You can filter access based on individual patterns or on groups of one or more patterns. Filters can apply to users on a specific host or to groups of hosts and users based on a a regex pattern. When pattern or pattern group is defined, you can assign a deny or allow action to the pattern or pattern group.

Specify the user name and host name in the Filter requests for section click [Deny] or [Allow].

•  action is used, licenses will be denied to machines defined in the filter–requests from all other machines will be granted. 

You can either filter by user on a specific host or define a pattern to filter by groups of hosts and users. For example, if the deny action is applied to the pattern in the example screenshot above, all users on hosts with IP addresses starting with 10.10.4 will be denied license tokens.

If both Deny and Allow actions are applied to the filters defined in License Server, the logic requires both conditions to be satisfied (i.e., an AND operator placed between the filters). For example, the license for user John will not be granted if the following filters are defined:

• ALLOW: user: John
• DENY: user: .* (i.e. all users)
