Look at; some of this was covered within the past
week, I think.

IF you use the CERN httpd as a proxy, then it will handle FTP for you;
it will run on the firewall and talk FTP to the world and HTTP to your
Mosaic, Lynx, or other proxy-capable browser.  Your browser will
launch a telnet session for you when a telnet URL is selected.  This
is problematic with the TIS toolkit, since the browser will exec a
'telnet 3000' command, whereas you really need
to telnet to the firewall and issue a 'con
3000' command to the proxy.  I've not tried to crack this nut, yet.

You have two choices in running the proxy itself; run it as a daemon
using its own authorization mechanism, which is similar to TIS', or run
it on-demand from inetd via netacl to use TIS' auth mechanism directly.
That is less efficient in terms of process spawning on the firewall,
but centralizes administration & logging.
