On scanning my public IP address I noticed that port 443 was open using port forwarding. This is obviously for owa and remote workplace etc but I was wondering if there was a way I could secure it more.
Is there away that I could say by a domain name say remote.com and then have a forwarder setup with my hosting company to my public IP address. I then could make a rule to only accept ip traffic from 1 ip address ie my hosting company and block all other access from all other traffic? I have setup my firewall to report of any DOS attacks etc and I am getting loads of them and want to make my business more secure.
