portforwarding - How SSH forward HTTP request to backend server? -

-

we have 3 machine, say, a, may laptop, b, jump machine, , c web server. jump server can access public network without limitations, web server c limited, , only port 22 (ssh service) opened b, , can talk dual-direction via ssh.

we want deploy web server on c, bind port 7788, can configure b forward following request c on port 7788, , without configure c?

curl b.ip:7788

it doesn't require special configuration on b, except port forwarding must allowed (allowtcpforwarding).

on a,

$ ssh -l17788:c.ip:7788 b.ip

then on a, browse to

http://localhost:17788/

there's nothing special 17788, can use free localhost port on a. add 10000 tunnelled destination port keep simple , easy remember.
