Here is my -vL outputĬhain INPUT (policy DROP 0 packets, 0 bytes) i have tried various rules but they either seem to open port for any external source or block everything. I m trying to open ports 50 (udp & tcp) for a specific internal ip (192.168.1.5) but i only want communication over these ports to be between specific external host(s) and deny everything else to this internal IP.
