redir-dbgsym binary package in Ubuntu Xenial i386

 It can run under inetd or stand alone (in which case it handles multiple
 connections). It is 8 bit clean, not limited to line mode, is small and
 light. Supports transparency, FTP redirects, http proxying, NAT and bandwidth
 limiting.
 .
 redir is all you need to redirect traffic across firewalls that authenticate
 based on an IP address etc. No need for the firewall toolkit. The
 functionality of inetd/tcpd and "redir" will allow you to do everything you
 need without screwy telnet/ftp etc gateways. (I assume you are running IP
 Masquerading of course.)
