This kind of usage requires static interface names. But there are 
dynamic interfaces such as ppp, where the actual name is not always 
known or sometimes they exist sometimes not. It is difficult to use 
iptables this way, and every ifup/ifdown requires change in the iptables 
ruleset (donwload it, modify and upload to the kernel). It may be too slow.
