This question is directed to Plesk for Windows 7.5.4, however, I have a similar problem with Plesk for Linux 7.5.4. I want to know 'a simple way' to change port 8443 to something else that will work behind a corporate firewall. Just so that you know why some of my customers have strict firewall policies which only allows port 80 and port 443 traffic. There is no way in hell that there administrators are going to allow port 8443 in. The irony is that I asked this question over a year ago when I was evaluating Plesk. This seemed to be a shortcoming of the product, and no-one could really give me a strait answer. Now this problem has come back to haunt me because some of my busiest and most important customers are behind corporate firewalls and they are demanding a lot of support that could have been handled by strait access to the admin control panel. Interessting it appears that Plesk for Linux has a FAQ entry about this on their site, which simply states: "Plesk control panel port can be changed in /usr/local/psa/admin/conf/httpsd.conf with "Listen" directive. For example: Listen 8445 Restart Plesk after change will have been made." However, does this mean I can just change it to 443? Is this also applicable to Plesk for Windows? Strait answers please!
