Unfortunately, SSH is a TCP based protocol. RTP is a UDP based protocol
and with good reason - packet loss is fine and expected (Opus has packet
loss concealment and forward error correction, both of which are made
use of for OpenOB). So you need a UDP based tunnel, which basically
means a VPN or something similar.
