• Not enough external IP for external network access

  Hello

  I am a newcomer to Lab Manager and my Department has not enough IPs to work until several virtual machines on LabManager. If we think about the use of private network as 192.168.x.x address to create a configuration and we checked which is supported using the virtual network model. But the question is whether I would like that all the virtual machines in this network is able to access the external network vLabManager will try once again each of the virtual machines assign an external IP address that we are lack of.

  So my question is the gateway for network in a configuration can be used as a router a provide NAT to allow virtual machines in a network deprived of access to external sites? Or other solutions better to solve our problem of IP all allow the virtual machines to access the external network?

  Thank you.

  The previous reviewer mentioned that NATing is supported (VMware calls this "fence"). If you are exposing ALL the machines in your configuration on their own fenced address, you will not get IP address consumption savings you want. To reduce the number of IP addresses externally exposed in a NAT configuration, you should design your configuration so that only a single IP address is exposed through the fence. A similar debate along these lines took place here: http://communities.vmware.com/message/1245907#1245907

  In a configuration of 4 machine you can put 4 machines on a network "dark." One of these devices will have to be multihomed on two networks. The hosted machine multi risk exposing his unique IP address either on the network or through a closed network directly. In both cases, only a single address would be exposed on your external network and you can use it as a gateway into the 3 other machines.

  Would be nice if the router fence could be directly configured to support some simple flavor of tunneling. Currently this capability is not there.

• Network access suspicious iPad Port 35837

  I saw my router logs - I get a lot of access LAN since IP addresses suspicious to my IPAD on Port 35837 (such as 1-4 attempts per minute) - verification of the web, these IP addresses come from Latin America and Eastern Europe - two questions:

  1. an idea of what is currently running on this port, or how I can check

  2. How can I block a specific entry on the IPAD port

• Configure the public traffic network IP inside the internal network itself and not to the external network

  A server is now accessible from external network access using the IP and port in browser below http
  http://x.x.x.x:8080

  For the same, we have configured (static NAT) port forwarding in cisco security 1905.

  The application is also accessible via IP and the internal network port internal (ie. http://y.y.y.y:8080)

  Is there a way I can configure my 1905 Cisco as well as internal network (ie. machine B) I can access the application using the IP and the public port and not with the IP address internal? From now on, I'm not able to do the same.

  The current configurations are as follows:
  access-list 1 permit y.y.y.0 0.0.0.255
  IP nat inside source list 1 interface GigabitEthernet0/0 overload
  IP nat inside source tcp static y.y.y.y 8080 interface GigabitEthernet0/0 8080

  Hello

  You can try Domainless Nat.

  no nat ip within the source list 1 interface GigabitEthernet0/0 overload
  no nat inside source tcp ip static y.y.y.y 8080 interface GigabitEthernet0/0 8080

  int gig0/0
  no nat inside ip
  activate nat IP

  int gig0/1
  no nat inside ip
  activate nat IP

  IP nat source list 1 interface GigabitEthernet0/0 overload
  interface IP nat source tcp static y.y.y.y 8080 GigabitEthernet0/0 8080

• How can I make sure that any firewalls (versions of software or hardware) does not block port 443 to access?

  How can I make sure that any firewalls (versions of software or hardware) does not block port 443 to access?

  Hi Anna_753,

  Usually, you would receive messages from any program if it is impossible to access the port.

  If you want to check if the port is accessible, then you will need to check the firewall settings.

  Each firewall has its own parameters for ports of the computer.

  Hi all
  
  
  I use Linux and Oracle 10gAs 4 application server.
  
  
  Our Application of Test is access by users using the port 7778, I want just a few users to access my test application (just the admin user) and all other users should not have access to the application, even if they specify the right URL and the port number.
  
  I mean blocking port 7778 to a range of IP address for an IP range

  Oracle HTTP Server is based on Apache. It comes with mod_access. Like mod_access allows you to restrict some IP address ranges, you would be able to do what you need.

  Note that it may be difficult to restrict access to a specific port (you want to use a proxy/firewall to do this), but you can restrict access to some URI. Assume that you use the/foo URI to access your application, something like the below directive would do the trick:

  
     Order allow,deny
     Allow from 192.168.1.0/24
     Allow from 127
  
  

  See https://httpd.apache.org/docs/2.0/mod/mod_access.html for more information or [url https://www.google.nl/search?q=apache+restrict+access+ip+range&aq=1&oq=apache+ip+range+access] Google it.

