Your question is not topical because it is not about administering systems in a business environment - that is what your IT department does. Your question would likely be on topic for U&L or SU. However I wouldn't not to migrate it because quite frankly it's crappy and we try hard not to migrate crap.

Why is it crappy? 

- It doesn't provide sufficient information about the environment, we're lead to believe there is a proxy server and a hub. What??? Who uses hubs these days? What kind of access do you want? What kind of proxy server is it ?

- This is your playground too - that sounds very professional don't you mean lab ?

- You suggest that  _... somehow need to set up some sort of forwarding..._ Well, did you try researching that ? Did you try anything ? Or did you just type some crap into a box on Stackexchange ?
