Example:

offset_chunk_1 0 0xffffffff will match packet byte offset 126,127,0,1

offset_chunk_1 0 0x0000ffff will match packet byte offset,0,1

NOTE:

Only one packet_content_mask profile can be created.

With this advanced unique Packet Content Mask (also known as Packet Content Access Control List -

ACL), the

D-Link switch family can effectively mitigate some network attacks like the

common ARP Spoofing attack that is wide spread today. This is why the Packet Content

ACL is able to inspect any specified content of a packet in different protocol layers.

Click the

Select

button to select an ACL type.

Click the

Create

button

to create a profile.

Click the

<<Back

button to discard the changes made and return to the previous window.

After clicking the

Show Details

button, the following page will appear:

Click the

Show All Profiles

button to navigate back to the

Access Profile List

Page.

NOTE:

Address Resolution Protocol (ARP) is the standard for finding a host’s hardware address (MAC

address). However, ARP is vulnerable as it can be easily spoofed and utilized to attack a LAN

(i.e. an ARP spoofing attack). For a more detailed explanation on how ARP protocol works and

how to employ D-Link’s unique Packet Content ACL to prevent ARP spoofing attack, please

see Appendix E at the end of this manual.

After clicking the

Add/View Rules

button, the following page will appear:
