Yes, the local firewall is a transparent proxy using a special port which is filtered at head office. As the local offices are international I was reluctant to employ SSL technology because of the associated import/export restrictions. Also, I'm not sure why you emphasise not to use Apache. A VPN would be nice, but some of the connectivity will be via limited bandwidth satellite connections, so I do not see this as a way forward.
