Hello Karl,

With most firewalls/routers it is only necessary to setup forwarding for incoming connections. Outgoing connections should already work fine without the need for additional network related configuration.

Unfortunately each firewall or router vendor uses their own configuration system with completely different menu and access system. They don't even agree on how the functionality is called. Some do call it "port forwarding", but others may call it "application sharing" or even "game sharing". This makes it impossible to create a one-size-fits-all guide that can be used by a non-techie to setup port forwarding and troubleshoot connection issues.

Having said that, this should not necessarily be a problem. A studio can setup their routers to accept the incoming connections and give their public IP address and port number to the VOs who they like to do a session with. The VOs can then simply connect to the studio, rather than the other way around. In the end it does not matter that much who makes the connection; there are no call charges related to the IP connections. This means that VOs don't need to do any setup on their own routers and that all the setup is done at the studio end, where it is more likely that there is a technician available.

Best regards,

Edwin.
