Redmine

Hi all, we are trying Redmine 2.1 migrating from Trac. All is going well but we've got stuck in something:

We have our internal Redmine server with several projects. We decided to created another one Redmine server exposed to internet and open for customers to access with credentials and create tickets for us. ¿What is the problem with this? :

The person in charge of deal with this support tickets needs to create sub-tasks of this issues in order to get it resolved, but we can not figure it out if there is a way to create these new ones in our internal server.

As known, Redmine allows cross-project issues in the same server, but not from external ones, unless it would be possible via REST WS.

The schema would be:

• Server 1: many projects, internal use
• Server 2: Project called "Support", Exposed to internet for customers

• Someone opens a ticket in Server 2: Project "Support"
• The person in charge of dealing with these issues takes the ticket and create a sub task or taks in Server 1:Project "Proj1", and another one in Server 1: Project "Proj2"

We need it to get tied and measured how many tasks we needed to fix a support issue.

Any help or idea would be very very helpful !!!
