Only thing I can say is to not give the address to the alias but see 
what happens if you just give it to eth3.

I don't know how you assign it but if this is your public IP then of 
course there is no such thing as "Virtual IP". They are just two IPs 
assigned to the same interface right, which is perfectly normal.

IPtables chokes on eth3:1 syntax though. Do not use it for your firewall 
pls :).

Regards.

Or if you do: iptables-save | sed "s/ eth3:. / eth3 /g" | 
iptables-restore

But maybe it is completely different, I don't know, it's just odd I 
guess to me.

Regards.
