Hello, I would like to know if does it possible to capture just the
first connection og one user with a iptables rule and redirect to a
specific ip/port address.

I have a intranet with a proxy machine with squid on debian for to out
to internet, and I would like that when I user connect for first time,
a iptable rule redirect it to a welcome page.... but just the first
time ..

Does it possible to do this with a iptable rule??

Thanks a lot

This is probably possible with the recent match. Somthing along these 
lines (untested!):

-t mangle -A PREROUTING -p tcp -dport 80 ! -m recent --update --seconds 
3600 -j REDIRECT --to <welcome-page>
