Use the acl command to restrict users' access to NetMRI to a list of IP addresses or subnets, thereby reducing the likelihood of unauthorized access. By default, the appliance accepts user connections via HTTP (port 80), HTTPS (port 443), SSH (port 22), and SYSLOG (port 514). If an access control list is defined, any or all of these ports can be restricted to a specific list of IP addresses.

Syntax

The following subcommands are supported by the acl command:

...

acl [commit|list|flush|reload|accept|reject|delete|exit]

...

...

...

...

...

The accept, delete, and reject commands accept the following arguments:

accept <CIDR> 22|69|80|443|514|ssh|tftp|http|https|syslog|all

...

If at least one ACL entry is defined, all access attempts other than those specifically listed are rejected; if no ACL entries are defined, all access attempts are accepted.
Typing acl ? at the prompt provides a brief list of all options:

rgrace64-212.inca.infoblox.com> acl ?
ACL Commands
------------
?- display this list

commit - save working ACLs and make active

exit - exit ACL mode

flush - clear all working ACL entries

list - list all working ACL entries

reload - clear working entries and reload from disk

The following commands add or remove entries to the ACL to either allow or reject access from given CIDRs. The order of ACL entries is important, with the first matching
rule from top to bottom used to determine if a given host can access the system.

accept <CIDR> 22|69|80|443|514|ssh|tftp|http|https|syslog|all
reject <CIDR> 22|69|80|443|514|ssh|tftp|http|https|syslog|all
delete <CIDR> 22|69|80|443|514|ssh|tftp|http|https|syslog

where <CIDR> is formatted as A.B.C.D/NN or <IPv6 Address>/<Prefix>
