MAC Addressfield, enter the MAC address of the ddevice as seen below. In the General tab, select chain as forward Method 2: Whitelisting the device using the MAC address (AA:BB:CC:DD:EE:FF) The rule needs to be placed above the "Block Facebook" rules added for the entire network.ĭrag this rule above the Block Website filter rule. ip firewall filter add chain=forward src-address="192.168.88.10" content="facebook" action=accept comment="Allow Facebook" The MikroTik terminal command for adding the above rule is as follows: In the 'Actions' Enter accept in the Action fieldĬlick on Comment to add a label "Allow Facebook" to the rule. In the 'Advanced' Enter 'facebook' in the content field Address as the IP assigned to the device (192.168.88.10) In the General tab, select chain as forward and Src. In the 'IP>Firewall>Filter Rules' tab, Add a new rule '+' Method 1: Whitelisting the device using the IP address (for example, a particular device is assigned 192.168.88.10 IP internally If a single device is to be given access to a blocked site, there are two methods through which this can be done: Let's assume first the network has blocked access to 'facebook' for all users and we are given the task to allow few devices/users to access facebook while access for others remain unchanged.
If a website is blocked across all networks, or on a certain network, but certain specific devices need to be given access to these sites, then we will create another filter rule and place it above the existing Website Blocking rule. You can also use an OUI lookup tool to help identify the manufacturer of each device.How to whitelist users to access blocked websites on Mikrotik

This question provides more information on how to do that. Once you have the MAC addresses of the two devices, you should be able to tie them to specific switch ports. There should be one IP address that flips between multiple MAC addresses again, those two MAC addresses represent the devices you are interested in. If the IP address in question is within one of your DHCP pools, it's also worth checking your DHCP server's logs for the MAC address it's attempting to assign that IP address to.įailing that, I would recommend logging on to the default router of the subnet that this problem is occurring on, and monitoring the ARP table. What device logged the IP address conflict? Was it a server, router, etc.? Some platforms (Solaris and BSD) will log the MAC address of the offending host along with the error message. I would suggest that you attempt to find the MAC addresses of the two machines that are clashing. 13Ī list of IP addresses on the LAN will be of limited help, as the issue is there are two machines trying to use the same IP address. If there's a unix box on the network, you could try arp-scan:ĪRP scanner | Linux man page $ arp-scan -interface=eth0 192.168.0.0/24
