Thanks for the link.
My Comcast SMC modem is set to auto and is seeing the connection as 100Mbit
Full-Duplex, which is the same for my m0n0wall router. I just now
tried experimenting with turning off auto on both the SMC and the m0n0wall
box (using config file options), then setting both to 100Mbit full-duplex
manually and didn't see any change.
