Dual Ethernet ports The HN7700S has two RJ-45, 10/100BaseT Ethernet ports. The

•
Hughes serial appliance, which can support up to four serial
devices
•

Ethernet port configurations The Ethernet ports support the following configurations:
•
Dual port, single subnet:
Only one Ethernet port is configured with an IP address at the
NOC, which means the terminal supports one subnet.
•
Dual port, independent subnet:
Each Ethernet port is configured with a separate IP address at
the NOC, which means the terminal supports independent
subnets.
Port forwarding
The port forwarding feature allows a user to configure the
HN7700S to forward specific TCP and UDP traffic from the
Internet to servers on a LAN. For details, see
Port Forwarding
Configuration page on page 30.
