Redir redirects tcp connections coming in to a local port to a specified address/port combination like this:
The following redirects incoming web requests from 10.10.0.1
to 10.10.10.1:
redir –laddr=10.10.0.1 –lport=80 –caddr=10.10.10.1 –cport=80
And here the same for ftp. Note the –ftp option, this makes sure both passive and active ftp work.
redir –laddr=10.10.0.1 –lport=21 –caddr=10.10.10.1 –cport=21 –ftp=both
