[pox-dev] NATting using POX Controller

[kk yap]

Hi,

I am curious on why NAT is not possible.  The basic requirement of NAT is
look at the IP addresses and TCP ports, rewrite those, then install the
reverse flow similarly.  This should be doable in the most basic of
OpenFlow switches. Are you trying to do this in a proactive manner?

Regards
KK
