사설(회사,학교) 방화벽 하에서 원격 허용

학교로 들어오는 포트들을 다 막았기 때문에

밖(집)에서 학교 컴퓨터로 접속하지 못한다.

그러나 반대로 학교에서 나가는 포트는 막아 놓지 않았기 때문에 꼼수를 사용할 수 있다.

Even if you want to connect your office PC outsideof your office, but you can't because of your office firewall.

Then you can try this.

1. install "freesshd" 

http://www.freesshd.com/

2. add user (in house PC)

Users -> add user -> check "Shell, Tunneling"

Tunneling -> check 'Allow local, remote port forwarding'

3. make tunnel to house (in office PC)

I am using Xshell, you may use putty.

○ new section

- connection

- host : _houseip

- port : set in freessshd ssh port(22)

- connection - ssh -tunneling

- type : remote

- source : _houseip

- listening port : _anyport100

- host : localhost

- destination port : _destport3389

then, you can check forwarding is established (opened).

4. move into tunnel (in house PC)

connect remote desktop to 'localhost:_anyport100'

It will be connect 

house:_anyport100 -> ssh tunnel -> office:_destport3389
