Asante Technologies FR3000 Series Connection on Demand Log, Dhcp Log for Dynamic IP Address

F.2 Connection on Demand Log

Connection-on-Demand is one of the main features of the router. If Connection- on-Demand is enabled, the router does not connect to the ISP until a client acti- vates his or her Internet applications, such as browsers, mailers etc. This feature is useful when the ISP charges by counting the connection time.

These logs tell the administrator who (and what) makes the router start its con- nection procedure. If the trigger is unwanted, try to ask the users to configure their applications or enable the Access Control feature to block them out.

1.“DOD:192.168.123.100 query DNS for www.yahoo.com”.

A host whose IP address is 192.168.123.100 sent a DNS query for FQDN “www. yahoo.com”. This query made the router start its connection procedure.

2.“DOD:TCP trigger from 192.168.123.100:1234 to 204.71.200.74:110”.

A host (192.168.123.100) sent a TCP packet to port 110 of another host on the Internet (204.71.200.74). This query made the router start its connection proce- dure. Port 110 is POP3 service. A user tried to access his/her emails. Users configure their mailers to check email periodically. It may cause the router to be triggered periodically if disconnect-when-idleis enabled.

3.“DOD:prot 1 trigger from 192.168.123.100 to 204.71.200.74”.

A host (192.168.123.100) sent an IP packet whose protocol number is 0x1 to another host (204.71.200.74) on the Internet. This query made the router start its connection procedure.

4.“DOD:triggered internally”.

The router is being configured as auto-reconnection or the system administrator forced the router to connect to Internet by clicking “Renew”, “Connect” or “Dial- Up” buttons on the Web User Interface (UI).

F.3 DHCP Log (for Dynamic IP Address)

1.“DHCP:discover(HOSTNAME)”.

The router broadcast a DISCOVER packet to seek a DHCP server. The HOST- NAME was configured at the Primary Setup page. In most case, the Host Name is not necessary. However some ISPs will require you to specify the specific Host Name they assigned you. For example, @Home.
