Restrict network guest/BYOD

We received a preconfigured router, but it was not configured correctly. Initially, our guest and VLAN BYOD had no access to the internet. I added

access-list 130 permit ip 192.168.2.0 0.0.0.255 any
access-list 130 allow ip 192.168.3.0 0.0.0.255 any

And as expected, there are now internet access, but there is also access to our internal network. I need to create a separate roadmap or set up access groups? Where can I I only allow traffic to 0.0.0.0 instead of somehow? Or I need to create deny rules?

Port forwarding does not work, but I'm not sure this is the right place to ask about it.

Hello

You must use the access list 130 to control traffic between your internal network and the network BYOD. Create another list of nat access.

Thank you

    I just upgraded my iPad Mini iOS 10.0.1. He is now running Safari 10. I tried to visit an internal/private IP on port 4190 using HTTP. I get an error that says:

    Safari cannot open the page.

    The error was: "not allowed to use the restricted network port.

    On iOS 9.3 using Safari 9, the same URL opens fine without this error.

    Do not know what has changed since iOS to iOS 10.0.1, 9.3 but I'm unable to visit a web site that I have visited before.

    I know that WebKit maintains a list of ports that you cannot go (e.g. 6666), 4190 is not a restricted port AFAIK. I don't know why I get this error message.

    It seems I was looking at the wrong source code.

  • Network Guest traffic is routed to the external network (LAN)

    I think this is a basic question, but I couldn't find a clear answer in blogs, so thank you for your patience.

    We want to make sure that all Guest network traffic is routed through our physical network.  Configuration: VMs are contained in several groups of ports that are 'under' a unique vSwitch.  The vSwitch is associated with a physical NETWORK adapter, and each group of Port represents a different subnet.

    It's all each guest traffic goes through the physical NIC to our physical network (routers, etc.), including traffic from customers who are in the same group of Port/subnet?

    Thanks in advance for your help.

    Steve

    VSwitches function as physical switches. .so if 2 virtual computers are ion the same ESX host and in the same subnet, there is no need of any traffic go via your physical network.

    Of course, if the virtual machines are on different ESX hosts, traffic must go physical interrrupteurs to reach the destination addresses.

  • HP PhotoSmart restricted 6525 in the wireless network connection

    Hello

    I need to connect my HP PhotoSmart 6525 to a wireless network in my college dorm room.  IT supports the University has published the requirements for the connection to the restricted network and attention that many printers cannot. I looked on the HP website to see if my printer supports the protocols required, but information HP provides on the website is not detailed enough to tell.  I hope that someone on the forum can help me.

    Here are the requirements of universities to connect to the restricted network:

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

    • A device with a Wi - Fi adapter capable of 802.11 g, 802. 11A or 802.11n

      Note: 802. 11 b-only devices are not supported

    • To enable DHCP (Dynamic Host Configuration Protocol) to obtain IP configuration information

    • Operating system and drivers that support:
      • authentication of 802. 1 x (also commonly referred to as WPA-Enterprise or WPA2-Enterprise)
      • WPA2-AES (preferred) or WPA-TKIP
      • EAP-PEAPv0 (external auth) / MSCHAPv2 (internal auth) or EAP-TTLS (external auth) / MSCHAPv2 (inner auth)

    All connections to the campus network, no matter what either wired or wireless, must also bear the following (which are installed and enabled by default on modern operating systems):

    • IPv4 (Internet Protocol version 4)
    • TCP (Transmission Control Protocol)
    • UDP (User Datagram Protocol)
    • ICMP (Internet Control Message Protocol)

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

    Does anyone know if the HP PhotoSmart 6525 meets these requirements?  For example, he says "PEAPv0(outer auth)/EAP-MSCHAPv2 (internal auth)" or "EAP-TTLS(outer auth)/MSCHAPv2(inner auth)?

    Thanks in advance,

    Paul2

    "I could check on the web site of www.wi-fi.org HP Photosmart 6520 series is approved for"WPA-Personal"and"WPA2-Personal"and _not_ certified for" ' WPA-Enterprise and WPA2-Enterprise.  The Enterprise versions require the device to authenticate with a username and password, while the personal versions are not.  I also talked to the school, IT supports and independently, they have said that the problem with the help of authentication printers more is that you can not provide a user name and password.  Given that I could check with two sources independently, according to me, the definitive answer is that I can't use the printer with wireless network from business school.

  • Linux Guest network on the Windows host OS

    Hey

    I would like to give my comments dare a dedicated IP address. They are configured in the Windows adapter (Server 2003) and are operational, in addition, the bridge is configured correctly - and when I configure NAT in the network of the client (using DHCP), everything works fine. Could you tell me the settings of network guest OS for the device (eth0) Please?

    I mean, definition of the IP address of one of them that is configured in the network adapter on Windows, using the same gateway, and the same name servers does not work. It is said that the interface is in place but does not work.

    Advice would be greatly appreciated, thanks in advance!

