D-Link DIR-655 :: Router Blocking University Sites
Jan 13, 2012
So I can't seem to access ANY site related to my university (www.concordia.ca) anymore from my home network. I've tried to visit URL or any of its' sister sites from my desktop, my laptop, my iTouch, even my ps3, I've also tried cross-browsing to no avail. I've checked the router page, apparently my Hardware Version is B1 and my Firmware Version is 2.00NA. Access Control is unchecked and there are no sites at all listed under Website Filter. I've also tried resetting using the reset-hole and also by pulling off the power chord. Also did a factory-reset from the router page, the problem persists despite all of that.Every other site works just fine, it's just my university site that refuses to load up. I've browsed the last 7-8 pages of this forum, this doesn't seem to be a common problem based on that little sample. So what gives exactly? I used to be able to visit those sites just fine prior to few days ago.
I am on a 200GB/month 100mbit cable plan with Telstra, and we have a number of sites/servers which we can download from which do not count towards our monthly download limit. Normally there would be 3-4GB of usage per day which was 'unmetered' but since upgrading to the E4200 router, everything that should be 'unmetered' is not being recognised and is being counted towards my monthly download limit - in other words, all traffic through the router is counted as chargable downloads.
Im not sure how it all works, but the E4200 router is definitely blocking something out... if i plug directly into the modem or use my previous router (WRT160N) everything works perfectly.
I using 881 cisco router and want to block secure sites. I am using classmap to block sites and accesslist to block secure sites. Now the issue is if i need to block youtube, and if doing tracert the IP of google and youtube is in the same subnet.
If i am blocking that IP, google is also blocking with youtube which i does not want. Need blocking youtube secure site only.I am also attaching tracert for both the sites.
I am currently at university, using a Local Area Connection. I am aware that the university blocks torrenting which I am totally fine with though when I try to carry out a process such as posting a large entry on Livejournal.com or Dreamwidth.org, it tries to load for a couple seconds and then fails. When in Google Chrome, it says that it's "uploaded 100%" but then I receive "Error 7 (net::ERR_TIMED_OUT): The operation timed out.". When using Internet Explorer, it either doesn't load at all or I get the standard "Internet Explorer cannot display the webpage". When I try to carry out a different process on dreamwidth and livejournal (editing my layout), Chrome tells me "Error 101 (net::ERR_CONNECTION_RESET): The connection was reset." These issues always happen no matter when I try them.
I have a LAN with several linux boxes (Fedora 17, both 32 and 64 bits), as well a a WInXP box. All of these are connected to the same switch, which is connected to the inside port of my PIX 515.
For a few sites (mozilla.org happens to be one of them), for http access, the tcp connection is established, but the "GET" request - or anything else for that matter - will not go through the PIX (from inside to wan). I have verified this by first, using wireshark to watch the packets being sent out from the client box, then by using the trace function in the PIX to see that the packets ARE arriving at the inside interface, but ARE NOT sent out of the wan interface.
This is for the linux boxes ONLY. When I do the same thing with my WinXP box, all works: in the PIX trace, I see the packets arrive at the inside interface, and leave the wan interace. And access to these sites are okay.
(What's a bit weird, although somewhat expected, when I connect my android phone to my LAN via WiFi, it too is unable to reach those sites - but then again, android is linux, right?)
In addition to the tracing, I have narrowed this problem down by connecting a linux box directly to my DSL router, then replacing the PIX with a simple router/gateway. Both of those solutions work.
I have been using this PIX for about 10 years now, with the same configuration (except IP addresses). Only in the last several months has this problem started to show up.
I got this pix from a dead company at a really great price (free), so I'd like to keep it, and not have to spend money on something else. I don't have any support license, and have not been able to get any software upgrades. Here is its version info:
taz(config)# sho ver
Cisco PIX Firewall Version 6.2(2) Cisco PIX Device Manager Version 2.0(2)
I just installed a TP-Link router. Everything (almost) works: PC internet, laptops internet, email, etc. An application on my PC can't communicate through the router to the internet server now. I am sure it is a port/IP address issue. But I am unable to figure out a solution. I have already changed the IP (of the computer with Windows 7) to a static IP address. I guess now I need to get the port access done. I know the ports in question from calling the vendor. I just need to get the application through the router.
