HughesNet Basic Service (Residential) plan is not compatible with VPNs.
I sometimes use a NordVPN (or Bitdefender's) with HughesNet, but experienced reduced speeds as much as 75 - 90%. You can restore your connection to full speed by simply disabling your VPN client when your session is over.
HughesNet uses sophisticated acceleration techniques to enable high-speed performance over a satellite 23 thousand miles above the earth, a 46-thousand mile roundtrip. These acceleration techniques require access to data packet header information, which is blocked when VPNs are used. These VPNs encrypt the data and create a secure tunnel through the HughesNet network. The encrypted data cannot be processed by HughesNet's acceleration techniques, therefore resulting in slower performance. Tech Support told me that a Business Plan may be different, but the price differential was too much. A cheaper solution was to get a wi-fi hotspot from a cellular service company, because cellular has, or you can set, a "VPN passthrough" and then the speed loss is generally less than or up to only ten percent.
