If I look at »my.gateway.address/xslt?PAGE=C_2_0
(or descriptively, Settings-tab -> Lan -> Status), I see one of my system names appear more than once with different DHCP-provided addresses in the list. Some of the duplicates are wireless uses of that system, some are wired when I had it plugged into my Ethernet LAN.
Normally, I would not care, but I was trying something this morning and decided to try and talk to that system by name (allowing the gateway to resolve the name) instead of specifying the currently in-use address for that system. Failing, I did an nslookup on the name and the gateway answered back with one of the former addresses that was assigned but not currently in use by that system. I was able to reach the system by specifying the currently in-use address.
Seeing the duplicates on the page above makes me ask if there is a way to do the equivalent of an "arp flush" on the gateway to get it drop those duplicate entries for that system name. I see a "CLEAR LIST" button on the above described page with its warning:
Clearing the device list will not clear any devices which have host application mappings. Other per-device settings you may have made (IP addresses, Content Screening,etc) will be cleared. It is recommended you only do this when instructed to do so by customer care.
So I decided that perhaps I should ask before pressing it. All that I want to do is the equivalent of "arp flush" so that the gateway rediscovers the correct address of the system and answers correctly when an nslookup is performed for a system on my LAN.--
