Updated ics-openvpn to last rev 14 Nov 2014.
Material design!
It still doesn't run properly on my tablet, openvpn keeps getting down
and exiting.

You can't simply add a route -to the remote network, becaues that will cause the VPN traffic to also try -to run over the VPN, and breaks the VPN. - -These scripts use the Linux "fwmark" iptables rules to specify routing -based not only on IP address, but also by port and protocol. This allows -you to effectively say "if the packet is to this IP address on this port -using this protocol, then use the normal default gateway, otherwise use the -VPN gateway. - -This is set up on the client VPN system, not the VPN server. These scripts -also set up all ICMP echo-responses to run across the VPN. You can -comment the lines in the scripts to disable this, but I find this useful -at coffee shops which have networks that block ICMP. - -To configure this, you need to set up these scripts as your up and down -scripts in the config file. You will need to set these values in the -config file: - - up /etc/openvpn/fwmarkroute.up - down /etc/openvpn/fwmarkroute.down - up-restart - up-delay - - setenv remote_netmask_bits 24 - -Note: For this to work, you can't set the "user" or "group" config options, -because then the scripts will not run as root. - -The last setting allows you to control the size of the network the remote -system is on. The remote end has to be set up to route, probably with -masquerading or NAT.
