Transparent proxy server that works as a poor man's VPN. Forwards over ssh. Doesn't require admin. Works with Linux and MacOS. Supports DNS tunneling.

Previously, it was possible to run sshuttle locally without using ssh and connecting to a remote server. In this configuration, traffic was redirected to the sshuttle server running on the localhost. However, the firewall needed to distinguish between traffic leaving the sshuttle server and traffic that originated from the machine that still needed to be routed through the sshuttle server. The TTL of the packets leaving the sshuttle server were manipulated to indicate to the firewall what should happen. The TTL was adjusted for all packets leaving the sshuttle server (even if it wasn't necessary because the server and client were running on different machines). Changing the TTL caused trouble and some machines, and the --ttl option was added as a workaround to change how the TTL was set for traffic leaving sshuttle. All of this added complexity to the code for a feature (running the server on localhost) that is likely only used for testing and rarely used by others. This commit updates the associated documentation, but doesn't fully fix the ipfw method since I am unable to test that. This change will also make sshuttle fail to work if -r is used to specify a localhost. Pull request #610 partially addresses that issue. For example, see: #240, #490, #660, #606. |

sshuttle: where transparent proxy meets VPN meets ssh
=====================================================
As far as I know, sshuttle is the only program that solves the following
common case:
- Your client machine (or router) is Linux, FreeBSD, or MacOS.
- You have access to a remote network via ssh.
- You don't necessarily have admin access on the remote network.
- The remote network has no VPN, or only stupid/complex VPN
protocols (IPsec, PPTP, etc). Or maybe you *are* the
admin and you just got frustrated with the awful state of
VPN tools.
- You don't want to create an ssh port forward for every
single host/port on the remote network.
- You hate openssh's port forwarding because it's randomly
slow and/or stupid.
- You can't use openssh's PermitTunnel feature because
it's disabled by default on openssh servers; plus it does
TCP-over-TCP, which has `terrible performance`_.
