Can't Access Secure Websites Nothing Changed?
May 25, 2012
I work for a small company where we have a simple network that runs from one router and I believe has a switch. We all have access to the network wirelessly or with cable.The internet was running ok up until yesterday when I came in to do some online banking and thought the site was down. However, turned out it was just me that was having trouble. I coudn't access secure sites like online banking or facebook for example. Now I was using the cable at the time and this wasn't working. When I tried wirelessly it would work... this confused me but not as much as when I found out that others in the office could use the cable and even more, there are 2 others who cannot connect to secure sites with cable or wireless.I was wondering what could have changed over night as this is what seemed to happen. Is it our ISP? (prob not as others are ok) so I'm thinking there must be some kind of setup issue in our configuration. I believe we are all using dynamic IP addresses but I'm not sure if thats even relevant

I am using Comcast as an ISP and have a standalone Arris modem. I, obviously, have a DIR-655 router REV B with a firmware revision on 2.00NA. I have already turned off packet shaping and QOS. Also, I have set the firewall settings to Endpoint Independent for both TCP and UDP, and assigned static IP addresses to my computers. The problem I am having is that whenever I go to any secure websites, i.e. anything that starts with https, it takes an extraordinary long time to log in and to navigate to any webpages therein. I also cannot upload photos to a website and when I try the Speed-test.net website the download speed is OK but the upload test errors out, it doesn't connect.

How can we host 300+ secure (https) websites using a couple of public IP's on an ASA5520 with AIP SSM-20 and with as few certificates as possible?
Summary of set-up:
We currently host a number of websites using an ASA5520 and use host headers, so have 6 servers with around 40 hosted URL's. The number of websites is due to double very soon and we will need to use more of our public IP's. We can see that we will will run out of public IP's very soon especially as there is a project in the pipeline that has a likely requirement to host an additional 200+ websites.
Each of these websites are required to use https and therefore each must have a certificate which will be very expensive. PCI DSS (payment card industry data security standard) is causing us issues because we had hoped to post the certificates on the firewall (one for each physical server) and then run the data UN-encrypted from the firewall to the relevant web servers, so that we could use one certificate for lots of websites and therefore reduce our certificate costs, however is not best practice to do this due to the data being unencrypted within the firewall and on the DMZ network and therefore potentially open to compromise. I doubt that we could install 200+ certificates on a 5520 and then re-encrypt the data to the web servers especially seeing as we also have an IPS card that is already running at around 70-80% util due to the performance overhead.
BTW - We also have an in-line Breach WAF which will be required to inspect the packets (certificates to be installed on the WAF to allow this).

DIR655 with 1.33NA firmware. I'm trying to determine how to block access to the internet for a specific LAN computer when the user knows how to change a MAC address. I don't want to turn MAC control on and grant only to listed computers - the list doesn't accommodate enough MAC addresses, and the client has wireless and wired since it's a laptop. I also don't want to set static IPs on all of the devices since some cannot accommodate that feature.I'm thinking that reserving an IP address isn't ultimately the solution either, since assigning the IP isn't going to work if the MAC changes. how to use access control under these circumstances?

With basic "Wizard" setup I got DHCP and port 80 for the camera. It was working just fine with MyDLink and locally with DLink-ViewCam software and some local test web pages. However, we have a wireless printer on that router which also uses port 80, so when it was installed we set up a "port forward" for port 80 traffic to it for administration from other subnets. How MyDLink website is able to tunnel through our hardware firewall and the wireless routers firewall to communicate with the camera is not clear to me (perhaps someone can send me a link to an explanation??), but it works...Thus, to allow access to the camera from other subents, I wanted to change the camera's port from 80 to another, say 8181 and set up the appropriate "port forwarding for TCP and UDP. All of the steps below were from a PC within the camera's subnet/router so port forwarding is not an issue

I have a Linksys E3000, have had it successfully connected for three months now. Recently I attempted to connect my xbox 360 to the wifi and had issues connecting it. So I called ATT to obtain the PPPoE username and password, which they reluctantly gave me. Entered that into the xbox and still unable to connect, so I have given up on the xbox for the time being, I'll post that issue in a different forum. Where my issue is now is since contacting ATT the WPA2 password I set up for the router no longer works. I cannot access the router setup page, and I cannot add any new wifi devices. Although, all of the previously connected wifi devices are still connected to the router despite this issue. Is there anyway to make the old password work, or do I have to reset the router and start from scratch, and God forbid contact ATT again?

I've just been testing QOS on 3560 with version 15.0(1) and it seems the the default qos trust behavior on access ports has changed. By default the trust state of a port is not to trust anything, however rather than rewriting the DSCP value of the incoming packets and settign it to 0 the switch now seems to leave the DSCP value unchanged.
SW04-C3560(config)# do sh mls qos int g0/2
GigabitEthernet0/2
trust state: not trusted
trust mode: not trusted
trust enabled flag: ena

Getting a message along the lines of: can't access this website when accessing certain websites such as the BBC and my university's intranet as well as random websites, also I can't access things like the online content on games such as far cry 3 or saints row 3.I've tried rebooting the router, I've tried the command prompt tracert, I've tried getting on other browsers with no avail and I've tried the other computers in my house and they've been getting on fine, tried full antivirus and malware scans and I've tried checking my firewall settings.

I see the router and the modem are working just fine as usual and even the guy from comcast says there is nothing wrong with the internet connection itself.The problems I am having right now are
- I can only access to Facebook, Spotify, but nothing else.
- It sometimes randomly comes back and everything works but then it only lasts for a few minutes-hours and it goes off and won't work again. I've tried resetting the modem, router, and I even tried creating a new network but nothing worked out so far.I currently own a mac and a windows 7 laptop.

