Eu preciso alugar vários endereços IP do servidor DHCP e usar simultaneamente todos eles em um único computador.
Deve ser conectado da seguinte forma: computador com 5 endereços IP locais: 192.168.1.2-6 conectado por porta LAN ao roteador openwrt que alugou 5 endereços IP com 5 portas WAN virtuais, cada uma com um endereço MAC diferente.
Consegui que a segunda parte funcionasse com o pacote kmod-macvlan. Minha configuração está seguindo: /etc/rc.local:
ip link add link eth0.2 eth1 type macvlan
ifconfig eth1 hw ether 54:E6:FC:B7:00:00
ip link add link eth0.2 eth2 type macvlan
ifconfig eth2 hw ether 54:E6:FC:B7:00:01
ip link add link eth0.2 eth3 type macvlan
ifconfig eth3 hw ether 54:E6:FC:B7:00:02
ip link add link eth0.2 eth4 type macvlan
ifconfig eth4 hw ether 54:E6:FC:B7:00:03
ip link add link eth0.2 eth5 type macvlan
ifconfig eth5 hw ether 54:E6:FC:B7:00:04

Agora, como é que digo ao router para emparelhar os seguintes endereços de IP estáticos às portas WAN virtuais:
192.168.1.2 - eth1
192.168.1.3 - eth2
192.168.1.4 - eth3
192.168.1.5 - eth4
192.168.1.6 - eth6
A rede fica inacessível para 192.168.1.2 depois de entrar
ip route add 192.168.1.2 dev eth1