Im using d-link 855 router to block internet to certain machines, using access control within dlink and then in putting the ip for the right machines. But it seems the machines keep changing the IP adresses everything they boot thus getting internet access the next day.
I have fiber optic net, going into a TP Link 1043 ND router out in my garage.All of the 4 lan ports go into one of the rooms in the house. I also have two more routers of the same kind, one downstairs and one upstairs.They are configured in a way, that DHCP server is only turned on, on the one in the garage, the other two act as switches.My problem is that 50 % of the time I can't acces facebook, and some other random sites.The interesting bit is that when I chat with someone on FB, I can see what they write, but my message doesn't go through.The way it goes, is that I can browse on facebook for like 5 minutes, after that its unavailable for another 5 minutes.I can still access the site from my smartphone, but only if its not connected to the wifi network, meaning the problem is somewhere within my setup.I've already tried turning the router firewall off, but that doesn't make any difference.
l have a web-site and when l go on it it comes up with blank page internet explorer cant load this page.l have phone talk talk and they cant fix it.l have a d-link router,its only my own web-site l cant access all other web-sites l can access.
Until yesterday my various equipment was networking to each other and the internet without a problem. After i reset my d-link DSL-2640B router (would this initiate an update?) my x-box would not connect to the internet, There is no problem connecting to the router and the home network. Everything is talking to each other and everything else is connected to the internet including the TV. The router must just be blocking the x-box and only from yesterday. I checked ports that are talked about and i think i set up port triggering, but then noticed the firewall is disabled anyway.
I have a DLink DIR-615 rev. B2 firmware 2.25. A few days ago, I started using Comodo Unite for VPN access with friends and LAN gaming. However, just recently the program stopped working correctly. I have reset my configuration, tried multiple different settings, and nothing at all has remotely worked.
i have a adsl modem tp link td 8840, and i had this up and running well for about 3 days. then we decided to get a router cause my little sis got a ipad2.the router is dlink dir 61.so basically i followed all the instructions and the internet was working fine.then for some reason ign site stopped working, i thought that it was down for some reason and didn't think much of it and today when i tryed to go into hotmail or facebook it doesn't work either. so i can get into the log in pages of both, but when i put in the id and password, the screen goes blank and just says waiting for .... on the bottom (using google chrome).and it never loads.i tryed with other internet browsers and it din't work so i took out the router and re wired the adsl modem only and voila. all the sites started working again.i want to use my router but i don't know why i can't acess some sites when i have it connected.
The building's IT specialist has provided a program I think he made himself which changes a computer's settings to allow the user to log on and enter their student username and password in order to connect to the internet.Usually, when I get back from his place, I:plug in my Ethernet cable,open network and sharing center open the properties for my wired connection go to authentication and untick 'enable IEEE 802.1x authentication'and this works fine. However, I came back from his house two days ago and this did not work. I've tried system restore multiple times, rebooting, unplugging and plugging in the cable, and even going back to his house, setting myself up there and coming back to test if I can get back to normal again.
I was connected to my university's network through VPN from my personal computer. All websites are routed through their servers. Many people connect and use the network.I forgot to turn the VPN off and went to an xxx website. Actually I watched a video on megavideo. Then I realized the VPN was on and turned it off.My question is, can an automated system determine what I did and will any IT person go ahead and click the link to see the video?
I followed the instructions in the manual for checking and changing the MTU on the router. It didn't have any effect. When I take the router out of the system and go directly to the modem, I can get the sites.
