How can I implement the following scenarios:

1) Allow all Intranet users to have access to the web
site using custom security (I don't want the local
Intranet users to login to the application. I can get
their user identity and apply custom roles)
2) Have Internet users be authenticated using
FormsAuthentication over SSL to the same site.

Can anybody got any ideas please?
