ZPRD is a simple, unencrypted IPv4 tunnel tool, which is a server and can be a client.
The ZPRD was created to tunnel through complex routing setups with firewalls, NATs and VPNs.
-
The ZPRD establishes peer connections at startup.
-
The ZPRD manages incomming connections.
-
The ZPRD doesn't encrypt any data, as it is designed to have very less overhead. It is intended to be used in combination with VPN software.
-
The ZPRD ONLY tunnels IPv4 (and IPv6 experimental) packets over UDP and IPv4/IPv6.
- protocol stacking:
ethernet > ipv4/6 > udp > ipv4 > payload
- protocol stacking:
- compile zprd / installation
mkdir -p build && cd build
cmake .. && make -j3 && make install
- setup /etc/zprd.conf (content; initial)
Itun3
- setup interface (this is usually done by the daemontools)
ip tuntap add mode tun user ... tun3
- start zprd (this is usually done by the daemontools)
./zprd
- fetch the portage overlay
cd /usr
git clone https://github.com/zserik/portage-zscheile

emerge the package with:
emerge -av =net-misc/zprd-9999 -
