Hello, eth0:0 is an alias to eth0 -- so in iptables you must reference the interface (eth0) and they also go by destination (-d) So in the following example: eth0 = 192.168.0.1 eth0:0 = 10.10.0.1 iptables -A INPUT -i eth0 -d 192.168.0.1 -p tcp --dport 80 -j ACCEPT will allow port 80 for the 192.168.0.1 network and iptables -A INPUT -i eth0 -d 10.10.0.1 -p tcp --dport 25 -j ACCEPT will allow mail for the 10.10.0.1 network.
