= Setup networking via a PPP tunnel =

This is a simple howto to avoid having to make bridge devices just for IP-based bidirectional connectivity.

Host-OS: debian linux
i{{{apt-get install ppp netcat}}}

VBox-OS: debian linux
{{{apt-get install ppp netcat}}}

Host-OS:
{{{pppd noauth local lock nodefaultroute persist debug nodetach 10.1.2.3:10.4.5.6 pty "netcat -l -p 3042"}}}

VBox-OS: (run this quick, before the previous pppd command on Host-OS gives a timeout)
{{{pppd noauth local lock nodefaultroute persist debug nodetach passive pty "netcat 200.200.200.200 3042"}}}

where 200.200.200.200 is the real IP of the Host-OS

Now, Host IP is 10.1.2.3 and VBox IP is 10.4.5.6 and you can access all udp/tcp ports from one to another
