5.7IP Filter

IP filter is used for restricting the connection of the network in case some uncertain IP will cause errors. Only the IP set within a certain range can establish a connection. Other IPs will be rejected.

Setting up IP filter

1.Enable IP Filter Function: Check the box to enable IP filter.

2.IP:

IP addresses that are allowed to establish connections. Maximum 8 IPs are allowed.

3.Netmask:

The subnet of the IP is allowed to establish a connection. To see whether the destination IP is allowed, conduct bitwise AND operations between the allowed IP and subnet mask and destination IP and subnet mask. If the two values obtained are the same, the destination IP is allowed by the IP filter. For example, assume the IP is 192.168.0.1 and subnet mask 255.255.255.255, the only one IP allowed to establish a connection is 192.168.0.1. If the subnet mask is 255.255.255.0, the IPs allowed to establish connections will become 192.168.0.0 ~ 192.168.0.255.

5.8Static ARP Table

ARP (Address Resolution Protocol) is used for obtaining the MAC address corresponding to the IP address in data transmission. For example, there is a datum to be sent to 172.16.155.250, but you do not know the corresponding MAC address. You can use ARP to look up the MAC address by IP address, and the corresponding MAC address will be saved, so you do not need to look it up again when sending the next datum.
