f. Repeat for additional interfaces.
For example, if you want to bond a wired WAN Ethernet with a cellular modem, add two
bonded interfaces: the ETH1 Ethernet interface and Modem cellular interface.
10. Configure authentication for the WAN bonding web interface.
The WAN bonding web interface can be used to view detailed WAN bonding statistics and to
fine-tune the WAN bonding process, and is accessed via a web browser at http://ip-
address:8088, where ip-address is the IP address of the local IX20 device.
a. Click to expand Web interface.
b. For Interface password, type the unique password to log into the WAN bonding web
interface.
11. Enable Prefer TCP to use TCP channels, if the server supports them. This is useful if UDP is
blocked or throttled.
12. Click Apply to save the configuration and apply the change.

IX20 User Guide
Automatic: Automatically sets the mode to Cellular Optimized for Speed-mode for
cellular, and Ethernet for non-cellular. This is the default mode.
Cellular Optimized for Speed: A general-purpose configuration suitable for most
lines (4G, DSL, etc), with a fair tolerance for packet loss and latency.
Cellular Optimized for Latency: Another preset for mobile connections with an
even higher focus on latency.
Ethernet: A preset for direct Ethernet connections, very sensitive to latency and
packet loss.
Low Latency: Similar to Ethernet preset, but with higher tolerance for packet loss.
TCP Mode: Utilizes TCP instead of UDP. Higher throughput rate at the cost of
latency. Useful in scenarios where UDP is throttled or blocked.
