Comtech EF Data SLM-5650A Vipersat - Manual (Page 32)

Initial Configuration
2-8 Vipersat SLM-5650A User Guide
Choosing Single mode sets the modem to accept all traffic—data, VMS,
and management—that utilizes the Traffic IP Address of the Network
Processor card for this modem. The Management IP Address is ignored.
Selecting Dual mode requires that data and VMS traffic be directed to the
Traffic Address, while CLI, WSI, and SNMP communications must utilize
the Management Address of the NP card. This provides additional security
for remote connections.
Note that Dual mode is also utilized when operating in a redundant
configuration; both the online modem and the offline modem must be set
for Dual IP Addressing. For more information on using the SLM-5650A in
redundancy configurations, refer to the pertinent redundancy switch
Installation and Operation Manual.
Caution: When setting Dual mode, note the address change as the setting will
drop communications to the management interface after submittal.
3. Enter the designated Traffic IP Address and Subnet Mask for this unit.
4. If Dual Mode is being used, enter the designated Management IP
Address and Subnet Mask for this unit.
5. Click on the Submit button
6. Save the settings to flash by selecting Save from the Main Menu bar.

Routing in a Vipersat Network
SLM-5650A Modem Routers operating in Vipersat mode do not use the HDLC
Addressing as described in the SLM-5650A Installation and Operation Manual.
Because satellite networks are often used as extensions for access to services
such as the Internet or the PSTN, they lend themselves quite readily to private
addressing. For example, to provide Internet access to the satellite network, only
the Hub requires a public IP address in order for the entire satellite network that
is controlled by the Hub to have access to the Internet backbone. Utilizing
Network Address Translation (NAT), the administrator can effectively address
the network using a minimum number of static route statements.