• Restrict access to external networks by VAPP org model

  In an org, is there a way to restict access to nets external org by VAPP model?  I would have a net external org which is only available for a particular VAPP tempate in the catalog, and then other models do not provide access to the nets outside org. I tried to play with custom roles, but no luck yet.

  Thanks in advance,

  Clark

  As far as I KNOW, I don't think you can handle the microphone at this level.  The Org of external networks are available based on a set of true or false... either available or not available.

• blocked ports affecting http

  On recommendation of Cisco, I have blocked ports TCP 3127-3199 out my interface "inside". Seems that these are commonly used for mydoom ports. Now, when the user's browser uses these ports as source ports they don't have until it exceeds this window. Has anyone seen elsewhere this problem and how do you work around it?

  Roland,

  A MyDoom attack can be launched from the outside (entering your local network) or inside (out to your local network).

  IF YOU WANT TO BLOCK INCOMING OF MYDOOM ATTACKS:

  If this traffic passes through a firewall, then by default, the sessions opened from the outside are blocked unless explicitly allowed entering. If you use a router with ACL, then you must configure an ACL in the INCOMING direction and apply it to the interface from the OUTSIDE as such:

  --------------------------

  For routers:

  access-list 111 tcp refuse any any 3127 3199 Beach

  interface

  IP access-group 111 to

  --------------------------

  In this case, you'll experience the question that you're already because when a web server returns a bunch of session to the client (browser), then the destination ports match the ACL and the router will drop the session. To remedy this, we can apply an IOS Firewall to the external interface of the router. The ACL to block incoming attacks of MyDoom cannot while the router will maintain session state information in its table.

  IF YOU WANT TO BLOCK OUTBOUND MYDOOM ATTACKS:

  Then the ACL must be applied 'in' on the 'inside' interface

  --------------------------

  For the PIX Firewall:

  access-list 111 tcp refuse any any 3127 3199 Beach

  access ip-list 111 allow a whole

  Access-group 111 in the interface inside

  --------------------------

  --------------------------

  For the router:

  access-list 111 tcp refuse any any 3127 3199 Beach

  interface

  IP access-group 111 to

  --------------------------

  This should provide you with enough information to work on your issue.

• Failed to create the external network

  Hi all.

  Well, I have deployed VIO with NSX. I created 2 virtual machines (instances) with 2 internal networks. I created router, plugged on both networks. Tried to ping of vm1 (int_net1) to the virtual machine 2 (int_net2) through router - everything works fine.

  So, the next step was to provide access to Internet of the virtual machines. I try to create the shape of external network Admin-> Control Panel-> network-> network create system:

  Name: extnet1

  Project: MyProject

  Type of network provider: dish (deployment master I chose NSX environment and VLANs separated to outside networks)

  Admin State: checked

  External network: checked

  When I press the button "Create network" an error has occurred: ""Error: failed to create the extnet1 network '. " How can I create external network?

  Thank you all for help. I solved my problem. For the future: you can only use "PortGroup" in Type of network provider. So when I chose PortGroup and set it to the external network 'dvportgroup-XX' have been created.

• External network configuration

  I'm creating an external network for my vCloud assessment.  Only, I intend to have one.  When creating, there is the page 'configure the external network.  You can add lines to the configuration, each apparently being an external subnet that you connected to.  I have a few questions.

  (1) when he says 'Add the subnet' on the wizard, and there ask for the gateway and mask, we're talking the subnet external, correct?

  (2) why can I add several lines?  It seems, in particular, given that my group of underlying port is a VLAN / single subnet, that it would be unwise to add more than a single subnet here.  Under what circumstances I would add more than one row of subnet in this configuration?

  Thank you

  Chad

  So, when you add an external network, you choose a group of ports in vSphere.

  1. you give the information required to configure the NIC cards to be attached to this network, then Yes... all that is on the same physical network real.

  2. some companies want to only allocate specific subsets... maybe the initial set of IP addresses are free, because it is shared with the physical realm.