I have two sites linked by fibre a few miles apart, site A is on a 10.0.0.0 range, site B is on a 192.0.0.0 range, at site b there is a firewall with 2 cards, Site A also has a firewall, it external is poiting to the internet at site B, so basically site A get it internet from site Bs internet. Now they have decided that site A needs to be able to have access to one sql server at site B, how can this be achieved without allowing all traffic across the link, as, for example, both sites have their own DHCP for and cannot have site A giving out IPs to site B, so its a bitmore complicated than just linking the two can it be as simple as a masquerading rule at site B, with a second card in the sql server or 3 VLANs at site B (one for site b one for site a and one for the external internet, with site As traffic tagged), idk i cant get my head around it.
I have just started using D-Link 655 router and ATT DSL connection at home. There is an internet signal. Skype is working. But I can't open any sites. Ie tried typing hotmail, Google, anything - sites do not open. Ive tried to plug in the Ethernet cable directly into my laptop and I get the same result sites don open.
I have dir655 Hardware Ver B1 Firmware Version: 2.10NA.Comcast Motorola cable modem surfboard SB5101. The problem started happening a couple of days ago. When my computer is hooked up to the cable model directly, i am able to connect to outlook.com just fine but when i go through my router, it can't connect to the site. I played with MTU (lower it by 10) all the way to 1300 but it didn't work.The problem started happening all the sudden without any changes in the cable modem, router or my computer.
I also tried cloning MAC address from my pc but didn't work.I also tried turn off both modem and router, wait 2 minutes, start modem, wait for all lights to come up and start the router.Sites i can't connect are: outlook.com, starcraft2, Comcast, eBay, Facebook.One thing that i noticed weird is that i am able to connect to cnn.com using IE9 just fine but ping shows: [code]
MY ISP installed one router in my lab.for internet connectivity they mail me steps :connect your Laptop directly to gi0/3 port to check internet connectivity with public ip 1.1.1.x and Gateway 184.108.40.206 with subnet mask 255.255.255.240 after connection I surprised because I am able to access only google sites like gmail,google search etc. but I am able to ping/traceroute all sites.from browser I am able to access only google sites only.In Router no firewall no such access list.
For the last week, I haven't been able to access my banking web site (Royal Bank in Canada). It doesn't matter which browser (FireFox, IE, Chrome) or computer (desktop, laptop) or even my cell (on WiFi).It must be the router (DIR-825, HW-B1, FW-2.07NA) since I can connect to the web site fine if I connect straight to the modem. (Also, if I turn off WiFi on my cell, I can connect to their web site but once I turn WiFi back on, it wont connect).I tried restoring to factory settings but that didn't work.I tried some of the suggestions here: http:[url].....
- Turn off ALL QoS or Disable Traffic Shaping. Advanced/QoS.
- Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
- Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking
- Ensure devices are set to auto obtain an IP address.
- Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
- Enable uPnP and Multi-cast Streaming under Advanced/Networking.
I have a dir-655 a3 router that is blocking my website ip address.I could previously access this site until one day, without changing any router settings, it started blocking communication to my website. pings, tracerts, web browsers, everything simply times out. It resolves the IP address ok but doesn't go any further than that. I was on firmware 1.31 and have now upgraded to 1.35NA, but no luck. I have also tried resetting factory defaults to no avail. If i bypass the router and plug my computer straight into the modem, the site loads fine. so its definitely the router. I have tried this on a number of devices to make sure. It appears that for some reason the router is blocking that specific IP address as it is on a shared hosting and I can't access any other sites on the same IP address. Does the router check the IP address with any web service before returning the request?
within ACS 5.3, I'd like to use 2 external authenticator for the same service, like vpn remote-access.For the authentication, I know I can create an identity chain, to query SecurID and then AD, in case of user not found in SecurID.For the authorization rules, I need to provider a wide vèn access for SecurID users and narrow vpn access for AD user.Are there some parameter to use in compound conditions for SecurID ?
Is there a way to block specific computers on the LAN from specific web sites by the domain name? All I can see is that if I put, for example, www.facebook.com, it will be blocked from all computers on the LAN, whereas if I want to block only 192.168.1.3 for example, I have to use the IP address through the Access Control, which is much harder and ****e to some "work around" by the user.
