inaki,

the comment is that currently uniqueness of gws is based only on gw's ip
address or hostname , i.e., port is not considered.  after quick look at
the code, it should be quite easy to add checking of port too.

i cannot comment on this one unless you tell why three tables are
needed.

if that is the port issue discussed in above, it can be done.

that already exists in 3.0 (see defunct column).

why can't you do this in the script?
