Hi there,
I am helping a friend setting up his network. I put
a FreeBSD machine between the cable modem and
the three Windows 98 machines they have. The
FreeBSD is running natd, socks5, ssh, named and
nothing else. The socks5 is for them to use ICQ, napster,
etc., and only response to request from inside. The FreeBSD
also filter out source route packet and private addresses
on the cable modem side. All packet types are allowed
into the FreeBSD machine.
I am failing to see the reasons for adding extra packet
filtering rules. natd will not forward packets for connection
that it does not know. socks5 will only create a listening
socket for applications inside requesting it.
I must be missing something. What am I missing?
