.....do 2 IP's with same MAC Adress in my ARP Table?
i have R7000 with last FW 25015M,
now a had tweaked my ARP cache time (in W7) for longer live,
900000ms instead 300000ms and i have many stutterers in my network after research
i found mac from my Router with 192.168.1.1 and 169.254.255.1 adress registered?
Google says its a Fonera IP Range but i had nothing found to disable it in DDWRT Interface!
So i'm not ure for what is 169.254.255.1 good, but i'm sure one thing! ONE IP ONE MAC!
so please fix this.
PS.
After make ACL to denied 169.254.255.0 Range on my switch, the stutterers was gone.
the Solution for the problem is to disable UPNP service!
after that my workstation has no more double IP to one mac in the ARP-Table and do not ask my DNS-server for 1.255.254.169.in-addr.arpa!
that is not UPNP fault.
ok, i found that is APIPA with 169.254.255.1 but why with router mac address!?
and my switch shows me 2 Mac-adresses for R7000 one with ....A4 and one...A5
A4 is in Arp table on windows, A5 only by switch, Wlan 2,4 has A6, Wlan 5,0 has A7.
what is the second Mac with A5?
if i filter the A5 on the switch i have no internet, if no filter i have trouble with any MAC>IP bindings or ARP Security options.
OK!
Stupid problems solved with stupid registry key! ...by stupid user :)
"dontpinggateway=1" solves problems with loose dhcp adresses and use APIPA.
....but second MAC-Address is not resolved.....