  Later, maybe you release more... but this isn't a continuous block.  You can then add a second beach.

  It is for the flexibility, nothing more.

• regarding the connection of the virtual machine to the external network

  Hi all

  I'm new to vmware and I have two virtual machines with windows operating system 7. How to connect to the external network?
  can I assign a NATed IP to them?

  If the need to talk about virtual computer internally, you can add all the VM in the same VSS(vswitch 1) at the same port group Network2 VLAN40. for virtual machines on that VLAN can communicate among themselves without problem and configure all virtual machines with IPs in VLAN40. no need for an another vs.

  For internet access, first check with your network administrator, if the VLAN has a routing or this VLAN has access to the DNS server that provide internet or the proxy server for internet access. He will confirm. or you can also check if this virtual machine are able to ping your DNS server or proxy servers. If its power of ping so it has access to this network. Configure the virtual machines that you configure a physical computer for internet access.

  If the VLAN has access to the internet, even that you configure the physical server with connection DNS and proxy for internet access only the configuraiton even here too in the virtual machine.

• social networking sites are blocked by administration how can I accesss them?

  like facebook, orkut, youtube are blocked by the administration to the web Center of my college

  Although this isn't in itself a problem with Mozilla Firefox, you may be able to get access to blocked sites thorugh the use of software (or Mozilla add-on) that will allow you to access a site through a proxy, or by the use of a virtual private network.

  However, please consider reading the terms of use of the network of the University (or similar document).

  It is likely that you are not allowed to use any proxy or virtual private network on the University network. If you do, you may lose your account you are unable to access the network at all!

  So, it's up to you. There are also Web sites that provides a form of proxy service where you simply go to the site and enter the URL of the site you want to access.

  But, as I said: you could be prohibited from using the network if you do not follow the rules, so please be careful and know what you can and can't do using the University network.

• Blocking ports using a virtual Super Hub 2ac (VMDG490) machine

  Hi all

  My first post and hoping that it is in the right place. A few days ago, I received my upgrade to a SHub1 to SHub2ac. After a speed problem. I created 4 blocking rules port for one of my computers successfully, but when I try to create the same blocks for my other computer I get an error of "the port selected range overlaps with an existing rule".

  I gave the rule a new name and have obviously used the ip addresses of the other boxes on the network. It worked well on my old SH1 then why not on an alleged update?

  VM, I called and they had no idea if it was possible and showed me tech, alas, they had no idea that is then reported to me their salary for support Dept. They said it couldn't be done? As a Department tech VM and the pay per help guys were unable to offer advice, other than to block ports through your firewall software. Can be done using Bitdefender, I can see (it's another can of worms in itself).

  Any help or advice of Netgear technicians or other users of the popular home network. As seems a downgrade of the former 1 SuperHub that would allow any amount of blocks of port by using port numbers providing the name of the rule was different and the IP addy has been changed, is there a possibility of a upgrde of firmware to re - enable this option? Or the guys from VM need to RTFM

  Any help is much appreciated in this matter.

  Best regards.

• Communicate with external devices via the USB port on the Playbook

  Hi all

  I've been looking for more information on how to connect to external devices programmatically using the port USB of the Playbook. It seems that the QNX Neutrino system level options do not work, I tried to use system() with some usb since utilities commands (e/s-usb, usb,...) without success. I'm trying to build an application that uses the USB port of the Playbook to connect to a network industry such as devicenet or profi-bus as an example. Anyone know if this is possible? If this is related to another post here, admin please move.

  Change Note: Please answer and the result is pretty much that I had found. I have no contact I can name for RIM, off the top of my head. I think for now, I'll concentrate my efforts for the development of the Playbook.

  This is my speculation, but given the current philosophy of the PlayBook and BB 10 OS, perhaps my speculation is not too bad. Anyway, it is not only a problem of BB, other editors (Apple, Samsung, LG etc) also do not allow this out of the box.

  A few days ago, I played with ultra cheap Chinese junk-Tablet (with resistive screen, buuuu), android 2.3.3 and this unit has a usb port with support for any device usb (mouse, keyboard, 3 g modem) + adapter Ethernet usb custom with 2port usb hub. Man, it was crazy. Maybe these will find its way in BB 10 devices a day.
