That is true. However, it seems like a good idea to filter that way. Will
this do the job?
iptables -P INPUT DROP
iptables -A INPUT -i eth0 -d ! 212.127.242.126 -j DROP

as the first rule of the input chain (and after that a dozen other rules)?

I am no hero when it comes to iptables (still a bit newbie) and it is a
bad thing when you think a firewall works when it does not.

Thanks,
