Setup networking via a PPP tunnel

Contributed by Pedro Zorzenon Neto, 2008/04/09

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

Host-OS: debian linux

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, for the guest the host IP is 10.1.2.3, and for the host the guest IP is 10.4.5.6 and you can access all udp/tcp ports from one to another.
