Advanced firewall
Advanced Firewalling is applied when servers are connected to Combell's redundant firewall infrastructure (hardware firewall cluster). The firewall will be simulated on the Customer's server, based on the software settings (software firewall). During the initial setup, Combell determines the configuration of this software firewall (Linux web server/database server or Windows web server/database server...). Traffic via the following ports is allowed: POP3 (110), SMTP (25), HTTP (80), FTP (21), Remote Desktop (3389), Plesk (8843), MySQL (3306) and MS SQL (1433). By default, not all ports are open. Upon the Customer's request via e-mail, traffic via some of the abovementioned ports can be authorized.
The Customer is free to have changes made in the configuration without extra cost, provided that he can explain why he wants these ports to be open. However, Combell always reserves the right to refuse making such changes. To do this, the Customer must always contact Combell. A maximum of fifty firewall rules (objects) can be set per server.