    You have not need to assign the IPs on side Windows if you use bridged networking infact, by doing so, you are going to have caused a conflict of IP address with the Linux VM.

    Let the VMNet adapters to their default values. Select mode bridged for the prompt, then assign an IP address for eth0, which should be.

  • ISE-guest user account multiple connections

    Hello

    How do ISE I only allow a connection to the guest both user account.    the real problem I have is when I give a username invited to someone, it can circulate this userid with others and multiple unauthorized guests use this unique user id to connect to the portal comments

    In any case restrict?

    Limiting the guests at a Session active network

    You can restrict the guests to have a single device connected to the network at a time. When clients try to connect with another device, the device is automatically disconnected from the network.

    It is a global setting that affects all the portals comments.

    Step 1 choose Administration > management Web portal > settings > comments > political portal.

    Step 2 check the only guest session authorized by user option.

    Step 3 click Save.

  • Comments of print with extreme network and printer HP Envy 4520

    Project night and I have people coming. My comments and personal networks are set up. I have an extreme Airpot and a range of printers HP 4520. Is there a way that my guests and I can print from here. Other then to move networks back on my printer? I tell myself that I'm asking here before I ask HP. I seem to get better answers here. Thanks for any idea!

    Users connected to the network 'Guest' cannot 'see' all devices in the 'hand' or 'private '.  Only "see you" each other and connect to the Internet.

    Same thing for users on the hand, or a private network.

    If you want a user on the network to be able to print, then you will need to install a printer wireless network reviews.

    If users on the main network and the guest network printing, then you need a printer for each network.

    A Dingo workaround solution would be to ask him to send you an email with an attachment that you can print and give back their.

  • How can I block a unknown user to access my home network on windows 7?

    I discovered an access device to my network which does not belong there. I can't access, so I can't really do anything to the extent of the see who it is. I thought it was just someone leeches off my wifi hotspot, but when I turned off wifi, they log. When I try to access this unknown, my computer tells me that, basically, the unit is not there. How can I put an end to unwanted access to my network guests? I think it would be not possible, given that the network requires a password to gain access. I did not the password to anyone except those authorized, and yet, here I have a device owned by a person named "Griff" connected to my network.

    I have already been burned by leechers unauthorized hiding behind my IP and downloading illegal or pirated content. I don't want this headache yet. How can I stop this?

    Here's my view of what has been published. Disabling the SSID broadcast will stop that casual leechers. #2 will not accomplish all that it's someone who connect to your network. #3 is a given... you need to change your password and #4 is probably your best choice, but I would like to change it, so that only the mac addresses you specify can connect to the network.

  • What is the network access Protection Agent and when should it be on?

    It seems to be disabled by default in the Action Center Security Section.  What does if it is turned on?

    Hello

    The network access Protection agent service collects and manages health information for client computers on a network. The information collected by the NAP agent are used to ensure that the client computer has the required software and settings. If a client computer is not compatible with the health policy, it can be equipped with restricted network access until their configuration is updated. Depending on the configuration of health policies, client computers may be automatically refreshed allowing users to quickly regain full network access without having to manually update the computer. By default, the startup type of Network Access Protection (NAP), agent service is manual under services.msc.

  • Should I have the Network Access Protection Agent Service to start automatically on Windows 8?

    Hello!

    While I was looking for a completely different setting in Control Panel in Windows 8, I came across the center of the Action settings and noticed that the Agent of network access Protection service is not running. I open the computer management snap-in and noticed that the service is configured by default must be started manually. I looked for more information on the internet but I wasn't able to find a detailed explanation about his goal for a personal computer. The only explanation I found applied only to Windows Server.

    Is it really necessary to configure this service to start automatically on a home network, or can it be just left set to start manually? What is its use on Windows 8? Is this just in case the computer needs to access a network of business domain?

    I am running Windows 8 Pro 64-bit edition on an Acer Aspire 5552-5898 connected most of the time in my network domestic, although usually I connect to public networks. My computer is not configured to connect to a domain on a corporate network, not even using VPN. When I access my e-mail from this computer company account, I first need to authenticate with a code provided by RSA device before I can connect to Outlook (OWA).

    Re: Flow very slow network-> Guest host, but no comments <-home


    So far, none of the solutions worked. I turned off "Large Send Offload" on each adapter that I could find on the host and the guest. Nothing. Restore these settings in any combination with other out does not work either. I edited the .vmx file and replace by vmxnet3 occurrences, and that no longer works. So far nothing I've tried has worked. I disabled all firewall and antivirus. Still nothing. When I run Guest OS Windows Network Diagnostics, I get the "your modem broadband has connectivity problems." However, I know that this is not the case. I also used the "Virtual Network Editor" to force the bridge connection to select the correct network card (in my case, it's the Intel Centrino Wireless - N 1030 wireless card), but still no luck. Any help would be much appreciated.

I'll probably create another topic more precisely around Bitdefender firewall configuration to allow traffic network through Bridged from VMware.
