I've looked into your first patch. The idea is good however patch has
some problems:
1) Don't hardcode array sizes. Use sizeof ("XXX.XXX.XXX.XXX") instead
2) Exporting variables shouldn't require user to run a command. Just
export them as soon as possible (e.g. on module load)
3) "your_ip" is problematic name. I would prefer "local_ip" and "remote_ip"
