Hi, I am a master student, and currently my school laboratory is developing a router for linux embedded systems. In the router, I used iptables as my firewall setting, and triggered the iptables service in the form of command line through a program written by myself. I did not modify any source code of iptables, and used it by using "/sbin/iptables". If, I want my router to be published as a product, but at the same time, I don’t want to disclose the source code of the program I wrote, so will my program violate the license?
