• How simulate correctly a VM with public IP address

  Hi I need simulate a computer virtual which is connected to the public Internet with public IP addresses in VMware Workstation but don't know if I'm using appropriate measures.  I did something like this:

  1. Start the virtual network Editor, click Add Network.
  2. When the new network is created (IE VMnet2), I select "Host-only (connect VMs internally in a private network).
  3. Check the box "connect a virtual network adapter.
  4. Assign the corresponding Internet public IP subnet to subnet IP subnet mask fields and.
     Note for some reason I'm not able to use anything that does not begin with x.x.x.0.  For example, I am able to use 109.122.105.0 and 255.255.255.0, but not 109.122.105.90 and 255.255.255.248.  If anyone knows why please help us with that as well.
  5. On the virtual machine, I will then edit the hardware settings and assign the network device to VMnet2.

  Issues related to the:

  1. Is - what the right way to say simulating virtual machine running in my PC with public IP addresses?  The goal is to preserve the settings of the virtual machine without changing anything.
  2. Is traffic from my PC targeting this public IP address will be only referred to this VM and not on the Internet?  It seems that it is indeed the case, even when I'm connected to the Internet, but I just want to check if it comes to the way it was designed to work.
  3. Why would network editor virtual allows us only to 109.122.105.0/24 (IE with 255.255.255.0) rather than 109.122.105.90/29 (that is to say with 255.255.255.248)?
  4. Is it possible to visualize the vSwitches and VMnets that are running on my PC?  With vSphere client connected to ESXi, I am able to see how they are visually connected when I click on Configuration of the host and then network.
     

  1.) unless you need to access the virtual machine on the host virtual network adapter, you must create a separate vmnet.

  2.) on a single host network traffic will not stay internally. However, creating such vmnet with a virtual map of the host can prevent host access this specific Internet subnet, because traffic is routed internally.

  (3.) the appropriate subnet ID in this case is 109.122.105. 29 88(see, for example, http://www.subnet-calculator.com/)

  4.) No, nothing that I would like to know of.

• Outlook does not, Exchange is a virtual machine on my iMac with public IP address

  My iMac is connected to my switch and my switch is connected to my NVG589 of ATT modem.  My iMac draws a DHCP ATT modem and the intellectual property IP is 192.168.1.64.

  I am running VM Fusion on the Mac, version 7.1.3 (3204469) and I've updated for yesterday.

  One of the virtual machines on my iMac is Exchange 2013 and it has a public IP address.

  So, to summarize, my iMac is DHCP with a private class C address and my VM is static in a class A public address.

  Before the update I could open my outlook on my iMac and it connected to my server exchange very well.

  After the update, my vision and my iMac OWA do not work.  My outlook to connect, but it won't draw down of any mail and my own just can't OWA load.

  Exchange and OWA work from any another machine other than the iMac.

  I can't help thinking that it's something in the update that has done this because it worked before the update 7.1.3 (3204469).

  The NIC is auto detection against NAT or bridged and I haven't changed it.

  Can anyone suggest something that I have not tried?

  Thank you

• EX90 two autonomous with the public IP address can make video calls among them self on the Internet or not?

  Dear expert;

  I am very new to VCS and TP Cisco.

  We implement now presence Cisco TV with VCS - C, VCS-E TMS, TCS, MCUS and endpoints with Jabber in a single edit.

  and in another configuration CUCM 10.5, UCCX 10.5 IM & P, Jabber with some 10 officers.

  Now the question is in our building on the 2nd floor we have an EX90 and on the 5th floor an EX90 and on local network, we can make video calls using the IP address.

  In the same way is it possible to make a video call between 2 devices EX90 (both have public IP) present in a location different in the same city on the Internet without the participation of VCS - C and VCS-E.

  It's the client request :)

  Yes, but leaving these systems outside in nature with public IP addresses, leaving you are vulnerable to a number of questions. See for example http://www.videonationsltd.co.uk/2014/11/h-323-cisco-spam-calls/

• Flex publish / subscribe does not public IP address

  I installed the last Flex Express LCD on top of ColdFusion 8 enterprise demo installed as JRUN/multiserver and got it all to work when you run directly from the server using the "' http://127.0.0.1:8300 / samples". " However, when I run outside with public IP address of the server, then everything works except for samples of publsh/membership push. They just hang and impossible to subscribe. Any ideas? What is a restriction on the LSCDS Express or the CF8 demo version? Or maybe a port problem? We have all ports closed except for those needed. There is an additional port that is to be opened in addition to 8300? Thanks for any help.

  I think I found the problem. It seems you must have port 2037 open for RTMP to work e-mail with sample apps. This port is closed on our firewall and I suspect that's why I'm having a problem. I'll get my network guy to make the change on Monday and then I'll try it again. Probably that it will solve.

• Configure the router WRT54G with the PUBLIC IP address and use the DHCP protocol for internal computers

  Hello

  I have a service online Internet with 5 public IP addresses.

  The router and the AP are connected to a switch.

  I would like to set up a WRT54G Router with a public IP address and use DHCP (with private ip address) for the computers that will connect to the AP.

  That the AP is connected to the switch, it is possible that the other wired computers that are connected to the same switch can get an IP from the DHCP?

