We have a client with 2x Forms server in the DMZ authenticating through an external STS, which allows internal user to login and access through the Internet while outside of the company's network. The client would also like to purchase Forms portal license to allow public form submission without login. Base on their existing infrastructure, would like to ask if the client can simply purchase 2x Forms portal licenses, upgrade the existing Forms servers and public users can already access and submit forms, while the internal users will still have to login to access any Forms that has not been made public. Thanks
