Configuring DRO-250i
page
Transport Type - This drop-down menu allows you to specify the
transport protocol that will be filtered by the Router. You can choose from
the TCP, UDP, ICMP, IGMP, GRE, AH, ESP, and IPCOMP protocols.
Protocol - You can select from a list of commonly used protocols from
this drop-down menu. This is the equivalent of entering the correct
Transport Type and the correct port number corresponding to a given
protocol. The difference here is that the protocol is identified by name. For
example, the Simple Mail Transfer Protocol (smtp in the drop-down
menu) is used to send and receive e-mail. It uses the TCP transport
protocol and port number 25. This information will be entered for you, if
you select smtp from the Protocol drop-down menu.
Port Range - You can enter a range of port numbers for which the current
policy rules will be applied. If you have only one port number to enter,
enter it in both fields.
Direction - This allows you to specify the source of network traffic for
which the current policy entry will be applied - from the Internet
(Inbound), or from your LAN (Outbound).
IP Range Filter - The IP Range Filter page allows you to deny access to
the WAN (Internet) from specific computers on your LAN, by specifying
the computer's IP address on the WAN (Internet).
Source IP address From - This allows you to specify the first in a range
of IP addresses that the IP filter policy will be applied to. If you have only
one IP address that you want to filter, enter this address in both the From
and To fields.
Source IP address To - This allows you to specify the last in a range of
IP addresses that the IP filter policy will be applied to. If you have only
one IP address that you want to filter, enter this address in both the From
and To fields.
