Allowing FTP and TELNET through firewall.

[mnejat @ rasht . alsys . com (Mehregan Nejat @rasht)]

Hello,

I need to let users at our site to do FTP and TELNET to outside world
without having them login to our firewall machine first.  If I just add
a default route from lets say hosta to our firewall machine(i.e.
route add default firewall hosta 1) then I can ftp and telnet from hosta
to any host on Internet(assuming Internet hosts let me do that).  Does this
scheme create a security hole in our Internal network? If so,  what are
my alternatives?  


Any help is appreciated,

Thanks,
