Reverse example

[sohrabp72]

Whether I'm confused or lack of clear docs, this is the scenario:
my PC is behind a restricted network and I have 2 VPS publicly exposed to the internet.
PC can access VPS A, not B.
PC should access services on B.
Accessing A to B is restricted through the firewall, so reverse is needed.
How to configure the chisel between A and B to start a reverse tunnel from B to A to expose a UDP port on B from A VPS
my PC connects to a UDP port on A.
B is connected to A in a reverse mode.
Received UDP packet on A should be delivered to a UDP port on B.
B should send a TCP SYN packet to A. A can't be the initiator of the TCP connection.