• Site to Site VPN between ISR4331(Data Center) and 25 branches with RV042 and dynamic public IP address

  Hi, we just got router ISR4331. We will use this router to our datacenter as pummel hub. Not to mention that it will be the static IP address. Our goal is to connect 30 small offices to the Datacenter by VPN site-to-site. All of our offices a RV042 router and DSL connection, so dynamic public IP. How to accomplish this task.

• L2l VPN between ASA with the IP address public and CISCO2911 behind the ISP router with port forwarding

  Hi all

  My apologies if this is a trivial question, but I spent considerable time trying to search and had no luck.

  I encountered a problem trying to set up a temporary L2L VPN from a Subscriber with CISCO2911 sitting behind the router of the ISP of an ASA. ISP has informed that I can't ignore their device and complete the circuit Internet on the Cisco for a reason, so I'm stuck with it. The Setup is:

  company 10.1.17.1 - y.y.y.y - router Internet - z.z.z.z - ISP - LAN - 10.x.x.2 - XXX1 - ASA - 10.1.17.2 - CISCO2911 - 10.1.15.1 LAN

  where 10.x.x.x is a corporate LAN Beach private network, y.y.y.y is a public ip address assigned to the external interface of the ASA and the z.z.z.z is the public IP address of the ISP router.

  I have forwarded ports 500, 4500 and ESP on the ISP router for 10.1.17.2. The 2911 config attached below, what I can't understand is what peer IP address to configure on the SAA, because if I use z.z.z.z it will be a cause of incompatibility of identity 2911 identifies himself as 10.1.17.2...

• Configure my VCSC with VCSe on the public IP address

  Hi guys,.

  I have a session of control VCS under my company Private IP and I my client on public IP VCSe.

  It will be possible to configure my VCSC with the VCSe after the configuration of the areas?

  The ports must be opened by my team of firewall in this scenario?

  Anything else I need to keep in mind.

  For the record, it is only for the objective test.

  You will appreciate any response.

  Thank you

  Saurabh

  > Then, practically there is no as such risk, and my client can use the public IP address on VCSe

  > without going to double network Option key. (which is used to secure more VCSe).

  Cisco highly recommend VCS-E deploy under the DMZ but it's true, too, many customers deploy VCS - E on public network directly.

  Please visit https://supportforums.cisco.com/thread/2154738?tstart=150 for more information security VCS.

  Next version of the plan to be supported VCS X7.2 software build - in the characteristic basic firewall, which allows configuration to allow/deny list based on the IP / port / protocol which should contribute to better security level or even VCS-E deployment on the public network directly.

  > So, I'll ask my client just buy a public IP address, that's all, and we are ready to go?

  A public IP will demand on VCS Expressway, VCS control can be use the NAT address glow (IE share internet access of the network of offices).

  You must also SRV DNS management (if small deployment probably better to use the external DNS service, there are a lot of company provide a service the two service also responsible DNS hosting and as free service).

• Cisco AnyConnect VPN connection has not changed my public IP address on Windows 7 64 bit

  Hello

  I installed a customer Cisco AnyConnect VPN from my school, so that I can access school of my Windows 7 laptop at home network. I was able to connect, but when I used http://www.whatismyip.com/, it still shows the IP address assigned by my ISP.  The "network and sharing Center", I have my original LAN and LAN VPN upward but access to LAN VPN type is 'without Internet access. The VPN connection seems to have activities based on evolution bytes sent and received.

  I searched the Web for solutions and changed something like adding the entry door. But it did not help.

  Thanks for your help.

  Split tunnel is probably configured so that traffic destined to school networks pass through the VPN tunnel, and traffic destined to the Internet goes outward through your local ISP. That's why whatismyip show your public IP address from ISP.

• VPN site to Site on firewall with no public IP address

  Dear all,

  I have a VPN from Site to Site configuration requirement with accommodation, I have my internet connection on the router termintaed and got only a single public ip address. My ASA is behind this router with no public IP (attached chart). This router will not support VPN and I need to configure VPN on the firewall.

  192.168.20.0/24 is the network between the router and firewall. 192.168.10.0/24 is inside the network. (attached diagram have the most details)

  Please advice the configuration to achieve this...

• EBS 12i on Cloud server with the public IP address but no DMZ

  Hello

  I installed Oracle EBS in a server (such as AWS EC2) cloud with a public IP address. I'm simply looking for personal learning and knowledge about security risks. As there is no given production safety is not serious at this point.

  Also, I don't mean to enter the configurations of the DMZ at the moment.

  I am able to access APPS internally under the server on port 8000 with URL http://<server:8000>/OA_HTML/AppsLogin. but I'm unable to access the URL above on internet.

  
  

  The environment is EBS 12.2.0 on Oracle Linux 5.11.
  

  
  

  I tried the options following, but so far without success.

  1. I tried to completely disable the Linux and SELinux firewall on the server. I have also authorized above URL in my personal office. So the 8000 port is not blocked anywhere.

  2, I followed this note to try to set it up on port 80, but still without success-> configuration Oracle E-Business Suite Release 12 on Amazon Cloud Infrastructure (Doc ID 1205963.1). But you should know that mine isn't on AWS EC2 but similar model.

  So simple question is how can I access front-end EBS on internet (DMZ) using port 8000? I do need to update httpd.conf of EBS Webtier (besides point 2 above)?

  Any help will be greatly appreciated. Thank you.

  See you soon!

  Hello

  I discovered that I was using the CDN was blocking port 8000. So when I bypassed the CDN, then I could manage to access the URL with the port 8000.
