• FVS336Gv3 multi-NAT inbound firewall rules does not

  I have about 30 Netgear FVS338 and a few FVS336Gv2 routers in use. I use for firewall and provide multi-NAT between industrial machines and WAN. The configuration was changed on Gv3 models and I can't get an answer behind the firewall or router in the diagnostics page when you use the WAN address.

  In the examples below the WAN is 10.62.

  

  Figure 1. Two different devices with two different configuration options.

  

  Figures 2 and 3. The first is bad - it would only connect from this address. Have I set up another correctly to the NAT WAN to LAN 10.3.110.215 address 10.62.31.55 address?

  Q1: Is Figure 3 configured correctly?

  Q2: Why is it forcing me to create a range of addresses? On the older routers, I had the opportunity to address.

  Q3: Is anyone aware of any problem with this router?

  For anyone having the same problem, the FVS336Gv3 requires the manual addition of each new address WAN-side. He is buried in the menu structure:

  

  Figure 1. Network configuration | WAN settings | WAN configuration. WAN1 - Edit.

  

  Figure 2. Select the secondary addresses.

  

  Figure 3. Add the required WAN addresses.

  Now configure the inbound firewall rules:

  There seems to be a problem with this router about the session timeout. I got them several times on the navigation menu and log on again and renavigate. Idle time-out is set to 90 minutes. I never saw this problem on routers earlier.

  Also, note that the password field now has a limited character set. for example, it does not accept ' $'.

  SBS1 a IP internal of the XX. XX.16.2 on VLAN 1 port 1 on the router

  SBS2 a IP internal of the XX. XX.2.2 on the VLAN 5 port on Router 2

  On the old SA520W, I was able to configure alias IP XX. XX. XX.47 and XX. XX. XX.46 with firewall rules if 47 designated SBS1 and 46 stressed SBS2 to their respective ports.

• searching for NAT/Firewall/static routing tips

  Hello

  I am very new to vCloud network and security. I've read the documentation, but it can be confusing for me. I am attaching a schema to help provide a context for what I'm trying to achieve. Keep in mind that the IP address has been changed for security reasons. Address ranges are not accurate but for the context.

  We have an org routed with a single VM VAPP, directly connected to the VCC-Net. It is a Linux server. We have a vShield edge device. There is no rule of firewall, NAT, static routes configured. Essentially of deployment costs. The owner of the server wants to be able to connect to a Linux repo for updates/etc.

  For testing purposes, I have disabled the vShield firewall to allow all traffic through. from the Linux server, I was able to ping both addresses assigned to the border of vShield (192.168.1.1 and 10.10.16.17) but I couldn't ping 10.10.2.140. This leads me to believe the vShield Edge does not know how to route packets between 192.168.1.0/24 and 10.10.0.0/16.

  I have read and what I'm gathering is that I have to configure NAT and firewall rules to achieve. I googled everything I can, and now I'm just confused. Can someone please give me some advice?

  VShield Edge routing feature is similar to traditional router. By default, it can discover only directly attached networks and deliver packages, in this case 192.168.1.0/24 and 10.10.16.0/16 are direct networks. So if you need reach any other private network, we need to define a static route (it is not supported / configurable in vshield edges of dynamic routing since then). For Linux VM 192.168.1.10/24 join the public network, set a NAT NAT vShield edge rules and enable the appropriate firewall rules.

• quick way to add multiple subnets of Server 2008 firewall rules?

  I set up a firewall in windows server 2008.  I need to add several subnets to a rule for inbound traffic, but it is making me add subnets one at a time.  Is it possible to add several subnets simultaneously?  I tried separating them by commas and add them via the GUI, but he wouldn't take it (he said that specify an address valid).  Also if you have already entered a long list of subnets in a firewall rule is it possible to copy it to another firewall rule?

