Anyone have any solutions for protecting ethernet ports from lightning that have worked for them?
I have found a few products on Amazon but they have terrible reviews (slow speeds after install, etc)
I have a Supermicro 1U running PfSense (Dual WAN with AT&T and Comcast) that I have been running for 7+ years now and it seems like every time there is a bad storm it fries a network port on the PfSense box. The first time it fried the AT&T gateway and the built in NIC ports on the PfSense motherboard. So I installed a 4 port Intel NIC card and got it back up and running but then 6 months later it happened again and fried the 4 port card so I replaced it with a new one and it was back up and running again.
Last night we had another set of bad storms and I came in this morning to another dead 4 port NIC card.
Both internet gateways are working fine (AT&T and Comcast), it is just the 4 port network card that keeps getting fried.
Luckily I keep 2-3 extra cards on hand at the office.
I have a APC 2200VA battery backup powering everything on the network rack but it doesn’t seem to matter.
