telnet proxy/gw choices?

[Neale Banks <neale () lowendale com au>]

Greetings all,

I need to provide telnet access across a BSDI box which has IP forwarding
disabled (for various good reasons).  For practical reasons, the proxy
needs to be transparent.  For security reasons, the proxy needs to listen
on only one interface.

Is there any real alternative to telnet-gw or plug-gw from the fwtk?

Thanks,
Neale.
