IP forwarding
-------------

Please note: If you want to use pptpd to create host-to-site tunnels
(e.g. typical road-warrior setups), then you will need to enable IP
forwarding. This can be done by un-commenting

    net.ipv4.ip_forward=1

in /etc/sysctl.conf.


Support for non-Linux
---------------------
For the time being, pptpd is restricted to Linux only. Patches to
re-enable support for other platforms are welcome.

Issues on kfreebsd:

* bcrelay does not compile. Workaround: Disable bcrelay
* There's no pppd here but freebsd-ppp instead. Appearently it has a
  completely different parameter usage.

Issues on hurd:

* bcrelay does not compile. Workaround: Disable bcrelay
* No ppp at all.
