When this IP Passthrough option is active, after the ethernet WAN
connection is up, the router's DHCP server will offer the connection's IP
address to one LAN client. All incoming or outgoing traffic will be routed
without NAT.
Regardless the WAN connection's state, the router always binds to the LAN
IP address (Default: 192.168.50.1). So when the ethernet WAN is connected,
the LAN client could access the router's web admin by manually configuring
its IP address to the same subnet as the router's LAN IP address (e.g.
192.168.50.10).
Note: when this option is firstly enabled, the LAN client may not be able to
refresh its IP address to the ethernet WAN IP address in a timely fashion.
The LAN client may have to manually renew its IP address from DHCP
server. After this option is enabled, the DHCP lease time will be 2 minutes.
I.e. the LAN client could refresh its IP address and access the network at
most one minute after the ethernet WAN connection goes up.
This option allows you to choose whether to remain connected when this
WAN connection is no longer in the highest priority and has entered the
standby state. When Remain connected is chosen, upon bringing up this
WAN connection to active, it will be immediately available for use.
If this WAN connection is charged by connection time, you may want to set
this option to Disconnect so that connection will be made only when needed.
SpeedFusion VPN may use connected standby WAN for failover if link failure
detected on the higher priority WAN, you can set this option to Disconnect to
avoid data passing through.
If the checkbox is unticked, this option is disabled and the system will not
reply to any ICMP ping echo requests to the WAN IP addresses of this WAN
connection.
Default: ticked (Yes)
This field refers to the maximum upload speed.
This value is referenced when default weight is chosen for outbound traffic
and traffic prioritization. A correct value can result in effective traffic
prioritization and efficient use of upstream bandwidth.
This field refers to the maximum download speed.
Default weight control for outbound traffic will be adjusted according to this
value.
