balance of packet transmission with flexible rate. It can be
divided into Auto Weighted and According to Speed Ratio.
Auto Weighted can detect the device speed
(10Mbps/100Mbps) and switch with fixed value ratio (3:7)
for packet transmission. If the transmission rate for packets
on both sides of the tunnels is the same, the value of Auto
Weighted should be 5.5. According to Speed Ratio allows
user to adjust suitable rate manually. There are 100 groups of
rate ratio for Member1:Member2 (range from 1:99 to 99:1).
Fastest – Based on available bandwidth that integrated and
considered by DrayOS system, the system can adjust
dynamically for bandwidth of both VPN tunnels. In most
cases, VPN Tunnel with high rate will use the WAN
interface which has more available bandwidth.
Below shows the algorithm for Load Balance.

addresses as starting point and ending point.
Binding Dest Port Start /End– Specify destination service
port as starting point and ending point.
Binding Fragmented – Non fragmented packets will be
bound with such tunnel table if you choose No. Fragmented
packets will be bound with such tunnel table if you choose
Yes.
Binding Protocol – Any means when the source IP,
destination IP, destination port and fragment conditions
match with the settings specified here, such binding tunnel
table can be established for TCP Service Port/UDP Service
Port/ICMP/IGMP specified here.
TCP means when the source IP, destination IP, destination
port and fragment conditions match with the settings
specified here and TCP Service Port also fits the number
here, such binding tunnel table can be established. UDP
means when the source IP, destination IP, destination port
and fragment conditions match with the settings specified
here and UDP Service Port also fits the number here, such
