How to block internet connection for a period of time?

Hey guys is there a way to block internet connection via a lan connection for a period of time? A program that when my pc is boot up it run secretly and at the time schedule it block the internet connection with no pop up. When i not at home some person

Hi,
You could create a schedule task to achieve this.
The detailed solution please refer to this thread:

Blocking internet access in a virtual windows xp box

Is there a way to block internet access when I have a virtual windows xp box within Windows 7?
The reason, is I just want to run one application and restrict internet access as I some users are restricted from the internet.
Thanks
John

Hi, Juke.
I'm afraid I'm a dummy, and don't know how to do this. I'm sure as April 8 approaches, a lot of people with important DOS or XP apps will be wanting to insulate their XP VM from potential hacking while still running programs locally.
Thanks -- Dave K.

Block internet to certain apps?

I am trying to block internet access to certain 3rd party (non-Apple) applications that I run in Mac OS X. I'd rather not say why I need to do this, but my computer should basically just stop all attempts at an internet connection by these applications (it should act as though there is no internet connection).
On Windows, I would just find the port the applications are trying to use and block the ports with my firewall. How do I do this on my Mac?
BTW, I'm a recent switcher, but am computer and IP literate.
Other info: I switch between Wifi and a Wired ethernet connection. Please ask for any other details you need.

Firefox either closes suddenly when I click on the address bar after startup or it hangs and also blocks internet explorer from loading

On my Windows XP sp3 system the current the last two releases of Firefox both exhibit the same behavior. When I launch Firefox it will either shutdown within seconds with no crash reporter or other error logged or it will hang completely and indefinitely. When it hangs it also blocks internet explorer 8 from loading. I have tried and followed all the steps in the crashing FAQ including safe mode, uninstalls, re-installs, profile deletes (even the profile dialog closed suddenly). I use Norton Internet Security version 18.6.0.29. A full virus scan does not find any problems. I have disabled all toolbars, plugins and addons and the problem persists. Google Chrome, Internet Explorer and Opera all work fine. Only occasionally does Firefox load and keep running. It's as if it is failing on some check at startup and either crashes or hangs most of the time.

That is a Flash Player that plays an MP3 file.

How to block internet to one of my machines

I have a very old windows 95 machine on my network. I am trying to figure out how to block internet usage to this machine but maintain the network. I use PC MacLan on that machine and it works fine. It is just that there is NO virus protection on this machine which means it is open all the time unless I unplug the ethernet cable.
Can anyone give me any suggestions? I have a router and dsl. Was hoping I could make some kind of setting in the OS pref panel.

Except I have to give that machine a fixed IP, correct?
Nope, DHCP will be fine, as long as the Router can prevent Internet for that one.
I think you can block Internet Access right on the PC too, by Not giving rights to use any Browser or eMail program, see if this helps...

Safari pop up blocking Internet use, Safari pop up blocking Internet use

A pop up in safari has blocked Internet use and shut down options. I can shut down but it reappears when I open up safari

Hi Crittervan,
As of now NO, there is not a way to block some popup windows and not others.
You have to just uncheck block popup blockers when you may need them.
You can send Feedback requesting this feature on future os.

WRT1900AC does not block internet access in Parental Control

Hi,My router does not block internet access on my other PC. I tryed "Always" tryed specific addresses, tryed IP addresses and everything tech support suggested. I even replaced the router at their advise. Nothing helped. I realize that the problem is not the router but probably my home network configuration, but I can't figure out what is it. To my defence, so couldn't they Does anybody have or had such a problem?Thank you

WRT54Gv3 Looses/Blocks Internet Access

After installing version 4.21.1 of the Linksys frimware on my router WRT54Gv3 it will loose and/or block access to the internet. It will do it at random times usually weeks apart. All the lights on the router look normal, my modem still shows a connection to the router. My computers will connect to the router wired or wireless and I can also login to the config page of the router. Visually everything looks fine. Power cycling the modem and router does not fix the problem. I have to perform a factory reset on the router before it will work again. Is anyone having this problem with v4 or below of the WRT54G router after installing 4.21.1 of the linksys firmware? My friends router does the same thing and he has v4. I have v3.
Thanks

Well my router has always had the default IP address.
I also noticed that when the internet is being block that i can use the diagnostic tab and get a response using ping and perform trace routes.
I can also release and renew my IP info from Comcast's DHCP Server.
I've never had a signal issue with the router. I'm always able to connect to it using a wireless or wired connection. I connect successfully to the router it's that it blocks access to the internet to all the connected computers.
I'm at a loss and so it seems with Linksys tech support. I had a chat with them and they made me do a factory reset then update the firmware and then perform a factory reset again. They felt that the firmware may have been somehow damaged when I previously updated the router. I feel like my router will start blocking internet access again by the end of the month. If not I'll let you know if resetting, flashing, and resetting thing worked.