• RVL200 - SSL VPN and firewall rules

  Forgive my ignorance, but I have been immersed in the configuration of this device RVL200 to allow Remoting SSL VPN to a customer site, sight unseen.  I have the basics of the VPN set up in config, but now move the firewall rules.  We want to block all internal devices to access the Internet, but I don't want to cripple the remote clients that will be borrowed by blocking their return via the SSL VPN traffic.  This leads to my questions:

  (1) a rule of DENIAL of coverage for all traffic OUTBOUND will prevent the primary function of the VPN (to allow the administration away from machines on the local network)?

  (2) if the answer to #1 is 'Yes', what ports/services do I need to open the side LAN?

  (3) building # 2, configuring authorized outbound rules apply only for VPN clients, rather than all the hosts on LAN?

  (4) as the default INCOMING traffic rule is to REFUSE EVERYTHING, do I have to create a rule to allow the VPN tunnel, or guess that in the configuration of the router?

  Here are some other details:

  • The LAN behind the RVL200 is also isolated LAN in a manufacturing environment
  • All hosts on this network have a static IP address on a single subnet.
  • The RVL200 has been configured with a static, public IP on the WAN/INTERNET side.
  • DHCP has been disabled on the RVL200
  • Authentication to the device will use a local database.
  • There is no such thing as no DNS server on the local network
  • The device upstream of the RVL200 is a modem using PPPoE DSL, and the device has been configured for this setting.
  • Several database of local users accounts were created to facilitate the SSL VPN access.

  I worked with other aspects of it for a long time, but limited experience with VPN and the associated firewall rules and zero with this family of aircraft.  Any help will be greatly appreciated.

  aponikikay, there is no port forwarding necessary to the function of the RVL200 SSL - VPN.

  Topic 1. That is not proven. It shouldn't do. The router should automatically make sure that the SSL - VPN router service is functional and accessible.

  Re 2. No transfer necessary. In addition, never before TCP/UDP port 47 or 50 for VPN functions. The TCP 1723 port is used for PPTP. UDP 500 is used for ISAKMP. You usually also to transmit TCP/UDP 4500 port for IPSec encapsulation.

  Let's not port 47. ERM is an IP protocol that is used for virtual private networks. It is a TCP or UDP protocol. GRE has 47 IP protocol number. It has nothing to do with TCP or UDP port 47. TCP and UDP are completely different protocols of free WILL.

  It goes the same for 50: ESP is the payload for IPSec tunnels. ESP is the Protocol IP 50. It has nothing to do with TCP or UDP port 50.

  'Transfer' of the GRE is configured with PPTP passthrough option.

  'Transfer' of the ESP is configured with IPSec passthrough option.

• How to import a TXT file in my list of firewall rules?

  Good then I exported a list of firewall rules in a txt file. I then copied on some firewall rules. Then I saved the file txt and I wonder how I can re - import the txt file. Please note that I don't know of import policy...

  UH I thank you for responding, but apparently you misunderstood what I meant... When I go into windows firewall, there is an option to export the list of rules I want to know is how to re - import this list of rules in because there is no other choice... If so how do I do?

  Since I couldn't find a solution that I found something different that also works. I found a .bat file that you can put in the folder in which you want to block the program and it crashes all the exe files in this folder and all subfolders. You can even choose a fix before custom firewall rule... If any other person having this problem follow the instructions, I provide below:
  
  Instructions (found online modified by me)

  Firewall Windows 7 works fine, but it's not easy to set up with several (very long) programs.
   
  I watched for centuries, trying to find a way to block several files .exe to Windows 7 only once; It seems that the only method was to create my own batch (windows script) file.
  I've added below for anyone to use / modify for their own purposes.
   
   
  Run the commands below (addfwrs.bat) file, will create inbound AND outbound firewall rules that block all .exe files in your chosen folder and subfolders to access internet.
  Very useful.
   
  To use:

  (1) place addfwrs.bat in the folder in which you want to block .exe programs (it crashes all the programs exe in no matter what subfolders if you can place it in a folder without any exe it blocks)
  exe in several subfolders both programs)

  (2) now run CMD as administrator.

