gracias,

our (172.24.33.0 <http://172.24.33.0>) LAN goes to internet through two
proxies, the new proxy which is the one i am trying to set up, is in anothe=
r
network
we have set routes to that LAN, (172.25.1.0 <http://172.25.1.0>)

-is it inappropriate to put these address here? i hope not :s

in order to be protected, we have set a firewall in this way:

LAN(172.24.33.0 <http://172.24.33.0>) --> SWITCH --> fw --> Router(
172.25.19.X) --> proxy(172.25.1.5 <http://172.25.1.5>)

i have the other conf (using another proxy, another network) without the
string 'http://' and it works, and transfer everything.
and besides, using the new proxy, without the 'http://' string, it shows
bytes activity in 'ipfw show', i mean i can enter sites.

For using "open firewall ruleset" do you have any basic document?

another hint or help, will be appreciated, thank you.
