Thanks so much for this program - it has saved my life.
I have two complaints, though. Firstly, it was too hard to find. I only happened to find a link to it as I was browsing the Winpcap site (I had started writing a simpler version of GIT myself - since I didn't know it existed)
I had scoured google for things like "forward broadcast packets" and variations on that theme, but never saw GIT. And since my application isn't gaming, I might have passed it by even if I did. So please try and get it better listed in google so others can find it.
Second, I found the configuration a little difficult at first - the readme is a little confusing and the configuration page makes it seem like you're setting up a client, whereas (I still am not sure) it seems like you have the option to set up a client or a server, depending on whether you choose tcp listen or tcp connect?
I really believe there is a wider demand for this program. I even believe it should forward netbiosIP packets is so asked, so that people with small VPN's can avoid all the workarounds necessary to do SMB networking easily.
