I have an installation of OpenERP with Nginx as reverse proxy with a certificate SSL generated by me. To access OpenERP, normally you have to enter the path: http:// ip_server:8069, then I use the Nginx to redirect to a domain without having to put the port so it is more comfortable for users to access the OpenERP. In OpenERP I have installed a module for PayPal payments for the ecommerce module.by ioang19 - Other discussion
