Security Management – Access Filter
The network Administrator can use the Access Filter to gain fine control over the Internet access and
applications available to LAN users.
• Five (5) user groups are available, and each group can have different access rights.
• All PCs (users) are in the Default group, unless assigned to another group on the Host IP
screen.
Access Group - This allows you have different access rights for different Groups of PCs.
• If you want the same restrictions to apply to everyone, select Default for the Group. In this
case, there is no need to enter any Hosts on the Host IP screen.
• If you wish to apply different restrictions on different Groups, select the desired Group. The
screen will update data for the selected Group.
ICMP – Filters - If you enable ICMP Filter that means it will block ICMP request packet type specified
by users from local host to remote side.
