I have extesive experience in firewall and iptables.. I can solve your issue

Dear Sir, My name is Mohammed Al samman, I'm a software engineer with more than 3 years of experience mainly in linux development and administration, although i am new to online freelanceing. Related experience: -developed linux firewall based on netfilter framework with command line interface in userspace by using netlink socket as (IPC) interprocess communication to send data from userspace to kernelspace. -deep knowledge with the standard Linux Kernel networking subsystem including Netfilter packet flow control. -good experiance of kernel socket programming. -developed a kernel module to monitor power supply electrical current status (AC/DC) by using linux kernel notifier. I believe i can deliver the kernel module needed and i do recommend to the firewall approach; as in kernel space we can do deeper packet inspection; DPI; like for example we may allow firefox to access facebook login page only, while allowing other process like chrome full access to all of the site; etc. So it would greatly depend on your app, I can do both approaches; but the kernel module of couse have more fine grained control. looking forward to discuss the requirements a little more; Mohammed Al-Samman.
