Dear sirs,
I have a standard firewall, almost minimal linux
installation+netfilter+3 interfaces (internal, external and perimeter)
I want to redirect all POP3 requests back to my main server. POP3
requests from the main server is forwarded to the internet.
Something like this.
------------ -------------------
! ! ! !
! Client !--------->! router/firewall !
! ! ----! !
------------ ! ->! - - - - - - - - ! ---->(Internet)
! ! ! !
! ! -------------------
------------- ! !
! !<----- !
! Server !--------

I can scan all pop3 traffic for viruses by this method.
I believe this setup would be correct for proxying other protocols to.
I would preferably be interested in also being able to redirect the
protocol port too.
Is it possible to do this with the current netfilter release?
I am aware that there is good chance of unwanted loops with this setup
regards,
Magnus Sundberg
