN is a VLAN 'restricted '.  This means that you can not pass traffic to or from inside VLAN on the 3rd VLAN (or DMZ VLAN if you prefer to call it that.)  So this VLAN DMZ won't be able to communicate with the internet.

  So, if your private wireless network and the local network will be on the same subnet your public wireless network can be in VLAN 3.  If this isn't the case, you will need to get the security over the license.

• VPN traffic to dmz

  I have several leading to a 5510 Firewall VPN sites. all work well, but I can't get the traffic from sites VPN to communicate with a server on a DMZ on the same firewall.

  a trace of package from outside the demilitarized zone shows this:

  Type: VPN
  Subtype: encrypt
  Result: DECLINE

  Ive configured access to the the same demilitarized zone on servers inside. I can get inside okay servers.

  any ideas?

  You have to clear the VPN tunnel down after you have added the new DMZ subnet to the ACL crypto? and I also assume that the remote end has added the same ACL mirror image for their ACL crypto?

  Finally, I also assume that you have configured NAT exemption on DMZ interface and run "clear xlate" after the config?

• DMZ FOR LAN

  IF I HAVE APPLAIANCE ON DMZ LETS SAY OF E-MAIL SECURITY... DO I NEED TO ACL OR NAT BETWEEN THE DMZ TO LAN POLICY?

  OR SIMPLY POLITICAL NAT AND ACLS OF THE WAN TO DMZ... AND DMZ TO LAN WILL SPEAK WITHOUT INTERRUPTION

  You don't need a policy of NAT, DMZ - LAN, only ACLs, which will allow traffic from the local network to your device in the DMZ.

  You must configure the NAT policy and an ACL while providing access outside your network form. That is to say, WAN - LAN or WAN - DMZ.

• AIP SSM-10 - how to check traffic being passed for inspection?

  Hello

  I've implemented an AIP - SSM on our ASA5510 for the first time, as a result of this excellent guide, http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a00807335ca.shtml.

  The difference between the environment used in the doco and ours are the specifications of our ASA and module, the following IOS version 8.0 (4), version ASDM is 6.1 (3), the version of the application of SSM is 5,0000 E2.

  I have followed all the steps to enable connectivity to the module of the ASDM, created the access list to allow all ip traffic to be transmitted to the inspection module, map of the class and the political map indicating promiscous mode, relief. The service policy is applied throughout the world.

  The problem I'm having is that when I try to check as indicated on the guide to the alert of events see the command on the CLI module I don't get any output, so I don't know if the traffic is passed to the module. Can someone plese help me clarify this?

  Kind regards

  Esteban

  Run 'show conf' on your AIP SSM CLI. Check interface GigabitEthernet0/1 basket of the MSS background assigned to sensor virtual vs0.

  If it does not, then run "setup" and towards the end of the installation wizard, there will be an option to change the interface and the virtual sensor configuration. Use this option to change the configuration for sensor virtual vs0 and in the interface.

  You can also run "show stat vs0 virtual sensor" to see the number of packets being crawled by vs0.

• can I connect port 2 of my WLC 4404 in my dmz for access to guest user

  Hi all

  My script is

  Cisco wlc 4404, with 20 access points, I want an internal client wlan and wlan of comments, I configured the VLAN and WLAN, but would be possible to have all the internet traffic for customers going to port 2 on the controller of the demilitarized zone of my firewall? How I would get this job, coems from traffic to the ap through a port on the controller.

  Help, please

  see you soon

  Carl

  Carl,

  You must have two interfaces AP-Manager because you connect physically two ports of distribution on the WLC.  When you do this, you must use LAG (that you can not do in the case because you connect to two different switches) or have an ap Manager assigned to each port (this is how you can have the switch redundancy).  So yes, it will allow you to do. Please see the link guide to config I have sent for more information on the use of multiple ap interfaces - manager.

  The WLC knows that he has to send the traffic comments port 2 because WLAN guest is assigned to the interface of comments which, in turn, is assigned to port 2.

