I guess you should figure out *what* it is. Is it just IPv6 background chatter looking for other IPv6 devices?

Adding a rule to drop IPv6 port 547 did the trick of course. That rule is dropping 10-16Mbps on this tower right now. Should I be dropping ALL IPv6 until I am using it on the network? -Ty On Tue, Jan 6, 2015 at 10:13 AM, Ty Featherling < [email protected] > wrote: We started getting calls of slow speeds on this tower and found multiple customers that had a constant ~1.5Mbps download occuring. When I logged into the router I saw that traffic on some ports that should be idle (SiteMonitor for example). When I torch the traffic this is what I see. A single IPv6 connection on the DHCP ports. while this Mikrotik router is running 6.xx, I do NOT have the IPv6 package active since I do not have IPv6 running on my network yet. Does anyone know what this is or why it would be happening? I do not see it on other routers. Someone's router plugged into this broadcast domain and trying to serve IPv6 DHCP? I am enabling the IPv6 package so I can manage this traffic but I am very curious what I am dealing with. -Ty
