Here my firewall configuration:

Now the REDIRECT rule is activacted in status.txt

eth0: 192.168.0.254 (wan - connected to ADSL)
eth1: 172.16.1.254 (lan)
tap0: 192.168.99.1 openvpn

zones:
fw      firewall
net     ipv4
loc     ipv4
vpn     ipv4

interfaces:
net     eth0            detect
loc     eth1            detect
vpn     tap0

masq: 
eth0                    eth1
eth1                    eth0

squid is running in 8080 port.

In messages i see:
Oct  8 19:48:25 farroupilha kernel: Shorewall:FORWARD:REJECT:IN=eth0

We basically don't have enough information here --

a) If Stacker's users are accessing the internet directly now, how does
adding the rule disrupt them if, as claimed, the rule does nothing?

b) As Fabio says, we're assuming that Squid is running on the Shorewall box.
But even if it isn't, that wouldn't cause the users to "try to go directly
to the por (SIC) 80 using  the default gateway". So I suspect that the rule
is working and Squid is not.

Because:

- In 90% of cases where transparent proxy doesn't work, it is the Squid
configuration that is wrong, not Shorewall.
- In 9% of the cases, the user forgot to enable port 80 from fw->net even
though that is carefully documented at
http://www.shorewall.net/Shorewall_Squid_Usage.html
- In the other 1%, the user is astonished to learn that HTTPS cannot be
transparently proxied.
