Linux behind MS Proxy firewall

I have recently set up a Slackware Linux box (kernel 2.0.35) on our lan.
Our proxy server is MS Proxy on an NT machine.

I can access the net eatily through Netscape with the browser's proxy configuration but also wish to use command line telnet, ftp and other network utilities. I am searching for a seamless solution.

I have the NT box set as my default gw in the linux routing table but it doen't do anything because the NT box is not only a gateway but a firewall.
the NT box is and the linux box is
If anyone can offer a seamless solution I will pay with many points.

Thanks in advance,

You don't mention what NT firewalling/proxy capabilities, but:

1) you need a proxy server for EVERY service you want in your Linux AND a client (say the telnet command) that knows how to use the proxy


2) If your firewall supports it, configure Network Address Translation or Masquerading


3) Configure a SOCKS server (maybe there are some free implementations) and install socks clients in Linux. Almost everything will work...
Does MS Proxy Server even offer FTP and Telnet proxies?

we have all of the required services enabled in our proxy server, telnet ftp, a few others, but these are the things that matter...
socks stuff
