Title: Block Bad Guys With R2's Nifty New DHCP MAC Address Filtering Tool Post by: Tanya on November 16, 2009, 07:01:40 PM Block Bad Guys With R2's Nifty New DHCP MAC Address Filtering Tool
Basically, here's what R2's DHCP Server can do with MAC address filtering: Either block any particular MAC address from getting an IP address, or allow any particular MAC address to get an IP address. Arrange the question of gets blocked from and who gets allowed to have an IP address either as a whitelist (no one gets an IP address unless their MAC address is on the "allowed" list) or a blacklist (everyone gets an IP address unless their MAC address is on the "deny" list). By default, DHCP runs as a blacklist with no IP addresses on the "deny" list. R2's DHCP server lets you enter one or MAC addresses into its filters in several ways: hand-enter the MAC address into the GUI (ugh) hand-enter a range of MAC addresses using "*" as a wild card (better) select a bunch of systems that already have a DHCP lease, right-click them and add them to either the allow or deny list with just a few mouse clicks (even better) feed the DHCP server a text list of MAC addresses use a new command-line tool to enter one or more MAC addresses Continue: Mark Minasi Newsletter #82 The New DHCP Server in R2 Email it! | bookmark it! | digg it! | reddit! http://feeds.bink.nu/~r/binkdotnu/~3/J_LtTHT_-rU/block-bad-guys-with-r2-s-nifty-new-dhcp-mac-address-filtering-tool.aspx |
