Could you please explain a bit more about the echo daemon?
Also to supply a bit more information......Let's say the name of the
firewall is Super. What I did in Super's host table was to call the
internal ip
address of Super, Superport1 and the external ip address Superport2 for
entry in the ISP's domain table. Do you think this will affect anything?
I'm going to ask about this echo daemon thing. Thanks for your help alot
