I would like to set up RDS for a client so they can access RDWeb easily by simply typing subdomain.domain.com instead of typing https://subdomain.domain.com/rdweb. I accomplished this by:
1. Setting up 301 redirect for all traffic to https://subdomain.domain.com/rdweb
2. Opened port 80
I know that opening port 80 is a general no no but given that all traffic is redirected to one SSL site, my thought is that it would minimise the risk. Both ports 443 and 80 are NATed to the RDS box from a firewall.
Is opening port 80 to my RDS box secure in this case?
