Which type of ACL can filter based on the destination IP address?

Which type of ACL can filter based on the destination IP address?

A basic ACL can filter packets based on source IP addresses; an advanced ACL can filter packets based on both source and destination IP addresses. When the source and destination IP addresses are specified as matching conditions, the wildcard masks must be specified for them to determine address ranges.

What is ACL packet filtering?

Access control lists (ACLs) perform packet filtering to control the movement of packets through a network. Packet filtering provides security by limiting the access of traffic into a network, restricting user and device access to a network, and preventing traffic from leaving a network.

What is IP ACL?

IP ACLs classify for Layers 3 and 4. Each ACL is a set of up to ten rules applied to inbound traffic. Each rule specifies whether the contents of a given field should be used to permit or deny access to the network, and may apply to one or more of the following fields within a packet: Destination IP with wildcard mask.

What type of access control list allows you to filter by source and destination IP address source and destination port and protocol?

ACLs are packet filters that can be implemented on routers and similar devices to control the source and destination IP addresses allowed to pass through the gateway. Standard access lists can filter on source address. Extended access lists can filter ICMP, IGMP, or IP protocols at the Network layer.

Which item represent the standard IP ACL?

The standard access lists are ranged from 1 to 99 and from 1300 to 1999 so only access list 50 is a standard access list.

What is ACL and its types?

An access control list (ACL) contains rules that grant or deny access to certain digital environments. There are two types of ACLs: Filesystem ACLs━filter access to files and/or directories. Networking ACLs tell routers and switches which type of traffic can access the network, and which activity is allowed.

What is IP access list?

An access list is a sequential list that consists of at least one permit statement and possibly one or more deny statements. In the case of IP access lists, these statements can apply to IP addresses, upper-layer IP protocols, or other fields in IP packets.

How are IP packets filtered in a network?

IP packets can be filtered using Access Control Lists (ACLs) to control what traffic enters and leaves a network. ACLs can be configured and applied in inbound and outbound directions on an interface for packet filtering. Inbound ACLs check the traffic entering the interface and outbound ACLs act on traffic leaving the interface.

How are ACLs used to filter IP packets?

Inbound ACLs check the traffic entering the interface and outbound ACLs act on traffic leaving the interface. An ACL is a sequential collection of permit and deny statements that check the packets against each statement until a match is found. When a match is found, the action permit or deny specified in the statement is applied to the packet.

How does an ACL match an IP address?

When a match is found, the action permit or deny specified in the statement is applied to the packet. The ACLs have an implicit deny statement at the end, which drops all packets that do not match any statement. Standard ACL matches packets based only on source IP addresses.

How does an access control list ( Ace ) work?

The ACEs that make up an access list can be configured to detect and drop unauthorized TCP packets by allowing only the packets that have a very specific group of TCP flags set or not set. The ACL TCP Flags Filtering feature provides a greater degree of packet-filtering control in the following ways:
