Hi,
I'm trying to set some rules for an output firewall, denying
access to some sites.
My linux box acts as a ip-masq for the internal sub-net of
Windows machines. It has 3 cards: one for output to Internet, with a
valid IP address and 2 for the internal sub-net.
IP-Masq is working OK; all machines can telnet, browse, ftp, etc
to external servers on Internet, being masquerade with the Linux IP.
I'm using this sintax:
# ipfwadm -O -a deny -S 0.0.0.0/0 -D some.site.denied/0
but isn't working, since I can connect the denied site from a inside
machine. What is wrong?
Does I need some other software in order to have an Output
Firewall?
Thanks,
[]s,