Blocking Internet to few users alone

Hi

Assuming you have an ACL to block your /24, add an ACE to allow access to known email server IPs or open up the ports used by pop (usually port 25), or do both.

Airport Extreme blocking internet on phone and ipad but not imac

I got a new TIme Warner cable modem yesterday and since then my Airport Extreme does not work properly.
Time Warner see it at their end but told me that it blocks the signal from the modem to the computer.
However after much fiddling around with it I managed to get it working again with my computer.
So now I have wireless internet on my computer, but although the router is recognized by my ipad and my phone it won't connect them to the internet.
I restarted all devices multiple times and I even reset the entire network.
What is going on?
Also, I'm using an old Airport Extreme (the round one) that Apple no longer supports, however I also have a newer square version, but my computer doesn't recognize it at all. What gives?

I have had the same issue for the past few weeks and finaly it is resolved. I had the regular modem from Timewarner and it was working perfectly with my AEBS for the past 2 years. No issues at all. Out of nowhere 3 weeks ago my mo AEBS started getting the 169.x.x.x ip address therefore not communicating with the modem. Cutting the story short, I had Timewarner's Tier 1, 2 and 3 involved. 3 different techs and their suppervisors visited my house pointing finger at the Apple and I contaced Apple and got no resolutions either. The AEBS at somepoit would connect to the internet and then stop communicatiog due to invalid ip address. I decided to change my modem to a more advanced modem ARRIS TG852 (Telephony modem with wireless) from TimeWarner. That did not solve the issue either. I also tried the solution Tesserax offered above but unfortunatly it did notwork for me. as of one houre ago I resolved the problem and would like to share it with you.
Standard Timewarner modem:
1. Call Timewarner and have the tech support configure your modem remotely into a Bridge Mode. (yes that simple)
2. Factory reset you AEBS and go through the setup.
ARRIS modems or any other wifi capable modems/routers:
1. Call Timewarner and have the tech support configure your WiFi modem remotely into a Bridge Mode. (yes that simple) Sadly enough non of the techs offered this to me or was even aware that this will resolve the issue. Now they know. LOL
OR
1. Get to your routers setup page. for ARRIS go to http://192.168.100.1
2. Login as admin and use default password "password" to login.
3. go to Firewall tab and disable the firewall (your AEBS will have its own firewall)
4. to to Wireless tab and Disable wireless (uncheck the box)
5. go to LAN tab and under the NAT title which is close to the bottom of the page select "Bridge"
This option will reset your modem. Give it a few minutes for your modem to reestablish connections with its center and come back to life.
Now your Timewarner WiFi modem is turned into a dumb modem (bridge mode) and your AEBS will work like a charm.
6. Factory reset you AEBS and go through the setup.
It only took me 3 weeks to figure this out by trying any possible combination of settings and resetings and reconfiguration you can imagin. I have recreated this issue and resolved it following these steps and it worked for me. I hope it works for anyone else that may be facing the same challenge.
Cheers

Block Internet Provider

I have two internet connection at my home. Qwest and Ptera. I have Dish Network with the sling box that allows me to watch live TV and recorded content on a PC or Smart Phone.
I first connected my Dish DVR to my Qwest DSL for testing - I downloaded the Dish Network AP on to my Smart Phone and watched live TV on it.
Great it works.
So I then connected my Dish DVR to Ptera (which has the 15 times faster uploads) and then went to work (also a Ptera connection) and watched live TV with Dishonline on my PC. But when I tried to watch it on my phone the app said that my DVR was not connected to the internet. Woa.
So when I went back home I ran diagnostics on my DVR and it said it was properly connected to the internet. Tried the app again and it still said my DVR was not connected.
I unplugged my DVR from Ptera and plugged into my Qwest connection and verified the DVR internet connection.
I then tried the App again and it worked fine.
Plugged my DVR back into Ptera and again the app said my DVR was connected to the internet.
So any time I try to stream from my Ptera connection to Verizon it is blocked.
I would like to know why and how to get it fixed.
My Ptera connection is far better to use for streaming data from.

You probably can not do so if an internet provider blocks it.
There may be alternatives see [/questions/940600]

Firewall blocks internet sharing

Hi all,
I know this has been covered before but I've never seen a solution that works for me. Maybe someone has time to talk me through it.
All I need to do is configure the OS X firewall so that internet sharing via ethernet isn't blocked by the firewall. Can I do this via the terminal? Which ports do I need to open? I need this to work so I can distribute builds across Xcode installations but I think internet sharing is all that is required for it to work.
Thanks,
Stephen

In the Sharing pane of System Preferences, click the Advanced button under the Firewall tab, enable firewall logging, and then try using those services on the other computer. When done, check the firewall log and look for the number after the : in the logged entries; this is a port number. Knowing the IP address of the other machine will help determine which entries were produced by it as opposed to ones which came from the Internet; this is visible in the Network pane of System Preferences.
