Q3: What can I do if the Router with the remote management function enabled cannot be
accessed by the remote computer?
1. Make sure that the IP address of the remote computer is in the subnet allowed to remotely access
the router.
2. If the router’s management port has been modified, please log into the Router with the new
address, such as http://192.168.0.1:XX (“XX” is the new management port number).
3. Check to see if the management port has been mapped to the service port of the LAN host in the
Virtual Server function. If so, you should make a change in the router’s management port or virtual
server’s service port.
4. Make sure that the NAT DMZ service is disabled.
Q4: Some function of the Router need to define the IP address subnet with Subnet Mask. What
are the common values of the Subnet Mask?
Subnet Mask is a 32-bit binary address used to distinguish the network address and the host address.
When dividing the network, the different Subnet Mask defines different subnet, and each subnet owns
different number of hosts.
After conversed from 32-bit binary address to decimal address, the common Subnet Mask values can
be 8 (which represents the default Subnet Mask value of class A: 255.0.0.0), 16 (which represents the
default Subnet Mask value of class B: 255.255.0.0), 24 (which represents the default Subnet Mask
value of class C: 255.255.255.0) or 32 (which represents the default Subnet Mask value of class D:
255.255.255.255).
