Hello

I am doing this and saving lots of money:

    | 1 Mbps            | 2 Mbps
    | US $2500/mo       | US $450/mo
--------            --------
|Router|            | ADSL |    ------
|      |            |modem |    |new |
--------            --------    |ADSL|
    |                   |       ------
    |ex0             ex0|         |
--------            --------  ---------
|NetBSD|            |NetBSD|  |new box|
|ipf   |            |squid |  | here  |
|ipnat |            --------  ---------
|      |             ex1|         |
|      |  Redirect LAN  |         |
|      |-----------------   -------
-------- ex1
ex2 |
    | Private LAN
-------------------------


I would like to get an aditional ADSL line
(512 kbps, US $50/mo) and one more NetBSD box
and connect it to our "Redirect LAN".

This if for redirect gnutella and kazaa protocols
which are eating our main line (1 Mbps).

Question:
Is this possible?
If "yes", what do I need in the new box? (ipf/ipnat)?

Socks5 is not a solution for me because there are
lots of student machines in the private network
and is practically impossible to find it
and configure them to use socks5.

TIA
