The first authorized IP address in the list must be your PC's (terminal) IP
address; otherwise, access from your PC is denied.

it's deleted.
3.4.6.3 Configuring the Firewall Settings
The device provides an internal firewall, allowing you (the security administrator) to define
network traffic filtering rules. You can add up to 50 ordered firewall rules. For each packet
received on the network interface, the table is scanned from the top down until a matching
rule is found. This rule can either deny (
block
) or permit (
allow
) the packet. Once a rule in
the table is located, subsequent rules further down the table are ignored. If the end of the
table is reached without a match, the packet is accepted. For detailed information on the
internal firewall, refer to the
Product Reference Manual
.
Note:
You can also configure the firewall settings using the
ini
file table parameter
AccessList (refer to ''Security Parameters'' on page 276 ).