  Again, I strongly recommend that you open a TAC case, so you can speak with an engineer and discuss this because as you can see, it can be bit confusing

• Traffic Internet PIN for router ACL

  Hello, I create a router-on-a-stick typical configuration where remote locations running IOS Cisco direct Internet traffic out through an IPSec tunnel that ends on an ASA5510. I'm 99% it and can't seem to move between the rays and the Internet. I'm looking for advice on how to configure properly the ACL entering the router WAN interfaces spoke.

  My question is, what I specifically authorize the return of Internet traffic in the router speaks ACL? I was under the impression that what allows the Hub ASA IPSec traffic would include traffic Internet has hairpined through the ASA and I wouldn't need a specific ACL entry to addresses of Internet sources.

  The router has spoken, I work now is a 3620 running IOS 12.3.26. When I configure the ACL entering on the WAN Interface to allow only the esp/isakmp Hub ASA, I'm not able to receive traffic from the Internet. If I remove the inbound ACL everything works fine. Here are the current incoming ACL from the laboratory network router:

  access-list authorized note 130 incoming WAN connections

  Note access-list 130 IPSec

  Note LAN Access - list 130 subnets

  access-list 130 allow ip 192.168.75.0 0.0.0.255 192.168.168.0 0.0.0.255

  access-list 130 allow ip 192.168.50.0 0.0.0.255 192.168.168.0 0.0.0.255

  access-list 130 allow ip 10.199.199.0 0.0.0.255 192.168.168.0 0.0.0.255

  Note access-list 130 HUB ASA

  access-list 130 permit udp host 172.16.1.4 host 172.16.1.21 eq non500-isakmp

  access-list 130 permit udp host 172.16.1.4 host 172.16.1.21 eq isakmp

  access-list 130 allow esp 172.16.1.4 host 172.16.1.21

  access-list 130 allow host 172.16.1.4 ahp 172.16.1.21

  Note access-list 130 NTP to the router

  access-list 130 permit udp host 192.43.244.18 ntp host 172.16.1.21 eq eq ntp

  access-list 130 authorized note ICMP traffic

  access-list 130 permit icmp any echo host 172.16.1.21

  access-list 130 permit icmp any any echo response

  access-list 130 permit icmp any any source-quench

  access-list 130 permit icmp any a package-too-big

  access-list 130 allow icmp all once exceed

  access-list 130 refuse icmp a whole

  access-list 130 authorized note circulation of Managment

  Note 130-list of access allow ssh

  access list 130 permit tcp any any eq 22

  With the list above applied inbound access on my WAN Interface, internal hosts are able to ping Internet addresses (allowing a response to ICMP echo) but cannot browse the Internet.

  Should I enable a firewall on the router policy to allow the return of the Internet traffic? I thought that rule of ESP permits that would cover.

  Any help is appreciated!

  Unless you're running the IOS Firewall feature on your spoke routers then the router is unable to keep the State of outbound connections. So yes, you will need to also allow the traffic unencrypted in your inbound ACLs on the WAN interface because once the traffic is decrypted, it is then checked against the acl on the interface, see this link to order operations.

  http://www.Cisco.com/en/us/Tech/tk648/tk361/technologies_tech_note09186a0080133ddd.shtml

  On ASA/Pix firewalls you can tell the device to check against the acl on the external interface once that traffic has been decrypted with the command "sysopt connection" but I'm not aware of a similar option for IOS.

  I would try using a different acl for your tunnel of split, it is always advisable to separate your ACL.

  vpngroup split tunnel 102 touavpn

  access-list 102 permit ip 10.10.12.0 255.255.255.0 10.10.15.0 255.255.255.0

  access-list 102 permit ip 10.10.11.0 255.255.255.0 10.10.15.0 255.255.255.0

  access-list 102 permit ip 10.10.101.0 255.255.255.0 10.10.15.0 255.255.255.0

  access-list 102 permit ip 10.10.14.0 255.255.255.0 10.10.15.0 255.255.255.0

  I would also get rid of what you don't need...

