I will set up Clarkconnect community 5 (firewall and SMTP relay on the same machine) for about 150 users with a hardware configuration appropriate recommendations in accordance with Clarkconnect.
I thought to do as follows:
Internet - Firewall and SMTP relay Clarkconnect - Appliance Security Trend Micro AS, AV, Content Filtering - Network LAN
The security appliance is still valid and is installed in "pass through" between CConnection LAN side and the rest of the network (no DMZ in this configuration). The advantage of this appliance is that it will save me from overloading Clarkconnect with SpamAssassin, the AV ...
I want to use the SMTP relay on Clarkconnect because I do not want to translate port 25 on my Domino server that is on the LAN.
My question is:
What do you think of my config? Is DMZ more suitable?
