ssh, as long as that server has python 3.6 or higher.

.. option:: <subnets>
A list of subnets to route over the VPN, in the form
``a.b.c.d[/width][port[-port]]``. Valid examples are 1.2.3.4 (a
single IP address), 1.2.3.4/32 (equivalent to 1.2.3.4),
1.2.3.0/24 (a 24-bit subnet, ie. with a 255.255.255.0
netmask), and 0/0 ('just route everything through the
VPN'). Any of the previous examples are also valid if you append
a port or a port range, so 1.2.3.4:8000 will only tunnel traffic
that has as the destination port 8000 of 1.2.3.4 and
1.2.3.0/24:8000-9000 will tunnel traffic going to any port between
8000 and 9000 (inclusive) for all IPs in the 1.2.3.0/24 subnet.
A hostname can be provided instead of an IP address. If the
hostname resolves to multiple IPs, all of the IPs are included.
If a width is provided with a hostname that the width is applied
to all of the hostnames IPs (if they are all either IPv4 or IPv6).
Widths cannot be supplied to hostnames that resolve to both IPv4
and IPv6. Valid examples are example.com, example.com:8000,
example.com/24, example.com/24:8000 and example.com:8000-9000.
``a.b.c.d[/width][port[-port]]``. Valid examples are 1.2.3.4 (a

1.2.3.0/24 (a 24-bit subnet, ie. with a 255.255.255.0 netmask).
Specify subnets 0/0 to match all IPv4 addresses and ::/0 to match
all IPv6 addresses. Any of the previous examples are also valid if
you append a port or a port range, so 1.2.3.4:8000 will only
tunnel traffic that has as the destination port 8000 of 1.2.3.4

Examples
--------
Test locally by proxying all local connections, without using ssh::
$ sshuttle -v 0/0
Use the following command to route all IPv4 TCP traffic through remote
(-r) host example.com (and possibly other traffic too, depending on
the selected --method). The 0/0 subnet, short for 0.0.0.0/0, matches
all IPv4 addresses. The ::/0 subnet, matching all IPv6 addresses could
be added to the example. We also exclude (-x) example.com:22 so that
we can establish ssh connections from our local machine to the remote
host without them being routed through sshuttle. Excluding the remote
host may be necessary on some machines for sshuttle to work properly.
Press Ctrl+C to exit. To also route DNS queries through sshuttle, try
adding --dns. Add or remove -v options to see more or less
information::

- Use the :option:`sshuttle -r` parameter to specify a remote server.
One some systems, you may also need to use the :option:`sshuttle -x`
parameter to exclude sshserver or sshserver:22 so that your local
machine can communicate directly to sshserver without it being
redirected by sshuttle.
- By default sshuttle will automatically choose a method to use. Override with
