I am trying to figure out how to give computers that connect to my LAN limited access. I have heard that some viruses, though rare, may travel through the network and infect all computers on the network. I want to prevent this. Is there any way to give computers connected to my network strict access to only the internet to prevent viruses or any other harmful attacks?
I'm new to IT, and have been put in charge of managing our servers hile my boss is on vacation.We currently have a Sonicwall Network Security Appliance that handles our Firewall/VPN and have web content filtering set in place.I have a user who belongs to 2 CFS policy groups that we have set up. I've double checked with Active Directory, and he is a member of both groups.
This person SHOULD have access to Job searches/ and Restaurants,but receives a "content blocked" message on his browser.It appears to me that the settings in Sonicwall are correct, as well with AD member groups.
I am trying to connect to a Security-enabled wireless netowork. I have the key. My problem is that I can't seem to figure out how to enter it. When I try to connect I open the "view available networks"window. I see the network name and it shows a strong signal (all 5 green bars).
I've created a hostname & account with [url].... for my vpn setup.It was working fine until 2 days back. owa was accesible and configured MS Exchange on iPhones.
Suddenly it stopped working.The updation of IP from ISP is happening @ chnageip.com site, but when we ping the hostname, it is not resolving to new ip and is not pinging.Our users outside the coporate's internal network is unable to access.
I configured a dynamic vpn(easy vpn) in a cisco isr. But the vpn clients cannot access any of the lan devices. VPN pool is 10.0.0.1- 10.0.0.20 & internal netwrk add is 172.17.x.x. I tried to disable zone based firewall but no resultout[CODE]
I installed Comodo Firewall today, and I couldn't access my Internet from then. I actually liked it's UI and all and want to keep it. The only something that I felt that might be causing the problem is "Use Comodo Secure DNS Server"? Is it likely the reason to be the cause of the problem?
I'm having some problems with a sonicwall pro2040. The problem is this: I can access the sonicwall remotely, and I can ssh into the sonicwall and ping various websites, and get replies, but my connected PCs (Connected by the LAN port) have no internet access. I have never set up a sonicwall before this one, and I feel like there is something I may be missing. Do Sonicwall devices block WAN access by default? Do I need to configure the default route?
I am running a Kodak all in one printer through a Billion 7800n router. The desktop computer running Vista is hard wired and the portable running Windows 7 is wireless to the router. The Printer is hard wired to the Billion router. Where are running Norton 360 on both computers. Everything was running fine until two weeks ago and we get the error that the firewall is stopping access from both computers. I have tried turning off Norton but no effect so I assume it has something to do with the firewall on the Billion 7800n router? Why stop now after several weeks of working fine after setup?
We are a non-profit organization that is heavily reliant on interns that use their own laptops a lot here. My concern is they come in and connect to our wireless network with no supervision or anything else. I am worried they will introduce a virus, trojan, or something to our network. What the best way to keep them from introducing unwanted malware from a thumb drive, virus in email, or something to that effect shy of standing over them while they install and run an antivirus software?
Previously we had no problem with remote users connecting via VPN but recently they can't connect and i've checked the firewall and it shows the errors (see attached jpeg) but I'm not sure what it all means.
I need remote access to certain programs on my home PC but I just cannot get it to work.
When I set the programs port preferences (i.e. port 8087), I can connect with"127.0.0.1:8087" and webcamXP work fine. But when I replace the localhost with my external IP (lets say 220.127.116.11, so that would be "http://18.104.22.168:8087".I tried port forwarding: I have added the port to my NAT in the router's setting so it should be fine, but it is not (numbers are fictual of course):
external port start 8085, external port end 8089, protocol TCP/UDP, internal port start 8085, internal port end 8089, server IP address 192.168.1.215)
I also tried disabling AVG Internet Security 2011's firewall temporarily just to check it it was blocking it, but got the same result.I checked if Windows own firewall was on, but it is off.I cannot find any setting in the router's own configuration screen to disable any build in (router's) firewall (if it has any).
I was wondering how would it be possible for a person to gain access to computer through my router? Or is that even possible? Just a quick rundown, the past few weeks, 2 of my email accounts have been compromised, one was email i had for years, the other was a new random email that i rarely use. In the same week, both these accounts were "hacked" the passwords were changed and i can't get access to them. Same goes for my fb account also compromised. These emails aren't linked to the fb acct neither. I know you might think yeah, i might have clicked on one of these phishing links, but i assure you haven't, i have never entered any of my information on random sites or anything like that. Actually i only really frequent 5 or 6 sites on this certain laptop and i have never downloaded anything on it but songs from iTunes.
I've scanned my computer numerous times, and even went as far as to factory reset it, so i don't know how high the possibility of me having a key logger is.So i guess i'm asking, how would a person be able to have gained access to computer w/o having it in their physical possession? Can i be getting hacked through my wifi connection? What information of mine would someone have to have in order to access my computer and monitor my web activity?
