Hi,
I need to run multiple instances of OpenVPN server on just one tun device driver (say tun0) all on same subnets. I tried editing the open_tun function in tun.c file, first instance goes well and creates tun0 but when the second one comes along it cannot use tun0 and I get the error "ioctl(TUNSETIFF): Device or resource busy ". I really need this functionality. Please give me some hints. Thanks
