Port-Forward Firewall Configuration
When placed behind a port-forwarding firewall, the Customer Collaboration Platform server is only reachable (for some users) by going through a specific port on a specific machine. All traffic on that port is forwarded to Customer Collaboration Platform, and there is no alteration of the user's request as it traverses the firewall.
Any port may be chosen through which to forward traffic. Typically this would be port 80 or 443 (for http and https respectively), but there are no restrictions. For a port intended to forward non-SSL (http) traffic, the destination should be port 80 on the Customer Collaboration Platform server. SSL (https) traffic should be forwarded to port 443.
There is no additional configuration required on the Customer Collaboration Platform server.
