Proof-of-concept
Setup

Tunnel through SSH
Configure port forwarding using a server with a route already existing on the
PLC. That is, in ~/.ssh/config:
```
Host host_with_route_on_plc
LocalForward 50000 plc_ip:48898
```
Edit and run test.py to intercept ADS requests made to your local machine (port
48898):
```sh
$ python test.py
```
Run an additional ADS client script to tunnel through SSH, fixing up your source
AMS ID without any client-side modifications:
```python
import os
os.environ['DYLD_LIBRARY_PATH'] = '/Users/klauer/docs/Repos/pyads/adslib'
import pyads
# plc_remote_ip = '172.21.148.145' # <-- actual IP
plc_remote_ip = '127.0.0.1' # <-- tunnel
plc_remote_net_id = '172.21.148.145.1.1'
plc = pyads.Connection(plc_remote_net_id, 851, plc_remote_ip)
plc.open()
print(plc.read_device_info())
```
```sh
$ python client.py
