FreeBSD 5.1 DSL:Bellnet HS Network Connection Set-up Problems

Tue Jun 22 11:01:25 PDT 2004

<><><><>NETWORK CONFIG/SETUP: <><><><>

+++ISP -> DSL(high-speed) -> Modem> FreeBSD51 server machine in at Gateway "vr0" (192.168.0.1)

+++Freebsd machine LAN Interface at "ed0" (192.168.0.3) -> HUB

+++HUB> 1) 192.168.0.2 - WinXP #1 machine 2) 192.168.0.3 - Freebsd machine in at "ed0" 3) 192.168.0.4 - Winxp #2 machine

At the moment, I've just got the HUB connected to the freebsdmachine at "ed0" and will connect the others as soon as I get the server online.

<><><><><>The PROBLEM:<><><><>

I cannot get my server connected to the internet through the gateway.  What am I doing wrong?

Some one who was trying to help me earlier mentioned that for a network setup I need the following: in  /usr/local/etc/rc.d/natd.sh !#/bin/sh

sbin/natd -u -m -s -n tun0 -redirect_address 192.168.x.x public_address 

in order for someone to get to my boxes from outside my local network. So I have a file called natd.sh in my system but I have not put in values for -redirect_address or public_address yet as I am not sure what they are suppose to mean.

<>2<>
Someone told me to change rc.firewall but I don't think the set-up it correct. I'm not sure if I should be using "tun0" or "vr0" and I think that my onet and inet are not configured properly ... how should this be configured given my topology?