  (3) copy the new directory (eg. c:\Programs Files (x 86) \YourProg\) where you put the addfwrs.bat file

  (4) paste it into the directory with "cd" CMD and a space before the directory (example: cd c:\Programs Files (x 86) \YourProg\) and press ENTER.

  (5) now run the batch file by typing: addfwrs.bat "rulename" example: addfwrs "BLOCK_PROGRAM_NAME_HERE".
  (Make sure there is no space in the rulename of the firewall rule, so use underscores as spaces.)

  N.B: It is important that you add a rulename firewall, so that you can identify the rules when adding to the firewall at a later date.

  (6) follow the information on the screen, he will advise you what rules he is creating.

  (7) check the Windows Firewall for new rules listed and you can then delete the addfwrs.bat file where you put it (it is necessary even if you can keep it somewhere for later).

  Quite.  Hope you find it useful, I certainly have!
  Enjoy!

  N.B: The new rules contained in the bosom of your firewall (In/Out rules), change as and when you need.

• [Solved] Research of firewall rule allowing Windows Update

  The problem has been resolved here: https://social.technet.microsoft.com/Forums/en-US/62b9fd5c-10b2-4266-bc15-fcf3e79d20d4/solved-windows-firewall-rule-that-allows-windows-update?forum=w7itpronetworking

  Everything down here is obsolete. (But you can read the true story about the virus of Bagel).

  Someone at - it an outbound Windows Firewall rule allowing Windows Update?

  Details.

  Yesterday, I tried to run Windows Update. The rule of outbound firewall to allow Windows Update to get through, I added was:

  Name: Allow Windows Update
  Group:
  Profile: Public
  Activated: Yes
  Action: allow
  Program: %SystemRoot%\System32\wuapp.exe
  Local address: no
  Remote address: all
  Protocol: all
  The local railway: no
  Remote port: any
  Computers permit: all

  I got 10 updates to install and all 10 failed. The only way that they have all been able to fail is: '% SystemRoot%\System32\wuapp.exe' is the wrong program, OR "wuapp.exe" passes control to another program, I don't know.

  Can anyone help me with this? I'll be forever grateful if you can.

  Note that I had to fall back to the default settings (see 'Background', below) in order to succeed and who has not made me happy.

  Background.

  Despite what you think it means, "outbound connections (green check mark) that do not match a rule are allowed" (which is the default) means only, unless you went to the extreme penalty to create the blocking rules, the firewall is wide open for outbound - connections, essentially, you have no firewall for outbound connections. " That means, 1, if you have a Trojan horse on your computer that is looking to download his main-payload of viruses in your computer (see "A history of real virus", below), or 2, if you have a virus keylogger in your computer who wants to 'phone home' him make his Masters criminal of your online banking user name & password There is absolutely nothing to stop.

  That's why I put my firewall: "(entry not red) outbound connections that do not match a rule are blocked".

  A story real virus.

  A couple of years ago, I visited a well known web site that had been hijacked - was - it cnet? I think so. The site seemed basically OK, but something made me shy away. I've left without clicking anything whatsoever. But the visitor of this site (with active javascript) transferred a Trojan horse in my computer (i.e. "Trojan", below).

  Once it was in my computer, the Trojan horse, then went through my firewall, out - was my firewall zonealarm at this time? I think so - and downloaded Bagel, a key logger to rootkit.

  I had no warning of the firewall as the Trojan horse used a well-known port that was wide open, and I had no antivirus warning because Bagel does not change any existing program. It uses the unallocated file space, patched itself in the initialization string, charged before the mode protected of windows at the next startup and reprogrammed the hardware memory to hide its presence in memory. It took me 2 months to discover Bagel and another 4 months to get rid of him. It was hell. My keyboard and mouse acted constantly upward. I didn't a bank online at this time. If I had, I'm sure that my account would have been cleaned up because that's what Bagel. It's a keylogger monitoring keyboard and browser waits to catch a connection to the Bank.

