Force in-band filetransfer in Spark?

Hi,

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?

Cheers

Torsten

Please use the 2.7.0 beta of Spark. The negotiation mechanism in that edition have been enhanced and should find the right way, in your case IBB.
