However, I have problem doing ftp. ftp using unix box is fine. But windoz ftp client has problem. Although I have configured it in passive mode. I use ftp explorer. It says "error connecting to: ftp.netbsd.org"

In /etc/ftp.conf set

portrange       all     1024    5000

which assigns a port range between 1024 and 5000. Using the following
entry in /etc/ipf.conf will pass these packets in passive mode

pass in log quick on ppp0 proto tcp from any to any port 1023 >< 5001

You may want to choose a different port range which suits best your
system

Hope this helps
