Security / Firewalls :: All Ports Blocked Even With DMZ And Firewall Down
Oct 16, 2012
I've been trying to open ports 5800 and 5900 for UltraVNC and checking them with online port checkers, but they are always listed as closed. I've even tried taking town windows firewall, my router firewall (although as soon as I disable and apply, it automatically switches back to enabled again), and also DMZ'ing my router. I wonder if it might have something to do with my new modem, but in the config page for that, the advanced settings are locked out. the modem is an arris TM722G, and the router is a linksys wrt-54G with DDWRT firmware.
I'm running windows 7 x64 and using a static local IP, I want to be able to use DynDNS to connect to UltraVNC.
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 have disabled windows firewall in Windows 2003 server control panel but only few ports are shown opened when i scanned with advanced port scanner why other ports are closed.How to open the closed ports?
I keep getting a pop-up message from my firewall ( Sygate personal -free ) telling me that NT Kernel and system has been blocked. I checked the box to say don't show this message again, it still shows it every time. minutes in between. It freezes my pc and screws up any typing i'm doing at the time. According to the application list it is checked to allow and running.It is not listed in Task Manager.
I was under the impression that those global addresses that we used with NAT were from the outside IP addresses range?Lets say my outside IP address is idk 184.108.40.206 /30 and I only had two usable IPs (since you can't use network and broadcast IPs) so how would I set up NAT for a couple of Inside addresses with a shorting of addresses like this? Idk if that makes sense what I'm trying to say
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 have one Fortigate 200B Fire wall, which is using for wifi internet. i had configured one login page in the fourtigate .The path following below system > config > replacement message > authentication > login page.
it was working earlier. suddenly its not working. when i checked this path, that login page message colum was blanked. when i trying to put the message again its not pasting and am unble to type the message also.
i am using windows vista on my laptop.i was using zone alarm firewall, but switched it to windows firewall.after switching, my internet was cutoff. i can see that i am connected to my network, but cant get to internet.when i run diagnosis on my laptop, it gives me three options:
my Ethernet driver is having hardware issue.
my wireless driver is having hardware issue.
ip protocol binding is having issue. check ipv4 and ipv6 settings.
Recently i had suffering with wireless connection problem, currently my wireless router connected to WAN directly, after that go into firewall and then go thru switch to end user PC, for LAN user there is no issue, but for wireless connected PC it is prompted with limited connectivity problem(DHCP is disable on router), after check with ipconfig /all. it seem likely due to wireless PC cannot get the IP from DHCP server. i am using DLink615 router. i had checked firewall setting there is firewall policy that connected all router ip into company LAN, but i don't think there is DHCP VPN setting up. is there anyway i can go thru firewall and get IP from DHCP server because if i set up DHCP on router, it cannot pass thru and access to LAN.
At my small business (30 employees) we currently don't have a hardware firewall. Should I have one? If so what do you recommend? We are all connected to a Windows Server 2003 domain in one office building.
Each of these has Windows 7, Avast! Anti-VirusToday I was working on a website on PC#1. When I attempted to upload the files via FTP, the connection failed repeatedly. When I went onto PC#2 it worked first time.I also tried to launch World of Warcraft on PC#1, this failed. It worked first time on PC#2.Websites work fine, so port 80 appears to be okay.I have reset my router to factory settings. ipconfig /release /renear /flushdns all made no difference.
I am trying to configure a recently purchased Barracuda Web Filter, After adding the IP address, DNS Server, Default Gateway and the new setings, I am now trying to configure my Corporate Firewall..I do not know what Coporate Firewall the manual is reffering too.
I have seen several cases where ISP's block traffic on both UDP and TCP ports 135-139 even in core firewalls. Port 135 should be Microsoft EPMAP service and ports 136-139 should be NetBIOS services. However, why do ISP's sometimes block traffic on those ports?
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 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 have a customer with active/standby on a pair of 5510's with the CSC modules. They were inquiring about the AIP/ASA, and since this would NOT work in their current setup, would getting a pair of 5510/AIP configured for transparent failover work placed in front fo the existing units? Would I need to have a switch placed between the AIP and CSC ASA's? Or would I setup the ASA's for context based Active/Active failover to interconnect the ASA's to the existing units, but I still see a need for a switch.
As we are unable to control downloads and P2P use in our network, we are thinking to block all ports except 80 and 443 in our router so that they can only browse and use them only for office use. They should also be able to use messengers like skype, YM, MSN and also download any attachments in email.I wonder if we implement this, will it going to work or will there be any problem in accessing normal websites too? I know to control downloads there are many premium hardware and software firewalls out there but we don't want to invest any thing for now.I also know PTP clients can still use 80 and 443 ports to connect but it will need user to change manually port so it's fine with us.
I am stuck in an area that has severly restricted access. I would really like to continue to use my news reader services. However, the guy who set up the nearside router has torrent ports blocked, news group ports blocked, etc.So that people can't bog down the network with downloads.
I have been trying to get port forwarding to work for a week now with no luck. I use Centurylink for Adsl, modem is a zyxel 660r, router wrt54g, running windows 7.I have made my modem a bridge only. I have set my computer to a static ip. I have followed all the instructions for port forwarding on linksys. Still my ports show blocked no matter what check I use on the Internet.
I opened my iTunes program today and noticed a roommate's MP3 files were picked up on my network. I think the name of the program is Rocket Tube MP3. Anyway, I came on here because our computers use a Wi-Fi internet connection and I was wondering how much of my web activity (history, cookies, temporary files, etc) he could see from my laptop if his computer was a desktop downstairs. He's very tech-savvy (a former IT guy) and I don't want him snooping through my personal records.
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?
I have problem with the Lan-to-Lan VPN tunnel.the VPN working fines since 9 months ago without any problems.Suddenly got the problem!,In last two days we faced problem the VPN down.in first time the problem in phase-2.. but after that in phase-1... in latest no data packet received to their side.
I am looking for some resources on what steps would be involved in configuring a Cisco ASA 5500 when obtaining a new ISP. Since our static IP will be changing with the new ISP, just need to know what configurations changes will need to take place. We currently have a working config with DSL, but are switching to cable. We are using a DMZ configuration, and are going to try using ASDM first since that should be easier
