vpnbypass: No longer depends on hardcoded WAN interface name). vpnbypass: Table ID, IPSET name and FW_MARK as well as FW_MASK can be defined in config file. vpnbypass: Uses iptables, not ip rules for handling local IPs/ranges. vpnbypass: More reliable creation/destruction of VPNBYPASS iptables chain. vpnbypass: Updated Web UI enables/start and stops/disables service. vpnbypass: Beautified output.
