UNIX for Dummies Questions & Answers

Work with FreeBSD with firewall ipfw + dummynet and I need to allow to some IP by MAC address and to deny to the others, since I can do it?

Thanks.

Take a look at this thread it has explanations and examples.

## EXAMPLE ONE

-f flush
add 150 allow ip from any to any layer2 mac-type arp
add 160 allow all from 10.0.1.1 to 192.168.1.0/24
add 161 deny tcp from 10.0.1.0/24 to 192.168.1.0/24
add 162 deny udp from 10.0.1.0/24 to 192.168.1.0/24

#
#MAC ADDRESS USERS
#
#User 1
add 180 skipto 201 MAC any 00:30:f2:c4:09:02 in via vr0 layer2

#Deny all other mac address
add 200 deny MAC any any in recv vr0 layer2

add 201 divert natd all from any to any via rl0

#
#BANDWITH
#
#
add pipe 1 MAC 00:30:f2:c4:09:02 any
add pipe 2 MAC any 00:30:f2:c4:09:02

pipe 1 config bw 10KBytes/s
pipe 2 config bw 10KBytes/s
