I am trying to setup Appgate Ip tunneling driver on my ubuntu 12.04 by following appgate instructions listed below: Installation, Linux Make sure the kernel has support for the Universal TUN/TAP device driver, and then log in as root and create a new directory somewhere, and copy the files ag_iptd add_route add_gw_route add_hosts_entry ag_iptd clean_hosts_file del_route del_gw_route del_hosts_entry interface_down interface_up remove_dns_server set_dns_server fix_localhost into that directory. Then start the IPTD daemon by doing modprobe tun <directory-somewhere>/ag_iptd There is also an init script 'ag_iptd.init' that can be installed to automatically start the IPTD daemon every time the OS is loaded.Please check the documentation of your Linux distribution on howto do this. so is there any way to checkif my ubuntu 12.04 kernel has support for the Universal TUN/TAP device driver? and how to do so? Thanks,
