• Use Virtual Cener behind a firewall - high security

  OK, 2 ESX servers are connected behind a firewall. My VC/VIM is a virtual machine on the second ESX host. I installed VC on the virtual machine and was able to connect to it very well. Virtual Infrastructure Client connects to the server VC/VIM. When I try to add one of the ESX servers to my new 'Datacener' I go through the guests of identification and so on. I get to the point where it gives me a list of all the VMS on the server, then click on the "Finish" button and I get an error...

  "Failed to connect to host".

  Keep in mind here that the ESX what IP console is on another segment of the VC/VM.

  Any ideas on what prevents traffic? Appropriate for VIC to work ports are correct. Did I miss a port somewhere?

  Thank you

  How is the routing between the n/w for the n/w VM Console? It is a layer 3 with intravLAN active routing switch or go you through a router? can you run a scan of the virtual machine on the ESX server console IP port and see what all the ports are open. I doubt if the VMware-vpxa agent is installing on the ESX Server.

  You can manually copy the installation script for the VPXagent on the ESX Server and start the installation manually. Check if the connected ESX Server getts now.

• Will be - this safe to use XP behind a firewall after the end of LIFE?

  I have a netbook that I use as an external 1 TB NAS with a hard drive device on my LAN.  I use it also for connection of MagicJack.  I have a firewall in my router and the only thing that that accesses this machine online is updated antivirus and places / receives calls from Magic Jack.  I don't respect the minimum specifications for Windows 7.

  If I keep this machine behind the firewall and prevent web access, it will be safe to stay with XP after the end of life?  MagicJack is a security breach?  My only other option is to switch to a Linux distribution, but I need to configure to run on a Windows network and it seems that you have to do back flips to get the MagicJack to work on Linux.
  Any advice will be appreciated.

  End of the security updates is something much more...

  antivirus support, but again, you are not protected completely...

• It is possible to configure router CISCO1921/K9 from site to Site vpn behind a firewall?

  I am looking to buy CISCO1921/K9 to configure vpn site to site with Amazon VPN. We are behind a firewall. I try to install the new CISCO1921/K9 router according to the scheme of quick text below. My setup work? and what are the ports will it transfer to my firewall?

  INTERNET--> Modem to ISP---> firewall - CISCO1921/K9

  Hi Paul,.

  (192.168.1.0/24) - router (10.1.1.1)-(10.1.1.2) firewall(81.92.61.x/27)---Internet

  The configuration is very simple...

  1. There will be no modifications on the configuration of the VPN router with the exception that the interface of the router (turning to the firewall) will be to have private IP 10.1.1.1

  2. you will need to take a public IP of your range of public (e.g. 81.92.61.2) and will share the same to your remote location which they set up as peers IP to their end.

  3. now you have to configure 2 NAT type on your firewall.

  NAT source:-when your router will initiate VPN

  Before NAT: Destination - Source 10.1.1.1-(homologous remote IP)

  After NAT: Destination - Source 81.92.61.2-(homologous remote IP)

  Destination NAT:-when the remote location will launch the VPN

  before NAT: Destination - Source (remote peer IP)-(81.92.61.2)

  After NAT: Destination - Source (remote peer IP)-(10.1.1.1)

  I hope this is clear :)

• ACS 4.0 behind a firewall

  Hi, we have an ACS 4.0 behind a firewall...

  I want to know what are the ports that must be open beyond 2002 to end of remote connection... ?

  Any idea... ?

  Hello

  ACS is accessible via tcp, 2002, for the initial connection. For subsequent access (moving from one page to the other), it will be used at random ports 2003 or higher (tcp).

  To access this box remotely, you must open a range of ports, for example-> 3500 2002 or 2002-> 5000. PLS, be careful when you specify the range, as too many ports allowed ports COULD present a risk to your ACS server.

  example:

  list of access outside the range of allowed hosts 2002 5000 tcp

  Hope this helps.

• Monitoring of the BONE located behind a firewall

  We must monitor the infrastructure of the operating system on our web servers. These servers are locked for NIS accounts SSH connections, but we can configure a local user with permissions of SSH to a remote agent.

