In case you want to try transparent proxying you need to look into
firewalling.
I can only tell you how this would work with OpebBSD's PF since I use it
myself and quite like it. :-)
Have a look at pf.conf(5), but it should work like this (in /etc/
pf.conf):
+++++++++++++
int_if = "em0"
rdr on $int_if proto tcp from $int_if:network port { 80 } ->
192.168.0.1 port 87
+++++++++++++
In this example you need to specify your network interface as int_if
(in my case it is em0)
If this doesn't suit your situation, you probably need to give us more
information: The
kind of network setup you use (eg internal -> firewall -> external)
and what needs to connect
to and from where. do you have a firewall solution in place (PF,
ipfilter, ipfw)? And what do
you need to achieve?
br & good luck,
Robert
