I use putty for configure my routers and some time for ssh tunnels for access to home network.
However putty need reconnect every time. MyEnTunnel can reconnect automatically and make your life easy. You can setup a lot of ports.
For example for 3 RD for home network:
3310:192.168.1.10:3389
3311:192.168.1.11:3389
3312:192.168.1.12:3389
MyEnTunnel is free and you can download it from http://nemesis2.qx.net/pages/MyEnTunnel
