Port Forwarding

Remote Port Forwarding:

Local Port Forwarding:

Installation

$ pip install portfly

Usage

On server side, you need to setup portfly to listen, even for udp forwarding path:

$ python -m portfly -s server_listen_ip:port

On client side, you control all the details:

# remote forwarding by tcp is the default
$ python -m portfly -c [-x] [--log {INFO|DEBUG} <settings>
# local forwarding by tcp:
$ python -m portfly -c -L <settings>
# local forwarding by udp:
$ python -m portfly -c -L -u <udpport> <settings>
# remote forwarding by udp:
$ python -m portfly -u <udpport> <settings>

The <settings> part is just like ssh, which is:

mapping_port:target_ip:target_port+server_ip:target_port

The extra + can leave the whole parameters unquoted.

Each client process can map only one port to/from server. But server can be connected by many clients simultaneously.
