Public raspberrypi https/mail/dns... on Cox Cable

[techlists at phpcoderusa.com]

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!!
