I was recently trying to play some old game (Starcraft, Warcraft 3, and others) in LAN with some friends through the hamachi VPN system. All attempts were unsucessful due to the fact that the broadcasted UDP packet weren’t sent over the VPN interface but only in the local LAN.
To solve this we just had to manipulate the routing table of the systems.
After connecting to the hamachi VPN just do these commands as root user
OS X: as long hamachi uses 5.x.x.x for his nodes
route add -net 255.255.255.255 18.104.22.168
Linux: where ham0 is the hamachi interface. There are 2 options available, test it out that works for you
route add -net 255.255.255.255 netmask 255.255.255.255 dev ham0
sudo route add -n 22.214.171.124 gw 126.96.36.199 dev ham0
as suggested from Blake Lightly
This will redirect all the broadcast packets, maybe it can interfere with some other program, but as long as you want some time off to play it works great. To clear the modification to the routing table we didn’t do anything else then disconnecting from the hamachi VPN, the system handles the disappareance of the interface removing every involved route.
* Linux has no other setup then just starting hamachi. This all was tested between a Mac and a Linux systems
If someone can test other games and maybe help on the linux problem that would be great.
Hope this helps!

Me and alka wrote a web application in ruby which serves as an interface to rtorrent. It has been written in ruby using the ramaze and sequel frameworks. It
is currently tested on debian stable with mostly apt-get installed gems,
for more info check the README file included (the only one external to
the distribution should be the xmlrpc gem which is on another post in
It supports authentication and accesses rtorrent through the unix socket
interface, allowing to run the server as a user process.
An internal copy of the information from rtorrent is stored in a
in-memory sqlite database (maybe it can be totaly avoided, but that was how we planned it in the beggining) to avoid to access too much times to rtorrent
along with the caching of pages in ramaze.
Currently may lack some feature, but it’s doing it’s job, the main
missing feature is the user interface. If someone can write a
CSS and maybe do some cleanup in the interface any help would be
As usual in the code page everything can be found or directly here
It is currently no more developed as we switched torrent client. Patches or comment are welcomed