I have an XP machine that i am not access websites from. the machine is hardwired into a router, the other computers connected to the router(wifi) are able to get access websites without issue.here are the steps i have taken and the things i know so far.im pulling a valid ip address, with correct dns/gateway all that good stuff
able to ping other machines on the network, pings the router, and able to ping google.com(so i know there is connection between me and the internet, and that dns is working)
installed firefox to see if it was a problem with IE, no go.took a look at the active process and looked up anything that wasnt familiar, that seems to be good.virus scan with avast came up clean, avast is able to connect to its database and pull the most current virus defs.
there isnt a firewall, the only security measures on the computer is avast.

Over the past few months I've noticed that, although my USB adapter picks up a good signal from the router (never less than 65 - 70% signal strength) and stays connected to it I am at times unable to access any websites. It started off happening once or twice a week and could happen for about 5 - 10 minutes at a time but now happens several times a day and can stop me accessing the web even though the USB adapter says that it is still picking up the signal from the router. After a period of time it will just start working again, I don't have to restart the router or anything.I've tried changing the channel to a few different ones after using a utility to see what my neighbours were using but this hasn't made a difference. I'm using a Netgear RangeMax Dual Band Wireless-N USB Adapter. It has the N technology so should work pretty well.The current firmware version is 1.00VG dated 5th May 2009. In the router settings it allows you to search for an update for the firmware however it told me that my current version is the most up to date.

I have a PIX 501 with 6.2 FW. The firewall inside network is connected to a Windows server (Mailserver). I can get access to most websites on all clients as well as on the server. However, there are some particular websites, such as facebook.com that the server and all but one client cannot access. I get a "cannot display the webpage" in internet explorer.
I have disabled the Windows firewall and AV. I have also scanned for any malware and no malware was found.
I found on the forums a "fixup protocol dns" solution, but my PIX version does not support it.
Below is my config:
PIX Version 6.2(2)
nameif ethernet0 outside security0
nameif ethernet1 inside security100

I've been having a really annoying issue with my computer not connecting to the internet wirelessly I start the computer, and a connection is there via my router for about 30secs-2mins. After this, I can't access any websites. The full five bars remain white and the router is still seen by the computer, but there is a small yellow exclamation sign in front of it, and a mouse-over says "no internet access". I can still access when wired to the router through a cable, so I thought it might be an issue with my wireless card, but wireless USB adapters don't make a difference, even when I've disabled the wireless card. My drivers are all up to date, and I've even tried a full reformat and reinstall of Windows 7, to no avail. Other devices (a couple of computers and phones) can connect to the router fine, and the network even tried a new router, with no success. I have experienced this immediately after the reinstall, before either firewall (I use ZoneAlarm Free) or AV (I use Avast! Free) were installed, and I'm completely stuck.

When I moved in to my roommate's house, her computer was already set up with an unsecured wireless network listed as Open and Disabled requiring no password. All of a sudden, it now has a lock next to the name in the list of wireless networks and asks me for a password when I try to connect. My roommate knows NOTHING about computers and has no idea how it happened. She has an Arris modem, Windows 7. I tried typing in the common IP address for Arris and I did get to a screen giving a lot of info about the system. But there was no where to log in or change any passwords.

Iv tried about everything you can find when you google things about not being able to access a particular website but none work checking out all security settings, deleting all cache, disabling security, checking date and time, flushdns, use opendns, try other devices (not one device in my household can get to https pages on this one site), making sure root certificates are updated, bypassing router, unplugging internet and router to ''reset'', trouble shooting with isp, website, ssl issuer, other wildblue users, other website users, other tech forum, checking for virus and malware and I'm sure there's more that I can't recall at the moment. I am not the only user of this website with a problem and all us having a problem have satellite internet (different providers), however not everyone with my satellite internet (wildblue thru dishnetwork) has this problem as I have asked here...some do some don't Wildblue ''blocking'' a website's ssl? - WildBlueWorld.com Forums
I can go to the website toontown.com but I can not access any pages that are ''secure'' or https. Can't login and using satellite internet?

Like others I see on this board, we've got middle- and high-school age kids whose access to FB and other sites needs to be controlled/scheduled.
I thought the DIR-655 was great, in that it has features that, on the face of it, would seem to be ideal for blocking domains and restricting access.
My problem: I've never been able to get this to work.
I've set up schedules and created lists of domains that I want to limit access to according to the schedules, but the only constraint I've ever gotten to stick is blocking access completely to the router.
*None* of the schedule-based or website-based access controls have ever worked; I'll put the block in place to my daughter's computer's MAC address so she shouldn't be able to get to youtube or facebook, save, bounce the router, but then I go by her room and she's still busily chatting away online to her FB friends.
Based on similar posts I've seen on this forum, this may not be a unique problem.
So in a nutshell, this is what I want to do:
1) Block certain computers (identifiable by MAC address)
2) from being able to get to particular named domains (and any of their sub-domains)
3) according to a schedule that I can create and modify.
My preference would be to do this in the router, but again, responses I've seen here suggest that may not be possible.

I went through all discussions regarding how to block access to some web sites. And I was trying to implement them but it didn't work. I've used 887G-3G-K9 router and UC540, and I'm not sure if it's possible to do that on them or I need to get a license for that or to buy ASA. How can I check that URL blocking is available feature on those devices?
I've used 2 methods:
1) ACL
2) class-map and policy-map
class-map match-any http
match protocol http url "*facebook.com*"
match protocol http url "*www.facebook.com*"

Has ASA5510-K8 as firewall, has access rules setup for restricted PCs: [code] permitOn those PCs, users can only browse the websites that are in favorites, but some of them are working, some are not.Test on unrestricted PC, websites that can’t be accessed from public PCs can be access on regular PCs , either by address or IP.Checked GPO setting, don’t see anything wrong there.
