Thanks David!! I have a static IP. Last year I configured an old laptop with a private IP running LAMP + BIND + Postfix + Dovecot and used port forwarding. After this discussion I'm thinking I need a router capable of routing multiple IPs that would replace my consumer grade router.... however it is not fully clear to me. Thanks for your help!!
