21 Linkstar iwant own network between them

Linkstar terminals are for internet access service using small customer VSATs via a large teleport such as at Skylogic, Italy.   To activate the sites contact a reseller listed for  satellite internet access in the middle east.   If you need to transfer data between sites check that it is allowed and technically feasible.  If you want VoIP, ask.  VoIP calls between sites would suffer a double hop delay.  Special configuration at the hub may be necessary, so verify feasibility with the service provider.  The IP addressing would form part of the Skylogic private IP address space so you would not have a VPN.

If you really want to establish your own network, consider becoming an iDirect VNO, where you buy 1/5th of an 5-IF Hub at a teleport.  All sites will need iDirect modems.

If you want mesh voice call networking with single hop calls between sites, this can be done, using larger dishes and new modems, for example Vipersat, but, as with iDirect VNO, considerable investment is needed in learning network management and configuration plus the all new equipment, software licence and hub costs.

With either iDirect or Vipersat you could have your own private IP address range and so would have a private network (PN) and not need any Virtual encapsulation (VPN).
