 IP Filter / MAC Filter Conflict

If there is a conflict between an IP filter and a MAC filter – in other words,

if a computer’s address is allowed by one filter but blocked by the other –

then the blocking filter takes precedence (the computer’s access is

blocked).

Lockout Policy

For increased security, the lockout policy section allows administrators to set

policies governing what happens when a user fails to log in successfully.

To set the lockout policy, check Lockout users after invalid login attempts (the

default is for Login Failures to be enabled). The meanings of the entries are

explained below.

Entry Explanation

Maximum login failures Sets the number of consecutive failed login attempts that

are permitted from a remote computer. The default is 5

times.

Timeout Sets the amount of time a remote computer must wait

before attempting to login again after it has exceeded the

number of allowed failures. The default is 3 minutes.
