What is the best way to create remote tunnel?

Question

I have 3 Linux servers:
- 10.0.0.0/24 - (10.0.0.10) Linux server inside my LAN.
- 20.0.0.0/24 - (20.0.0.10) Linux server with HTTP Apache server
- 50.50.50.50/32 - Server on Amazon AWS which see both 10.x and 20.x LANs.

10.x cannot see 20.x and 20.x cannot see 10.x
What is the best way (and how can I do it) to se 50.50.50.50 server on AWS to create tunnel from 10.x to 20.x

For example, if 20.x runs HTTPd, I want to be able to go to 50.50.50.50:80 from 10.x servers and see 20.x:80 content .

Thanks.

Answer 1

Login to 50.50.50.50 and run

ssh -L 50.50.50.50:80:20.x:80 [email protected]

and enter your password for [email protected].

Now, if you connect to 50.50.50.50:80 from 10.x you should see the HTTPd on 20.x.

You can add a -N to not execute a remote command. Add a -f -N to background the ssh process.

cheers,
