Say I have a
client. I need to create connection from
client to a
server like it was proxy.
Is it possible to do this using a SSH tunel, or do I have to install some proxy service to the

You can do this using ssh
ssh -L 80:remotehost:80 user@myserver
You will have a tunnel from your local port 80 to the remotehost port 80 then. This does not have to be the same as myserver. To make that transparent you should add an entry to the hosts file. If you don't do that vhosts will not work. If you want a SOCKS-proxy connection you could also use
ssh -D 5000 user@myserver
This will create a SOCKS-proxy on localhost port 5000 which routes all requests through myserver.
sshuttle works like an VPN but over SSH.
Transparent proxy server that works as a poor man's VPN. Forwards over ssh. Doesn't require admin. Works with Linux and MacOS. Supports DNS tunneling.
Putty does this pretty well too.
Under SSH, goto Tunnels. At the bottom, put 8080 in the port, and for destination, leave it black and select the "Dynamic" radio button. Thats all you need to do, now connect to the server using Putty.
Once connected, you have a proxy server running on your localhost at port 8080 which will proxy all requests thru your server.
Now use a web browser and setup the proxy by setting host=localhost and port=8080 and make sure its a SOCKS proxy that you select. I do this all the time, so If you use Firefox, make sure to install the FoxyProxy plugin since it makes turning the proxy on/off a one click affair.
Caution: Be aware that by default, you'r DNS requests are not proxied. So the website that you visit via the proxy will still be logged (if they log this stuff). You can set firefox to proxy DNS requests as well, it just doesnt do it by default.
To allow a proxy to be run a computer, and allow other clients to connect to you will need the -g option. So for example, you would run this on the server named foo:
ssh -g -ND 9191 root@remotehost
You can then set the proxy in the browser of a client to use server foo and port 9191 for a SOCKS proxy. The clients will send their requests too foo, who in turn will forward the request through ssh to remotehost. So on the internet, it will look like they are using remotehost.
If you want to forward DNS requests as well with firefox, edit the about:config in firefox and set network.proxy.socks_remote_dns to true.
You can use SSHUTTLE, heres a tutorial on how to use it,
heres a tutorial how to set it up to work as a service,
