Routing through vpn

[Loïc Grenié]

     Hi,

     I've an up and running tinc vpn between my laptop and my office computer
  (on which I've root access if needs be). From where I'm sitting right now, UDP
  packets are dropped. TcpOnly has solved the problem for the tinc part and
  I can still connect to my office. I'd like to access some important
  <cough>irc</cough> UDP-only services. Do I have a possibility to route
  those UDP packets through tinc ? I've tried to add

SubNet = <destination host>

  in the /etc/tinc/vpn/hosts/office-computer file
  and run a

route add -host <destination host> dev vpn

  on the laptop, but it does not seem to work.

     What should I do ?

     Thanks in advance,

          Loïc
