I've noticed on my Gargoyle 1.5.9 router's Connect Host Status, that several unknown hosts IPs and unknowns MACs show up on and off, each with an active UDP connection. I can't account for these computers on my small network and the IP ranges they use are not my DHCP server's range, which is 192.168.1.200-254.
Are these from my ISP and if so, why would they show up here?
Thanks!
