The action the router takes if a RIP route packet matches the IP address and subnet mask of the filter. The action can be one of the following: • deny - The ACL will deny (drop) packets that match a policy in the access list. • permit - The ACL will permit (forward) packets that match a policy in the access list. The software uses the lowest-numbered IP address configured on the port or interface as the source IP address. This parameter specifies the source IP address and mask. The IP address of the host at tbe source end. This parameter indicates the destination IP address of the denied packets. This parameter specifies the destination IP address and mask.

Configuring an extended ACL
4
ACL Number
Displays the Extended Access Control List number.
Action
The action the router takes if a RIP route packet matches the IP address and
subnet mask of the filter. The action can be one of the following:
•
deny – The ACL will deny (drop) packets that match a policy in the access list.
•
permit – The ACL will permit (forward) packets that match a policy in the access
list.
Source IP Address
The software uses the lowest-numbered IP address configured on the port
or interface as the source IP address.
Source Filter Mask
This parameter specifies the source IP address and mask.
Source Host Name
The IP address of the host at tbe source end.
Destination IP Address
This parameter indicates the destination IP address of the denied packets.
Destination Filter Mask
This parameter specifies the destination IP address and mask.
Destination Host Name
The IP address of the host at tbe destination end.
IP Precedence
This parameter is a 3-bit value in the type of service (TOS) byte of IP header used for
assigning precedence to IP packets
TOS
The 8-bit field (Type of Service) in a IP datagram header.
IP Protocol
The IP protocol can be one of the following well-known names or any IP protocol
number from 0 – 255.
•
Internet Control Message Protocol (ICMP)
•
Internet Group Management Protocol (IGMP)
•
Internet Gateway Routing Protocol (IGRP)
•
Internet Protocol (IP)
•
Open Shortest Path First (OSPF)
•
Transmission Control Protocol (TCP)
•
User Datagram Protocol (UDP)
TCP OR UDP
TCP Established
This parameter indicates an established connection. A match occurs if the TCP
datagram has the ACK or RST bits set. The non-matching case is the initial TCP
datagram to form a connection.
Source
Single Port
Enables you to specify a single source port.
Port Range
Enables you to specify the source port range from low to high.
Destination
Single Port
Enables you to specify a single destination port.
Port Range
Enables you to specify the destination port range from low to high.
Other options within the panel include:
Add
Allows you to add the Extended ACL Number.
Delete
Allows you to delete the changes made.
Reset
To undo your changes, click Reset.
Source
Source Port System
