Dear Oliver Fromme,

Thanks for your input. I really appreciate it. I have rechecked my
firewall and I do have the following rule:

$IPFW add fwd 127.0.0.1,3128 tcp from any to any 80 in


I have place your rule on top of the above rules like this:

ipfw -q allow tcp from 192.168.55.22 to www.hotmail.com
ipfw -a add fwd 127.0.0.1,3128 tcp from any to any 80 in
ipfw -q add allow tcp  from 192.168.55.0/24 to any  3128 in via bge0

Are the above rules correct ?


Once again, thanks alot.
