Tom,
What kind of network setup do you have? I ask this because I kept our server on the private LAN and forwarded some ports from our Cisco router to it.. so only those specific ports were forwarded (pop, web, smtp, etc). Then recently I moved this server to directly connect to our DSL to act as a router, and used the other NIC for the private LAN. -Mark _____ From: Tom Manliclic [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 27, 2008 2:39 PM To: [email protected] Subject: [qmailtoaster] Setting up Internal and External LAN connection with security in QMT I hope somebody will be able to help me with below. I wanted to do these things using the newly installed QMT mail server in CentOS5. I followed the instructions from http://wiki.qmailtoaster.com/index.php/CentOS_5_QmailToaster_Install#Getting _Started web site. * Assign Static IP address (Internet interface) * Assign private IP address ( as a local interface) * block all other services and just allow smtp/pop/web access access coming in from Internet and local interface * and how to verify if configured properly We are a small business and housing our own email server is the best option for us since we need local and Internet accessible mail server. I also, wanted to try to upgrade using QTP but can't find the correct documents to do it. Thank you very much for the support.

I already set it up and it was working properly locally and it can send emails outside too. I have two LAN cards available in the machine but when I first setup the mail server I just assigned one local IP address (because I still don't have the static IP then) and just used existing DNS that we have. Now I have the static IP available and I would need to assign the new IP to the other LAN card (Internet) and allow only incoming smtp/pop connections to the mail server. Can anyone help me get a detailed document or site that can help me understand how to do it, secure it and manage it? I don't want our mail server to be available today and tomorrow it was already hacked. I am using CentOS 5.0 and latest packages of QMT. Thank you for the help. Tom
