Hi,
There is a quotation from sonicwall:
Additionally, granular access controls enable the network administrator to provide not only employees, but also trusted partners and customers with remote access to specific and defined resources. Features include:
Files and file systems (includes support for FTP and Windows Network File Sharing)
Web-based applications
Microsoft Outlook Web access and other Web-enabled applications
HTTP and HTTPS intranets
Same things on cisco site and others.
Or, you can change SSL port forwarding to other, not 443 port.
