When i want to active nat using iptable on eth0:0 (aliasing) "error appear"
# /sbin/iptables -A POSTROUTING -j MASQUERADE -t nat -s 192.168.0.0/24 -o eth0:0
Warning: wierd character in interface `eth0:0' (No aliases, :, ! or *).
If eth0:0 has FIX IP address, you should try SNAT:
# iptables -A POSTROUTING -t nat -s 192.168.0.0/24 -j SNAT --to IP_of_eth0:0
