Frequently Asked Questions (FAQ’s)
Q1: I have 6 DSL lines how fast will my Internet connection be?
Lets assume each line is 6Mbps download and 766Kbps upload speeds.
Truffle can operate in 3 modes:
a) When peered over the Internet to another Truffle device that has the VLL server license, Truffle will be enabled with total uplink and downlink speed of the 6 DSL lines, i.e. 36Mbps downlink and 4.6Mbps uplink speed. Please see our VLL (Virtual Leased Line) product from the left menu for further details.
b) Via the optional Broadband Bonding Service subscription, the Truffle will be enabled with the total uplink and downlink speed of the 6 DSL lines, i.e. 36Mbps downlink and 4.6Mbps uplink speed.
c) If Truffle is not peered to another Truffle with VLL server module or does not have the Broadband Bonding Service, then Truffle will operate in standalone mode. In standalone mode all http downlink traffic will be bonded (i.e. file downloads will happen with 36Mbps). For all other types of traffic intelligent load balancing will distribute the traffic on a session by session basis and therefore for a single non-http session or for a single upload session the speed will be limited to one of the DSL lines, i.e. 768Kbps.
Q2) How many LAN interfaces does the Truffle support?
Two. In order to provide aggregated Internet access to more than two local devices, the uplink port of a router or switch can be connected to the Truffle, and the local devices can plug into the router or switch, including a wireless router for wireless access.
Q3) What types of addresses does Truffle support?
Truffle supports DHCP, PPPoE and static IPv4 addresses assigned from your ISP. The Truffle can be configured appropriately through the web-based management interface. In the case of a static address, the LAN port of the Truffle can be connected to a switch, and devices connected to the switch can be publicly addressed from the Internet through their statically assigned IP addresses. By default, however, the Truffle uses DHCP to obtain a dynamic IP address on each Internet access line.
Q4) Does the Truffle support port forwarding?
Yes; port forwarding on the Truffle is configurable through the web-based management interface.
Q5) Is the Truffle designed to be compatible with my existing LAN equipment such as routers, switches and firewalls?
Yes. Any LAN interface on the Truffle simply replaces the Ethernet port on a DSL modem or cable modem, in an existing LAN configuration with only one Internet access line.
Q6) Do I need to order anything special from my ISP to use the Truffle?
No. The Truffle is a stand-alone product that does not require any special software, hardware, or configuration from the ISP(s). All that is required is the acquisition of a standard broadband Internet access service, such as provided by DSL or a cable-modem.
Q7) Does the Truffle offer DHCP service on the LAN interface?
The DHCP server is enabled by default, but may be disabled, or configured to use a certain range which will not conflict with statically configured devices on your LAN.
Q8) Will I need to reconfigure my existing network to install the Truffle?
No. The Truffle supports a “pass-through” installation, for which no changes are required to the existing office data network. No changes to firewall settings or IP address re-assignment is required with the pass-through mode. The pass-through mode was designed to accommodate existing local office networks which formerly had a single WAN connection to the Internet. In the pass-through mode, the Truffle is installed in-line between the legacy WAN modem and the legacy firewall/gateway router. The Truffle is configured in this case by entering the IP address of the legacy WAN modem and the IP address of the legacy firewall/gateway router through the web-based BBNA Management Interface. Additional WAN modems can be plugged in to the Truffle for enhanced performance and reliability on an as-needed basis, and will automatically be available to the legacy data network in the office.
Q9) Besides the Broadband Bonding®, does Truffle also provide inbound DNS load-balancing?
Q10) Do I need the “Broadband Bonding Service” subscription with my Truffle device?
No. All Truffle devices will provide http downlink bonding and load-balancing for uplink and non-http traffic without requiring the monthly Broadband Bonding Service. Broadband Bonding Service will however provide additional bonding capability enabling bonding for all protocols in uplink and downlink.
Q11) How many users does Truffle support?
This depends on the Truffle model. Truffle can support offices with up to 200 employees, Truffle with performance pack add-on module can support employees with up to 2000 employees . For more than 2000 employee offices, please contact us for custom solutions.
Q12) Is Truffle a load balancing router?
Yes, Truffle is a load balancing router with WAN aggregation technology that can bond at a packet granularity.
