Fix Bugs in a program

Hi I have a program made in Delphi and C++ What it basically does it redirects all application traffic to a specified IP like for example all browsers traffic will go to our proxy program which is listening at IP [login to view URL] port 2149. At the moment there are bugs that needs to be fixed? At the moment when the software is activated the browser like chrome it crash and need to make it so it also redirects UDP traffic not just TCP. Please be 100% sure you can do it before bidding Many Thanks
