We have the problem, that the filetransfer between clients behind a NAT-Device have problems sending/receiving files from a client behind another NAT-Device. So we want to force the in-band bytestream transfer for the clients. We found this option in psi+ and it worked.
But how can I set this option in Spark ? We want to route all traffic over the openfire server to avoid any communication issues.
Is there a way to force this communication way?
