Secure RDP connection through Vyatta using PuTTY

Connecting to SSH Server as gateway instead of directly RDP to a PC is safer way and add another layer of encryption.With this method,we can connect to any client that is behind the firewall provided that we have open the port 22 (or any other SSH port) to the SSH Server.

In First step, we’ll configure the vyatta, so that it will forward the ssh request to the internal Linux server that it will receive on it’s port 222.

(From the Configuration Mode, issue these commands)

set nat destination rule 110 description "SSH to internal Host"
set nat destination rule 110 inbound-interface eth0
set nat destination rule 110 protocol tcp
set nat destination rule 110 translation address 192.168.80.102
set nat destination rule 110 translation port 22
set nat destination rule 110 destination port 222
set nat destination rule 110 destination address X.X.X.X
