fought with this for the past hour...gave up again.
it's my 3rd attempt..this is on a stand-alone debian box with no gui.

I tried the following:

iptables -t nat -I PREROUTING  -d $ETH0IP -p tcp -m tcp --dport 143 -j 
DNAT --to 10.1.3.5:143
iptables -t nat -I PREROUTING  -d $ETH0IP -p tcp -m tcp --dport 80 -j 
DNAT --to 10.1.3.5:80

didn't work so tried:

iptables -t nat -A PREROUTING -d $ETH0IP -p tcp -m tcp --dport 80 -j 
DNAT --to-destination 10.1.3.5
iptables -t nat -A PREROUTING -d $ETH0IP -p tcp -m tcp --dport 143 -j 
DNAT --to-destination 10.1.3.5


am I thinking backwards ?  I copied what I have for my e-mail port 25 to 
be redirected to my email server...and that I know works =)
