IDP Support Notes

8. Count the TCP offset and the length of “http://emule-prjoect.net”
9. Create User-defined policy in IDP. Login to IDP’s WEB GUI; go to IDP->User-defined. We’ll
create a user-defined policy for TCP protocol, with offset=38 bytes, matching depth=24 bytes.
Please note that the starting point of offset depends on which protocol you select. For TCP
(UDP/ICMP) protocol, the offset starts from the starting points of TCP (UDP/ICMP) payload.
IP and TCP (UDP/ICMP) headers are not included. For IP protocol, the starting point of the
offset is at the end of the IP header (IP header is not included). Press Apply button to save the
policy.