So, I have this router at home a WRT150N. I put in access restrictions so my siblings won't stray onto unwanted pages.I enabled SPI Firewall Protection and what do you know, it worked. The next day though, we didn't have an internet connection.I checked everything with the modem (power cycles, etc.) and then I tried the router. Upon disabling SPI Firewall Protection, the internet connection came back.I tested it yet again, to see if it really was the SPI. Enabled and bam, no internet access again. I made sure to select "Allow" in the Access Restrictions for "Internet access during selected days and hours" making sure also that "Everyday" and "24 Hours" are selected.Now my question is, what do I need to do in order to enable my Access Restrictions without having to lose internet connection via the SPI Firewall?
I was trying few days ago a tutorial of SSH tunneling, but I got an error,"server unexpectedly closed network connection", although I did everything like in the video tutorial and port 433 was not closed.
Is it true that the FCC is investigating the Pogo game site because of poor security? Is Java the cause of this problem?I'm very leery of getting on the Pogo site because I've been told that my computer could get a virus and crash.
I am sharing a network with someone upstairs. They have a wired connection since they are close to the router - I'm using wireless.Routinely get 'No Network Access' or 'Limited Access' or 'No Internet' in the Wireless Network Connections box on my laptop and desktop.The person from who I am renting said it was a range issue. I purchased a range extender that plugs into the wall. This problem still persists, even for my laptop that I can take closer to the source.If I release the IP and renew it I can get a connection back but it usually craps out unexpectedly. This makes me think it's not a range issue, especially with the extender.When I look at an IP config report I notice "DHCP Enabled: No" and "Autoconfig. Enabled: Yes". I am not sure if I am sticking my nose in the right area with this last bit of information.
My father has just bought a new router, because the other one broke. But now the internet on my computer does not work.I connect to the wireless network. After some time it says limited access, but when i then click on the network icon on the bottom right corner and wait some seconds, i get full access again.
I been struggling to repair my internet connection for more than a month now and i haven't found an answer yet. what happens is that every time i re-start my computer or some some time it just disappeared, my net connection. In order to get my connection back there are a lot of different procedures and mix up that i'll have to go through until one of them hit something and return the connection back up. Below are the action so far i have taken:
1. Re-start my computer.
2. Re-start my router
3. Intentionally plug out and plug in the hard wire connection.
4. Change the adapter settings by disabling and enabling it.
5. Do the re-installment of the network through device manager and so on...
i even have tried re-installing my windows 7 but still the problem persist.i have un-install my built in anti-virus esset thinking it may have some how contributed in the disturbance.
Specs: Windows 7 32bit intel core i7 and below is my recent ipconfig
I have a home network that works perfectly fine on all my wireless devices except one of my laptops. I'm getting a yellow triangle with an exclamation mark inside of it in my connections map from "this computer" to the name of my wireless network. I am running windows 7 and I have no idea what is wrong. It used to work fine and just stopped all of a sudden. I'm not sure if my wife or I messed something up.
My windows 7 desktop computer is giving me a "Limited Access" notice when i try to connect to my network. My laptop on the other hand can connect to it easily. I've tried several solutions that I found online, but nothing has worked yet. When I run command prompt ipconfig I get
Microsoft Windows [Version 6.1.7601] Copyright (c) 2009 Microsoft Corporation. All rights reserved. C:UsersJeffrey>ipconfig Windows IP Configuration C:UsersJeffrey>ipconfig /all
I use windows 7.Ever since a couple of days ago, I have not been able to connec tot the internet.It says "not connected" and it says "limited access" next to my router, with 3 bars.Ipv4 Connectivity: Not connectedIpv6 Connectivity: Not connected
From one day to another my internet stopped working, instead of connecting automatically it shows limited access. I tried typing in cmd and IPCONFIG/ALL but that doesnt work either. using non-technical language, I am really bad with computers.
I have a Presario CQ40, and I have been able to connect to my wireless connection until fairly recently. I have not installed any new programs, only updating windows every now and then. Now, I cannot connect to my network (globe broadband) and typing ipconfig showed me no numbers for the default gateway and an ip address starting at 169, which I believe is incorrect. My laptop says that my drivers are up to date.Other laptops can connect just fine on the network, mine is the only exception. If I I have to connect, I have to choose "Other Network", and it always tells me that I have connected unsuccessfully, then showing me I only have limited access.
I am configuring VPN on an 831 rotuer using a dynamic-map configuration. I can connect to the network and I can see phase 1 and 2 complete from the debugs however from what I can tell I can only ping across the VPN. I can't connect to and web services or RDP to any hosts on the local network. Here is a copy of my config.
