After setting up an openvpn server on my tomato router using this guide - http://blog.johnso.org/2009/08/how-to-setup-openvpn-in-tomato.html - changing only the port number and protocol from UDP to TCP, I connected my mac to the openvpn. However, I keep getting the error message:
write to TUN/TAP : Input/output error (code=5)
over and over again when I connect. Occurs also when I connect using the plain openvpn console client. It sounds similar to the problem outlined here - http://code.google.com/p/tunnelblick/issues/detail?id=73 .
Is there a workaround for this?
