Hi Tom, Thanks for the response. Yes, I did have the setup you described.
To do some packet captures for early testing, I had moved the external interface of the LEAF router and the internal interface of my DSL modem to a hub that was on the same LAN as my internal network. I moved things back to the way they should have been and haven't seen the problem again. If I need to capture packets in the future, I'll get another hub to keep the network properly segmented.