  IP 10.10.15.0 doesn't allow any access list 101 255.255.255.0 10.10.12.0 255.255.255.0

• Unable to SSH for outside the router No. 2851

  Is there anything else that I should consider when setting up SSH on the external interface?

  TIA,

  Michael

  I notice that there is a card encryption on the interface (I have would have supposed of your previous comment that you access the router via VPN) and I wonder if it is possible that SSH entering your remote address is considered to be entering the card encryption VPN traffic. Could you try the external address of some other address source SSH and see if that changes things?

  Or can you provide details on what is in the card encryption - and perhaps think about putting something in the map encryption that would exclude SSH to the external interface.

• Translation NAT PIX problem

  Hello everyone I have the following situation on a running 6.2.2 PIX 520

  I have three interfaces inside, outside, dmz

  on the external interface have an access list to allow icmp from the IPs behind the DMZ interface, I have the following:

  external_access_in list of access permit icmp any 1.1.1.0 255.255.255.0

  NAT (dmz) 0 1.1.1.0 255.255.255.0 0 0

  Access-group external_access_in in interface outside

  1.1.1.0 are routed over the internet, ip addresses of the foregoing allows external hosts don't ping my hosts behind the dmz interface

  I'm doing the same thing try to allow hosts behind the area demilitarized the hosts behind the inside interface to icmp ping:

  dmz_in ip access list allow a whole

  NAT (inside) 0 1.1.5.0 255.255.255.0 0 0

  Access-group dmz_in in dmz interface

  The Interior allows entering by default.

  But I have the newspaper:

  305005: no group of translation not found for icmp src dmz:1.1.1.1 dst domestic: 1.1.5.1 (type 8, code 0)

  In my view, the situation is the same thing as the ping outside the demilitarized zone.

  I have:

  ethernet0 nameif outside security0

  nameif ethernet1 inside the security100

  nameif dmz security50 ethernet2

  Could someone tell me where I'm wrong, and how to allow the demilitarized area welcomes guests inside interface to icmp ping.

  Thanks for your replies.

  When you use "nat 0" with a network after him, it does NOT work as a static/ACL combination that normally, you need to move from a lower to a higher security security interface, as you do here. With "nat 0", traffic not from higher security first interface, THEN traffic can flow from the lower security interface. In your example, the traffic should flow inside the DMZ BEFORE traffic flows from the DMZ to the inside. The reason it works with the DMZ to outside traffic is that traffic probably sank DMZ for outside already, while traffic then flows from the outside to the DMZ.

  NAT 0 is probably something I would keep away from, could the interpretations of the causes like that. IT is IS NOT THE SAME AS STATIC/ACL PAIR., although it is similar.

  I would replace your statements "nat 0" with the following:

  > static (dmz, outside) 1.1.1.0 1.1.1.0 netmask 255.255.255.0

  > static 1.1.5.0 (inside the dmz) 1.1.5.0 netmask 255.255.255.0

  You have still a static, but you translate it into himself, effectively bypassing NAT (even though it still go through the NAT process). Traffic will then be able to move back and forth without worrying. It's easier to read and follow for me too, but that's just my opinion.

• problem; No secondray of ip address allowed on PIX

  Hi enfineers;

  I have 3 email server on the inside, outside and in the demilitarized zone.

  each of them must communicate with each other .i gave inside an invalid ip address.

  DMZ and oueside each of them have a valid but in another range to achieve a purpose.

  So what I have to do special dmz and outeside communicateable.

  any comment is appreciated.

  Hello

  So what I understood from your email

  -You have 3 email servers. Each of them is inside, outside and dmz and you want to make communication allow all three.

  If the above is the case, then don't forget the following rules

  -If you go to safe area higher to the lower security zone (inside the area demilitarized or inside outwards or dmz for outside) so you must use nat and global declarations

  -If you come from security zone than the security zone higher (like outdoors indoors or outside dmz or demilitarized zone, inside) then you must create static translations for the machines that you want to make visible to the lower security areas and open the access list for those who translated the IPS with the correct destination ports.

  Hope the above helps

  Thank you
