Hello to all! What I want to do: Hiding a M$-Exchange-server behind a Debian-based firewall running ipchains (with masqerading) and squid and ???. Here is my special problem.
What is the configuration: Through an old little Cisco 1003 router the connection to internet is done. Then I run a Debian-Box with 2 interfaces. One for the DMZ and one for internal net. In the internal net users are served by exchanger-server. What I tried: Using sendmail as MTA to do the transfer between the DMZ and internal net. It was driving me creazy with all his antirelaying stuff. This can be a problem of just not understanding the matters. I've running in an other environment sendmail with virtual users and masquerading of domains, serving several users through IMPA-server, but as an endpoint in the transfer-chain. So some very basic understanding I have how to handle sendmail. What do I need: 1. I don't know what software I should run on the firewall to catch all incoming smtp-traffic and deliver it to the internal net -> Exchange-server and vice versa. The exchange server understands only smtp. 2. In which way should it be done ? Installing an MTA (which one?)on the Debian-box or to transfer all traffic directly to the internal net by forwarding(how to do this ?). Please can you give me some hints in which direction I should investigate ? I'm shure some of you have solved this problem already.
