Standalone client questions

Apologies if this is something I should have found in the documentation, but so far it's eluding me. We have a software package in which our clients assemble data. Some of the data they exchange with a third-party site which uses F5. We set them up with a license for the standalone FirePass VPN client to do so, using FTP through the tunnel, as the 3rd-party site mandates. So far, this has been on stand-alone systems, so there's just one user, and one FirePass VPN session, per system.

 

 

What we're looking to do now is have multiple clients remotely accessing our software on a Citrix cloud where at times more than one client will end up with separate user sessions on the same box. There will be times where more than one client wants to exchange data with the third-party, F5 site. Will this work? Does FirePass standalone install so that multiple users, provided they have the licenses, can each establish their own SSL VPN tunnels simultaneously to a single, third-party, external site?

 

 

If so, are there known gotchas? If not, are there good alternatives?
