How can I use FreeBSD to receive incoming connections instead of router?

[Ricky]

Hi, I'm wondering how can I make incoming connections going to my FreeBSD server and then my router?

Basically this:

I want to use FreeBSD's firewall to check everything coming instead of my router's firewall.

Be sure to that you use correct references to your NIC

AS long as the router is an independent unit (IE; not part of the ISP modem like what ATT provides its customers) you can configure the router to turn off the automatic NAT function and cable it to function as a switch then the install guide here http://www.a1poweruser.com will give the step by step details you need. Use ipfilter (IPF)firewall which is included in the basic Freebsd release.
