Re: [WISPA] Lightning AGAIN
We had all sorts of lightning issues at our primary tower 15 years ago. Here's what fixed it: What we did was put a ground ring around the tower, and another ring around the building connected to that ring. 150 ground rods interconnected with #2 solid copper cad welded to the rods. Each leg of the tower is cadwelded with #2 sold and that is cadwelded to the tower ring. From that ring, we bring in #2 awg 'stingers', or connections into the building that the equipment gets grounded to. Rack, Routers, everything. Avoid ground loops. I would also recommend lightning dissapators that discharge the ion field before the strike ever happens. A ground rod with it's own #2 from the top of the tower should also get connected to the ring. Shielded ethernet cables everywhere since the emf from the lightning couples into the high impedance line and fries ports. APC UPS's on all AC, TrippLite IsoBar surge protectors or TrippLite PDUs on all AC connections. All radio cables coming from outside are shielded and grounded. All those go to grounded surge protectors. All RF cables have grounded polyphaser surge protectors (these rock). Knock on wood, not an issue since then (10+ years).

Re: [WISPA] Lightning AGAIN
Are the APC's grounded and do they have the industrial strength surge protection necessary to divert a large inrush without too much voltage rise?

Re: [WISPA] Lightning AGAIN
I've not tried Vyatta either, but I've done PFSense and got tired of waiting for features that weren't quite working in beta. RouterOS seems much more powerful and configurable to me. Though maybe you can do as much with PFSense at the CLI.

In the sense that an orange is better than a bannana, yes or no. If you are familiar with MT, run that on the PC router. I like my pfSense boxes but have found places where they just don't fit and a MikroTik or ImageStream work better. No experience with Vyatta. WISPA Wants You!

[WISPA] Lightning AGAIN
For the second week in a row lightning has got me. This time it was my main tower taking out my core cisco router, switch, AP. My luck is great. Maybe it's time to look at something besides cisco.

Good idea. I had Ethernet surge protectors but it must have jumped them.
