Hi!
I have installed IPFilter3.2.9 on my FreeBSD2.2.1. During the installation
it gave me a lot of warnings saying that something wrong with some
variables in C-files. But everything seem to work properly, at least
ipnat. I am not too keen in IPFilters yet and can not fully understand how
to configure it. Can you help me in two cases:
1. One computer serves as a Proxy-server and Firewall. It has two
network cards. One connected to the Internet and the other to our LAN.
I want:
a) both inside and outside users can use the Proxy(tcp port-3128, udp
port-3130);
b) inside users can receive their mail from the outside email-server
(popper)
c) All other things are prohibited. I mean to say nobody can connect
to the computer, with the exception of I can telnet and ftp to it
from a dedicated computer in my network.
2. One more computer serves as DNS, email(sendmail and qpopper) and
terminal server for the connection of the remote users using ppp.
I want:
a) All the traffic can be passed through the computer between the
remote users and Internet freely;
b) The computer can serve:
- DNS requests from anywhere;
- receive the mail from Internet and deliver it to the users and
vice versa (popper);
c) All other connections to the computer are prohibited, except one
dedicated computer in my network.
Thank You.
