[MonoDevelop] [HowTo] Executing Shell Commands...

[Quandary]

proc.StartInfo.FileName = "/sbin/iptables";

You should also try to read back the process exit code, such as 
EXIT_SUCCESS or EXIT_FAILURE.
To do it on bash: echo $?

If that won't work with system.diagnostics.process, you can try to 
DllImport popen from glibc

    #include <stdio.h>

        FILE *popen(const char *command, const char *type);

        int pclose(FILE *stream);

You can get a reference on how to use popen to read results from 
programs, such as a GDB disassembly from one of my aimbots here:

If you have too much time, you can also read the source of iptables and 
implement a netfilter API for Linux in C#, that is to say, writing your 
own firewall.

You can also try to use libiptc:
