Sorry if my question is trivial or stupid, I am missing the right network-related vocabulary to make use of google. So maybe you can give me a head start about where to look.
Here is what I like to accomplish: I want a pi in my home network, that can be reached from the "internet" at work. There access to webmailers is blocked, so I thought I can use the pi to tunnel requests from work to gmx and back for example.
Is that possible, what software would I use and is it possible to make it "sort of" secure, knowing that absolute security does not exist?
Any idea is welcome, thank you for your time and patience, Stefan