  Details of Trojan.

  The Trojan horse was a javascript function which ran automatically when the page is loaded. He created a table (similar to a mathematical object matrix) made up of identical over 1 million members of the group. Each Member of the Group was a short string of numbers. As it looped to add table-members, the Trojan horse later (in fractions of a second) overflowed the heap memory management hardware had allocated to my browser. That overflow has partially replaced the next higher segment in memory - which is called a "violation of the limits", and Yes, it is possible, if you position the base register just below the upper part of your segment and then use a large lag. There was a flaw in Windows that could not detect this type of violation of the limits and Bagel is designed to exploit this vulnerability. But the story does not stop there. To take control, the short string of numbers in a table-member of the "wrong"side of this segment limit had to be performed. Now, it of the roll of the dice that viruses are facing, but if the program that was partly crushed is always loaded in memory and running and if it executes the code at the bottom of its segment, then - Voila! -the virus takes control of the timeslice allocated to the program that was partly crushed. In other words, the program that was partly crushed no longer control, the virus is in control. So, what did the do Trojan horse? Completely in the background and without any idea for me, he went to a web site in Ukraine and downloaded the main payload of Bagel. How do I know all this? I looked at the javascript trojan and I disassembled - disassembly is as kind of decoding - the payload of Bagel (the rootkit) that I saved after I found some 6 months later. I still have the payload of Bagel sequestered in a zip in quarantine - in fact, I have a menagerie of dozens of viruses that I use to test antivirus programs.

• SRP527W setting DHCP address and source firewall rules

  In my quest to find a decent ADSL router for VoIP, I found the SRP527W and so far it has been the best performer of a range of boxes from netgear, thomson, and zyxel.  However, I have two questions:

  (1) how to troubleshoot DHCP leases on the LAN address

  (2) how to specify source ip in the firewall rule

  Note:

  I currently have 1 computer on the LAN, VLAN1 interface

  * 192.168.15.100

  and

  2 IP phones on the LAN, VLAN100 interface

  * 192.168.100.100

  * 192.168.100.101

  Address three assigned by the DHCP server lease times with approximately 20 days.

  I would like to repair the three devices DHCP leases, for example if some port forwarding rules can be made with confidence that the rules will not point to another device in the future.

  from PVC0-> 192.168.15.100, Port 3389 for remote desktop

  of PVC0-> 192.168.100.100 ex.port 5881 to int.port 80 for voip phone web-gui

  from PVC0-> 192.168.100.101 ex.port 5882 to int.port 80 for voip phone web-gui

  Ideally, I would like the rules to act like that, limiting myself only to access these ports (from my remote site)

  PVC0 interface where the source is ip 12.34.56.78-> 192.168.15.100, Port 3389 for remote desktop

  PVC0 interface where the source is ip 12.34.56.78-> 192.168.100.100 ex.port 5881 to int.port 80 for voip phone web-gui

  PVC0 interface where the source is ip 12.34.56.78-> 192.168.100.101 ex.port 5882 to int.port 80 for voip phone web-gui

  I hope that makes sense, I appreicate any help you can give.

  Kind regards

  Paul

  Hi Paul,.

  Thank you for using the Cisco support community.

  With regard to two questions:

  1. Yes - it is possible to configure static DHCP assignments.  Use the DHCP Server rule configuration page and click the 'Show DHCP booking' button to assign.

  2. Unfortunately, it is not possible to configure rules to address source for the SRP520 list.  (This is possible on the SRP540 for further reading).

  Kind regards

  Thanks for any help.

  Take a look at the annex in the latest version of the hardening guide - put him to date with some tricks to cross-VC.  You need primary and managers of NSX secondary to communicate for universal synchronization, two managers communicate with the Cluster of universal controller (site 1) and hosts on site 1 and 2 to be able to communicate with the UCC but I don't think you have to your site 2 vCenter/Hosts to communicate with the site 1 NSX Manager if I read it correctly.
