DSL Modem to Linksys Router using Static IP Address

[Pintoo160581]

My ISP is TATA BroadbandVSNL and they assign to us a one Static IP address.
Now, i have taken one domain from no-ip and assign that static ip to that hosts.
My connection is working like this way
DSL Modem (TATA Broadband VSNL) ==> Linksys Router (Basic Setup is on Static IP and DHCP is Enabled) with WAN Port ==> Cable goes to Switch (16 X 16 Port and Every Workstations and Servers are connecting from this Switch) ==> Server1 (Domain Server for LAN) and workstations.

Can anybody help me out that on this situation, how may i connect to that Hosts using remote desktop connection?
