I've came across IP address that aren't enough for some users in the company. The IP addresses are more than enough to cater to the user's notebook or PC. However, some users does not know that there are actually limits to the IP we have, so quite a number of them actually uses their mobile / pads to tap the company's wireless.
I was wondering if i could restrict that particular user from tapping onto the network. I know it sounds a bit impossible because DHCP doesnt have that smart function to block whoever we sees deemed as a "nuisance".
Bought DIR-655 from Amazon. Rev. B. Come with 2.00NA firmware. Updated to latest one, and there are a lot of problems, to most of them, I was not able find any solution. Here they start:
1. WIFI SPEED PROBLEMS.No matter what speed, parameters, channel, mode, etc I select, router keeps working on 20mhz channel width. So I never get speeds above 65 mbit. In absolutely same conditions, my DIR-300 B1 (with DD-WRT firmware) gives me stable 150mbit. SO I KINDLY ASK, MAYBE THERE IS A WAY TO FORCE "40 MHZ ONLY" OPTION?
2. PASSWORD PROBLEMS.Router came with no admin password, I enter new password, hit "update" it says - wait 20 sec, after that, login page is displayed, but, new pasword does not works! since it asks again for empty password!
3. FILTERING PROBLEMS.I need to block certain IP address to be accesed by all my computers. Say this is 22.214.171.124 . So I added inbound filter rule, to block access to that IP. It does not works - IP is still accesible.
4. MORE FILTERING PROBLEMS.Since above mentioned method does not works, I have to use "ACCESS CONTROL" feature. It does works, but it causes another problem, with access control enabled, all webpages with form submit stop to work. For example, if I'll have that feature enabled, when I press "post" on this webpage, it instantly will go to "this page cannot be displayed".
I bought this router solely for one purpose - I was happy with speed of my DIR-300, but I needed gigabit for my computers. So I thought, instead of buying separate switch, I'd better buy a router with gigabit. I was suggested to get TP-LINK 1043, since it's quite popular, alternate firmwares available and so on, but I refused to buy it, since I thought that some chinese company does not worth my attention. So I bought this D-Link (for almost 2x price of TP-Link) and having huge problems as you can see.
I want to do what I thought would have been a simple enough task - block my kids phone/computer after certain hours. Instead of blocking the specified MAC address(es), all my computers does not have internet access. As soon as I disable the policy, internet access is on again. Here's what I did:
I've been keeping an eye on my IPS report tab lately and have been watching a large number of ICMP_SMURF and DOS attacks originating from chinese ip address's. I know I can probably block the offending ip's through the ip based acl tab in the firewall settings, but I'm kind of a newbie how I can block certain ip's from touching my router?
Recently, I've been having significant problems with denial of service on our ASA-5510. Two IP addresses in particular attack my ASA regularly. What kind of rule do I need to create to deny these IP's access to my firewall?
I have a WAG160Nv2 and I want to block specific external ip addresses from trying to get at our server that uses the WAG160Nv2 as an internet gateway. It's not immediately obvious if this can be done from looking through the config pages.
So if the PPTP server is enabled, and "Block MAC address not on the list" is enabled under the DHCP settings, will the PPTP client get an IP address?Similarly, if the PPTP server is enabled and the range of IP addresses configured on the PPTP server screen is outside the IP range of the router due to a subnet mask (like 255.255.225.248 for example), will the IP still be assigned to the PPTP client? If assigned, will that IP have any connectivity to the LAN?
I have a Windows 7 machine connected to my TV set. I want this machine to act as much as an appliance and as little as a PC as possible. To that end, I want it to be able to access my NAS disk, but not the Internet. Internet = annoying update messages (think Adobe), viruses, crap.I don't know if this is a setting that I can do in Win7 or in the DI-Link AirPlusG router thing
I have installed CSA on windows 7 with rule to block rpc port 135.But when i am scannig this host, this port is still opened.I changed OS to Win Vista,Win7 x86, but there is no changes.Is it possible to block port 135 using CSA on windows 7?
I have a windows server 2003 ent., with about 6pcs and a couple of macs. I don't want the server to connect to the internet, though every computer only has one network card. I want all the clients to access the internet but not the server. How do I set this up.
partition the departmental IP network address block to create a staff and a student subnet. Each of these will be identified by its own network address and netmask. It is university policy that you must be economical with the IP addresses. That is, the subnets must be as small as possible, but they must be large enough to accommodate the maximum number of hosts you were given. Also, it is university policy that the respective gateway router to the outside world should always be given the highest possible host IP address in the subnet. The student subnet should have a higher IP network address than the staff subnet. The network must be able to support up to 60 machines on the staff subnet (not counting the router) and up to 120 machines on the student subnet (also not counting the router).
IP address/netmask University network address127.158.128.0 University network mask255.255.192.0 University internet gateway IP address127.158.191.254 Department network mask255.255.254.0 Department router address127.158.129.254
Suppose that the network address of the departmental network is 127.158.128.0 (calculated by AND between Dep network mask and Dep router address)I know that 60 machines would use 6 bits for the staff subnet.the netmask of staff would be 255.255.255.192.how can I figure out the the IP network address of the staff subnet.I have worked out the range for the staff subnetwork.
I have been looking into this router, I would like to know if I can enable Parental controls or access restrictions to block a MAC or IP address; from 03:00 AM - 06:00 AM ?Instead of Midnight to 6:00 am.My E4200 works just fine, Just would like to know if the EA6500 Can do that ?
I am interested in knowing how to check on my 2003 Server what usernames are blocked from downloading. Many of the clients seemed to have downloaded Google Talk and also Spotify. I was wondering if I can check -where it is located and how to enforce this policy. (or create it if it isn't in effect correctly)
Is it possible to have my file server only accessable in the LAN. I would like to block all inbound/outbound traffic outside of the LAN. I back up all of my personal files to that server and some contain sensitive information.
I have cisco ASA 5510 with basic configuration (default policies). The problem is that windows XP users are unable to send emails form MS outlook and unable to log on to Hotmail , Gmail or any mailing site. While windows 7 and 8 users are not facing any problem.
I am registered on a chat sight but for the past week and a half each time I go on I can login and then I get a "Error receiving data from server:Connection reset" what can I do to fix this problem? I have the newest java downloaded
I bought a usb printer server to connect my usb printer to my router. USB cable to the print server and cat 5 from the print server to the router. The print server has a static fixed ip of 169.254.10.10 and a subnet mask of 255.255.0.0 I can ping the printer server and it works perfect from my windows 7 laptop. When I attempt to set it up on my windows xp (SP3) laptop I am not even able to ping the 169.254.10.10 address. On the windows 7 laptop i can navigate to the print servers menu by placing 169.254.10.10 in the address bar of internet explorer. No so with the xp laptop.What is different about the ip configuration between win xp and win7. how to get the xp laptop to "see" the print server. Want to keep the print server at the default settings if possible.
