Hi, This may be an obvious question but I thought I ''d ask anyway . I have a three-interfaces setup. I want to run some montoring scripts on my firewall and have those mailed to my mailserver in the DMZ. What I''m wondering is how to set this up. I have sendmail on it which I can setup with a smart host relay which is the mailserver in the DMZ. To what NIC interface on the firewall do I assign a hostname and domainname to be used for setting up sendmail. Meaning the ip-address that will associate with that hostname. Does it make sense to do this in the first place anyway ? thanks, Peter