Have a Rev. B1 w/207NA on Time Warner with a Moto Surfboard SB5150.Working with TiVo's, we've been through hell and back trying to resolve why Multi Room Viewing doesn't seem to want to work - but only one way! The newest TiVo's their Premiere model with HD and all the bells and whistles, it sees the other TiVo and all the other software that can send programs back and forth with it.
I brought on a Series 2, which is an older model that's non HD and has some older software in it. While the Premiere and the other PC's/Software around the building's network can 'see' the Series 2 and it can 'see' the other shared PC's, etc. the thing can't 'see' the Premiere.This has been going on for awhile, I've worked with TiVo Support also to unlock ports, IP addresses and anything else we could think of. Still no luck. Then we had a strange occurance!
The DIR-655 seemed to 'lock up' or disconnect from the Net. One day I was surfing the Now Playing menu in the Series 2 and the other TiVo wasn't showing as usual. I checked it again during a commercial for something totally different and suddenly noticed there it was!! I thought it was weird, so I went out front to check with the person using the main TiVo if they had made any changes or done anything - they hadn't, but did mention their Net connection was gone.
I turned around and looked at the 655's status lights and noticed while all the rest were fine - the WAN/Net status light was totally out. Not a single blink. And then I looked at the Moto cable modem and noticed it's 'activity' light was also totally dormant. I twisted the Moto to get a better look at it and things started working again, I tightened the cable modem cable on the rear and that was it.
From that point on - once again, the front TiVo won't show on the back TiVo! Does every other way, but not that. In our discussions on TiVo we thought it could've been the cable modem firewall or something, but I retested it and this time it had NO effect. Tried not only taking out the cable-cable but the Ethernet cable as well to ensure all were tested. Still didn't now up. What I thought was going on was the 655 had turned into a giant 'Hub', which would've caused the TiVo's to use their old-fashioned Beacon software to 'find' each other. When the 655 software kicked back in from that glitch, the hub setup would've obviously stopped and the 655's software settings would've kicked back in.
I have a complete list of the ports internally that need to be open for those two TiVo's to communicate, but I can't find anything in the 2.07NA GUI (or Help manuals) that tell me how to write a rule to open those ports internally. I wouldn't think there's any internal blocking or firewalling going on (I have it set to allow communications between clients on the internal Net) but there's so many settings in this GUI it makes your head spin!
I need to restrict access or rather, block altogether if i can, access of one of the computers on my local wireless network, to online multi-player gaming sites, in particular Age of Empires and Voobly.com, which also uses a messenger type program for them to chat.I've searched and searched online, but alas, have come up with nothing that i understand. I've tried doing the block ports thing, but am unsure if what i've been doing is right. I have blocked Voobly.com under domain and URL settings via the router admin page, but for some reason, it only seems to be denied on my computer. I even went so far as to register and download relevant programs to my computer, for Voobly, so i could see if the blocking worked. Seems it's only my computer that's blocked, i didn't specify ip or mac addresses.I am unable to get on the other computer as it's not mine, and it's also password locked. I don't know the password
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've blocked all traffic on port 80 (Advanced-Access Control- Apply Advanced Port Filter- All IP range and Port 80 selected) to avoid any kind of Web Access. I won't use Web Filter because there are too many URLs to be blocked.
However I have a problem to keep Google Earth working, since it uses port 80.
Is there a way to keep Google Earth working, even blocking traffic on Port 80? I've tried configuring an application rule to let Google Earth working, but it didn't work (it seems that I can not create an exception for Filter Port) .
My TP-Link 8817 which is connected to my ASUS RT-N66u appears to be blocking my ports. I port forwarded on my router to set up a server. I do have the right IP and ports set up. Originally i thought it was the router but then "netMakeChannDial: err=-3000 rn_p=8050dc14" appeared in the modem log but nothing in the router log even though i turned on the "logged packets type" to Both. I have googled this error but nothing came up so I'm probably just doing something stupid. I have even tried turning off the modem firewall and SPI, but still no luck.
