Surge protectors can not protect you from ground differential issues.
True enough - but 10/100 Ethernet is normally isolated by the transformer on the Ethernet transceiver. AFAIK there is not a connection between the signal lines and ground. Isolation is 1500V for the magnetics I checked. Off course all bets are off when lightning strikes since the voltage tends to be just a tad higher than 1500 volts..... Mark Radabaugh
