ashraful Posted November 29, 2008 Report Share Posted November 29, 2008 Hi all,I want to ask on how to block one of the user in my router wired from accessing the internet. Meaning remain the LAN access but blocked the internet access?i already block the MAC address of the user in my router DLINK DSL-2542B.but the thing is, he stilll can access the net.

scissorhands7 Posted December 4, 2008 Report Share Posted December 4, 2008 (edited) Are you sure you're blocking the correct MAC address? He shouldn't be able to access the web if its the correct MAC address.Edit: Removed the YouTube video link - no need to be rude.

scissorhands7 Posted December 4, 2008 Report Share Posted December 4, 2008 Editing = destroying some lulzOn many routers (especially linksys based) there is an option to only >>Allow<< MAC addresses Try only allowing the users you want and tell me if this works.

Pete_C Posted December 4, 2008 Report Share Posted December 4, 2008 In Bridge mode, this device is acting as a switch and modem; not a router.http://www.smartbridges.com/education/print-ready.asp?id=325You would use it in bridge mode if you had another router which was handling your network.http://www.dlink.com/products/?pid=562>2-IN-1 DEVICEThe D-Link ADSL2/2+ Modem with 4-Port Ethernet Router (DSL-2540B) is a 2-in-1 device that combines the function of a DSL modem and 4-port 10/100 Ethernet router. The DSL-2540B supports the latest ADSL2/2+ standards to provide higher performance (up to 24Mbps* downstream and 3.5Mbps* upstream) and longer reach from your Internet Service Provider’s (ISP) Digital Subscriber Line Access Multiplexer (DSLAM).Your router has a firewallFIREWALL+ Built-in NAT+ MAC Filtering+ Packet Filtering+ Stateful Packet Inspection (SPI)+ Denial of Service Prevention (DoS)+ DMZAccess your routerenter your admin name and password (side note, make sure you have changed these from the default of admin / password and do not use dictionary words. Othewise if you get zlobdns changer or similar trojans they can hijack not just your PC but your router very easily).(Do this on the tools tab admin section also this will prevent the other user from just changing the settings back)On the advanced tab => filtering outbound you can specify a computer and block it from getting out.The outgoing filter will block the LAN traffic from entering the WAN side.

ashraful Posted December 5, 2008 Author Report Share Posted December 5, 2008 Well, all i can say that is, i already blocked the MAC address from going to LAN<=> WAN direction.So, supposedly he can't access to the internet right?Is it because, the bridge and the WAN settings different from each other?like in the pic?But, if i have to do IP filtering, i don't know how to do it, because it has the destination and source and i don't know what it's for.Plus, i'm using DHCP server, so i fi block his IP the comp might be getting a new ip address then. haha.

scissorhands7 Posted December 5, 2008 Report Share Posted December 5, 2008 You can change your computer to run off of static IP if you'd like. Its personal preference. If you would like to go static IP i can explain how to do so. Quote Link to post Share on other sites
Pete_C Posted December 6, 2008 Report Share Posted December 6, 2008 You do not want to do mac filtering; use the firewall.Mac addresses can be cloned or otherwise masked http://compnetworking.about.com/od/network...ddressing_2.htmso, mac filtering is pretty useless.Just use the firewall on the router to block internet access by that computer.
