'Target IP address': Target IP address, or 0.0.0.0 if the filter is to apply
to all IP addresses.
ć
'Target subnet mask': Target subnet mask which, together with the
target IP address, determines the target network, or 0.0.0.0 if the fil-
ter is to apply to all IP addresses.
ć 'From target port' and 'To target port' define the port range for the
packets being filtered. If both values are specified as 0, the filter
applies to all target ports.
ć 'Action': This is used to define how the firewall is to treat a specific
packet. The following are your options:
ć
'Transmit packet': The packet is allowed through.
ć 'Reject packet': The packet is discarded without notification.
ć
'Discard packet': The packet is rejected and the sender is notified
accordingly.
Confirm your settings and return to the list of rules by clicking 'Save'. You can
modify the entry by clicking the source IP address. The two icons to the left
of the entry allow you to copy or delete it.
Clicking the 'Event table' opens a list containing all the logged events that
have been triggered by the rule. To make sure you can accurately trace events
in the log, check that the system time is set correctly in the router. To do so,
go to the router utility start page, then select 'Management (for advanced
users)' and then 'See date and time'.
3.3 Saving and restoring your configuration
You can save all of the settings for your MicroLink (dLAN) ISDN Router to a
file on disc simply by selecting 'Management (for advanced users)' and then
'Save configuration as file' on the entry page of the router configuration util-
ity. If at a later time your settings are inadvertently changed, you can load the
settings of the saved file into the router by clicking 'Restore configuration
from file'.
