Testing, testing, testing PLEASE!

Dear List!

Code is freezed for testing now. Please be aware that this code will eat your dog and burn your house! Please test it in a nonproductive environment and tell me what you find.

This is essential for my ongoing project to implement a "vpn-Firewall WUI".

Any feedback (as always) is greatly appreciated. I don't expect any errors but i like you to have another pair of eyes on the code.

Thank you!