  If we wanted to install a Manager agent on that server instead, is anyway to configure agent manager so that the data is only collected in a survey of the FMS, rather than pushing for the https port 8443 on network internal? Basically, do the transfer information officer Manager of a 'pull' instead of a 'push '.

  Or y at - it a way to get this information to the FMS server internal without opening a two-way port, or not allowing a connection on one direction to be open?

  Or the bottom line here - what is the accepted best practice to create a secure communication information of OS of DMZ servers behind a firewall of SGF?

  Unfortunately, it is currently the only solution.

  In the next major release, we'll add a feature where you can enable reverse-vote for Manager of the specific agent. Those who would be interviewed by the FMS instead of pushing their data and the connection will always be initialized by the FMS.

  This will reverse the direction of the connection and the FMS now needs to open a connection in the demilitarized zone. This will remove the requirement to open an outgoing socket of the DMZ to the host of the FMS.

• DMVPN router behind a firewall

  Hi all

  I would like to know if the router DMVPN works behind a virtual firewall.

  We use ISR routers

  ISR router (spoke)--> virtual firewall--> WAN<-- isr="">

  HIII Jocelyn

  Nice to meet you here also...

  Yes, you are right. all you have to do is open the ports for traffic dmvpn. and also the NAT if the firewall is also performing NAT.

• ESX 3.5 - new esxcfg-firewall rules

  Hi all

  I want to know if it is possigble to make a new rule in the built-in firewall of ESX 3.5 to accept connection only from a specific IP address.

  Example:

  My ESX Server have 6 interface ETH, and I want to make a rule that:

  • on interfece 1 accept the connection only to go to 10.10.10.1 and refuse any other IP who try to connect;

  • on the 5.6 interface accept connection only from 192.168.1.2 and refuse any other IP trying to connect.

  Is this possible?

  Can you help me?

  Thank you very much

  Hello

  Moved to forum security and compliance.

  First, if the interfaces are connected to the service console so it is possible to do what you want but you should know 'iptables' quite well to y to insert the rules what to expect. If it's just a unique IP address, then you can easily place them in a "ban" all using iptables. However, that could prevent vCenter to connect as well. If you really must know which currently connects to ESX and determine how it connects. In my book, I present an iptables script which divides things for you in Chapter 4.   Other options include adding the PPE appropriate to etc/hosts.allow/etc/hosts. Deny, implementation of pam_access.so. What service do you want to "lock"?

  If these interfaces are NOT connected to the service then console, there is no way to use the service console firewall to protect these interfaces. There are indeed not by vSwitch firewall that you want to implement. In this case you are looking to use products like the VMC SLR systems, product of V-security of the gardener or a virtual FW between the external vSwitch and the VMs system.

• How one not acquire Modules for ffx installed behind the firewall?

  I have several installations of firefox on platforms behind several firewalls without internet access. They are maintained to easily access LAN servers, containing notes/logs, etc.. I used several addons, more precisely the all-in-One sidebar for several years. However the current addon page to automatically install the active browser rather than provide a download I can migrate to other browsers. Info in the text below is a MSW platform, but also have many * nix installs that I would like to support.

  Question - how does a download and NOT ask on an active browser, but rather migrate to other facilities in offline mode.

  Hello, when I right click on the button Add to firefox on https://addons.mozilla.org/en-US/firefox/addon/all-in-one-sidebar/ and select Save link under , then as the addon file will be downloaded which could then be transferred to the other pc without internet access.

• Behind a firewall for Internet connections and wireless and inaccessible

  My netbook (XP) was attacked by viruses and therefore the firewall has blocked the internet and wireless connections. I installed the new Norton protection and this shows the machine also Ok. Here's the question - how can I activate the connections again? I realize that he is probabl; is really easy, but I just can not understand. Your help is appreciated. Thank you, Steve.

  You can try to disable the Windows Firewall:

  If you have installed the new Norton protection, I don't think that you need more Windows Firewall.

• SX10 - how to access the web interface behind a firewall

  Howdy

  I have a very simple configuration, router and behind her SX10. I can't access the web interface of the remote unit. Is there a port that I need to activate or something?

