Hello,

can somebody provide me idea how to solve problem:
I would like to make connection between Work PC and Home PC.
Only working solution for me was using Teamviewer but I don't like it and its not open source.

Here is a situation.

Work PC(full access) -> Proxy(no access to change something) -> Internet(only 80,443 traffic)
Home PC(full access) -> Router(full access) -> NAT(ISP, no access to change something) -> Internet(no restrictions)

Its probably impossible to connect these 2 computers directly because no access to ISP NAT and unknown restrictions at company policy including only 80,443 ports are open and no ICMP and so.

But I have 3rd computer(server) which should be as median because it has no restrictions, full access and reachable from internet.

So I thought best solution should look like:

Home PC <-> Server <-only 80,443-> Work PC

Work PC have to connect somehow on Server using only 80 or 443 http/https traffic via company proxy
Home PC have to connect somehow on Server, no restrictions
Server should exchange traffic between Home PC and Work PC.

Ok that's theory, can somebody give me hint from technical side please?

Thank you

check out the links in my sig. if your 3rd computer is a Linux box, then you can use reverse ssh to create a tunnel between your home and the work computer via the 3rd computer.

Hello

Thank you, yes it should work like that.
But what about restrictions that work computer can use only http/https traffic via proxy?
sshd deamon have to run on port 443 on server or is there another solution?

Thank you.

if you are unable to ssh out, then you are fubar. i do not know a way around that issue sorry. there might be a solution out there, but i dont know it yet.
