General Notes
There are some router functions that, although performing as expected, might cause some confusion. These are summarized below.
General
1Default Address Mapping Rules When First Enable NAT Full Feature.
When NAT Full Feature is first enabled, two address mapping rules are added to the address mapping table. This is done to facilitate programming, and matches the default SUA rule. The rules can be deleted.
2Response to Invalid User ID or Password
When the wrong user ID or password is entered into the router login screen, no error message is displayed. Instead, the login screen is simply displayed again.
3First DHCP Address Reserved for BCM50
The first address of the DHCP Address Pool is reserved for a BCM50 in the subnet, and will not be assigned to any other equipment. Once assigned to a BCM50, it is reserved for that BCM50, and will not be assigned to any other. If the BCM50 is changed, the following command must be used to enable the router to assign the first address to a different BCM50:
ip dhcp enif0 server m50mac clear
4Login Requires Reboot
If the Administrator Timeout is set to 0, and an administration session is terminated without logging off, the router needs to be rebooted in order for the administrator to log in to the WebGUI again. Alternatively, the administrator can log in using a TelNet session, if TelNet access has been enabled in the Remote Management menu.
