port issue

Hi, I am setting up a new ecommerce site in South Korea using wordpress, and I was choosing between different security options, many people recommended Sucuri firewall so I bought it and set it up on my site, and made a DNS change so the site points to the cloudproxy and then to my host. Then, I had to install a SSL certificate so I installed it both in my host and at sucuri. The SSL does not work properly and people from my hosting provider in South Korea say, the https requests from sucuri use 443 port, but they do not support 443, they opened a new port for me. That is possibly why SSL does not work. Sucuri supporters say they’ve never heard of any single or shared hosting providers that cannot use 443 port, but I’ve made a few phone calls and found out that it really is the case here. No major hosting providers here use 443 or 80 for shared hosting.

I am saying this here to ask if I will have similar problems using the ithemes pro version. Thank you.
