A system includes a first MODEM configured to generate a first data packet (including a first virtual routing and forwarding (VRF) instance identifier associated with a first service, a first user group, or both) based on a first radio-frequency (RF) signal and a second MODEM configured to generate a second data packet (including a second VRF instance identifier associated with a second service, a second user group, or both) based on a second RF signal. The system includes a network device configured to receive the first data packet, transmit a first packet (including a first header that includes a first indicator associated with a first VRF instance) to a first device via a network, receive the second data packet, and transmit a second packet (including a second header that includes a second indicator associated with a second VRF instance) to a second device via the network.
