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 change the router’s management port or virtual
server’s service port.
4. Make sure that the NAT DMZ service is disabled.
Q4: Some functions 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 for distinguishing the network address and the host
address. When dividing the network, the different Subnet Mask defines different subnet, and the
amount of hosts in each subnet is different.
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).
