Right now I am connecting to my work server as usual and during my connection through the VPN I always monitor the network ping through terminal and its always between 70-90. It usually never goes up beyond that, but lately I have noticed that it will sometimes go up to 1000-3000 then timeout and disconnect me for few minutes until I attempt to reconnect. Everyone in my home who uses the connection has not been engaging in unusual download or upload activity (eg. bittorrent etc).
When I disconnected the server that manages my local network at home, the problem seems to be solved for a while then it comes back, as I check my router to I find unfamiliar Mac address on my network. I am setting up a MAC address white-list to block non home wireless connections. I think this should be sufficient to solve this problem, but how might I monitor incoming/outgoing packets on my network if the white-list is ineffective.
(I'm using a Linksys E1000 router with Cisco Firmware Version: 2.1.01)