  When the device was connected directly to the modem, with the public IP address, I was able to connect to the web interface.

  any suggestions here?

  I enter anything in the field AllowRemote.

  Thanks in advance!

  Web interface can be accessed using HTTP ether (80) or HTTPS (443).  To you how you want to deploy, but you can use NAT on the router, port forwarding, or even put the SX10 in DMZ on the router.

• Device behind a Firewall other, ASA VPN

  I have a client who wants to put their VPN / behind the ASA ASA main connected to the Internet.  Both devices have an inside leg for the internal network, but the ASA VPN connects directly to the Internet ASA.

  Topology:

  Outisde FW: Internet transfer Procedure > ASA/FW > leg DMZ to ASA/VPN

  ASA VPN: Outside the L3 Interface interface DMZ of ASA/FW link

  On the outside NAT FW I would be the external address of the VPN / ASA outside the public IP address is available and I have a rule that allows all IP from outside to outside the private IP VPN.  Inside = 192.168.254.1 outside = public IP address.

  Configured on the VPN / ASA, ASA standard SSL Remote Access.

  When I hit the NAT public IP address, nothing happens.  I've run packet - trace on the FW outside, and everything seems good.

  Someone at - it a sampling plan / config for a similar topology?     Internet > ASA/FW > dmz-leg > ASA/VPN

  Thanks in advance,
  Bob

  Can share you your NAT and routing configuration? Of these two ASAs

• ESX host has a virtual machine that must be behind a physical firewall

  We have several hosts of ESXi.  Some are standard ver3.5, while others are standard ver4.1.  All guests of stand alone.

  A host ESX ver3.5 has 6 virtual computers assigned to the network port of the single on a vSwitch stand-alone virtual computer group.   This switch has 3 uplinks.

  One of the virtual machines must place the physical while the rest remains in front of the firewall as well as the ESX host firewall.   I am told that this can be done by assigning one of of the uplinks to a subnet that is behind the firewall.  And this is the best way to manage it.   My question is: is it possible?   My experience limited with physical firewall and what knowledge I have of VI3, we would need to create a separate vSwitch to do this and assign the VM to these switches... and that's if the uplink can be assigned to a physical switch that connects to another switch behind the firewall (I think).

  Something doesn't seem quite in here... I'm not sure it will work.

  Sounds good to me. If it is a separate physical switch to connect, then you will need an additional vSwitch. If it's just a separate VLAN you could - depending on your current configuration (VST) - just create a new port with the appropriate VLAN ID configured Group.

• Cannot configure the firewall using vSphere client (access to ESX 4i)

  I can't acess the firewall by using the client vSphere connection to a host of 4i ESX.  I select the host & gt; configuration & gt; Safety profile & gt; and it flashes firewall briefly, but then watch as services (two) (VMware vCenter Agent (arrested) and NTP daemon (started).

  Clues?  I restarted services (and the host itself).

  ESXi should be behind a firewall because there is no firewall integrated its own.

• several customers behind peripheral pptp firewall/nat at vpn3015

  Hello

  I'll try the following:

  Win2K PC behind a modem to Lan 3com (making the nat) try to make a pptp connection to our vpn concentrator. A customer will always be to establish contact, but future clients will fail. The vpn concentrator has the following message is displayed:

  815 10/21/2002 19:55:49.870 SEV = 4 RPT PPTP/33 = 20 x.x.x.x

  Tunnel PPTP for peer x.x.x.x refused - already put in place

  We also tried another site that is behind a firewall, and the same thing happens.

  Such an arrangement is possible support 3015 vpn concentrator using?

  Will this work if I use the client ipsec (cisco or win2k)?

  Thank you

  Norman

  I suspect that you really have an environment PAT (Port Address Translation, or more within a single address on the outside). If this is the case, PPTP will fail because it uses GRE, which is IP (Protocol 47, I think) as well as TCP port 1723. Since GRE is not a port associated with this such as TCP or UDP, most implementations fail completely or, as in your case, allow only one simultaneous connection.

  If you go to IPSec by using the Cisco Unity client, you can work around this by implementing IPSec over UDP, which will transport over UDP, thus allowing the ports to associate with different connections.
